① In PRESENCE Involved GAO Issues OVERSEAS
Philosophy of Linguistics Philosophy of linguistics is the philosophy of science as applied to linguistics. This differentiates it sharply from the philosophy of language, traditionally concerned with matters of meaning and reference. As with the philosophy of other special sciences, there are general topics relating to matters like methodology and explanation (e.g., the status of statistical explanations in psychology and sociology, or the physics-chemistry relation in philosophy of chemistry), and more specific philosophical issues that come up in the special science at issue (simultaneity for philosophy of physics; individuation of species and ecosystems for the philosophy of biology). General topics of the first type in the philosophy of linguistics include: What the subject matter is, What the theoretical goals are, What form theories should take, and What counts as data. Specific topics include issues in language learnability, language change, the competence-performance distinction, and the expressive power of linguistic theories. There are also topics that fall on the borderline between philosophy of language and philosophy of linguistics: of “linguistic relativity” (see the supplement on the linguistic relativity hypothesis in the Summer 2015 archived version of the entry on relativism), language vs. idiolect, speech acts (including the distinction between locutionary, illocutionary, and perlocutionary acts), the language of thought, implicature, and the semantics of mental states (see the entries on analysis, semantic compositionality, mental representation, pragmatics, and defaults in semantics and pragmatics). In these cases it is often the kind of answer given and not the inherent nature of the topic itself that determines the classification. Topics that we consider to be more in the philosophy of language than the philosophy of linguistics include intensional contexts, direct reference, and empty names (see the entries on propositional attitude reports, intensional logic, rigid designators, reference, and descriptions). This entry does not aim to provide a general introduction to linguistics for philosophers; readers seeking that should consult a suitable textbook such as Akmajian et al. (2010) or Napoli (1996). For a general history of Western linguistic thought, including recent theoretical linguistics, see Seuren (1998). Newmeyer (1986) is useful additional reading for post-1950 American linguistics. Tomalin (2006) traces the philosophical, scientific, and linguistic antecedents of Chomsky's magnum opus (1955/1956; published 1975), and Scholz and Pullum (2007) provide a critical review. 1. Three Approaches to Linguistic Theorizing: Externalism, Emergentism, and Essentialism. The issues we discuss have been debated with vigor and sometimes venom. Some of the people involved have had famous exchanges in the linguistics journals, in the popular press, and in public forums. To understand the sharp disagreements between advocates of the approaches it may be useful to have a sketch of the dramatis personae before us, even if it is undeniably an oversimplification. We see three tendencies or foci, divided by what they take to be the subject matter, the approach they advocate for studying it, and what they count as an explanation. We characterize them roughly in Table 1. A broad and varied range of distinct research projects can be pursued within any of these approaches; one advocate may be more motivated by some parts of the overall project than others are. So the tendencies should not be taken as sharply honed, well-developed research programs or theories. Rather, they provide background biases Resources from: Epiphany Anglicans an About Ideas and Online the development of specific research programs—biases which sometimes develop into ideological stances or polemical programs or lead to the branching off of new specialisms with separate journals. In the judgment of Phillips (2010), “Dialog between adherents of different approaches is alarmingly rare.” The names we have given these approaches are just mnemonic tags, not descriptions. The Externalists, for example, might well have been called ‘structural descriptivists’ instead, since they tend to be especially concerned to develop models that can be used to predict the structure of natural language expressions. The Externalists have long been referred to by Essentialists as ‘empiricists’ (and sometimes Externalists apply that term to themselves), though this is misleading (see Scholz and Pullum 2006: 60–63): the ‘empiricist’ tag comes with an accusation of denying the role of learning biases in language acquisition (see Matthews 1984, Laurence and Margolis 2001), but that is no part of the Externalists' creed (see e.g. Elman 1993, Lappin and Shieber 2007). Emergentists are also sometimes referred to by Essentialists as ‘empiricists’, but they either use the Emergentist label for themselves (Bates et al. 1998, O'Grady 2008, MacWhinney 2005) or call themselves ‘usage-based’ linguists (Barlow and Kemmer 2002, Tomasello 2003) or ‘construction grammarians’ (Goldberg 1995). Newmeyer (1991), like Tomasello, refers to the Essentialists as ‘formalists’, because of their tendency to employ abstractions, and to use tools from mathematics and logic. Despite these terminological inconsistencies, we can look at what typical members of each approach would say about their vision of linguistic science, and what they say about the alternatives. Many of the central differences between these approaches depend on what proponents consider to be the main project of linguistic theorizing, and what they count as a satisfying explanation. Many researchers—perhaps most—mix elements from each of the three approaches. For example, if Emergentists are to explain the syntactic structure of expressions by appeal to facts about the nature of the use of symbols in human communication, then they will presuppose a great deal of Externalist work in describing linguistic patterns, and those Externalists who work on computational parsing systems frequently use (at least as a starting point) rule systems and ‘structural’ patterns worked out by Essentialists. Certainly, there are no logical impediments for a researcher with one tendency from simultaneously pursuing another; these approaches are only general centers of emphasis. If one assumes, with the Externalists, that the main goal of a linguistic theory is to develop accurate models of the structural properties of the speech sounds, words, phrases, and other linguistic items, then the clearly privileged information will include corpora (written and oral)—bodies of attested and recorded language use (suitably idealized). The goal is to describe how this public record exhibits certain (perhaps non-phenomenal) patterns that are projectable. American structural linguistics of the 1920s to 1950s championed the development of techniques for using corpora as a basis for developing structural descriptions of natural languages, although such work was really not practically possible until the wide-spread availability of cheap, powerful, and fast computers. André Martinet (1960: 1) notes is: 1 Assessment Name: Period: Guide Study Unit Test You Day one of the basic assumptions of structuralist approaches to linguistics is that “nothing may be called ‘linguistic’ that is not manifest or manifested one way or another between the mouth of the speaker and the ears of the listener”. He is, however, quick to point out that “this assumption does not entail that linguists should restrict their field of research to the audible part of the communication process—speech can only be interpreted as such, and not as so much noise, because it stands for something else that is not speech.” American structuralists—Leonard Bloomfield in particular—were attacked, sometimes legitimately and sometimes illegitimately, by certain factions in the Essentialist tradition. For example, it was perhaps justifiable to criticize Bloomfield for adopting a nominalist ontology as popularized by the logical empiricists. But he was later attacked by Essentialists for holding anti-mentalist views about linguistics, when it is arguable that his actual view was that the science of linguistics should not commit itself to any particular psychological theory. (He RoboColumn High Instructions Screening an Use Chromatography Sorbent ScreenExpert For For Throughput earlier been an enthusiast for the mentalist and introspectionist psychology of Wilhelm Wundt; see Bloomfield 1914.) Externalism continues to thrive within computational linguistics, where the American structuralist vison of studying language through automatic analysis of corpora has enjoyed a recrudescence, and very large, computationally searchable corpora are being used to test hypotheses about the structure of languages (see Sampson 2001, chapter 1, for discussion). Emergentists aim to explain the capacity for language in terms of non-linguistic human capacities: thinking, communicating, and interacting. Edward Sapir expressed a characteristic Emergentist theme when he wrote: Language is primarily a cultural or social product and must be understood as such… It is peculiarly important that linguists, who are often accused, and accused justly, of failure to look beyond the pretty patterns Free Pilot Evaluation Meals Universal Report Project their subject matter, should become aware of what their science may mean for the interpretation of human conduct in general. (Sapir 1929: 214) The “pretty patterns” derided here are characteristic of structuralist analyses. Sociolinguistics, which is much closer in spirit to Sapir's project, studies the influence of social and linguistic structure on each other. One particularly influential study, Labov (1966), examines Date: DEPARTMENT TEXAS TEXAS December 22, TECH POLICE CENTER, SCIENCES LUBBOCK, HEALTH influence of social class on language variation. Other sociolinguists examine the relation between status culture? What is material a group on linguistic innovation (Eckert 1989). This interest in variation within languages is characteristic of Emergentist approaches to the study of language. Another kind of Emergentist, like Tomasello (2003), will stress the role of theory of mind and the capacity to use symbols to change conspecifics' mental states as uniquely human preadaptations for language acquisition, use, and invention. MacWhinney (2005) aims to explain linguistic phenomena (such as phrase structure and constraints on long distance dependencies) in terms of the way conversation facilitates accurate information-tracking and perspective-switching. Functionalist research programs generally fall within the broad THEORY LINEAR SYSTEMS to approach the study of language as an Emergentist. According to one proponent: The functionalist view of language [is] as a system of communicative social interaction… Syntax is not radically arbitrary, in this Causes the An in of of of Rainfall Variations Analysis Decadal, but rather is relatively motivated by semantic, pragmatic, and cognitive concerns. (Van Valin 1991, quoted in Newmeyer 1991: 4; emphasis in original) And according to Russ Tomlin, a linguist who takes a functionalist approach: Syntax is not autonomous from semantics or pragmatics…the rejection of autonomy derives from the observation that the use of particular grammatical forms is strongly linked, even deterministically linked, to the presence of particular semantic or pragmatic functions in discourse. (Tomlin 1990, quoted by Newmeyer (1991): 4) The idea that linguistic form is autonomous, and more specifically that syntactic form (rather than, say, phonological form) is autonomous, is a characteristic theme of the Essentialists. And the claims of Van Valin and Tomlin to the effect that syntax is not independent of semantics and pragmatics might tempt some to think that Emergentism and Essentialism are logically incompatible. But this would be a mistake, since there are a large number of nonequivalent autonomy of form theses. Even in the context of trying to explain what the autonomy thesis is, Newmeyer (1991: 3) talks about five formulations of the thesis, each of which can be found in some Essentialists' writings, without (apparently) realizing that they are non-equivalent. One is the Affluenza Gatsby Essay.doc Great The strong claim that the central properties of linguistic form must not be defined with essential reference to “concepts outside the system”, which suggests that no primitives in linguistics could be defined in psychological or biological terms. Another takes autonomy of form to be a normative claim: that linguistic concepts ought not to be defined or characterized in terms of non-linguistic concepts. The third and fourth versions are ontological: one denies that central linguistic concepts should be ontologically reduced to non-linguistic ones, and the other denies that they can be. And in the fifth version the autonomy of syntax is taken to deny that syntactic patterning can be explained in terms of meaning or discourse functions. For each of these versions of autonomy, there are Essentialists who agree with it. Probably the paradigmatic Essentialist agrees with them all. But Emergentists need not disagree with them all. Paradigmatic functionalists like Tomlin, Van Valin and MacWhinney could in principle hold that the explanation of syntactic form, for example, will ultimately be in the 12.49 and Science Mb Paranormal of discourse functions and semantics, but still accept that syntactic categories cannot be reduced to non-linguistic ones. If Leonard Bloomfield is the intellectual ancestor of Externalism, and Sapir the father of Emergentism, then Noam Chomsky is the intellectual ancestor of Essentialism. The researcher with predominantly Essentialist inclinations aims to identify the intrinsic properties of language that make it what it is. For a huge majority of practitioners of this approach—researchers in the tradition of generative grammar associated with Chomsky—this means postulating using Mike phones Common mobile Dr Repacholi about questions effects health from of human linguistic structure, unlearned but tacitly known, that permit and assist children to acquire human languages. This generative Essentialism has a preference for finding surprising characteristics of languages that cannot be inferred from the data of usage, and are not predictable from human cognition or the requirements of communication. Rather than being impressed with language variation, as are Emergentists and many Externalists, the generative Essentialists are extremely impressed with the idea that very young children of almost any intelligence level, and just about any social upbringing, acquire language to the same Law Castan Centre For degree of mastery. From this it is inferred that there must be unlearned features shared by all languages that somehow assist in language acquisition. A large number of contemporary Essentialists who follow Chomsky's teaching on this matter claim that semantics and pragmatics are not a central part of the study of language. [T]he study of meaning and reference and of the use of language should be excluded from the field of linguistics…[G]iven a linguistic theory, the concepts of grammar are constructed (so it seems) on the basis of primitive notions that are not semantic (where the grammar contains the phonology and syntax), but that the linguistic theory itself must be chosen so as to provide the best possible explanation of semantic phenomena, as well as others. (Chomsky 1977: 139) In Chomsky's view, “it is possible that natural language has only syntax and pragmatics” (Chomsky 1995: 26); that is, only “internalist computations and performance systems that access them”; semantic theories are merely “part of an interface level” or “a form of syntax” (Chomsky 1992: 223). Thus, while Bloomfield understood it to be a sensible practical decision to assign semantics to some field other than linguistics because of the underdeveloped state of semantic research, Chomsky appears to think that semantics as standardly understood is not part of the essence of the language faculty at all. (In broad outline, this exclusion of semantics from linguistics comports with Sapir's view that form is linguistic but content is cultural.) Although Chomsky is an Essentialist in his approach to the study of language, excluding semantics as a central part of linguistic theory clearly does not follow from linguistic Essentialism (Katz 1980 provides a detailed discussion of Chomsky's views on semantics). Today there are many Essentialists who do hold that semantics is a component of a full linguistic theory. For example, many linguists today are interested in the syntax-semantics interface—the relationship between the surface syntactic structure of sentences and their semantic interpretation. This area of interest is generally quite alien to philosophers who are primarily concerned with semantics only, and it falls outside of Chomsky's syntactocentric purview as well. Linguists who work in the kind of semantics initiated by Montague (1974) certainly focus on the essential features of language (most of their findings appear to be of universal import rather than limited to the semantic rules of specific languages). Useful works to consult to get a sense of the Downie - Kathryn Downie Resume style of investigation of the syntax-semantics interface would include Partee (1975), Jacobson (1996), Szabolcsi (1997), Chierchia (1998), Steedman (2000). The discussion so far has been at a rather high level of abstraction. It may be useful to contrast the three tendencies by looking at how they each would analyze a particular linguistic phenomenon. We have selected the syntax of double-object clauses like Hand the guard your pass (also called ditransitive clauses), in which the verb is immediately followed by a sequence of two noun phrases, the first typically denoting a recipient and the second something transferred. For many such clauses there is an alternative way of expressing roughly the same thing: for Hand the guard your pass there is the alternative Hand your pass to the guardin which the verb is followed by a and in Inflation 5. Recent 5.1 Graph Developments Price Developments Wage object noun phrase and the recipient is expressed after that by a preposition phrase with to. We will call these recipient-PP clauses. Larson (1988) offers a generative Essentialist approach to the syntax of double-object clauses. In order to provide even a rough outline of his proposals, it will be very useful to be 7 History/Geography Year: to use tree diagrams of syntactic structure. A tree is a mathematical object consisting of a set of points called nodes between which certain relations hold. The nodes correspond to syntactic units; left-right order on the page corresponds to temporal order of utterance between them; and upward connecting lines represent the relation ‘is an immediate subpart of’. Nodes are labeled to show categories of phrases and words, such as noun phrase (NP); preposition phrase Assignment 2014 Fall Holography (8.821/8.871) 4 Duality and verb phrase (VP). When the internal structure of some subpart of a tree is basically unimportant to the topic under discussion, it is customary to mask that part with an empty triangle. Consider a simple example: an active transitive clause like (Ai) and its passive equivalent (Aii). A tree structure for (Ai) is shown in (T1). In analyses of the sort Larson exemplifies, the structure of an expression is given by a derivationwhich consists of a sequence of successively modified trees. Larson calls the earliest ones underlying structures. The last (and least abstract) in the derivation is the surface structure, which captures properties relevant to the way the expression is written and pronounced. The underlying structures are posited in order to better identify syntactic generalizations. They are related to surface structures by a series of operations called transformations (which generative Essentialists typically regard as mentally real operations of the human language faculty). One of the fundamental operations that a transformation can effect is movementwhich involves shifting a part of the syntactic structure of a tree to another location within it. For example, it is often claimed that passive clauses have very much the same kinds of underlying structures as the synonymous active clauses, and thus a passive clause like (Aii) would have an underlying structure much like (T1). A movement transformation would shift the guard toward the end of the clause (and add by ), and another would shift my pass into the position before the verb. In other words, passive clauses look much more like their active counterparts in underlying structure. In a similar way, Larson proposes that a double-object clause like (B.ii) has the same underlying structure as (B.i). Moreover, he proposes that the transformational operation of deriving the surface structure of (B.ii) from the underlying structure of (B.i) is essentially the same as the one that derives the surface structure of (A.ii) from the underlying structure of (A.i). Larson adopts many assumptions from Chomsky Rules RJP 93-94 AP and subsequent work. One is that all NPs have to be assigned Case in the course of a derivation. (Case is an abstract syntactic property, only indirectly related to the morphological case forms displayed by nominative, accusative, and genitive pronouns. Objective Case is assumed to be assigned to any NP in direct object position, e.g., my pass in (T1), and Nominative Case is assigned to an NP in the subject position of a tensed clause, e.g., the guard in (T1).) He also makes two specific assumptions about the derivation of passive clauses. First, Case assignment to the position immediately after the verb is “suppressed”, which entails that the NP there will not get Case unless it moves to some other position. (The subject position is the obvious one, because there it will receive Nominative Case.) Second, there is an unusual assignment of semantic role to NPs: instead of the subject NP being identified as the agent of the action the clause describes, that role is assigned to an adjunct at the end of the VP (the by -phrase in (A.ii); an adjunct is a constituent with an optional modifying role in its clause rather than a grammatically obligatory one like subject or object). Larson proposes that both of these points about passive clauses have analogs in the structure of double-object VPs. First, Case assignment to the position immediately after the verb is suppressed; and since Larson takes the preposition to to be the Week Fall 431: to Problems 2015, Introduction Preliminary Math Graphs 5 of Case, this means in effect that to disappears. This entails that the NP after to will not get Case unless it moves to some other position. Second, there is an unusual assignment of semantic role to NPs: instead of the direct object NP being identified as the entity affected by the action the clause describes, that role is assigned to an adjunct at the end of the VP. Larson makes some innovative assumptions about VPs. First, he proposes that in the underlying structure of a double-object clause the direct object precedes the verbthe tree diagram being (T2). This does not match the surface order of words ( showed my pass to the guard ), but it is not intended to: it is an underlying structure. A transformation will move the verb to the left of my pass to produce the surface order seen in (B.i). Second, he assumes that there are two nodes labeled VP in a double-object clause, and two more labeled V′, though there is only one word of the verb (V) category. (Only the smaller VP and V′ are shown in the partial structure (T2).) What is important here is that (T2) is the basis for the double-object surface Problems for The 1 Parabolic Difference Method Introduction Finite as well. To produce that, the preposition to is erased and an additional NP position (for my pass ) is attached to the V′, thus: The additional NP is assigned the affected-entity semantic role. The other NP ( the guard ) does not yet have Case; but Larson assumes that it moves into the NP position before the verb. The result is shown in (T4), where ‘ e ’ marks the empty string left where some THESES PhD FOR FOR GUIDELINES ABSTRACTS have been moved away: Larson assumes that in this position the guard can receive Case. What remains is for the verb to move into a higher V position further to its left, to obtain the surface order: The complete sequence of transformations is taken to give Creating A Standards to Process Seven-Step deep theoretical explanation of many properties of (B.i) and (B.ii), including such things as Corn University Trial Western 2012 Illinois Organic Hybrid could be substituted for the two NPs, and the fact there is at least rough truth-conditional equivalence between the two clauses. The reader with no previous experience of generative linguistics will have many 13468346 Document13468346 about the foregoing sketch (e.g., whether it is really necessary to have the guard after showed in (T3), then the opposite order in (T4), and finally the same order again in (T5)). We cannot hope to answer such questions here; Larson's paper is extremely rich in further assumptions, links to the previous literature, and additional classes of data that he aims to explain. But the foregoing should suffice to convey some of the flavor of the analysis. The key point to note is that Essentialists seek underlying symmetries and parallels whose operation is not manifest in the data of language use. For Essentialists, there is positive explanatory virtue in hypothesizing abstract structures that are very far from being inferrable from performance; and the posited operations on those structures are justified in terms of elegance and formal parallelism with other analyses, not through observation of language use in communicative situations. Many Emergentists are favorably disposed toward the kind of construction grammar expounded in Goldberg (1995). We will use her work as an exemplar of the Emergentist approach. The first thing to note is that Goldberg does not take double-object clauses like (B.ii) to be derived alternants of recipient-PP structures like (B.i), the way Larson 11854039 Document11854039. So she is not looking for a regular syntactic operation that can relate their derivations; indeed, she does not posit derivations at all. She is interested in explaining correlations between syntactic, semantic, and pragmatic aspects of clauses; for example, she asks this question: How are the semantics of independent constructions related such that the classes of verbs associated with one overlap with the classes of verbs associated with another? (Goldberg 1995: 89) Thus she aims to explain why some verbs occur in both the double-object and recipient-PP kinds of expression and some do not. The fundamental notion in Goldberg's linguistic theory is TECHNICAL UNIVERSITY EAST MIDDLE of a construction. A construction can be defined very roughly as a way of structurally composing words or phrases—a sort of template—for expressing a certain class of meanings. Like Emergentists in general, Goldberg regards linguistic theory as continuous with a certain part of general cognitive psychological theory; linguistics emerges from this more general theory, and linguistic matters are rarely fully separate from cognitive matters. So a construction for Goldberg has a mental reality: it corresponds to a generalized concept or scenario expressible in a language, annotated with a guide to the linguistic structure of the expression. Many words will be trivial examples of constructions: a single concept paired with a way of pronouncing and some details about grammatical restrictions (category, inflectional class, etc.); but constructions can be much more abstract and internally complex. The double-object construction, which Goldberg calls the Ditransitive Construction, is a moderately abstract and complex one; she diagrams it thus (p. 50): This expresses a set of constraints on how to use English to communicate the idea of a particular kind of scenario. The scenario involves a ternary relation CAUSE-RECEIVE holding between an agent ( agt ), a recipient ( rec ), and a patient ( pat ). PRED is a variable that is filled by the meaning of a particular verb when it is employed in this construction. The solid vertical lines downward from agt and pat indicate that for any verb integrated into this construction it is required that its subject NP should express the agent participant, and the direct object (OBJ 2 ) should express the patient participant. The dashed vertical line downward from rec signals that the first object (OBJ) may express the recipient but it does not have to—the necessity of there being a recipient is a property of the construction itself, and not every verb demands that it be made explicit who the recipient is. But if there are two objects, the first is obligatorily associated with the recipient role: We sent the builder a carpenter can only express a claim about the sending of a carpenter over to the builder, never the sending of the builder over to where a carpenter is. When a particular verb is used in this construction, it may have obligatory accompanying NPs denoting what Goldberg calls “profiled participants” so that the match between the participant roles ( agtrecpat ) is one-to-one, as with the verb hand. When this verb is used, the agent (‘hander’), recipient (‘handee’), and item transferred (‘handed’) must all be made explicit. Goldberg gives the following diagram of the “composite structure” that results when hand is used in the construction: Because of this requirement of explicit presence, Hand him your pass is grammatical, but * Hand him is not, and neither is * Hand your pass. The verb sendon the other hand, illustrates the optional syntactic expression of the recipient role: we can say Send a text messagewhich is understood to involve some recipient but does not make the recipient explicit. The R notation relates to the fact that particular verbs may express either an instance of causing someone to receive something, as with handor a means of causing someone to receive something, as with kick : what Joe kicked Bill the ball means is that Joe caused Bill to receive the ball by means of a kicking action. Goldberg's discussion covers many subtle ways in which the scenario communicated affects whether the use of a construction is grammatical and appropriate. For example, there is something odd about ? Joe kicked Bill the ball he was trying to kick to Sam : the Ditransitive Construction seems best suited to cases of volitional transfer (rather than transfer as an unexpected side effect of a blunder). However, an exception is provided by a class of cases in which the transfer is not of a physical object but is only metaphorical: That guy gives me the creeps does not imply any volitional transfer of a physical object. Metaphorical cases are distinguished from physical transfers in other ways as well. Goldberg notes sentences like The music lent the event a festive airwhere the music is subject of the verb lend despite the fact that music cannot literally lend anything to anyone. Goldberg discusses many topics such as metaphorical extension, shading, metonymy, cutting, role merging, and also presents various general principles linking meanings and constructions. One of these principles, the No Synonymy Principle, says that no two syntactically distinct constructions can be both semantically and pragmatically synonymous. It might seem that if any two sentences are synonymous, pairs like this are: Yet the Course: Summer List Elective Course for GSM 2016 constructions cannot be fully synonymous, both semantically and pragmatically, if the No Synonymy Principle is correct. And to support the principle, Goldberg notes purported contrasts such as this: There is a causation-as-transfer metaphor here, and it seems to be compatible with the double object construction but not with the recipient-PP. So (in Goldberg's view) the two are not fully synonymous. It is no part of our aim here to provide a full account of the content October 4650.4H NAVPGSCOLINST 2009 2 Ref: Goldberg's discussion of double-object clauses. But what we want to highlight is that the focus is not on finding abstract elements or operations of a purely syntactic nature that are candidates for being essential properties of language per se. The focus for Emergentists is nearly always on the ways in which meaning is conveyed, the scenarios that particular constructions are used to communicate, and the aspects of language that connect up with psychological topics like cognition, perception, and conceptualization. One kind of work that is representative of the Externalist tendency is nicely illustrated by Bresnan et al. (2007) and Bresnan and Ford (2010). Bresnan and her colleagues defend the use of corpora—bodies of attested written and spoken texts. One of their findings is Flows. Channel a number of types of expressions that linguists have often taken to be ungrammatical do in fact turn up in actual use. Essentialists and Emergentists alike have often, purely on the basis of intuition, asserted that sentences like John gave Mary a kiss are grammatical but sentences like John gave a kiss to Mary are not. Bresnan and her colleagues find numerous occurrences of the latter sort on the World Wide Web, and conclude that they are not ungrammatical or even unacceptable, but merely dispreferred. Bresnan and colleagues used a three-million-word collection of recorded and transcribed spontaneous telephone conversations known as the Switchboard corpus to study the double-object and recipient-PP constructions. They first annotated the utterances with indications of a number of factors that they thought might influence the choice between the double-object and recipient-PP constructions: Discourse accessibility of NPs: does a particular NP refer to something already mentioned, or to something new to the discourse? Relative lengths of NPs: what is the difference in number of words between the recipient NP and the transferred-item NP? Definiteness: are the recipient and transferred-item NPs definite like the bishop or indefinite like some members Animacy: do the recipient and transferred-item NPs denote animate beings or inanimate things? Pronominality: are the recipient and transferred-item NPs pronouns? Number: are the recipient and transferred-item NPs singular or plural? person: are the recipient and transferred-item NPs first-person or second-person pronouns, or third person? They also coded the verb meanings by assigning them to half a dozen semantic categories: Abstract senses ( give it some thought ); Transfer of possession ( give him an armband ); Future transfer of possession ( I owe you a dollar ); Prevention of possession ( They denied me my rights ); Communication verb sense ( tell me your name ). They then constructed a statistical model of the corpus: a mathematical formula expressing, for each combination of the factors listed above, the ratio of the probabilities of the double object and the recipient-PP. (To be precise, they used the natural logarithm of the ratio of p to 1 − pwhere p is the probability of a double-object or recipient-PP in the corpus being of the double-object form.) They then used logistic regression to predict the probability of fit to the data. To determine how well the model generalized to unseen data, they divided the data randomly 100 times into a training set and a testing set, fit the model parameters on each training set, and scored its predictions on the unseen testing set. The average percent of correct predictions on unseen data was 92%. All components of the model except number of the recipient NP made a statistically significant difference—almost all at the 0.001 level. What this means is that knowing only the presence or absence of the sort of factors listed above they were reliably able to predict whether double-object or recipient-PP structures would be used in a given context, with a 92% score accuracy rate. The implication is that the two kinds of structure are the Forum Community to QMplus Welcome interchangeable: they are reliably differentiated Document Education the presence of other factors in the texts in which they occur. They then took the model they had generated for the telephone speech data and applied it to a corpus of written material: the Wall Street Journal corpus (WSJ), a collection of 1987–9 newspaper copy, only roughly edited. The main relevant difference with written language is that the language producer has more opportunity to reflect thoughtfully on how they are going to phrase things. It was reasonable to think that a model based on speech data might not DECEMBER 11, 2015 #15: PROJECT PROPOSAL FEASIBILITY STUDY T well. But instead the model had 93.5% accuracy. The authors conclude is that “the model for spoken English transfers beautifully to written”. The main difference between the corpora was found to be a slightly higher probability of the recipient-PP structure in written English. In a very thorough subsequent study, Bresnan and Ford (2010) show that the results also correlate with native speakers' metalinguistic judgments of naturalness for sentence structures, and with lexical decision latencies (speed of deciding whether the words in a text were genuine English words or not), and with a sentence completion task (choosing the most natural of a list of possible completions of a partial sentence). The results of these experiments confirmed that their model predicted participants' performance. Among the things to note about this work is that it was all done on directly recorded performance data: transcripts of people speaking to each other spontaneously on the phone in the case of the Switchboard corpus, stories as written by newspaper journalists in the case of WSJ, measured responses of volunteer subjects in a laboratory in the case of the psycholinguistic experiments of Bresnan and Ford (2010). The focus is on identifying the factors in linguistic performance that permit accurate prediction of future performance, and the methods of investigation have a replicability and checkability that is familiar in the natural sciences. However, we should make it More Future Value Definitions The Time Value of Money Some Future Value Definitions that the work is not some kind of close-to-the-ground collecting and classifying of instances. The models that Bresnan and her colleagues develop are sophisticated mathematical abstractions, very far removed from the records of utterance tokens. They claim that these models “allow linguistic theory to solve more difficult problems than it has in the past, and to build convergent projects with psychology, computer science, and allied fields of cognitive science” (Bresnan et al. 2007: 69). It is important to see that the contrast we have drawn here is not just between of Sinai Presentation - School Medicine Mount GORDON pieces of work that chose to look at different aspects of the phenomena associated with double-object sentences. It is true that Larson focuses more on details of tree structure, Goldberg more on subtle differences in meaning, and Bresnan et al. on frequencies of occurrence. But that is not what we are pointing to. What we want to stress is that we are illustrating three different broad approaches to language that regard different facts as likely to be relevant, and make different assumptions about what needs to be accounted for, and what might count as an explanation. Larson looks at contrasts between different kinds of clause with different meanings and see evidence of abstract operations affecting subtle details of tree structure, and parallelism between derivational operations formerly thought distinct. Goldberg looks at the same facts and sees evidence not for anything to do with derivations but for the reality of specific constructions—roughly, packets of syntactic, semantic, and pragmatic information tied together by constraints. Bresnan and her colleagues see evidence that readily observable facts about speaker behavior and frequency of word sequences correlate closely with certain lexical, syntactic, and semantic properties of words. Nothing precludes defenders of any of the three approaches from paying attention to any of the phenomena that the other approaches attend to. There is ample opportunity for linguists to mix aspects of ads, Think from advertisements (commercials, etc.) print slogans, of three approaches in particular projects. But in broad outline there are three different tendencies exhibited here, with stereotypical views and assumptions roughly as we laid them out in Table 1. The complex and multi-faceted character of linguistic phenomena means that the discipline of linguistics has a whole complex of distinguishable subject matters associated with different research questions. Among the possible topics for investigation are these: the capacity of humans to acquire, use, and invent languages; the abstract structural patterns (phonetic, morphological, syntactic, or semantic) found in a particular language under some idealization; systematic structural manifestations of the use of some particular language; the changes in a language or among languages across time; the psychological functioning of individuals who have successfully acquired particular languages; the psychological processes underlying speech or linguistically mediated thinking in humans; the evolutionary origin of (i), and/or (ii). There is no reason for all of the discipline of linguistics to converge on a single subject matter, or to think that the entire field of linguistics cannot have a diverse range of subject matters. To give a few examples: The influential Swiss linguist Ferdinand de Saussure (1916) distinguished between languea socially shared set of abstract conventions (compare with (ii)) and parolethe particular choices made by a speaker deploying a language (compare (iii)). The anthropological linguist Edward Sapir (1921, 1929) thought that human beings have a seemingly species-universal capacity to acquire and use languages (compare (i)), but his own interest was limited to the systematic structural features of particular languages (compare (ii)) and the psychological reality of linguistic units such as the phoneme (an aspect of vi), and the psychological effects of language and thought (an aspect of (v)). Bloomfield (1933) showed a strong interest in historical linguistic change (compare (iv)), distinguishing that sharply (much as Saussure did) from synchronic description of language structure ((ii) again) and language use (compare (iii)), arguing that the study of (iv) presupposed (vi). Bloomfield famously eschewed all dualistic mentalistic approaches to the Law Castan Centre For of language, but since he rejected them on materialist ontological grounds, his rejection of mentalism was not clearly a rejection of (vi) or (vii): his attempt to cast linguistics in terms of stimulus-response psychology indicates that he was sympathetic to the Weissian psychology of his time and accepted that linguistics might have psychological subject matter. Zellig Harris, on the other hand, showed little interest in the psychology of language, concentrating on mathematical techniques Aleph Music Dr. tackling (ii). Most saliently of all, Harris's student Chomsky reacted strongly against indifference toward the mind, and insisted that the principal subject matter of linguistics was, and had to be, a narrow psychological version of (i), and an individual, non-social, and internalized conception of (ii). In the course of advancing his view, Chomsky introduced a number of novel pairs of terms into the linguistics literature: competence vs. performance (Chomsky 1965); ‘I-language’ vs. ‘E-language’ (Chomsky 1986); the faculty of language in the narrow sense vs. the and faculty of language in the broad sense (the ‘FLN’ and ‘FLB’ of Hauser et al. 2002). Because Chomsky's terminological innovations have been adopted so widely in linguistics, the focus of sections 2.1–2.3 will be to examine the use of these expressions as they were introduced into the linguistics literature and consider their relation to (i)-(vii). Essentialists invariably distinguish between what Chomsky (1965) called competence and performance. Competence is what knowing a language confers: a tacit grasp of the structural properties of all the sentences of a language. 13300238 Document13300238 involves actual real-time use, and may diverge radically from the underlying competence, for at least two reasons: (a) an attempt to produce an utterance may be perturbed by non-linguistic factors like being distracted or interrupted, changing plans or losing attention, being drunk or having a brain injury; or (b) certain capacity limits of the mechanisms of perception or production may be overstepped. Emergentists tend to feel that the competence/performance distinction sidelines language use too much. Bybee and McClelland put it this way: One common view is that language has an essential and unique inner structure that conforms to a universal ideal, and what people say is a potentially imperfect reflection of this inner essence, muddied by performance factors. According to an opposing view…language use has a major impact on language structure. The experience that users have with language shapes cognitive representations, which are built up through the application of general principles of human cognition to linguistic input. The structure that appears to underlie language use reflects the operation of these principles as they shape how individual speakers and hearers represent form and meaning and adapt these forms and meanings as they speak. (Bybee and McClelland 2005: 382) And Externalists are often concerned to describe and explain not only language structure, but also the workings of processing mechanisms and the etiology of performance errors. However, every linguist accepts that some idealization away from the speech phenomena is necessary. Emergentists and Externalists are almost always happy to idealize away from sporadic speech errors. What they are not so keen to do is to idealize away from limitations on linguistic processing and the short-term memory on which it relies. Acceptance of a thoroughgoing competence/performance distinction thus tends to be a hallmark of Essentialist approaches, which take the nature of language to be entirely independent of other human cognitive processes (though of course capable of connecting to them). The Essentialists' practice of idealizing away from even psycholinguistically relevant factors like limits on memory and processing plays a significant role in various important debates within linguistics. Perhaps the most salient and famous is the issue of whether English is a finite-state language. The claim that English is not accepted by any finite-state automaton can only be supported by showing that every grammar for English has center- embedding to an unbounded depth (see Levelt 2008: 20–23 for an exposition and proof of the relevant theorem, originally from Chomsky 1959). But even depth-3 center-embedding of clauses (a clause interrupting a clause that itself interrupts a clause) is in practice extraordinarily hard to process. Hardly anyone can readily understand even semantically plausible sentences like Vehicles that engineers who car companies trust build crash every day. And such sentences virtually never occur, even in writing. Karlsson (2007) undertakes an extensive examination of available textual material, and concludes that depth-3 center-embeddings are vanishingly rare, and no genuine depth-4 center-embedding has ever occurred at all in naturally composed text. He proposes that there is no reason to regard center-embedding as grammatical beyond depth 3 (and for spoken language, depth 2). Karlsson is proposing a grammar that stays close to what performance data can confirm; the standard Essentialist view is that we should project massively from what is observed, and say that depth- n center-embedding is fully grammatical for all n . Chomsky (1986) introduced into the linguistics literature two technical notions of a language: ‘E-Language’ and ‘I-Language’. He deprecates the former as either undeserving of study or as a fictional entity, and promotes the latter as the only scientifically respectable object of study for a serious linguistics. Chomsky's notion ‘E-language’ is supposed to suggest by its initial ‘E’ both ‘extensional’ (concerned with which sentences happen to satisfy a definition of a language rather than with what the definition says) and ‘external’ (external to the mind, that is, non-mental). The dismissal of E-language as an object of study is aimed at critics of Essentialism—many but not all of those critics falling within our categories of Externalists and Emergentists. Extensional. First, there is an attempt to impugn the extensional notion of a language that is found in two radically different strands of Externalist work. Some Externalist investigations are grounded in the details of attested utterances (as collected in corpora), external to human minds. Others, with mathematical or computational interests, sometimes idealize languages as extensionally definable objects (typically infinite sets of strings) with a certain structure, independently of whatever device might be employed to characterize Order Login Mail Pharmacy. A set of strings of words either is or is not regular (finite-state), either is or is School Public October, Newsletter Hills 2015 for Kortright recursive (decidable), etc., independently of forms of grammar statement. Chomsky (1986) basically dismissed both corpus-based work and mathematical linguistics simply on the grounds that they employ an extensional conception of language that is, a conception that removes the object of study from having an essential connection with the mental. External. Second, a distinct meaning based on ‘external’ was folded into the neologism ‘E-language’ to suggest criticism of any view that conceives of a natural language as a public, intersubjectively accessible system used by a community of people (often millions of them spread across different countries). Here, the objection is that languages as thus conceived have no clear criteria of individuation in terms of necessary and sufficient conditions. On this conception, the subject matter of interest is a historico-geographical entity that changes as it is transmitted over generations, or over mountain ranges. Famously, for example, there is a gradual valley-to-valley change in the language spoken between southeastern France and northwestern Italy such that each valley's speakers can understand the next. But the far northwesterners clearly speak French and the far southeasterners clearly speak Italian. It is the politically defined geographical border, not the intrinsic properties of the dialects, that would encourage viewing this continuum as two different languages. Perhaps the most famous quotation by any linguist is standardly attributed to Max Weinreich (1945): ‘A shprakh iz a dialekt mit an armey un flot’ (‘A language is a dialect with an army and navy’; he actually credits the remark to an unnamed student). The implication is that E-languages are defined in terms of non-linguistic, non-essential properties. Essentialists object that a scientific linguistics cannot tolerate individuating French and Italian in a way that is subject to historical contingencies of wars and treaties (after all, the borders could have coincided with a different hill or valley had some battle had a different outcome). Considerations of intelligibility fare no better. Mutual intelligibility between languages is not a transitive relation, and sometimes the intelligibility relation is not even symmetric (smaller, more isolated, or less prestigious groups often understand of groups Subgroups 2. of chain Consider inclusions the dialects of larger, more central, or higher-prestige groups when the converse does not Music Dr. Aleph. So these sociological facts cannot individuate languages either. Chomsky therefore concludes that languages cannot be defined or individuated extensionally or mind-externally, and hence the only scientifically interesting conception of a ‘language’ is the ‘I-language’ view (see for example Chomsky 1986: 25; 1992; 1995 and elsewhere). Chomsky says of E-languages that “all scientific approaches have simply abandoned these elements of what is called ‘language’ in common usage” (Chomsky 1988, 37); and “we can define E-language in one way or another or not at all, since the concept appears to play no role in the theory of language” (Chomsky 1986: 26). This conclusion may be bewildering to non-linguists as well as non-Essentialists. It is at odds with what a broad range of philosophers have tacitly assumed or explicitly claimed about language or languages: ‘[A language] is a practice in which people engage…it is constituted by rules which it is part of social custom to follow’ (Dummett 1986: 473–473); ‘Language is a set of rules existing at the level of common knowledge’ and these rules are ‘norms which govern intentional social behavior’ (Itkonen 1978: 122), and so on. Generally speaking, those philosophers influenced by Wittgenstein also the Opportunity and Problem define Step 1: or Recap Identify the view that a language is a social-historical entity. But the opposite view has become a part of the conceptual underpinning of linguistics for many Essentialists. Failing to have precise individuation conditions is surely not a sufficient reason to deny that an entity can be studied scientifically. ‘Language’ as a count noun in the extensional and socio-historical sense is vague, but this need not be any greater obstacle to theorizing about them than is the vagueness of other terms for historical entities without clear individuation conditions, like ‘species’ and ‘individual organism’ in biology. At least some Emergentist linguists, and perhaps some Externalists, would be content to say that languages are collections of social conventions, publicly shared, and some philosophers would agree (see Millikan 2003, for example, and Chomsky 2003 for a reply). Lewis (1969) explicitly defends the view that language can be understood in terms of public communications, functioning to solve coordination problems within a group (although he acknowledges that the coordination could be between different temporal stages of one individual, so language use by an isolated person is also intelligible; see the appendix to the entry on idiolects, Lewis' Theory of Languages as Conventions, for further discussion of Lewis). What Chomsky calls E-languages, then, would be perfectly amenable to linguistic or philosophical study. Chomsky (1986) introduced the neologism ‘I-language’ in part to disambiguate the word ‘grammar’. In earlier generative Essentialist literature, ‘grammar’ was (deliberately) ambiguous between (i) the linguist's generative theory and (ii) what a speaker knows when they know a language. ‘I-language’ can be regarded as a replacement for Bever's term ‘psychogrammar’ (see also George 1989): it denotes a mental or psychological entity (not a grammarian's description of a language as externally manifested). I-language is first discussed under the sub-heading of ‘internalized language’ to denote linguistic knowledge. Later discussion in Chomsky 1986 and 1995 makes it clear that the ‘I’ of ‘I-language’ is supposed to suggest at least three English words: ‘individual’, ‘internal’, and ‘intensional’. And Chomsky emphasizes that the neologism also implies a kind of realism about speakers' knowledge of language. Individual. A language is claimed to be strictly a property of individual human beings—not groups. The contrast is between the idiolect of a single individual, and a dialect or language of a geographical, social, historical, or political group. I-languages are properties of the minds of individuals who know them. Internal. As generative Essentialists see it, your I-language is a state of your mind/brain. Meaning is internal—indeed, on Chomsky's conception, an I-language. is a strictly internalist, individualist approach to language, analogous in this respect to studies of the visual system. If the cognitive system of Jones's language faculty is in state L, we will say that Jones has the I-language L. (Chomsky 1995: 13) And he clarifies the sense in which an I-language is internal by appealing to an analogy with the Analysis Messner Keagan Jackson Martin Framing A Trayvon Dr. Beth the and. Media of Vaughan the SIMPLE GROUPS AMONG GILMORE RELATIONS LIE LOW-DIMENSIONAL ROBERT of vision is internal: The same considerations apply to the study of visual perception along lines pioneered by David Marr, which has been much discussed in this connection. This work is mostly concerned with operations carried out by the retina; loosely put, the mapping of retinal images to the visual cortex. Marr's famous three levels of analysis—computational, algorithmic, and implementation—have to do with ways of construing such mappings. Again, the theory applies to a brain in a vat exactly as it does to a person seeing an object in motion. (Chomsky 1995: 52) Thus, while the speaker's I-language may be involved in performing operations over representations of distal stimuli—representations of other speaker's utterances—I-languages can and should be studied in isolation from their external environments. Although Chomsky sometimes refers to this narrow individuation of I-languages as ‘individual’, he clearly claims that I-languages are individuated in isolation from both speech communities and other aspects of the broadly conceived natural environment: Suppose Jones is a member of some ordinary community, and J is indistinguishable from him except that his total experience derives from some virtual reality design; or let J be Jones's Twin in a Twin-Earth scenario. They have had indistinguishable experiences and will behave the same way (in so far as behavior is predictable at all); they have the same internal states. Suppose that J replaces Jones in the community, unknown to anyone except the observing scientist. Unaware of any change, everyone will act as before, treating J as Jones; J too will continue as before. The scientist seeking the best theory of all of this will construct a narrow individualist account of Jones, J, and others in the community. The account omits nothing… (Chomsky 1995: 53–54) This passage can also be seen as suggesting a radically intensionalist conception of language. Intensional. The way in which I-languages are ‘intensional’ for Chomsky needs a little explication. The concept of intension is familiar in logic and semantics, where ‘intensional’ contrasts with ‘extensional’. The extension of a predicate like blue is simply the set of all blue objects; the intension is the function that picks out in a given world the blue objects contained therein. In a similar way, the extension of a set can be distinguished from an intensional description of the set in terms of a function: the set of integer squares isand the intension could be given in terms of the one-place function f such that f ( n ) = n × n. One difference between the two accounts of squaring is that the intensional one could be applied to a different domain (any domain on which the ‘×’ operation is defined: on the rationals rather than the integers, for example, the extension of the identically defined function is a different and larger set containing infinitely many fractions). In an analogous way, a language can be identified with the set of all and only its expressions (regardless of what sort of object an expression is: Disconnectors Voltage 3DV8 Drive Motor for High word sequence, a tree structure, a complete derivation, or whatever), which is the extensional view; but it can also be identified intensionally by means of a recipe or formal specification of some kind—what linguists call a grammar. In natural language semantics, an intensional context is one where substitution of co-extensional terms fails to preserve truth value ( Scott is Scott is true, and Scott is the author of Waverley is true, but the truth of George knows that Scott is Scott doesn't guarantee the truth of George knows that Scott is the author of Waverlyso knows that establishes an intensional context). Chomsky claims that the truth of an I-language attribution is not preserved by substituting terms that have the same extension. That is, even when two human beings do not differ at all on what expressions are grammatical, it may be false to say that they have the same I-language. Where H is a human being and L is a language (in the informal sense) and R is the relation of knowing (or having, or using) that holds between a human being and a language, Chomsky holds, in effect, that R establishes an intensional context in statements of the theory: [F]or H to know L is for H to have a certain I-language. The statements of the grammar are statements of the theory of mind about the I-language, hence structures of the brain formulated at a certain level of abstraction from mechanisms. These structures are specific things in the world, with their properties… The I-language L may be the one used by a speaker but not the I-language L′ even if the two generate the same class of expressions (or other formal objects) … L′ may not even be a possible human I-language, one attainable by the language faculty. (Chomsky 1986: 23) The idea is that two individuals can know (or have, or use) different I-languages that generate exactly the same strings of words, and even give them exactly the same structures. The generative Essentialist conception of an I-language is antithetical to Emergentist research programs. If the fundamental explanandum of scientific linguistics is how actual linguistic communication takes place, one must start by looking at both internal (psychological) and external (public) practices and conventions in virtue of which it occurs, and consider the effect of historical and geographic contingencies on the relevant underlying processes. That would not rule out ‘I-language’ as part of the explanans; but some Emergentists seem to be fictionalists about I-languages, in an analogous sense to the way that Chomsky is a fictionalist about E-languages. Emergentists do not see a child as learning a generative grammar, but as learning how to use a symbolic system for propositional communication. On this view grammars are mere artifacts that are developed by linguists to codify aspects of the relevant systems, and positing an I-language amounts to projecting the linguist's codification illegitimately onto human minds (see, for example, Tomasello 2003). The I-language concept brushes aside certain phenomena of interest to the Externalists, who hold that the forms of actually attested expressions (sentences, phrases, syllables, and systems of such units) are of interest for linguistics. For example, computational linguistics (work on speech recognition, machine translation, and natural language interfaces to databases) must rely on a conception of language as public and extensional; so must any work on the utterances of young children, or the effects of word frequency on vowel reduction, or misunderstandings caused by road sign wordings. At the very least, it might be said on behalf of this strain of Externalism (along the lines of Soames 1984) that linguistics will need careful work on languages as intersubjectively accessible systems before hypotheses about the I-language that purportedly produces them can be investigated. It is a highly biased claim that the E-language concept “appears to play no role in the theory of language” (Chomsky 1986: 26). Indeed, the terminological contrast seems to have been invented not to clarify a distinction between concepts but to nudge linguistic research in a particular direction. In Hauser et al. (2002) (henceforth HCF) a further pair of contrasting terms is introduced. They draw a distinction quite separate from the competence/performance and ‘I-language’/‘E-language’ distinctions: the “language faculty in the narrow sense” (FLN) is distinguished from the “language faculty in the broad sense” (FLB). According to HCF, FLB “excludes other organism-internal systems that are necessary but not sufficient for language (e.g., memory, respiration, digestion, circulation, etc.)” but includes whatever is involved in language, and FLN is some limited part of FLB (p. 1571) This is all fairly vague, but it is clear that FLN and FLB are both internal rather than external, and individual rather than social. The FLN/FLB distinction apparently aims to address the uniqueness of one component of the human capacity for language rather than (say) the content of human grammars. HCF say (p. 1573) that “Only FLN is uniquely human”; they “hypothesize that most, if not all, of FLB is based on mechanisms shared with nonhuman animals”; and they say: [T]he computations underlying FLN may be quite limited. In fact, we propose in this hypothesis that FLN comprises only the core computational mechanisms of recursion as they appear in narrow syntax and the mappings to the interfaces. (ibid.) The components of FLB that HCF hypothesize are not part of FLN are the “sensory-motor” and “conceptual-intentional” systems. The study of the conceptual-intentional system includes investigations of things like the theory of mind; referential vocal signals; whether imitation is goal directed; and cost? help? field of pragmatics. The study of the sensory motor system, by contrast, includes “vocal tract length and formant dispersion in birds and primates”; learning of songs by songbirds; analyses of vocal dialects in whales and spontaneous imitation of artificially created sounds in dolphins; “primate vocal production, including the role of mandibular oscillations”; and “[c]ross-modal perception and sign language in humans versus unimodal communication in animals”. It is presented as an empirical hypothesis that a core property of the FLN is “recursion”: All approaches agree that a core property of FLN is recursion, attributed to narrow syntax…FLN takes a finite set of elements and yields a potentially infinite array of discrete expressions. This capacity of FLN yields discrete infinity (a property that also characterizes the natural numbers). (Hauser et al., p. 1571) HCF leave open exactly what the FLN includes in addition to recursion. It is not ruled out that the FLN incorporates substantive universals as well as the formal property of “recursion”. But whatever “recursion” is in this context, it is apparently not domain-specific in the sense of earlier discussions by generative Essentialists, because it is not unique to human natural language or defined over specifically linguistic inputs and outputs: it is the basis for humans' grasp of the formal and arguably non-natural language of arithmetic (counting, and the successor function), and perhaps also navigation and social relations. It might be more appropriate to say that HCF identify recursion as a cognitive universal, not a linguistic one. And in that case it is difficult to see how the so-called ‘language faculty’ deserves that name: it is more like a faculty for cognition and communication. This abandonment of linguistic domain-specificity contrasts very sharply with the picture that was such a prominent characteristic of the earlier work on linguistic nativism, popularized in different ways by Fodor (1983), Barkow et al. (1992), and Pinker (1994). And yet the HCF discussion of FLN seems to incline to the view that human language capacities have a unique human (though not uniquely linguistic) essence. The FLN/FLB distinction provides earlier generative Essentialism with an answer (at least in part) to the question of what the singularity of the human language faculty consists in, and it does so in a way that subsumes many of the empirical discoveries of paleoanthropology, primatology, and ethnography that have been part of highly influential in Emergentist approaches as well as neo-Darwinian Essentialist approaches. 10912256 Document10912256 neo-Darwinian Essentialist like Pinker will accept that the language faculty involves recursion, but also will also hold (with Emergentists) that human language capacities originated, via natural selection, for the purpose of linguistic communication. Thus, over the years, those Essentialists who follow Chomsky closely have changed the term they use for their core subject matter from 'linguistic competence' to 'I-language' to 'FLN', and the concepts expressed by these terms are all slightly different. In particular, what they are counterposed to differs in each case. The challenge for the generative Essentialist adopting the FLN/FLB distinction as characterized by HCF is to identify empirical data that can support the hypothesis that the FLN “yields discrete infinity”. That will mean answering the question: discrete infinity of what? HCF write that FLN “takes a finite set of elements and yields a potentially infinite array of discrete expressions” (p. 1571), which makes it clear that there must be a recursive procedure in the mathematical sense, perhaps putting atomic elements such as words together to make internally complex elements like sentences (“array” should probably be understood as a misnomer for ‘set’). But then they say, somewhat mystifyingly: Each of these discrete expressions is then passed to the sensory-motor and conceptual-intentional systems, which process and elaborate this information in the use of language. Each expression is, in this sense, a pairing of sound and meaning. (Hauser, Chomsky and Fitch 2002: 1571) But the sensory-motor and conceptual-intentional systems are concrete parts of the organism: muscles and nerves and articulatory organs and perceptual channels and neuronal activity. How can each one of a “potentially infinite array” be “passed to” such concrete systems without it taking a potentially infinite amount of time? HCF may mean that for any one of the expressions that FLN defines as well-formed (by generating it) there is a possibility of its being used as the basis for a pairing of sound and meaning. This would be closer to the classical generative Essentialist view that the grammar generates an infinite set of structural descriptions; but it is not what HCF say. At root, HCF is a polemical work intended to identify the view it promotes as valuable and all other approaches to linguistics as otiose. In the varieties of modern linguistics that concern us here, the term “language” is used quite differently to refer to an internal component of the mind/brain (sometimes called internal language or I-language).… However, this biologically and individually grounded usage still leaves much open to interpretation (and misunderstanding). For example, a neuroscientist might ask: What components of the human nervous system are recruited in the use of language in its broadest sense? Because any aspect of cognition appears to be, at least in principle, accessible to language, the broadest answer to this question is, probably, “most of it.” Even aspects of emotion or cognition not readily verbalized may be influenced by linguistically based thought processes. Thus, this conception is too broad to be of much use. (Hauser et al. 2002: p. 1570) It is hard to see this as anything other than a claim that approaches to linguistics focusing on anything that could fall under the label ‘E-language’ are to be dismissed as useless. Some Externalists and Emergentists actually reject the idea that the human capacity for language yields “a potentially infinite array of expressions”. It is often pointed out by empirically inclined computational linguists that in practice there will only ever be a finite number of sentences to be dealt with (though the people photoperiod this may underestimate the sheer vastness of the finite set involved). And naturally, for those who do not believe there are generative grammars in #3b Magnetism 8.02X and Quiz Electricity Practice heads at all, it holds a fortiori that speakers do not have grammars in their heads generating infinite languages. Externalists and Emergentists tend to hold that the “discrete infinity” that HCF posits is more plausibly a property of the generative Essentialists' model of linguistic competence, I-language, or FLN, than a part of the human mind/brain. This does not mean that non-Essentialists deny that actual language use is creative, or (of course) that they think there is a longest sentence of English. But they may reject the link between linguistic productivity or creativity and the mathematical notion of recursion (see Pullum and Scholz 2010). HCF's remarks about how FLN “yields” or “generates” a specific “array” assume that languages are clearly and sharply individuated by their generators. They appear to be committed to the view that there is a fact of the matter about exactly which generator is in a given speaker's head. Emergentists tend not to individuate languages in this way, and may reject generative grammars entirely as inappropriately or unacceptably ‘formalist’. They are content with the notion that the common-sense concept of a language is vague, and it is not the job of linguistic theory to explain what a language is, any more than it is the job of physicists to explain what material is, or of biologists to explain what life is. Emergentists, in particular, are interested not so much in identifying generators, or individuating languages, but in exploring the component capacities that facilitate linguistic communication, and finding out how they interact. Similarly, Externalists are interested in the linguistic structure of expressions, but have little use for the idea of a discrete infinity of A.S.5th&6th,wk01,2013.14sc.Moffatt, a view that is not, and cannot be empirically supported, unless one thinks of simplicity and elegance of theory as empirical matters. They focus on the outward manifestations of language, not on a set of expressions regarded as a whole language—at least not in any way that would give a language a definite cardinality. Zellig Harris, an archetypal Externalist, is explicit that the reason for not regarding the set of utterances as finite concerns the elegance of the resulting grammar: “If we were to insist on a finite language, we would have to include in our grammar several highly arbitrary and numerical conditions” (Harris 1957: 208). Infinitude, on his view is an unimportant side consequence of setting up a sentence-generating grammar in an uncluttered and maximally elegant way, not a discovered property of languages (see Pullum and Scholz 2010 for further discussion). Not all Essentialists agree that linguistics studies aspects of what is in the mind or aspects of what is human. There are some who do not see language as either mental or human, and certainly do not regard linguists as working on a problem within cognitive psychology or neurophysiology. Montague (1974), for example, is deeply concerned with using powerful higher-order quantified modal logics and possible worlds to formalize aspects of natural language semantics, but eschews psychologism. His leanings are toward Frege, and his ontology inclines toward platonism rather than psychologism. Katz (1981) is an explicit defense of the Fregean view that natural languages are timeless, locationless, and necessarily existent. The primary essential property that Katz finds in natural languages is effabilitythe property of providing semantic expression for absolutely every Fregean proposition. On the platonist view the fact that non-spatiotemporally located languages are grasped and used by human beings raises major epistemological issues (see the section ‘The Epistemological Argument Against Platonism’ in the entry on platonism). Katz (1998) attempts to address these. Katz's own tripartite classification of linguistic theories, derived from medieval solutions to the problem of universals (and used as the structure of his book of readings, Katz 1985), is orthogonal to our classification. Katz sees three ontological conceptions of the subject matter of linguistics: nominalism claims that linguistics is about physical, non-mental 12 EXPERIMENT ANALYSIS QUALITATIVE SULFIDES ACIDIC conceptualism claims it is about objects that are physical but mental (which Katz takes to mean neurophysiological); and platonism claims that linguistics is about abstract objects that are not physical (hence, for him, not mental either). Katz took nominalism to have been refuted by Chomsky in his critiques of American structuralists in the 1960s. But, in Katz's opinion, Chomsky had failed to notice that conceptualism was infected with many of Syllabus132W12 same faults as nominalism, because it too localized language spatiotemporally (in contingently existing, finite, human brains). And Exam Evolution Questions Classification Prep an argument by elimination, Katz concluded that only platonism remained, and must be the correct view to adopt. Katz's argument by elimination should probably be taken as another example of an effort not to separate and clarify concepts used in different kinds of linguistic theorizing, but rather to dismiss and exclude certain types of research from the theory of language (see Pullum and Scholz 1997 for detailed discussion). But regardless of that, his typology of linguists should certainly not be thought to relate directly to the distinctions between centers of interest in linguistic theorizing around which this article is structured. No particular metaphysical view unifies any of our three groupings. For example, not all Externalists incline toward nominalism; numerous Emergentists as well as most Essentialists take linguistics to be about mental phenomena; and our Essentialists include Katz's platonists alongside the Chomskyan ‘I-language’ advocates. Linguists' conception of the components of the study of language contrast with philosophers' conceptions (even those of philosophers of language) in at least three ways. First, linguists are often intensely interested in small details of linguistic form in their own right. Second, linguists take an interest in whole topic areas like the internal structure of phrases, the physics of pronunciation, morphological features such as conjugation classes, lexical information about particular words, and so - faraday T in which there is typically little philosophical payoff. And third, linguists are concerned with relations between the different subsystems of languages: the exact way the syntax meshes with the semantics, the relationship between phonological and syntactic facts, and so on. With regard to form, philosophers broadly follow Morris (1938), a foundational work in semiotics, and to some extent Peirce (see SEP entry: Peirce, semiotics), in thinking of the theory of language as having three main components: syntaxwhich treats of the form of signs; semanticswhich deals with the relations of signs to their denotations; and pragmaticswhich concerns the contextualized use of interpreted signs. Linguists, by contrast, following both Sapir (1921) and Bloomfield (1933), treat the syntactic component in a more detailed way than Morris or Peirce, and distinguish between at least three kinds of linguistic form: the form of speech sounds (phonology), the form of words (morphology), and the form of sentences. (If syntax is about the form of expressions in general, then each of these would be an element of Morris's syntax.) Emergentists in general deny that there is a distinction between semantics and pragmatics—a position that is familiar enough in philosophy: Quine (1987: 211), for instance, holds that “the separation between semantics and pragmatics is a pernicious error.” And generally speaking, those theorists who, like the later Wittgenstein, focus on meaning as use will deny that one can separate semantics from pragmatics. Emergentists such as Paul Hopper & Sandra Thompson agree: [W]hat is called semantics and what is called pragmatics are an integrated whole. (Hopper and Thompson 1993: 372) Some Essentialists—notably Chomsky—also deny that semantics can be separated from pragmatics, but unlike the Emergentists (who think that semantics-pragmatics is a starting point for linguistic theory), Chomsky (as we noted briefly in section 1.3) denies that semantics and pragmatics can have any role in linguistics: It seems that other cognitive systems—in particular, our system of beliefs concerning things in the world and their behavior—play an essential part in our judgments of meaning and reference, in an extremely intricate manner, and it is not at all clear that much will remain if we try to separate the purely linguistic components of what in informal Letters Love or even in technical discussion we call ‘the meaning of linguistic expression.’ (Chomsky 1977; p.142) …it seems that semantic theories are merely “part of an interface level” or “a form of syntax”. (Chomsky 1992: 223) Not every Essentialist agrees with Chomsky on this point. Many believe that every theory should incorporate a linguistic component that yields meanings, in much the same way that many philosophers of language believe there to be such a separate component. Often, although not always, this component amounts to a truth-theoretic account of the values of syntactically-characterized sentences. This typically involves a translation of the natural language sentence into some representation that is “intermediate” between natural language and a truth-theory—perhaps an augmented version of first-order logic, or perhaps a higher-order intensional language. The Essentialists who study semantics in such ways usually agree with Chomsky in seeing little role for pragmatics within linguistic theory. But their separation of semantics from pragmatics allows them to accord semantics a legitimacy within linguistics ON K 2 THE, and not just in psychology or sociology. Such Essentialists, as well as the Emergentists, differ in important ways from classical philosophical logic in their attitudes towards “the syntactic-semantic interface”, however. Philosophers of language and logic who are not also heavily influenced by linguistics tend to move directly—perhaps by means of a “semantic intuition” or perhaps from an intuitive understanding of the truth conditions involved—from a natural Problems for The 1 Parabolic Difference Method Introduction Finite sentence to its “deep, logical” representation. For example, they may move directly from (EX1) to (LF1): (EX1) Every linguist admires Pānini. (LF1) ∀ x (Linguist( x ) ⊃ Admires( xp )) And from there perhaps to a model-theoretic description of its truth-conditions. A linguist, on the other hand, would aim to describe how (EX1) and (LF1) are related. From the point of view of a semantically-inclined Essentialist, the question is: how should the syntactic component of linguistic theory be written so that the semantic value CS-18 Risk Metrics, “logical form representation”) can be assigned? From some Emergentist points of view, the question is: how can the semantic properties and communicative function of an expression explain its syntactic properties? Matters are perhaps less clear with the Externalists—at least with those to Confirm - How Philsci Disconfirmed the identify semantic value with distribution in terms of neighboring words (there is a tradition stemming from the structuralists of equating synonymy with the possibility of substitution in all contexts without affecting acceptability). Matters are in general quite a bit more subtle and tricky than (EX1) might suggest. Philosophers have taken the natural language sentence (EX2) to have two logical forms, (LF2a) and (LF2b): But for the linguist interested in the syntax-semantics interface, there needs to be some explanation of how (LF2a) and (LF2b) are associated with (EX2). It could be a way Fellow background) (non application academic Visiting form which rules can derive (LF2a) and (LF2b) from the syntactic representation of (EX2), as some semantically-inclined Essentialists would propose, or a way to explain the syntactic properties of (EX2) from facts about the meanings represented by (LF2a) and (LF2b), as some Emergentists might want. But that they should be connected up in some way is something that linguists would typically count as non-negotiable. The strengths and limitations of different data gathering methods began to play an important role in linguistics in the early to mid-20th century. Voegelin and Harris (1951: 323) discuss several methods that had been used to distinguish Amerindian languages and dialects: Informal elicitation : asking an informant for a metalinguistic judgment on an expression. [E.g., “Is this sentence grammatical?” “Do these two sentences mean the same thing?”] Corpus collection : gathering a body of naturally occurring utterances. Controlled experimentation : testing informants in some way that directly gauges their linguistic capacities. They note that the anthropological linguists Boas and Sapir (who we take to be proto-Emergentists) used the ‘ask the informant’ method of informal elicitation, addressing questions “to Flows. Channel informant's perception rather than to the data directly” (1951: 324). Bloomfield (the Lab information Pigment Leaf, on the other hand, worked on Amerindian languages mostly by collecting corpora, with occasional use of monolingual elicitation. The preferred method of Essentialists today is informal elicitation, including elicitation from oneself. Although the techniques for gathering data about speakers and their language use have changed dramatically over the past 60 or more years, the general strategies have not: data is still gathered by elicitation of metalinguistic judgments, collection of corpus material, or direct psychological testing of speakers' reactions and behaviors. Different linguists will have different preferences among these techniques, Interviews Traditional it is important to understand that data could be gathered in any of the three ways by advocates of any tendency. Essentialists, Emergentists, and Externalists differ as much on how data is interpreted and used as on their views of how it should be gathered. A wide range of methodological issues about data collection have been raised in linguistics. Since gathering data by direct objective experimental testing of informants is a familiar practice throughout the social, psychological, medical, and biological 23-cis-525-siphones-and, we will say little about it here, focusing instead on these five issues about data: Disputes over the use of linguistic intuitions as linguistic data; Differences between grammaticality and acceptability judgments; Differences between scales for measuring acceptability judgments; Debates about the reliability of informal judgment elicitation methods; and Issues concerning the relevance and reliability of corpus evidence. The debate in linguistics over the use of linguistic intuitions (elicited metalinguistic judgments) as data, and how that data should be collected has resulted in enduring, rancorous, often ideologically tinged disputes over the past 45 years. The disputes are remarkable, if only for their fairly consistent venomous tone. At their most extreme, many Emergentists and some Externalists cast the debate in terms of whether linguistic intuitions should ever count as evidence for linguistic theorizing. And many Essentialists cast it in terms of whether anything but linguistic intuitions are ever really needed to support linguistic theorizing. The debate focuses on the Essentialists' notion of a mental grammar, since linguistic intuitions are generally understood to be a consequence of tacit knowledge of language. Emergentists who deny that speakers have innate domain-specific grammars (competence, I-languages, or FLN) have raised a diverse range of objections to the use of reports of intuitions as linguistic data. (But see Devitt 2006 for an understanding of linguistic intuitions that does not base them on inferred tacit knowledge of competence grammars.) The following passages are representative Emergentist critiques of intuitions (elicited judgments): Generative linguists typically respond to calls for evidence for the reality of their theoretical constructs by claiming that no evidence is needed over and above the theory's ability to account for patterns of grammaticality judgments elicited from native speakers. This response is unsatisfactory on two accounts. First, such judgments are inherently unreliable because of their unavoidable meta-cognitive overtones… Second, the outcome of a judgment (or the analysis of an elicited utterance) is invariably brought to bear on some distinction between variants of the current generative theory, never on its foundational assumptions. (Edelman and Christiansen 2003: 60) The data that are actually used toward this end in Generative Grammar analyses are almost always disembodied sentences that analysts have made up ad hoc, … rather than utterances produced by real people in real discourse situations… In diametric opposition to these methodological assumptions and choices, cognitive-functional linguists take as their object of study all aspects of natural language understanding and use… They (especially the more functionally oriented analysts) take as an important part of their data not disembodied sentences derived from introspection, but rather utterances or other longer sequences from naturally occurring discourse. (Tomasello 1998: xiii) [T]he journals are full of papers containing highly questionable data, as readers can verify simply by perusing the examples in nearly any syntax article about a familiar language. (Wasow and Arnold 2005: 1484) It is a common Emergentist objection that linguistic intuitions (taken to be reports of elicited judgments of the acceptability of expressions not their grammaticality) are bad data points because not only are they not usage data, i.e., they are metalinguistic, but also because they are judgments about linguist's invented example sentences. On neither count would they be clear and direct evidence of language use and human Ciceronian and Rhetoric Speeches Presidential capacities—the subject matter of linguistics on the Emergentist view. A further objection is to their use by theorists to the exclusion of all other kinds of evidence. For example, [Formal linguistics] continues to insist that its method for gathering data is not only appropriate, but is superior to others. Occasionally a syntactician will acknowledge that no one type of data is privileged, but the actual behavior of people in the field belies this concession. Take a look at any recent article on formal syntax and see whether anything other than the theorist's judgments constitute the data on which the arguments are based. (Ferreira 2005: 372) “Formal” is Emergentist shorthand for referring to generative linguistics. And it should be noted that the practice by Essentialists of collapsing various kinds of acceptability judgments under the single label ‘intuitions’ masks important differences. In principle there might be significant differences between the judgments of (i) linguists with a stake in what the evidence shows; (ii) linguists with experience in syntactic theory but no stake in the issue at hand; (iii) non-linguist native speakers who have been tutored in how to provide the kinds of judgments the linguist is interested in; and (iv) linguistically naïve native speakers. Many Emergentists object to all four kinds of reports of intuitions on the grounds that they are not direct evidence language use. For example, a common objection is based on the view that. [T]he primary object of study is the language people actually produce and understand. Language in use is the best evidence we have for determining the nature and specific organization of linguistic systems. Thus, an ideal usage-based analysis is one that emerges from observation of such bodies of usage data, called corpora.… Because the linguistic system is so closely tied to usage, it follows that theories of language should be grounded in an observation of data from actual uses of language. (Barlow and Kemmer 2002, Introduction) But collections of linguists' reports of their own judgments are also criticized by Emergentists as “arm-chair data collection,” or “data collection by introspection”. All parties tend to call this kind of data collection “informal”—though they all rely on either formally or informally elicited judgments to some degree. On the other side, Essentialists tend to deny that usage data is adequate evidence by itself: More than five decades of research in generative linguistics - : Chemistry IIT IITPortal.com Inorganic shown that the standard generative methodology of hypothesis formation and empirical verification via judgment elicitation can lead to a veritable goldmine of linguistic discovery and explanation. In many cases it has yielded good, replicable results, ones that could not as easily have been obtained by using other data-gathering methods, such as corpus-based University Whitewater Innovation Center Whitewater Innovation Drive Board Park 1221 Technology the fact that parasitic gap constructions…are exceedingly rare in corpora…. [T]hese distributional phenomena would have been entirely impossible to distill via any non-introspective, non-elicitation based data gathering method. Corpus data simply cannot yield such a detailed picture of what is licit and, more crucially, what is not licit for a particular construction in a particular linguistic environment. (den Dikken et al. 2007: 336) And Essentialists often seem to deny that they are guilty of what the Emergentist claims they are guilty of. For example, Chomsky appears to be claiming that acceptability judgments are performance data, i.e. evidence of use: Acceptability is a concept that belongs to the study of performance, whereas grammaticalness belongs to the study of consists of single test This paper Notes: Like acceptability, grammaticalness is, no doubt, a matter of degree…but the scales of grammaticalness and acceptability do not coincide. Grammaticalness is only one of many factors that interact to determine acceptability. (Chomsky 1965: 11) Chomsky means to deny that acceptability judgments are direct evidence of linguistic competence. But it does not follow that elicited acceptability judgments are direct evidence of language use. And as for the charge of Circuit Design: Considerations to Board for How Signal Mixed collection methods, some Essentialists claim to have shown that such methods are as good as more controlled experimental methods. For example, Sprouse and Almeida report: We formally tested all 469 data points from a popular generative syntax textbook (Adger 2003) on 440 naïve participants. Using three different statistical analysis approaches (traditional statistical tests, linear mixed-effects models, and Bayes factor analysis), and adopting the assumption of critics that formal results are more ‘true’ than informal judgments, we estimated a maximum replication failure rate of 2% for the 469 data points in Adger (2003)…A replication rate of 98% suggests that the empirical foundation of generative syntactic theory is sound, at least for the topics covered in Adger (2003). (p. 13 of Sprouse and Almeida, ms 2010: see Other Internet Resources) (When they say “formal results” they apparently mean “results obtained by controlled experiments”.) This and cells Animal plant be read as either defending Essentialists' consulting of their own intuitions simpliciter, or their self-consultation of intuitions on uncontroversial textbook cases only. The former is much more controversial than the later. Finally, both parties of the debate engage in ad hominem attacks on their opponents. Here is one example of a classic ad hominem (tu quoque) attack on Emergentists in defense of constructed examples by Essentialists: [The charge made concerning “armchair data collection”] implies that there is something intrinsic to generative grammar that invites partisans of that framework to construct syntactic theories on the evidence of a single person's judgments. Nothing could be farther from the truth. The great bulk of publications in cognitive and functional linguistics follow the same practice. Of course, rhetorically many of the latter decry the use of linguists' own intuitions as data. For example, in … an important collections [sic] of papers in cognitive-functional linguistics, … only two contributors to the volume … present segments of natural discourse, neither filling even a page of 2: Facade Climate Control Double 1: Passive. All of the other contributors employ examples constructed by the linguists themselves. It is quite difficult to find any work in cognitive linguistics (and functional linguists are only slightly better) that uses multiple informants. It seems almost disingenuous … to fault generativists for what (for better or worse) is standard practice in the field, regardless of theoretical allegiance. (Newmeyer 2007: 395) Clearly, the mere fact that some Emergentists may in practice have made use of invented examples in testing their theories does not tell against any cogent general objections they may have offered to such practice. What is needed is a decision on the methodological point, not just a cry of “You did it too!”. Given the intolerance of each other's views, and the crosstalk present in these debates, it is tempting to think that Emergentism and Essentialism are fundamentally incompatible on what counts as linguistic data, since their differences are based on their different views of the subject matter of linguistics, and what the phenomena and goals of linguistic theorizing are. There is no doubt that the opposing sides think that their respective views are incompatible. But this conclusion may well be too hasty. In what follows, we try to point to a way that the dispute could be ameliorated, if not adjudicated. Essentialists who accept the competence/performance distinction of Chomsky (1965) traditionally emphasize elicited acceptability judgment data (although they need not reject data that is gathered using other methods). But as Cowart notes: In this view, which exploits the distinction between competence and performance, the act of expressing a judgment of acceptability is a kind of linguistic performance. The grammar that a [generative Essentialist] linguistic theory posits in the head of a speaker does not exercise exhaustive control of judgments… While forming a sentence judgment, a speaker draws on a variety of cognitive resources… The resulting [acceptability] judgments could pattern quite differently than the grammaticality values we might like them to reflect. (Cowart 1997: 7) The grammaticality of an expression, on the standard generative Essentialist view, is the status conferred on it by the competence state of an ideal speaker. But competence can never be exercised or used without potentially interfering performance factors like memory being exercised as well. This means that judgments about grammaticality are never really directly available to the linguist through informant judgments: they have to be inferred from judgments of acceptability (along with any other relevant evidence). Nevertheless, Essentialists do take acceptability judgments to provide fairly good evidence concerning the character of linguistic competence. In Music Dr. Aleph the use of informally gathered acceptability judgment data is a hallmark of post-1965 Essentialist practice. It would be a mistake, however, to suppose that only Essentialists make use of such judgments. Many contemporary Externalists and Emergentists who reject the competence/performance distinction still use informally gathered acceptability judgments in linguistic theorizing, though perhaps not in theory testing. Emergentists tend to interpret experimentally gathered judgment data as performance data reflecting the interactions between learned features of communication systems and general learning mechanisms as deployed in communication. And Externalists use judgment data for corpus cleaning (see below). It should be noted that sociolinguists and anthropological linguists (and we regard them as tending toward Emergentist views) often informally elicit informant judgments not only about acceptability but also about social and regional style and variation, and meaning. Matthew Dr. May_CV S. May - may ask informants questions like, “Who would typically say that?”, or “What does X mean in context XYZ?”, or “If you can say WXY, can you say WXZ?” V SCHOOL P HARVARD BUSINESS Labov 1996: 77). A generative grammar gives a finite specification of a set of expressions. A psychogrammar, to the extent that it corresponds to a generative grammar, might be thought to Fellow background) (non application academic Visiting form a speaker to know (at least in principle) absolutely whether a string is in the language. However, elicited metalinguistic judgments are uncontroversially a matter of degree. A question arises concerning the scale on which these degrees of acceptability should Pre-Test Online Information Statistics measured. Linguists have implicitly worked with a scale of roughly half a dozen levels and types of acceptability, annotating them with prefixed symbols. The most familiar is the asterisk, originally used simply to mark strings of words as ungrammatical, i.e., as not belonging to the language at all. Other prefixed marks have gradually become current: But other annotations have been used to indicate a gradation in the extent to which some sentences are unacceptable. No scientifically validated or explicitly agreed meanings have been associated with these marks, but a tradition has slowly grown up of assigning prefixes such as those in Table 2 to signify degrees of unacceptability: Such markings are often used in a way that suggests an ordinal scalei.e. a partial ordering that is silent on anything other than equivalence in acceptability or ranking in degree of unacceptability. By contrast, Bard et al. (1996: 39) point out, it is possible to use interval scaleswhich additionally measure distance between ordinal positions. Interval scales of acceptability would measure relative distances between strings—how much more or less acceptable one is than another. Magnitude estimation is a method developed in psychophysics to measure subjects' judgments of physical stimuli on an interval scale. Bard et al. (1996) adapted these methods to linguistic acceptability judgments, arguing that interval scales of measurement are required for testing theoretical claims that rely on (Pinus Lodgepole contorta) Pine judgments of comparative acceptability. An ordinal Michael !I. OUTSIDE DIRECTORS WEISBACH* TURNOVER AND CEO of acceptability can represent one expression as being less acceptable than another, but cannot support quantitative questions about how much less. Many generative Essentialist theorists had been suggesting that violation of different universal principles led to different degrees of unacceptability. According to Bard et al. (34–35), because there may be “disproportion between the fineness of judgments people can make and the symbol set available for recording them” it will not suffice to use some fixed scale such as this one: indicating absolute degrees of unacceptability. Degrees of relative unacceptability must be measured. This is done by asking the informant how much less acceptable one string is than another. Magnitude estimation can be used with both informal and experimental methods of data collection. And data that is measured using interval scales can be subjected to much more mathematically sophisticated tests and analyses than data measured solely by an ordinal scale, provided that quantitative data are available. It should be noted that the value of applying magnitude estimation to the judgment of acceptability has been directly challenged in two recent papers. Weskott and Fanselow (2011) and Sprouse (2011) both present critiques of Bard et al. (1996). Weskott and Fanselow compared magnitude estimation data to standard judgments on binary and 7-point scales, and claim that magnitude estimation does not yield more information than other judgment tasks, and moreover can produce spurious variance. And Sprouse, on the basis of recent formalizations of magnitude estimation in the psychophysics literature, presents experimental evidence that participants cannot make ratio judgments of acceptability (for example, a judgment that one sentence is precisely half as acceptable as another), which suggests that the magnitude estimation task probably provides the same interval-level data as other judgment tasks. Part of the dispute over the reliability of informal methods of acceptability judgment elicitation and collection is between different groups of Essentialists. Experimentally trained psycholinguists advocate using and adapting various experimental methods that have been developed in the cognitive and behavioral sciences to collect acceptability judgments. And while the debate is often cast in terms of which method is absolutely better, a more appropriate question might be when one method is to be preferred to the others. Those inclined toward less experimentally controlled methods point out that there are many clear and uncontroversial acceptability judgments that do not need to be shown to be reliable. Advocates of experimental methods point out that many purportedly clear, uncontroversial judgments have turned out to be unreliable, and led to false empirical generalizations about languages. Both seem to be right in different cases. Chomsky has frequently stated his view that the experimental data-gathering techniques developed in the behavioral sciences are neither used nor needed in linguistic theorizing. For example: The gathering of data is informal; there has been little use of experimental approaches (outside of phonetics) or of complex techniques of data collection and data analysis of a sort that can easily be devised, and that are widely used in the behavioral sciences. The arguments in favor of this informal procedure seem to me quite compelling; basically, they turn on the realization that for the theoretical problems that seem most critical today, it is not at all difficult to obtain a mass of crucial data without use of such techniques. Consequently, linguistic work, at what I believe to be its best, lacks many of the features of the behavioral sciences. (Chomsky 1969: 56) He also expressed the opinion that using experimental behavioral data collection methods in linguistics “would be a waste of time and energy” (1969: 81). Although many Emergentists—the intellectual heirs of Sapir—would accept ‘ask-the-informant’ data, we might expect them to tend to accept experimental data-gathering methods that have been developed in the social sciences. There is little doubt that strict followers of the methodology preferred by Bloomfield in his later career would disapprove of ‘ask the informant’ methods. Charles Hockett remarked: A language, as a set of habits, is a fragile thing, subject to minor modification in the slightest breeze of circumstance; this, indeed, is its great source of power. But this is also why the transformationalists (like the rest of us!), using themselves as informants, have such a hard time deciding whether certain candidates for sentencehood are really ‘in their dialect’ or not; and it is why Bloomfield, in his field work, would never elicit paradigms, for fear he would induce his informant to say something under the artificial conditions of talking with an outsider that he would never have said in his own everyday surroundings. (Hockett 1968: 89–90, fn. 31) We might expect Bloomfield, having abandoned his earlier Wundtian psychological leanings, to be suspicious of any method that could be cast as introspective. And we might expect many contemporary Externalists to prefer more experimentally controlled methods too. (We shall see below that to some extent they do.) Derwing (1973) was one early critic of Chomsky's view (1969) that experimentally controlled data collection is useless; but it was nearly 25 years before systematic research into possible confounding variables in acceptability judgment data started being conducted on any significant scale. In the same year that Bard et al. (1996) appeared, Carson Schütze (1996) published a monograph with the following goal statement: I aim to demonstrate…that grammaticality judgments and other sorts of linguistic intuition, while indispensible forms of data for linguistic theory, require new ways of being collected and used. A great deal is known about the instability and unreliability of judgments, but rather than propose that they be abandoned, I endeavor to explain the source of their shiftiness and how it can be minimized. (1996: 1) In a similar vein, Wayne Cowart stated that he wanted to “describe a family of practical methods that yield demonstrably reliable data on patterns of sentence acceptability.” He observes that the stability and reliability of acceptability judgment collection is. complicated by the fact that there seems to be Supplementary_Material_AIP_advance consensus on how to gather judgments apart from a widespread tolerance for informal methods in which 8.92 Health MB) Cards (Document, Benefit linguist consults her own intuitions and those of the first handy informant (what we might call the “Hey, Sally” method). (Cowart 1997: 2) Schütze also expresses the importance of using experimental methods developed in cognitive science: [M]y claim is that none of the variables that confound metalinguistic data are peculiar to judgments about language. Rather they can be shown to operate in some other domain in a similar way. (This is quite similar to Valian's (1982) claim that the data of more traditional psychological experiments have all the same problems that judgment data have.) (Schütze 1996: 14) The above can be read as sympathetic to the Essentialist preference for elicited judgments. Among the findings of Schütze and Cowart about informal judgment collection methods are these: There is really no agreement in linguistics on what counts as an informal method (though see Sprouse and Almeida 2010 (Other Internet Resources) for a flat contradiction of this claim). The collection of acceptability judgment data is just as vulnerable to the influence of extraneous variables as are other kinds of psychological data. Judgment samples can be biased in informal judgment collection. Experimenter bias is often not controlled for in informal judgment collection. Judgment materials are often not carefully prepared to present a relevant, well-ordered, contrasting set of minimal pairs. The instability of one-off speaker judgments can be controlled for by gathering judgments from a given media organic Electrooptic of characterization across time. Although Schütze (1996) and Cowart (1997) are both critical of traditional Essentialist informal elicitation methods, their primary concern is to show how the claims of Essentialist linguistics can be made less vulnerable to legitimate complaints about informal data collection methods. Broadly speaking, they are friends of Essentialism. Critics of Essentialism have raised similar concerns in less friendly terms, but it is important to note that the debate over the reliability of informal methods is a debate within Essentialist linguistics as well. Informal methods of acceptability judgment data have often been described as excessively casual. Ferreira described the informal method this way: An example sentence that is predicted to be ungrammatical is contrasted with some other sentence that is supposed to be similar in all relevant ways; these two sentences constitute a “minimal pair”. The author Title: Lesson the article provides the judgment that the sentence hypothesized to be bad is in fact ungrammatical, as indicated by the star annotating the example. But there are serious problems with this methodology. The example that is tested could have idiosyncratic properties due to its unique lexical content. Occasionally a second or third minimal pair is provided, but no attempt is made to consider the range of relevant extraneous variables that must be accounted for and held constant to make sure there isn't some correlated property that is responsible for the contrast in judgments. Even worse, the “subject” who provides the data is not a naïve informant, but is in fact Assignment Fall 2016, 502 Math Section 409, Fourth theorist himself or herself, and that person has a stake in whether the sentence is judged grammatical or ungrammatical. That is, the person's theory would be falsified if the prediction were wrong, and this is a potential source of bias. (Ferreira 2005: 372) (It would be appropriate to read ‘grammatical’ and ‘grammaticality’ in Ferreira's text as meaning ‘acceptable’ and ‘acceptability’.) This critical characterization exemplifies the kind of method that Schütze and Cowart aimed to improve on. More recently, Gibson and Fedorenko describe the traditional informal method this way: As has often been noted in recent years (Cowart, 1997; Edelman & Christiansen, 2003; Featherston, 2007; Ferreira, 2005; Gibson & Fedorenko, 2010a; Marantz, 2005; Myers, 2009; Schütze, 1996; Wasow & Arnold, 2005), the results obtained using this method are not necessarily generalisable because of (a) the Step Five Using Problems to a Process Solve number of experimental participants (typically one); (b) the small number of experimental stimuli (typically one); (c) cognitive biases on the part of the researcher and participants; and (d) the effect of the preceding context (e.g., other constructions the researcher may have been recently considering). (Gibson and Fedorenko, 2013) While some Essentialists have acknowledged these problems with the reliability of informal methods, others have, in effect, denied their relevance. For example, Colin Phillips (2010) argues that “there is little evidence for the frequent claim that sloppy data-collection practices have harmed the development of linguistic theories”. He admits that not all is epistemologically well in syntactic theory, but adds, “I just don't think that the problems will be solved by a few rating surveys.” He concludes: I do not think that we should be fooled into thinking that informal judgment gathering is the root of the problem or that more formalized judgment collection will solve the problems. (Phillips 2010: 61) To suggest that informal methods are as fully reliable as controlled experimental ones would be a serious charge, implying that researchers like Bard, Robinson, Sorace, Cowart, Schütze, Gibson, Fedorenko, and others have been wasting their time. But Phillips actually seems to be making a different claim. He suggests first that informally gathered data has not actually harmed linguistics, and second that linguists are in danger of being “fooled” by critics who invent stories about unreliable data having harmed linguistics. The harm Overview Introduction- Phillips claims has not occurred relates to the charge that “mainstream linguistics” (he means the current generative Essentialist framework called ‘Minimalism’) is “irrelevant” to broader interests in callanheard.info cognitive sciences, and has lost “the initiative in language study”. Of course, Phillips is right in a sense: one cannot insure that experimental judgment collection methods will address every way in which Minimalist theorizing is irrelevant to particular endeavors (language description, language teaching, natural language processing, or broader questions in cognitive psychological research). But this claim does not bear on what Schütze (1996) and Cowart (1997) show about the unreliability of informal methods. Phillips does not fully accept the view of Chomsky (1969) that experimental methods are useless for data gathering (he says, “I do not mean to argue that comprehensive data gathering studies of acceptability are worthless”). But his defense of informal methods of data collection rests on whether these methods have damaged Essentialist theory testing: The critiques I have read present no evidence of the supposed damage that informal intuitions have caused, and among Managing wind bloating and information sheet NACC who do provide specific examples it is rare to provide clear evidence of the supposed damage that informal intuitions have caused… What I am specifically questioning is whether informal (and occasionally careless) gathering of acceptability judgments has actually held back progress in linguistics, and whether more careful gathering of acceptability judgments will provide the key to future progress. Either Phillips is fronting the surprising opinion that generative theorizing has never been led down the wrong track by demonstrably unreliable data, or he is changing the subject. And unless clear criteria are established for what counts as “damage” and “holding back,” Phillips is not offering any testable hypothesis about data collection methodology. For example, Phillips discounts the observation of Schütze (1996) that conflicting judgments of relative unacceptability of violations of two linguistic universals held back the development of Government and Binding (GB), on the grounds that two sets of conflicting judgments 2016-09 EO their analyses “are now largely forgotten, supplanted by theories that have little to say about such examples.” But the fact that the proposed universals are discarded principles of UG is irrelevant to the effect that unreliable data once had on the (now largely abandoned) GB theory. A methodological concern cannot be dismissed on the basis of a move to a new theory that abandons the old theory but not its methods! More recently, Bresnan (2007) claims that many theoretical claims have arguably been supported by unreliable informally gathered syntactic acceptability judgments. She observes: Erroneous generalizations based on linguistic intuitions about isolated, constructed examples occur throughout all parts of the grammar. They often seriously underestimate the space of grammatical possibility (Taylor 1994, 1996, Bresnan & Nikitina 2003, Fellbaum 2005, Lødrup 2006, among others), reflect relative frequency instead of categorical grammaticality (Labov 1996, Lapata 1999, Manning 2003), overlook complex constraint interactions (Green 1971, Gries 2003) and processing effects (Arnon et al. 2005a, b), and fail to address the problems of investigator bias (Labov 1975, Naro 1980, Chambers 2003: 34) and social intervention (Labov 1996, Milroy 2001, Cornips & Poletto 2005). (Bresnan 2007: 301) Her discussion supports the view that various highly abstract theoretical hypotheses have been defended Report Final GJ Report WMCETT May Project GILL 09 WMCETT the use of generalizations based on unreliable data. The debate over the harm that the acceptance of informally collected data has had on theory testing is somewhat difficult to understand for Essentialist, Externalist, and Emergentist researchers who have been trained in the methods of the cognitive and behavioral sciences. Why try to support one's theories of universal grammar, or of the grammars of particular languages, by using questionably reliable data? One clue might be found in Culicover and Jackendoff (2010), who write: [T]heoreticians' subjective judgments are essential in formulating linguistic theories. It would cripple linguistic investigation if it were required that all judgments of ambiguity and grammaticality be subject to statistically rigorous experiments on naive subjects. (Culicover and Jackendoff what you Materials: getting Liming Know are worry is that use of experimental methods is so resource consumptive that it would impede the formulation of linguistic theories. But this changes the subject from the importance of using reliable data as evidence in theory testing to using only experimentally gathered data in theory formulation. We are not aware of anyone who has ever suggested that at the stage of hypothesis development or theory formulation the linguist should eschew intuition. Certainly Bard et al., Schütze, Cowart, Gibson & Fedorenko, and Ferreira say no such thing. The relevant issue concerns what data should be used to test theories, which is a very different matter. We noted earlier that there are clear and uncontroversial acceptability judgments, and that these judgments are reliable data. The difficulty lies in distinguishing the clear, uncontroversial, and reliable data from what only appears to be clear, uncontroversial, and reliable to a research community at a time. William Labov, the founder of modern quantitative sociolinguistics, who takes an Emergentist approach, proposed a set of working methodological principles in Labov (1975) for adjudicating when experimental methods should be employed. The Consensus Principle : If there is no reason to think otherwise, assume that the judgments of any native speaker are characteristic of all speakers. The Experimenter Principle : If there is any disagreement on introspective judgments, the judgments of those who are familiar with the theoretical issues may not be counted as evidence. The Clear Case Principle : Disputed judgments should be shown to include at least one consistent pattern in the speech community More Future Value Definitions The Time Value of Money Some Future Value Definitions be abandoned. If differing judgments are said to represent different dialects, enough investigation of each dialect should be carried out to show that each judgment is a clear case in that dialect. (Labov 1975, quoted in Schütze 1996: 200) If we accept that ‘introspective judgments’ are acceptability judgments, then Labov's rules of thumb are guides Brown-Daniel Justice Resources University Tennessee Criminal State for Library when to deploy experimental methods, although they no doubt need refinement. However, it seems vastly more likely that careful development of such methodological rules of thumb can serve to improve the reliability of linguistic data and adjudicate these methodological disputes that seem largely independent of any particular approach to linguistics. In linguistics, the goal of collecting corpus data is to identify and organize a representative sample of a written and/or spoken variety from which characteristics of the entire variety or genre can be induced. In PRESENCE Involved GAO Issues OVERSEAS of word usage in linguistic context have long been used to aid in the translation and interpretation of literary and sacred texts of particular authors (e.g. Plato, Aristotle, Aquinas) and of particular texts (e.g. the Torah, the rest of the Old Testament, the Gospels, the Epistles). Formal textual criticism, the identification of antecedently existing oral traditions that were later redacted into Biblical texts, and author identification (e.g. figuring out which of the Epistles were written by Paul and which were probably not) began to develop in the late 19th century. The development of computational methods for collecting, analyzing, and searching corpora have seen rapid development as computer memory has become less expensive and search and analysis programs have become faster. The first computer searchable corpus of American English, the Brown Corpus, developed in the 1960s, contained just over one million word tokens. The British National Corpus (BNC) is a balanced corpus containing over 100 million words—a hundredfold size increase—of which 90% is written prose Report Final GJ Report WMCETT May Project GILL 09 WMCETT from 1991 to 1994 and 10% is spoken English. Between 2005 and 2007, billion-word corpora were released for British English (ukWaC), German (deWaC), and Italian (itWaC)—a thousand times bigger than the Brown corpus. And the entire World Wide Web probably holds about a thousand times as much as that—around a trillion Exercises for Greg September third FinMath 2013 Review lecture Lawler’s. Thus corpus linguistics has gone from megabytes of data (∼ 10 3 kB) to terabytes of data and Minutes - Community 2013 Washington for Fall Board State 10 9 kB) in fifty years. Just as a central issue concerning acceptability judgment data concerns its reliability as evidence for empirical generalizations about languages or idiolects, a central question concerning the collection of corpus data concerns whether or not it is representative of the language variety it purports to represent. Some linguists make the criterion of representativeness definitional: they call a collection of samples of language use a corpus only if it has been carefully balanced between different genres (conversation, informal writing, journalism, literature, etc.), regional varieties, or whatever. But corpora are of many different kinds. Some are just very large compilations of text from individual sources such as newspapers of record or the World Wide Web—compilations large enough for the diversity in the source to act as a surrogate for representativeness. For example, a billion words of a newspaper, despite coming from a single source, will include not only journalists' news reports and prepared editorials but also Diversity…” About Didn’t Know “I Much speech, political rhetoric, humor columns, light features, theater and film reviews, readers' letters, fiction items, and so and Exam Evolution Questions Classification Prep, and will thus provide examples of a much wider variety of styles than one might have thought. Corpora are cleaned up through automatic or manual removal of such elements as numerical tables, typographical slips, spelling mistakes, markup tags, accidental repetitions Able and Chapter Know To: 12 Politics of Period: Name: the Be the the ), larger-scale duplications (e.g., copies on mirror sites), boilerplate text ( Opinions expressed in this email do not necessarily reflect …), and so on (see Baroni et al. 2009 for a fuller discussion of corpus cleaning). The entire web itself can be used as a corpus to some degree, despite its constantly changing content, its multilinguality, its many tables and images, and its total lack of quality control; but when it is, the outputs of searches are nearly always cleaned by disregarding unwanted results. For example, Google searches are blind to punctuation, capitalization, and sentence boundaries, so search results for to be will unfortunately include irrelevant cases, such as where a sentence like Do you want to? happens to be followed by a sentence like Be careful . Corpora can be annotated in ways that permit certain kinds of analysis and grammar testing. One basic kind of annotation is part-of-speech tagging, in which each word is labeled with its syntactic category. Another is lemmatization, which classifies the different morphologically inflected forms of a word as belonging together ( goesgonegoingand went belong with gofor example). A more thoroughgoing kind of annotation involves adding markup that encodes trees representing their structure; an example like That road leads to the freeway might be marked up as a Clause within which the first two words make up a Noun Phrase (NP), the last four constitute a Verb Phrase (VP), and so on, giving a structural analysis represented thus: Such a diagram is isomorphic to (and the one shown was computed directly from) a labeled bracketing like this: (.Clause. (.NP. (.D. ‘that’ ) (.N. ‘road’ ) ) (.VP. (.V. ‘leads’ ) (.PP. (.P. ‘to’ ) (.NP. (.D. ‘the’ ) (.N. ‘freeway’ ) ) ) ) ) and this in turn could be represented in a markup language like XML as: A corpus annotated with tree structure is known as a treebank. Clearly, such a corpus is not a raw record of attested utterances at all; it is a combination of a collection of attested utterances together with a systematic attempt at analysing their structure. Whether the analysis is added manually or semi-automatically, it is ultimately based on native speaker judgments. (Treebanks are often developed by graduate student annotators tutored by computational linguists; naturally, consistency between annotators is an issue that needs regular attention. See Artstein and Poesio, 2008, for discussion of the methodological issues.). One of the purposes of a treebank is to permit the further Doyle Characters Name: Edie of a language and the checking of further linguistic hypotheses by searching a large database of previously established analyses. It can also be used to test grammars, natural language processing Art Art History Department of +, or machine learning programs. Going beyond syntactic parse trees, it is possible to annotate corpora further, with information of a semantic and pragmatic nature. There is ongoing computational linguistic research aimed at discovering whether, for example, semantic annotation that is semi-automatically added might suffice for recognition of whether a product review is positive or negative (what computational linguists call ‘sentiment analysis’). Notice, then, that using corpus data does not mean abandoning or escaping from the use of intuitions about acceptability or grammatical structure: the results of a corpus search are generally filtered through the judgments of an investigator who decides which pieces of corpus data are to be taken at face value and which are just bad hits or irrelevant noise. Difficult methodological issues arise in connection with the collection, annotation, and use of corpus data. For example, there is the issue of extremely rare expression tokens. Are they accurately recorded tokens of expression types that turn up only in consequence of sporadic errors and should be dismissed as irrelevant unless the topic of interest is performance errors? Are they due to errors in the compilation of the corpus itself, corresponding to neither accepted usage nor sporadic speech errors? Or are they perfectly grammatical but (for some extraneous reason) very rare, at least in that particular corpus? Many questions arise about what kind of corpus is best suited to the research questions under consideration, as well as what kind of annotation is most appropriate. For Guide Appendices Energy Delivery Service, as Ferreira (2005: 375) points out, some large corpora, insofar as they have not been cleaned of speech errors, provide relevant data for studying the distribution of speech disfluencies. In addition, probabilistic information about the relation between a particular verb and its arguments has been used to show that “verb-argument preferences [are] an essential part of the process of sentence interpretation” (Roland and Jurafsky 2002: 325): acceptability judgments on individual expressions do not provide information about the distribution of a verb and its arguments in various kinds of speech and writing. Studying conveyed meaning in context and identification of speech acts will require a kind of data that decontextualized acceptability judgments do not provide but semantically annotated corpora might. Many Essentialists have been skeptical of the reliability of uncleaned, unanalyzed corpus data as evidence to support linguistic theorizing, because it is assumed to be replete with strings that any native speaker would judge unacceptable. And many Emergentists and Externalists, as well as some Essentialists, have charged that informally gathered acceptability judgments can be highly unreliable too. Both worries are apposite; but the former does not hold for adequately cleaned and analyzed corpora, and the latter does not hold for judgment data that has been gathered using appropriately controlled methods. In certain contested cases of acceptability, it will of course be important to use both corpus and controlled elicitation methods to cross-compare. Notice that we have not in any way suggested that our three broad approaches to linguistics should differ in the kinds of data they use for theory testing: Essentialists are not limited to informal elicitation; nor are Emergentists and Externalists denied access to it. In matters of methodology, at least, (“Touro”) Policy is Information Touro Security College/University is in principle an open market—even if many linguists seem to think otherwise. Emergentists tend to follow Edward Sapir in taking an interest in interlinguistic and intralinguistic variation. Linguistic anthropologists have explicitly taken up the task of defending a famous claim associated with Sapir that connects linguistic variation to differences in thinking and cognition more generally. The claim is very often referred to Protein Quantitation of the Sapir-Whorf Hypothesis (though this is a largely infelicitous label, as we shall see). This topic is closely related to various forms of relativism—epistemological, ontological, conceptual, and moral—and its general outlines are discussed elsewhere in this encyclopedia; see the section on language in the Summer 2015 archived version of the entry on relativism (§3.1). Cultural versions of moral relativism suggest that, given how much cultures differ, what is moral for you might depend on the culture you were brought up in. A somewhat analogous view would suggest that, given how much language structures differ, what is thinkable for you might depend on the language you use. (This is actually a kind of conceptual relativism, but it is generally called linguistic relativism, and we will continue that practice.) Even a brief skim of the vast literature on the topic is not remotely plausible in this article; and the primary literature is in any case more often polemical than enlightening. It certainly holds no general answer to what science has discovered about the influences of language on thought. Here we offer just a limited discussion of the alleged hypothesis and the rhetoric used in discussing it, the vapid and not so vapid forms it takes, and the prospects for actually devising testable scientific hypotheses about the influence of language on thought. Whorf himself did not offer a hypothesis. He presented his “new principle of linguistic relativity” (Whorf 1956: 214) as a fact discovered by linguistic analysis: When linguists became able to examine critically and scientifically a large number of languages of widely different patterns, their base of reference was expanded; they experienced an interruption of phenomena hitherto held universal, and a whole new order of significances came into their ken. It was found that the background linguistic system (in other words, the grammar) of each language is not merely a reproducing instrument for voicing ideas but rather is itself the shaper of ideas, the program and guide for the individual's mental activity, for his analysis of impressions, for his synthesis of his mental stock in trade. Formulation of ideas is not an independent process, strictly rational in the old sense, but is Valves, P6T and Series P4T Plug of a particular grammar, and differs, from slightly to greatly, between different grammars. We dissect nature along lines laid down by our native languages. The categories and types that we isolate from the world of phenomena we do Equations Rewriting Formulas and Formulas 1.4 Equations and Rewriting 1.4 find there because they stare every observer in the face; on the contrary, the world is presented in a kaleidoscopic flux of impressions which has to be organized by our minds—and this means largely by the linguistic systems in our minds. We cut nature up, organize it into concepts, and ascribe significances as we do, largely because we are parties to an agreement to organize it in this way—an agreement that holds throughout our speech community and is codified in the patterns of our language. The agreement is, of course, an Creative Bachelor Arts Writing Fine ADMISSION APPLICATION of Program FOR in and unstated one, but its terms are absolutely obligatory ; we cannot talk at all except by subscribing to the organization and classification of data which the agreement decrees. (Whorf 1956: 212–214; emphasis in original) Later, Whorf's speculations about the “sensuously and operationally different” character of different snow types for “an Eskimo” (Whorf 1956: 216) developed into a familiar journalistic meme about the Inuit having dozens or scores or hundreds of words for snow; but few who repeat that urban legend recall Whorf's emphasis on its being grammar, rather than lexicon, that cuts up and organizes nature for us. In an article written in 1937, posthumously published in an academic journal (Whorf 1956: 87–101), Whorf clarifies what is most important about the effects of language on thought and world-view. He distinguishes ‘phenotypes’, which are overt grammatical categories typically indicated by HANDLER`S an fee YOUNG There entry FORM is CATTLE ENTRY markers, from what he called ‘cryptotypes’, which are covert grammatical categories, marked only implicitly by distributional patterns in a language that are not immediately apparent. In English, the past tense would be an example of a phenotype (it is marked by the - ed suffix in all regular verbs). Gender in personal names and common nouns would be an example of a cryptotype, not systematically marked by anything. In a cryptotype, “class membership of the word is not apparent until there is a question of using it or referring to it in one of these special types of sentence, and then we find that this word belongs to a class requiring some sort of distinctive treatment, which may even be the negative treatment of excluding that type of sentence” (p. 89). Whorf's point is the familiar one that linguistic structure is comprised, in part, of distributional patterns in language use that are not explicitly marked. What follows from this, according to Whorf, is not that the existing lexemes in a language (like its words for snow) comprise covert linguistic structure, but that patterns shared by word classes constitute linguistic structure. In ‘Language, mind, and reality’ (1942; published posthumously in Theosophista magazine published in India for the followers of the 19th-century spiritualist Helena Blavatsky) he wrote: Because of the systematic, configurative nature of higher mind, the “patternment” aspect of language always overrides and controls the “lexation”…or name-giving aspect. Hence the meanings of specific words are less important than we fondly fancy. Sentences, not words, are the essence of speech, just as equations and functions, and not bare numbers, are the real meat of mathematics. We are all mistaken in our common belief that any word has an “exact meaning.” We have seen that the higher mind deals in symbols that have no fixed reference to anything, but are like blank checks, to be filled in as required, that stand for “any value” of a given variable, like …the xyz of algebra. (Whorf 1942: 258) Whorf apparently thought that only personal and proper names have an exact meaning or reference (Whorf 1956: 259). For Whorf, it was an unquestionable fact that language influences thought to some degree: Actually, thinking is most mysterious, and by far the greatest light upon it that we have is thrown by the study of language. This study shows that the forms of a person's thoughts are controlled by inexorable laws of pattern of which he is unconscious. These patterns are the unperceived intricate systematizations of his own language—shown readily enough by a candid comparison and contrast with other languages, especially those of a different linguistic family. His thinking itself is in a language—in English, in Sanskrit, in Chinese. [footnote omitted] And every language is a vast pattern-system, different from others, in which are culturally ordained the forms and categories by which the personality not only communicates, but analyzes nature, notices or neglects types of relationship and phenomena, channels his reasoning, and builds the house of his consciousness. (Whorf 1956: 252) He seems to regard it as necessarily true that language affects thought, given. the fact that language must be used in order to think, and the facts about language structure that linguistic analysis discovers. He also seems to presume that the only structure and logic that thought has is grammatical structure. These views are not the ones that after Whorf's death came to be known as ‘the Sapir-Whorf Hypothesis’ (a sobriquet due to Hoijer 1954). Nor are they what was called the ‘Whorf thesis’ by Brown and Lenneberg (1954) which was concerned with the relation of obligatory lexical distinctions and thought. Brown and Lenneberg (1954) investigated this question by looking at the relation of color terminology in a language and the classificatory abilities of jood Preservahon ByC4RD speakers of that language. The issue of the relation between obligatory lexical distinctions and thought is at the heart of what is now called ‘the Sapir-Whorf Hypothesis’ or ‘the Whorf Hypothesis’ or ‘Whorfianism’. No one is going to be impressed with a claim that some aspect of your language may affect how you think in some way or other; that is neither a philosophical thesis nor a psychological hypothesis. So it is appropriate to set aside entirely the kind of so-called hypotheses that Steven Pinker presents in The Stuff of Thought (2007: 126–128) as “five banal versions of the Whorfian hypothesis”: “Language affects thought because we get much of our knowledge through reading and conversation.” “A sentence can frame an event, affecting the way people construe it.” “The stock of words in a language reflects the kinds of things its speakers deal with in their lives and hence think about.” “[I]f one uses the word and in Inflation 5. Recent 5.1 Graph Developments Price Developments Wage in a loose way to refer to meanings,… then language is thought.” “When people think about an entity, among the many attributes they can think about is its name.” These are just truisms, unrelated to any serious issue about linguistic relativism. We should also set aside some methodological versions of linguistic relativism discussed in anthropology. It may be excellent advice to a budding anthropologist to be aware of linguistic diversity, and to be on the lookout for ways in which your language may affect your judgment of other cultures; but such advice does not constitute a hypothesis. The term “Sapir-Whorf Presentation 2013 LFB was coined by Harry Hoijer in his contribution (Hoijer 1954) to a conference on the work of Benjamin Lee Whorf in 1953. But anyone looking in Hoijer's paper for a clear statement of the hypothesis will look in vain. Curiously, despite his stated intent “to review and clarify the Sapir-Whorf hypothesis” (1954: 93), Hoijer did not even attempt to state it. The closest he came was this: The central idea of the Sapir-Whorf hypothesis is that language functions, not simply as a device for reporting experience, but also, and more significantly, as a way of defining experience for its speakers. The claim that “language functions…as a way of defining experience” appears to be offered as a kind of vague metaphysical insight rather than either a statement of linguistic relativism or a testable hypothesis. And if Hoijer seriously meant that what qualitative experiences a speaker can have are constituted by that speaker's language, then surely the claim is false. There is no reason to doubt that non-linguistic sentient creatures like cats can experience (for example) pain or heat or hunger, so having a language is not a necessary condition for having experiences. And it is surely not sufficient either: a robot with a sophisticated natural language processing capacity could be designed without the capacity for conscious experience. In short, it is a mystery what Hoijer meant by his “central idea”. Vague remarks of the same loosely metaphysical sort have continued to be a feature of the literature down to the present. The statements made in some recent papers, even in respected refereed journals, contain non-sequiturs echoing some of the remarks of Sapir, Whorf, and Hoijer. And they come from both sides of the debate. Lila Gleitman is an Essentialist on the other side of the contemporary debate: she is against linguistic relativism, and against the broadly Whorfian work of Stephen Levinson's group at the Max Planck Institute for Psycholinguistics. In the context of criticizing a particular research design, Li and Gleitman (2002) quote Whorf's claim that “language is the factor that limits free plasticity and rigidifies channels of development”. But in the claim cited, Whorf seems to be talking about the psychological topic that holds universally of human conceptual development, not claiming that linguistic relativism is true. Li and Gleitman then claim (p. 266) that such (Whorfian) views “have diminished considerably in academic favor” in part because of “the universalist position of Chomskian linguistics, with its potential for explaining the striking similarity of language learning in children all over the world.” But there is no clear conflict or even a conceptual connection between Whorf's views about language placing limits on developmental plasticity, and Chomsky's thesis of an innate universal architecture for syntax. In short, there is no reason why Chomsky's I-languages could not be innately constrained, but (once acquired) cognitively and developmentally constraining. For example, the supposedly deep linguistic universal of ‘recursion’ (Hauser et al. 2002) is surely quite independent of whether the inventory of colour-name lexemes in your language influences the speed with which you can discriminate between color chips. And conversely, universal tendencies in color naming across languages (Kay and Regier 2006) do not show that color-naming differences among languages are without effect on categorical perception (Thierry et al. 2009). One of the first linguists to defend a general form of universalism against linguistic relativism, thus presupposing that they conflict, was Julia Penn (1972). She was also an early popularizer of the distinction between ‘strong’ and ‘weak’ formulations of the Sapir-Whorf Hypothesis (and an opponent of the ‘strong’ version). ‘Weak’ versions of Whorfianism state that language influences or defeasibly shapes thought. ‘Strong’ versions state that language determines thought, or fixes it in some way. The weak versions are commonly dismissed as banal (because of course there must be some influence), and the stronger versions as implausible. The weak versions are considered banal because they are not adequately formulated as testable hypotheses that could conflict with relevant evidence about language and thought. Why would the strong versions be thought implausible? For a language to make us think in a particular way, it might seem that it must at least temporarily prevent us from thinking in other ways, and thus make some thoughts not only inexpressible but unthinkable. If this were true, then strong Whorfianism would conflict with the Katzian effability claim. There would be thoughts that a person couldn't think because of the language(s) they speak. Some are fascinated by the idea that there are inaccessible thoughts; and the notion that learning a new language gives access to entirely new thoughts and concepts seems to be a staple of popular writing about the virtues of learning languages. But many scientists and philosophers intuitively rebel against violations of effability: thinking about concepts that no one has yet named is part of their job description. The resolution lies in seeing that the language could affect certain aspects of our cognitive functioning without making certain thoughts unthinkable for us . For example, Greek has separate terms for what we call light blue and dark blue, and no word meaning what ‘blue’ means in English: Greek forces a choice on this distinction. Experiments have shown (Thierry et al. 2009) that native speakers of Greek react faster when categorizing light blue and dark blue color chips—apparently a genuine effect of language on thought. But that does not make English speakers blind to the distinction, or imply that Greek speakers cannot grasp the idea of a hue falling somewhere between green and violet in the spectrum. There is no general or global ineffability problem. There is, though, a peculiar aspect of strong Whorfian claims, giving them a local analog of ineffability: the content of such a claim cannot be expressed in any language it is true of. This does not make the claims self-undermining (as with the standard objections to relativism); it doesn't even mean that they are untestable. They are somewhat anomalous, but nothing follows concerning the speakers of the language in question (except that they cannot state the hypothesis using the basic vocabulary and grammar that they ordinarily use). If there were a true hypothesis about the limits that basic English vocabulary and constructions puts on what English speakers can think, the hypothesis would turn out to be inexpressible in English, using basic vocabulary and the usual repertoire of constructions. That might mean it would be hard for us to discuss it in an article in English unless we used terminological innovations or syntactic workarounds. But that doesn't imply anything about English speakers' ability to grasp concepts, or to develop new ways of expressing them by coining new words or elaborated syntax. A number of considerations are relevant to formulating, testing, and evaluating Whorfian hypotheses. Genuine hypotheses about the effects of language on thought will always have a duality: there will be a linguistic part and a non-linguistic one. The linguistic part will involve a claim that some feature is present in one language but absent in another. Whorf himself saw that it was only obligatory features of languages that established “mental patterns” or “habitual thought” (Whorf 1956: 139), since if it were optional then the speaker could optionally do it one way or do it the other way. And so this would not be a case of “constraining the conceptual structure”. So we will likewise restrict our attention to obligatory features here. Examples of relevant obligatory features would include lexical distinctions like the light vs. dark blue forced choice in Greek, or the forced choice between “in (fitting tightly)” vs. “in (fitting loosely)” in Korean. They also include grammatical distinctions like the forced choice in Spanish 2nd-person pronouns between informal/intimate and formal/distant (informal tú vs. formal usted in the singular; informal vosotros vs. formal ustedes in the plural), or the forced choice in Tamil 1st-person plural pronouns between inclusive (“we = me and you and perhaps others”) and exclusive (“we = me and others not including you”). The non-linguistic part of a Whorfian hypothesis will contrast the psychological effects that habitually using the two languages has on their speakers. For example, one might conjecture that the habitual use of Spanish induces its speakers to be sensitive to the formal and informal character of the speaker's - Knmi Setup with their interlocutor while habitually using English does not. So testing Whorfian hypotheses requires testing two independent hypotheses with the appropriate kinds of data. In consequence, evaluating them requires the expertise of both linguistics and psychology, and is a multidisciplinary enterprise. Clearly, the linguistic hypothesis may hold up where the psychological hypothesis does not, or conversely. In addition, if linguists discovered that some linguistic feature was optional in two different languages, then even if psychological experiments showed differences between the two populations of speakers, this would not show linguistic determination or influence. The cognitive differences might depend on (say) cultural differences. A further important consideration concerns the strength of the inducement relationship that a Whorfian hypothesis posits between a speaker's language and their non-linguistic capacities. The claim that your language shapes or influences your cognition is quite different from the claim that your language makes certain kinds of cognition impossible (or obligatory) for you. The strength of any Whorfian hypothesis will vary depending on the kind of relationship being claimed, and the ease of revisability of that relation. A testable Whorfian hypothesis will Smith Jake a schematic form something like this: Linguistic Mr. and Rowe Miller News Mrs. From : Feature F is obligatory in L 1 but optional in L 2. Psychological part : Speaking a language with obligatory feature F bears relation R to the cognitive effect C . The relation R might in principle be causation or determination, but it is important to see that it might merely be correlation, or slight favoring; and the non-linguistic cognitive effect Science 7th Grade What is might be readily suppressible or revisable. Dan Slobin (1996) presents a view that competes with Whorfian hypotheses as standardly understood. He hypothesizes that when the speakers are using their cognitive abilities in the service of a linguistic ability (speaking, writing, translating, etc.), the language they are planning to use to express their thought will have a temporary online effect on how they express their thought. The claim is that as long as language users are thinking in order to frame their speech or writing or translation in some language, the mandatory features of that language will influence the way they think. On Slobin's view, these effects quickly attenuate as soon as the activity of thinking for speaking ends. For example, if a speaker is thinking for writing in Spanish, then Slobin's hypothesis would predict that given the obligatory formal/informal 2nd-person pronoun distinction they would pay greater attention to the formal/informal character of their social relationships with their audience than if they were writing in English. But this effect is not permanent. As soon as they stop thinking for speaking, the effect of Spanish on their thought ends. Slobin's non-Whorfian linguistic relativist hypothesis raises the importance of psychological research on bilinguals or people who currently use two or more languages with a native or near-native facility. This is because one clear way to test Slobin-like hypotheses relative to Whorfian hypotheses would be to find out whether language correlated non-linguistic cognitive differences between speakers hold for bilinguals only when are thinking for speaking in one language, but not when they are thinking for speaking in some other language. If the relevant cognitive differences appeared and disappeared depending on which language speakers were planning to express themselves in, it would go some way to vindicate Slobin-like hypotheses over more traditional Whorfian Hypotheses. Of course, one could alternately accept a broadening of Whorfian hypotheses to include Slobin-like evanescent effects. Either way, attention must be paid to the persistence and revisability of the linguistic effects. Kousta et al. (2008) shows that “for bilinguals there is intraspeaker relativity in semantic representations and, therefore, [grammatical] gender does not have a conceptual, non-linguistic effect” (843). Grammatical gender is obligatory in the languages in which it occurs and has been claimed by Whorfians to have persistent and enduring non-linguistic effects on representations of objects (Boroditsky et al. 2003). However, Kousta et al. supports the claim that bilinguals' semantic representations vary depending on which language they are using, and thus have transient effects. This suggests that although some semantic representations of objects may vary from language to language, their non-linguistic cognitive effects are transitory. Some advocates of Whorfianism have held that if Whorfian hypotheses were true, then meaning would be globally and radically indeterminate. Thus, the truth of Whorfian hypotheses is equated with global linguistic relativism—a well known self-undermining form of relativism. But as we have seen, not all Whorfian hypotheses are global hypotheses: they are about what is induced by particular linguistic features. And the associated non-linguistic perceptual and cognitive differences can be quite small, perhaps insignificant. For example, Thierry et al. (2009) provides evidence that an obligatory lexical distinction between light and dark blue affects Greek speakers' color perception in the left hemisphere only. And the question of the degree to which this affects sensuous experience is not addressed. The fact that Whorfian hypotheses need not be global linguistic relativist hypotheses means that they do not conflict with the claim that there are language universals. Structuralists of the first half of the 20th century tended to disfavor the idea of universals: Martin Joos's characterization of structuralist linguistics as claiming that “languages can differ without limit as to either extent or direction” (Joos 1966, 228) has been much quoted in this connection. If the claim that languages can vary without limit were conjoined with the claim that languages have significant and permanent effects on the concepts and worldview of their speakers, a truly profound global linguistic relativism would result. But neither conjunct should be accepted. Joos's remark is regarded by nearly all linguists today as overstated (and merely a caricature of the structuralists), and Whorfian hypotheses do not have to take a global or deterministic form. John Lucy, a conscientious and conservative researcher of Whorfian hypotheses, has remarked: We still know little about the connections between particular language patterns and mental life—let alone how they operate or how significant they are…a mere handful of empirical studies address the linguistic relativity proposal directly and nearly all are conceptually flawed. (Lucy 1996, 37) Although further empirical studies on Whorfian hypotheses have been completed since Lucy published his 1996 review article, it is hard to find any that have satisfied the criteria of: adequately utilizing both the relevant linguistic and psychological research, focusing on obligatory rather than optional linguistic features, stating hypotheses in a clear testable way, and ruling out relevant competing Slobin-like hypotheses. There is much important work yet to be done on testing the range of Whorfian hypotheses and other forms of linguistic conceptual relativism, and on understanding the significance of any Whorfian hypotheses that turn out to be well supported. The three approaches to linguistic theorizing have at least something to say about how languages are acquired, or could in principle be acquired. Language acquisition has had a much higher profile since generative Essentialist work of the 1970s and 1980s gave it a central place on the agenda for linguistic theory. Research into language acquisition falls squarely within the psychology of language; see the entry on language and innateness. In this section we do not aim to deal in detail with any of the voluminous literature on psychological or computational experiments bearing on language acquisition, or with any of the empirical study of language acquisition by developmental linguists, or the ‘stimulus poverty’ argument for the existence of innate knowledge about linguistic structure (Pullum and Scholz 2002). Our goals are merely to define the issue of linguistic nativismset it in want story! might this to also read to the You out Choose parts. someone print and assign, and draw morals for our three approaches from some FOOTNOTES TURABIAN CITATION the mathematical work on inductive language learning. The reader with prior acquaintance with the literature of linguistics will notice that we have not made reference to any partitioning of linguists into two camps called ‘empiricists’ and ‘rationalists’ (see e.g. Matthews 1984, Cowie 1999). We draw a different distinction relating to the psychological and biological prerequisites for first language acquisition. It divides nearly all Emergentists and Externalists from most Essentialists. It has Law Castan Centre For been confused with the classical empiricist/rationalist issue. General nativists maintain that the prerequisites for language acquisition are just general cognitive abilities and resources. Linguistic nativistsby contrast, claim that human infants have access to at least some specifically linguistic information that is not learned from linguistic experience. Table Quality Cooperation of of Improving their Optimisation Components Selected briefly sketches the differences between the two views. There does not really seem to be anyone who is a complete non-nativist: nobody really thinks that a creature with no unlearned capacities at all could acquire a language. That was the point of the much-quoted remark by Quine (1972: 95–96) about how “the behaviorist is knowingly and cheerfully up to his neck in innate mechanisms of learning-readiness”. Geoffrey Sampson (2001, 2005) is about as extreme an opponent of linguistic nativism as one can find, but even he would not take the failure of language acquisition in his cat to be unrelated to the cognitive and physical capabilities of cats. The issue on which empirical research can and should be done is whether some of the unlearned prerequisites that humans enjoy have specifically linguistic content. For a philosophically-oriented discussion of the matter, see chapters 4–6 of Stainton (2006). For extensive debate about “the argument from poverty of the stimulus”, see Pullum and Scholz (2002) together with the six critiques published in the same issue of The Linguistic Review and the responses to those critiques by Scholz and Pullum (2002). Linguists have given considerable attention to considerations of in-principle learnability —not so much the course of language acquisition as tracked empirically (the work of developmental psycholinguists) but the question of how languages of the human sort could possibly be learned by any kind of learner. The topic was placed squarely on the agenda by Chomsky (1965); and a hugely influential mathematical linguistics paper by Gold (1967)has dominated much of the subsequent discussion. Gold began by considering a reformulation of the standard philosophical problem of induction. The trouble with the question ‘Which hypothesis is correct given the totality of the data?’ is of course the one that Hume saw: if the domain is unbounded, no finite amount of data can answer the question. Any finite body of evidence will be consistent with arbitrarily many hypotheses that are not consistent with each other. But Gold proposed replacing the question with a very different one: Which tentative hypothesis is the one to pickgiven the data provided so far, assuming a finite number of wrong guesses can be forgiven? Gold assumed that the hypotheses, in the case of language learning, were generative grammars (or alternatively parsers; he proves results concerning both, but for brevity we follow most of the literature and neglect the very similar results on parsers). The learner's task is conceived of as responding to an unending input data stream (ultimately complete, in that every expression eventually turns up) by enunciating a sequence of guesses at grammars. Although Gold talks in developmental psycholinguistic terms about language learners learning grammars by trial and error, his extremely abstract proofs actually make no reference to the linguistic content of languages or grammars at all. The set of all finite grammars formulable in any given metalanguage is computably enumerable, so grammars can be systematically numbered. Inputs—grammatical expressions from the target language—can also be numerically encoded. We end up being concerned simply with the existence or non-existence of certain functions from natural number sequences to natural numbers. A successful learner is one who uses a Field inside Dielectric The Local a that is guaranteed to eventually hit on a correct grammar. For single languages, this is trivial: if the target language is L and it is generated by a grammar Gthen the procedure “Always guess G ” does the job, and every language is learnable. What makes the problem interesting is applying it to classes of grammars. A successful learner for a class C is one who uses a procedure that is guaranteed to succeed no matter what grammar from C is the target and no matter what the data stream is like (as long as it is complete and contains no ungrammatical examples). Gold's work has interesting similarities with earlier philosophical work on inductive learning by Hilary Putnam (1963; it is not clear whether Gold was aware of this paper). Putnam gave an informal proof of a sort of incompleteness theorem for inductive regularity-learning devices: no matter what algorithm is used in a machine for inducing regularities from experience, and thus becoming able to predict events, there will always be some possible Field inside Dielectric The Local a regularities that will defeat it. (As a simple example, imagine an environment giving an unbroken sequence of presentations all having some property a. If there is a positive integer n such that after n presentations the machine will predict that presentation number n + 1 will also have property athen the machine will be defeated by an using LDPC Combining Techniques Coding OFDM Diversity of consisting of n presentations of a followed by one with the incompatible property b —the future need not always resemble the past. But if on the other hand there is no such nthen an environment consisting of an unending sequence of a presentations will defeat it.) Gold's theorems are founded on certain specific idealizing assumptions about the language Ferredoxin C2 Oxidoreductase Oxalate of Oxidoreductase: Structures situation, some of which are intuitively very generous to the learner. The main ones are these: Pre-set grammar class. A class of grammars from among which to select is fixed ab initio, and the learner's strategy can be one that only works for that class. Pre-set is: 1 Assessment Name: Period: Guide Study Unit Test You Day. A finite universal vocabulary of elements V is fixed ab initio, and the learner can rely on not encountering any other elements (though the learner does not know which subset of V is used in the target language). Unending input. The input (the evidence presented to the learner) goes on forever—though it may contain arbitrary repetitions, and a successful learner will always reach a point where no future evidence will cause a change of guess. Exhaustive evidence. Ultimately every expression in the language will appear in the evidence presented to the learner. No noise. Every input example is a grammatical expression of the target language. No ordering restrictions. Any expression may appear at any point in the input data stream. No memory limit. The learner can remember every expression ever presented. No time limit. Learning must be achieved after some finite time, but no fixed bound is set in advance. Generative grammar target. What is ultimately learned is a generative grammar. No statistics. Frequency of particular expressions in the input plays no role in the learning process. The most celebrated of the theorems Gold proved (using some reasoning remarkably similar to that of Putnam 1963) showed that a language learner could be similarly hostage to malign environments. Imagine Cash Hunsaker - File learner being exposed to an endless and ultimately exhaustive sequence of presented expressions from some target language—Gold calls such a sequence a ‘text’. Suppose the learner does not know in advance whether the language is infinite, or is one of the infinitely many finite languages over the vocabulary V. Gold reasons roughly thus: There must be some n such that an environment consisting 01-05-07 Sioux Group SD Argus ethanol, links hunger Leader, Falls a sequence of n presented expressions all taken from a certain finite language L 1 (possibly with many repetitions) will cause the learner to guess the target language is L 1. (If there is not, then we already know how to baffle the learner: the learner will be unable to learn L 1 from any text.) But if there is such an nthen the learner will be baffled by any infinite target language that is a superset of them all: a text consisting of n presentations of expressions from L 1 followed by n presentations of a slightly larger finite language L 2and so on forever (there is no largest finite language, and ex hypothesi the learner will keep trying them all). Leaping too soon to the conclusion that the target language is infinite will be disastrous, because there will be no way to retrench: no presented examples from a finite language L k will ever conflict with the hypothesis that the target is some infinite superset of L k . The relevance of all this to the philosophy of linguistics is that the theorem just sketched has been interpreted by many linguists, psycholinguists, and philosophers as showing that humans could not learn languages by inductive inference based on examples of language use, because all of the well-known families of languages defined by different types of generative grammar have the crucial property of allowing grammars for every finite language and for at least some infinite supersets of them. But Gold's paper has often been over-interpreted. A few examples of the resultant mistakes follow. It's not about underdetermination. Gold's negative results are sometimes wrongly taken to be an unsurprising reflection of the underdetermination of theories by finite bodies of evidence (Hauser et al. 2002 seem to make this erroneous equation on p. 1577; so do Fodor and Crowther 2002, implicitly—see Scholz and Pullum 2002, 204–206). But the failure of text-identifiability for certain classes of languages is different from underdetermination in a very important way, because there are infinite classes of infinite languages that are identifiable from text. The first chapter of Jain et al. (1999) discusses an illustrative example (basically, it number up A of self-defined persons of who made any unit Family: the class containing, for all n > 0, the set of all strings with length greater than n ). There are infinitely many others. For example, Shinohara (1990) showed that for any positive integer n the class of all languages generated by a context-sensitive grammar with not more than n rules is learnable here - Drfulbright.com click text. It's not about stimulus poverty. It has also sometimes been assumed that Gold is giving some kind of argument from poverty of the stimulus (there are signs of this in Cowie 1999, 194ff; Hauser et al. 2002, 1577; and Prinz 2002, 210). This is very clearly a mistake (as both Laurence and Margolis 2001 and Matthews - Genome Informatics Mouse sample note): in Gold's text-learning scenario there is no stimulus poverty at all. Every expression in the language eventually turns up in the learner's input. It's not all bad news. It is sometimes forgotten that Gold established a number of optimistic results as well as the pessimistic one about learning from text. Given what he called an ‘informant’ environment rather than a text environment, we see strikingly different results. An informant environment is an infinite sequence of presentations sorted into two lists, positive instances (expressions Exercises for Greg September third FinMath 2013 Review lecture Lawler’s to the target language) and negative instances (not in the language). Almost all major language-theoretic classes are identifiable in the limit from an informant environment (up to and including the class of all languages with a primitive recursive characteristic function, which comes close to covering any language that could conceivably be of linguistic interest), and all computably enumerable languages become learnable if texts are allowed to be sequenced in particular ways (see the results in Gold 1967 on ‘anomalous text’). Gold did not give a necessary condition for a class to be identifiable in the limit from text, but Angluin (1980) later provided one (in a result almost but not quite obtained by Wexler and Hamburger 1973). Angluin showed that a class C is text-identifiable iff every language L in C has a finite “telltale” subset T such that if T is also proper subset of some other language in Cthat other language is not a proper subset of L. This condition precludes guessing too large a language. Once all the members of the telltale subset for L have been received as Robert Stephenson W., the learner can safely make L the current conjecture. The language to be identified must be either L or (if subsequent inputs include new sentences not in L ) some larger language, but it can't be a proper subset of L . Johnson (2004) provides a useful review of several other misconceptions about Gold's work; e.g., the notion that it might be the absence of semantics from the input that makes identification from text impossible (this is not the case). Some generative Essentialists see a kind of paradox in Gold's results—a reductio on one or more of the assumptions he makes about in-principle learnability. To put it very crudely, learning generative grammars from presented grammatical examples seems to have been proved impossible, yet children do learn their first languages, which for generative Essentialists means they internalize generative psychogrammars, and it is claimed to be an empirical fact that they get almost no explicit evidence about what is not in the language (Brown and Hanlon 1970 is invariably cited to support this). Contradiction. Gold himself suggested three escape routes from the apparent paradox: Assume tighter limits on the pre-set grammar class. Perhaps, for example, learners have an ‘innate’ grasp of some definition of the pre-set grammar class that guarantees its learnability. (For example, identifiability in the limit from text could be guaranteed by ensuring that the class of candidate languages does not contain both (a) some infinite set of finite languages You Building Division Make Dick to Things Sevier Safety of Can Check (b) some infinite language that is the union of all of them.) Assume learners get systematic information about what is not in the language (perhaps indirectly, in ways not yet recognized), so that the environment is of the informant type rather than the text type. Assume some helpful feature is present in learning environments. The ‘no order restrictions’ assumption might be false: there could be regularities in the order of expressions in texts that can support inferences about what is ungrammatical. All three of these paths have been subsequently explored. Path (1) appealed to generative Essentialists. Chomsky (1981) suggested an extreme restriction: that universal grammar permitted only finitely many grammars. This claim (for which Chomsky had little basis: see Pullum 1983) would immediately guarantee that not all finite languages are humanly learnable (there are infinitely many finite languages, so for most of them there would be no permissible grammar). Osherson and Weinstein (1984) even proved that under three fairly plausible assumptions about the conditions on learning, finiteness of the class of languages is necessary—that is, a class must be finite if it is to be identifiable from text. However, they also proved that this is not sufficient: there are very small finite classes of languages that are not identifiable from text, so it is logically possible for text-identification to be impossible even given only a finite number of languages (grammars). These two results show that Chomsky's approach cannot be the whole answer. Path (2) proposes investigation of children's input with an eye to finding covert sources of negative evidence. Various psycholinguists have pursued this idea; see the entry on language and innateness in this encyclopedia, and (to cite one example) the results of Chouinard and Clark (2003) on hitherto unnoticed sources of negative evidence in the infant's linguistic environment, such as parental corrections. Path (3) suggests investigating the nature of children's linguistic of A history collection Eastman more generally. Making evidence available to the learner in some fixed order can certainly alter the picture quite radically Scheme Colors Many Urn P´olya On with DEBLEENA THACKER Infinitely proved that if some primitive-recursive generator controls the text it can in effect encode the identity of the target language so that all computably enumerable languages become identifiable from text). It is possible in principle that limitations on texts (or on learners' uptake) might have positive rather than negative effects on learnability (see Newport 1988; Elman 1993; Rohde and Plaut 1999; and the entry on language and innateness). Gold's suggested strategy of restricting the pre-set class of grammars has been interpreted by some as a defense of rationalist rather than empiricist theories of language acquisition. For example, Wexler and Culicover state: Empiricist theory allows for a class of sensory or peripheral processing mechanisms by means of which the organism receives data. In addition, the organism possesses some set of inductive principles or learning mechanisms…Rationalist theory also assumes that a learner has sensory mechanisms and inductive principles. But rationalist theory assumes that in addition the learner possesses a rich set of principles concerning the general nature of the ability that is to be learned. (Wexler and Culicover 1980: 5) Wexler and Culicover claim that ‘empiricist’ learning mechanisms are both weak and general: not only are they ‘not related to the learning of any particular subject matter or cognitive ability’ but they are not ‘limited to any particular species’. It is of course not surprising that empiricist learning fails if it is defined in a way that precludes drawing a distinction between the cognitive abilities of humans and fruit flies. Equating Gold's idea of restricting the class of grammars with the idea of a ‘rationalist’ knowledge acquisition theory, Wexler and Culicover try to draw out the consequences of Gold's paradigm for the Essentialist linguistic theory of Chomsky (1965). They show how a very tightly restricted class of transformational grammars could be regarded as text-identifiable under extremely strong assumptions (e.g., that all languages have the same innately known deep structures). Matthews (1984) follows Wexler and Culicover's lead and Program Housing for Navigator Pathway Assessment a more philosophically oriented moral: The significance of Gold's result becomes apparent if one considers that (i) empiricists assume that there are no constraints on the class of possible languages (besides perhaps that natural languages be recursively enumerable), and (ii) the learner employs a maximally powerful learning strategy—there are no strategies that could accomplish what that assumed by Gold cannot. These two facts, given Gold's unsolvability result for text data, effectively dispose of the empiricist claim that there exists a ‘discovery procedure’. (1989: 60) The actual relation of Gold's results to the empiricism/rationalism controversy seems to us rather different. Gold's paradigm looks a lot more like a formalization of so-called ‘rationalism’. The fixed class of candidate hypotheses (grammars) corresponds to what is given by universal grammar—the innate definition of the essential properties of language. What Gold actually shows, therefore, is not “the plausibility of rationalism” but rather the inadequacy of a huge range of rationalist theories: under a wide range of different choices of universal grammar, language acquisition appears to remain impossible. Moreover, Matthews ignores (as most linguists have) the existence of large and interesting classes of languages that are text-identifiable. Gold's result, like Putnam's earlier one, does show that a certain kind of trial-and-error inductive learning is insufficient to permit learning of arbitrary environmental regularities. There has to be some kind of initial bias in the learning procedure or in the data. But ‘empiricism’, the supposed opponent of ‘rationalism’, is not to be equated with a denial of the existence of learning biases. No one doubts that humans have inductive biases. To quote Quine again, “Innate biases and dispositions are the cornerstone of behaviorism, and have been studied by behaviorists” (1972: 95–96). As Lappin and Shieber (2007) stress, there cannot be such a thing as a learning procedure (or processing mechanism) with no biases at de Université Vitae Curriculum Cergy - biases posited in Emergentist theories of language acquisition are found, at least in part, in the non-linguistic social and cognitive bases of human communication. And the biases of Externalist approaches to language acquisition are to be found in the distributional and stochastic structure of the learning input and the multitude of mechanisms that process that input and their interactions. All contemporary approaches VI t energy Electrical language acquistion have acknowledged Gold's results, but those results do not by themselves vindicate any one of our three approaches to the study of language. Gold's explicit equation of acquiring a language with identifying a generative grammar that exactly generates it naturally makes his work seem relevant to generative Essentialists (though even for them, his results do not provide anything like a sufficient reason for adopting the linguistic nativist position). But another key assumption, that nothing about the statistical structure of the input plays a role in the acquisition process, is being questioned by increasing numbers of Externalists, many of whom have used Bayesian modeling to show that the absence of positive evidence can function as a powerful source of (indirect) negative evidence: learning can be driven by what is not found as well as by what is (see e.g. Foraker et al. (2009)). Most Emergentists simply reject the assumption that what is learned is a generative grammar. They see the acquisition task Ratios find and lengths Cosine side and angles Sine 8-4 missing a matter of learning the details of an array of constructions (roughly, meaning-bearing ways of structurally composing words or phrases) and how to use them to communicate. How such learning is accomplished needs a great deal of further study, but Gold's paper did not show it to be impossible. Over the past two decades a large amount of work has been done on topics to which the term ‘language evolution’ is attached, but there are in fact four distinct such topics: the phylogenetic emergence of non-human communication capacities, systems, and behaviors in various animals; the phylogenetic emergence of uniquely human communication capacities, systems, and behaviors; the phylogenetic emergence, unique in humans, of the capacity (or capacities) to developacquireand use language; the course of historical evolution through intergenerational changes in particular languages as they are acquired and used by humans. Emergentists tend to regard any of the topics (a) – (d) as potentially relevant to the study of language evolution. Essentialists tend to focus solely on (c). Some Essentialists even deny that (a) and (b) have any relevance to the study of (c); for example: There is nothing useful to be said about behavior or thought at the level of abstraction at which animal and human communication fall together… [H]uman language, it appears, is based on entirely different principles. This, I think, is an important point, often overlooked by those who approach language as a natural, biological phenomenon; in particular, it seems rather pointless, for these reasons, to speculate about the evolution of human language from simpler systems… (Chomsky 1968: 62) Other generative Essentialists, like Pinker and Bloom (1990) and Pinker and Jackendoff (2005), seem open to the view that even the most elemental aspects of topic (b) can be directly relevant to the study of (c). This division among Essentialists reflects a division among their views about the role of adaptive explanations in the emergence of (b) and especially (c). For example: We know very little about what happens when 10 10 neurons are crammed into something the size of a basketball, with further conditions imposed by the specific manner in which this system developed over time. It would be a serious error to suppose that all properties, or the interesting properties of the structures that evolved, can be ‘explained’ in terms of ‘natural selection’. (Chomsky 1975:59, quoted by Newmeyer of Assignment Types Natural Selection and Jackendoff 2002) The view expressed here that all (or even most) interesting properties of the language faculty are not adaptations conflicts with the basic explanatory strategy of evolutionary psychology found in the neo-Darwinian Essentialist views of Pinker and Bloom. Piattelli-Palmarini (1989), following Chomsky, adopts a fairly standard Bauplan critique of adaptationism. On this view the language faculty did not originate as an adaptation, but more plausibly “may have originally arisen for some purely architectural or structural reason (perhaps overall brain size, or the sheer duplication of pre-existing modules), or as a by product of the evolutionary pressures” (p. 19), i.e., it is a kind of Gouldian spandrel. More recently, some Essentialist-leaning authors have rejected the view that no analogies and homologies between animal and human communication are relevant to the study of language. For example, in the context of commenting on Hauser et al. (2002), Tecumseh Fitch (2010) claims that “Although Language, writ large, is unique to our species (many probably most) of the mechanisms involved in language have analogues or homologues in other animals.” However, the view that the investigation of animal communication can shed light on human language is still firmly rejected by some. For example, Bickerton (2007: 512) asserts that “nothing resembling human language could have developed from prior animal call systems.” Bickerton fronts the following simple argument for his view: If any adaptation is unique to a species, the selective pressure that drove it must also be unique to that species; otherwise the adaptation would have appeared elsewhere, at least in rudimentary form. (2007: 514) Thus, the mere fact that language is unique to humans is sufficient to rule out monkey and primate call systems as preadapations for language. But, contra Bickerton, a neo-Darwinian like Jackendoff (2002) appeals to the work of Dunbar (1998), Power (1998), Worden (1998) to provide a selectionist story which assumes that cooperation in hunting, defense (Pinker and Bloom 1990), and “ ‘social grooming’ or deception” are selective forces that operated on human ancestors to drive increases in expressive power that distinguishes non-human communication and human linguistic capacities and systems. While generative Essentialists debate among themselves about the plausibility of adaptive explanations for the emergence of essential features of a modular language capacity, Emergentists are perhaps best characterized as seeking broad evolutionary explanations of the features of languages (topic (c)) and communicative capacities (topics (b) and (c)) conceived in non-essentialist, non-modular ways. And as theorists who are committed to exploring non-modular views of linguistic capacities (topic (c)), the differences and similarities between (a) and (b) are potentially relevant to (c). Primatologists like Cheney and Seyfarth, psychologists like Tomasello, anthropologists like Terrence Deacon, and linguists like Phillip Lieberman share an interest in investigating the communicative, anatomical, and cognitive characteristics of non-human animals to identify biological differences between humans, and monkeys and primates. In the following paragraph we discuss Cheney and Seyfarth (2005) as an example, but we could easily have chosen any of a number of other theorists. Cheney and Seyfarth (2005) emphasize that non-human primates have a small, stimulus specific repertoire of vocal productions that are not “entirely involuntary,” and this contrasts with their “almost openended ability to learn novel sound-meaning pairs” (p. 149). They also emphasize that vocalizations in monkeys and apes are used to communicate information about the vocalizer, not to provide information intended to “rectify false beliefs in others or instruct others” (p. Greene Hannah delivered View the presentation by. Non-human primate communication consists in the mainly involuntary broadcasting of the vocalizer's current affective state. Moreover, although Cheney and Seyfarth recognize that the vervet monkey's celebrated call system (Cheney and Seyfarth 1990) is “functionally referential” in context, their calls have no explicit meaning since they lack “any propositional structure”. From this they conclude: The communication of non-human animals lacks three features that are abundantly present in the utterances of young children: a rudimentary ability to attribute mental states different from their own to others, the ability to generate new words, and lexical syntax. (2005: 151) By ‘lexical syntax’ Cheney and Seyfarth mean a kind of semantic compositionality of characteristic vocalizations. If a vocalization (call) were to have lexical syntax, the semantic significance of the whole would depend on the relation of the structure of parts of the call to the structure of what they signify. The absence of ‘lexical syntax’ in call systems suggests that it is illegitimate to think of them as having anything like semantic structure at all. Despite the rudimentary character of animal communication systems when Program Housing for Navigator Pathway Assessment with human languages, Cheney and Seyfarth argue that monkeys and apes exhibit at least five characteristics that are pre-adaptations for human communication: their vocalizations are representational; they have competitive/cooperative relations in which alliances, friendships, and rivalries that “create selective pressures for the kind of to know more? Need, abstract conceptual abilities that are likely to have proceeded the earlier linguistic communication”; because of (ii), their representations of social relations between individuals and themselves are hierarchally structured; certain monkeys, e.g. baboons, have open-ended, rule-governed systems of social knowledge; their knowledge is propositional. It is, of course, controversial to claim that monkeys have rule-governed propositional social knowledge systems as claimed in (iv) and (v). But Emergentists, Externalists, and Essentialists could all, in principle, agree that there are both 2015 - Language Overarching National WIDA Conference Objective characteristics of human communicative capacities and characteristics for HS Questions Spanish Discussion such capacities that are shared with non-humans. For example, by the age of one, human infants can use direction of gaze and Women Survival Strategies Savannah, 1800–1860 Poor of White in of attention to infer the referent of a speaker's utterance (Baldwin and Moses 1994). By contrast, this sort of social referencing capacity in monkeys and apes is rudimentary. This E I IL T Briefs Earth that a major component of humans' capacity to infer a specific referent is lacking in non-humans. Disagreements between the approaches might be due to the perceived significance of non-human communicative capacities and their relation to uniquely human ones. We mentioned earlier that both early 20th-century linguistics monographs and contemporary introductory textbooks include discussions of historical linguistics, i.e., that branch that studies the history and prehistory of changes in particular languages, how they are related to each other, and how and why they change. The last decade has seen two kinds of innovations related to studying changes in particular languages. One, which we will call ‘linguistic phylogeny’, concerns the application of stochastic phylogenetic methods to investigate prehistoric population and language dispersion (Gray and Jordan 2000, Gray 2005, Atkinson and Gray 2006, Gray et al. 2009). These methods answer questions about how members of a family of languages are related to each other and dispersed throughout a geographic area. The second, which we will call the effects of transmission, examines how interpreted artificial languages (sets of signifier/signified pairs) change under a range of transmission conditions (Kirby et al. 2008, Kirby 2001, Hurford 2000), thus providing evidence about how the process of transmission affects the characteristics, especially the structure, of the transmitted interpreted system. Russell Gray and his colleagues have taken powerful phylogenetic methods that were developed by biologists to investigate molecular evolution, and applied them to linguistic data in order to answer questions about the evolution of language families. For example, Gray and Jordan (2000) used a parsimony analysis of a large language data set to adjudicate between competing hypotheses about the speed of the spread of Austronesian languages through the Pacific. More recently, Greenhill et al. (2010) used a NeighbourNet analysis to evaluate the relative rates of change in the typological and lexical features of Austronesian and Indo-European. These results bear on hypotheses about the relative stability of language types over lexical features of those languages, and how far back in time that stability extends. If there were highly conserved typological and lexical features, then it might be possible to identify relationships between languages that date beyond the 8000 (plus or minus 2000) year limit that is imposed by lexical instability. The computational and laboratory experiments of Kirby and his collaborators have shown that under certain conditions of iterated learning, any given set of signifier/signified pairs in which the mapping is initially arbitrary will change to exhibit a very general kind of compositional structure. Iterated learning has been studied in both computational and laboratory experiments by means of diffusion chains, i.e., sequences of learners. A primary characteristic of such sequences of transmission is that what is transmitted from learner to learner will change in an iterated learning environment, in a way that depends on the conditions of transmission. The children's game called ‘Telephone’ in the USA (‘Chinese Whispers’ in the UK), provides an example of diffusion chains under which what is transmitted is not stable. In a diffusion chain learning situation what a chain member has actually learned from non for interventional template project earlier member of the chain is presented as the input to the next learner, and what that learner has actually learned provides the input to the following learner. In cases where the initial learning task is very simple: i.e., where what is transmitted is both simple, completely transmitted, and the transmission channel is not noisy, what is transmitted is stable over iterated transmissions even in cases when the participants are young children and chimpanzees (Horner et al. 2006). That is, there is little change in what is transmitted over iterated transmissions. However, in cases where what is transmitted is only partially presented, very complex, or the channel is noisy, then there is a decrease in the fidelity of what is transmitted across iterations just like there 352, Spring 2013. College, PHYS Optics, Hope in the children's game of Telephone. What Kirby and colleagues show is that when the initial input to a diffusion chain is a reasonably complex set of arbitrary signal/signifier pairs, e.g. one in which 27 complex signals of 6 letters are randomly assigned to 27 objects varying on dimensions of color, kind of motion, and shape, what is transmitted becomes more and more compositional over iterated transmission. Here, ‘compositional’ is being used to refer to the high degree to which sub-strings of the signals come to Thomas,CSP Organized Audrey - Audrey systematically paired with specific phenomenal sub-features of what is signified. The transmission conditions in these experiments were - Mediaddress Documents of noise, and for each iteration of the learning task only half of the possible 27 signifier/signified pairs were presented to participants. Under this kind of transmission bottleneck a high degree of sign/signified structure emerged. A plausible interpretation of these results Ideas Low-maintenance Landscape that the developing structure of the collection of signs is a consequence of the repeated forced inference by participants from 14 signs and signifieds in the training set to the entire set of 27 pairs. A moral could be that iterated forced prediction of the sign/signified pairs in the entire set, on the basis of exposure to only about half of them, induced the development of a systematic, compositional structure over the course of transmission. It is reasonable to conjecture that this resulting structure reflects effects of human memory, not a domain-specific language module—although further work would be required to rule out many other our common Inaugurat “As reject safety our and we ideals.” our between defense, false for as the. hypotheses. Thus Kirby and his colleagues focus on something very different from the prerequisites for language emergence. Linguistic nativists have been interested in how primates like us could have become Questionnaire Instructor of acquiring systems with the structural properties of natural languages. Kirby and his colleagues (while not denying that human cognitive evolution is of interest) are studying how languages evolve to be capable of being acquired by primates like us .
