Statistical learning is often taken to lie at the heart of many cognitive tasks, including the acquisition of language. One particular task in which probabilistic models have achieved considerable success is the segmentation of speech into words. However, these models have mostly been tested against English data, and as a result little is known about how a statistical learning mechanism copes with input regularities that arise from the structural properties of different languages. This study focuses on statistical word segmentation in (...) Arabic, a Semitic language in which words are built around consonantal roots. We hypothesize that segmentation in such languages is facilitated by tracking consonant distributions independently from intervening vowels. Previous studies have shown that human learners can track consonant probabilities across intervening vowels in artificial languages, but it is unknown to what extent this ability would be beneficial in the segmentation of natural language. We assessed the performance of a Bayesian segmentation model on English and Arabic, comparing consonant-only representations with full representations. In addition, we examined to what extent structurally different proto-lexicons reflect adult language. The results suggest that for a child learning a Semitic language, separating consonants from vowels is beneficial for segmentation. These findings indicate that probabilistic models require appropriate linguistic representations in order to effectively meet the challenges of language acquisition. (shrink)

We investigate a possible universal constraint on spatial meaning. It has been proposed that people attend preferentially to the endpoints of spatial motion events, and that languages may therefore make finer semantic distinctions at event endpoints than at event beginnings. We test this proposal. In Experiment 1, we show that people discriminate the endpoints of spatial motion events more readily than they do event beginnings—suggesting a non-linguistic attentional bias toward endpoints. In Experiment 2, speakers of Arabic, Chinese, and English (...) each described a set of spatial events displayed in video clips. Although the spatial systems of these languages differ, speakers of all three languages made finer semantic distinctions at event endpoints, compared to event beginnings. These findings are consistent with the proposal that event endpoints are privileged over event beginnings, in both language and perception. (shrink)

Harmonic Grammar (HG) and Optimality Theory (OT) are closely related formal frameworks for the study of language. In both, the structure of a given language is determined by the relative strengths of a set of constraints. They differ in how these strengths are represented: as numerical weights (HG) or as ranks (OT). Weighted constraints have advantages for the construction of accounts of language learning and other cognitive processes, partly because they allow for the adaptation of connectionist and statistical (...) models. HG has been little studied in generative linguistics, however, largely due to influential claims that weighted constraints make incorrect predictions about the typology of natural languages, predictions that are not shared by the more popular OT. This paper makes the case that HG is in fact a promising framework for typological research, and reviews and extends the existing arguments for weighted over ranked constraints. (shrink)

An English double-embedded relative clause from which the middle verb is omitted can often be processed more easily than its grammatical counterpart, a phenomenon known as the grammaticality illusion. This effect has been found to be reversed in German, suggesting that the illusion is language specific rather than a consequence of universal working memory constraints. We present results from three self-paced reading experiments which show that Dutch native speakers also do not show the grammaticality illusion in Dutch, whereas both (...) German and Dutch native speakers do show the illusion when reading English sentences. These findings provide evidence against working memory constraints as an explanation for the observed effect in English. We propose an alternative account based on the statistical patterns of the languages involved. In support of this alternative, a single recurrent neural network model that is trained on both Dutch and English sentences is shown to predict the cross-linguistic difference in the grammaticality effect.

LikeI thinkin English,(eu) acho quein Brazilian Portuguese can function as a discourse marker (DM) with more than one meaning, and these meanings are curiously diametrically opposed. Certainty, doubt or uncertainty is inferred by hearers in an interactional context. In a sample of audio-video recorded interviews, the occurrences of this DM were classified by meaning, and association tests between meanings and linguistic factors (pronoun realization, polarity, position in utterance), real-world features (type of evidence from which the speaker says something, and (...) discursive topic), prosody (F0, intensity and duration), and facial expressions were carried out. Differences that distinguish these factors were identified among certainty, doubt and uncertainty uses. The certainty meaning of(eu) acho quewas associated with pronoun presence, more formality and topics in which the speaker had direct evidence. Uncertainty and doubt were associated with pronoun absence, less formality and topics in which the speaker did not have direct evidence. Patterns of intensity and duration acted to distinguish the certainty, doubt and uncertainty meanings of(eu) acho que. In a conditional decision tree, the position in utterance, presence of a pronoun, type of speaker’s evidence, discursive topic, and duration helped to disambiguate the meanings of(eu) acho que. These results suggest the relevance of a multilevel approach to describe DM, in different languages, at least with respect to mental state verbs. (shrink)

According to classical arguments, language learning is both facilitated and constrained by cognitive biases. These biases are reflected in linguistic typology—the distribution of linguistic patterns across the world's languages—and can be probed with artificial grammar experiments on child and adult learners. Beginning with a widely successful approach to typology (Optimality Theory), and adapting techniques from computational approaches to statistical learning, we develop a Bayesian model of cognitive biases and show that it accounts for the detailed pattern of results (...) of artificial grammar experiments on noun-phrase word order (Culbertson, Smolensky, & Legendre, 2012). Our proposal has several novel properties that distinguish it from prior work in the domains of linguistic theory, computational cognitive science, and machine learning. This study illustrates how ideas from these domains can be synthesized into a model of language learning in which biases range in strength from hard (absolute) to soft (statistical), and in which language-specific and domain-general biases combine to account for data from the macro-level scale of typological distribution to the micro-level scale of learning by individuals.

The language game approach has recently been adopted to explore the conventionalization of linguistic knowledge in a social environment. Most contemporary studies focus on the dynamics of language games in random or predefined social networks, but neglect the reverse roles of communicative constraints in language evolution and social structures. This article, based on two forms of language games , examines whether a simple, distance-based communicative constraint can affect the conventionalization of linguistic knowledge. The study bridges the gap (...) between random networks and complex social structures, and illustrates that the internal properties of language games can influence the effects of communicative constraints and social structures.

The prominence of judgment data in contemporary linguistics is crucially tied to Chomsky's mentalist reconception of the field. Judgment data are meta‐linguistic judgments – judgments about specific linguistic items, construed broadly to include language‐like items (e.g. ungrammatical strings). A judgment of unacceptability provides stronger evidence of ungrammaticality – insofar as reasonable alternative explanations can be ruled out (pragmatic oddity, processing difficulties, memory constraints, lexical awkwardness, etc.). The use of judgment data has never been without critics. The objections (...) have taken various forms. Earlier objections tended to deem judgments problematic as evidence per se, not just in linguistics but more generally. Later objections contend that the use of judgment data is problematic more specifically in the linguistic domain, in some cases on account of how they are in fact typically gathered or because of an over‐reliance on them over other sources of evidence. Judgment data, no matter how collected, have a definite future in linguistics. (shrink)

Evidence is presented to show that the role of a generative grammar of a natural language is not merely to generate the grammatical sentences of that language, but also to relate them to their logical forms. The notion of logical form is to be made sense of in terms a natural logic, a logical for natural language, whose goals are to express all concepts capable of being expressed in natural language, to characterize all the valid inferences that can be made (...) in natural language, and to mesh with adequate linguistic descriptions of all natural languages. The latter requirement imposes empirical linguistic constraints on natural logic. A number of examples are discussed. (shrink)

The roles of linguistic, cognitive, and social-pragmatic processes in word learning are well established. If statistical mechanisms also contribute to word learning, they must interact with these processes; however, there exists little evidence for such mechanistic synergy. Adults use co-occurrence statistics to encode speech–object pairings with detailed sensitivity in stochastic learning environments (Vouloumanos, 2008). Here, we replicate this statistical work with nonspeech sounds and compare the results with the previous speech studies to examine whether exclusion constraints contribute equally (...) to the statistical learning of speech–object and nonspeech–object associations. In environments in which performance could benefit from exclusion, we find a learning advantage for speech over nonspeech, revealing an interaction between statistical and exclusion processes in associative word learning.

The complex characteristics of lexical blending have long troubled mainstream word formation research to the extent that it has typically been considered a peripheral issue in linguistics. In recent years this has begun to change, and there is currently a growing body of evidence uncovering the intriguing nature of this word formation process. In the present study, underlying principles and usage-based aspects of lexical blends were examined. Analyses of derivatives of three matrix words,republican, liberal, andvegetarian, revealed the impact of three (...) cognitive constraints on the use of lexical blends: schema transfer effects, neighborhood effects, and effects of the influence from morphological lexicalization. The first constraint fueled blend formation, while the other two displayed a hampering effect on the use of lexical blending. Furthermore, a study of the word class distribution in the datasets showed that there were significant differences in the grammar of lexical blending and compounding, respectively. (shrink)

Domain constraint, the requirement that analogues be selected from "the same category," inheres in the popular saying "you can't compare apples and oranges" and the textbook principle "the greater the number of shared properties, the stronger the argument from analogy." I identify roles of domains in biological, linguistic, and legal analogy, supporting the account of law with a computer word search of judicial decisions. I argue that the category treatments within these disciplines cannot be exported to general informal logic, (...) where the relevance of properties, not their number, must be the logically prior criterion for evaluating analogical arguments.

In this paper we compare grammatical inference in the context of simple and of mixed Lambek systems. Simple Lambek systems are obtained by taking the logic of residuation for a family of multiplicative connectives /, *, \, together with a package of structural postulates characterizing the resource management properties of the * connective. Different choices for Associativity and Commutativity yield the familiar logics NL, L, NLP, LP. Semantically, a simple Lambek system is a unimodal logic: the connectives get a Kripke (...) style interpretation in terms of a single ternary accessibility relation modeling the notion of linguistic composition for each individual system.The simple systems each have their virtues in linguistic analysis. But none of them in isolation provides a basis for a full theory of grammar. In the second part of the paper, we consider two types of mixed Lambek systems.The first type is obtained by combining a number of unimodal systems into one multimodal logic. The combined multimodal logic is set up in such a way that the individual resource management properties of the constituting logics are preserved. But the inferential capacity of the mixed logic is greater than the sum of its component parts through the addition of interaction postulates, together with the corresponding interpretive constraints on frames, regulating the communication between the component logics.The second type of mixed system is obtained by generalizing the residuation scheme for binary connectives to families of n-ary connectives, and by putting together families, of different arities in one logic. We focus on residuation for unary connectives, hence on mixed frames, as these already represent the complexities in full. We prove a number of elementary logical results for unary families of residuated connectives and their combination with binary families. The existing proposals for unary ‘structural modalities’ are situated within this general framework, and a number of new linguistic applications is given. (shrink)

This volume of new work by prominent phonologists goes to the heart of current debates in phonological and linguistic theory: should the explanation of phonological variety be constraint or rule-based and, in the light of the resolution of this question, how in the mind does phonology interface with other components of the grammar. The book includes contributions from leading proponents of both sides of the argument and an extensive introduction setting out the history, nature, and more general linguistic (...) implications of current phonological theory.

We revisit a typological puzzle due to Horn (Doctoral Dissertation, UCLA, 1972) regarding the lexicalization of logical operators: in instantiations of the traditional square of opposition across categories and languages, the O corner, corresponding to ‘nand’ (= not and), ‘nevery’ (= not every), etc., is never lexicalized. We discuss Horn’s proposal, which involves the interaction of two economy conditions, one that relies on scalar implicatures and one that relies on markedness. We observe that in order to express markedness and to (...) account for a bigger typological puzzle, namely the absence of lexicalizations of ‘XOR’ (= exclusive or), ‘all-or-none’, and many other imaginable logical operators, one must restrict the basic lexicalizable elements to a small set of primitives. We suggest that an ordering based perspective, following Keenan and Faltz (Boolean semantics for natural language, 1985), makes the stipulated primitives that we arrive at more natural. We also propose a modification to Horn’s proposal, based on recent work on implicatures, in which only the implicature condition is operative and in which markedness is part of the definition of the alternatives for scalar implicatures rather than an independent condition.

This book focuses on binomials (word pairs such as heart and soul, rich and poor, or if and when), and in particular on the degree of reversibility that English binomials demonstrate. Detailed and innovative corpus linguistic analyses investigate the correlates of the degree of reversibility, linguistic constraints that influence the ordering and reversibility of binomials and the diachronic development of reversibility. In addition, judgment data are analyzed for their convergence and divergence with corpus data regarding degrees of (...) reversibility. The book thus establishes reversibility as a complex characteristic of the binomial construction, at the same time throwing light on general questions in phraseology, lexicalization, language structure and language processing.

For half a century the idea of rational thought has been challenged by discoveries that call into question some of its foundations. How we actually think seems to be at odds with descriptive and prescriptive models that once held sway in the development of modern science and scholarship.

Another—the one on display in Rationality: Contexts and Constraints—is an active attempt to revise those models, so as to enhance their (...) compatibility with new discoveries, in a maximally coherent and inclusive way.

How semiotic freedom emerges in the evolution and development of organisms through semiotic scaffolding is a core problem for biosemiotics. There is a paradox in explaining this semiotic emergence: reduction in (semiotic) freedom leads to the creation of new semiotic freedom. Semiotic emergence is a species of dynamic emergence. Accordingly, the paradox of semiotic emergence is a species of the paradox of dynamic emergence. The latter paradox claims that reducing lower-level freedom generates new freedom at a higher level. The solution (...) to the paradox lies in clarifying the ambiguity in the term freedom. The conceptual inconsistency in the paradox comes from confusing two types of freedom. One type of freedom means the possibility a system could have, while the other refers to the capacity of a system to access a specific (range of) state(s). There is an inverse relation between the two types of freedom. With the clarification, the conceptual inconsistency is explained away. This understanding of semiotic emergence may help us further understand core ideas in biosemiotics and provide a conceptual foundation for empirical studies of biosemiotics. (shrink)

In this target article the following hypotheses are discussed: (1) Colour is autonomous: a perceptuolinguistic and behavioural universal. (2) It is completely described by three independent attributes: hue, brightness, and saturation: (3) Phenomenologically and psychophysically there are four unique hues: red, green, blue, and yellow; (4) The unique hues are underpinned by two opponent psychophysical and/or neuronal channels: red/green, blue/yellow. The relevant literature is reviewed. We conclude: (i) Psychophysics and neurophysiology fail to set nontrivial constraints on colour categorization. (ii) (...) Linguistic evidence provides no grounds for the universality of basic colour categories. (iii) Neither the opponent hues red/green, blue/yellow nor hue, brightness, and saturation are intrinsic to a universal concept of colour. (iv) Colour is not autonomous. (shrink)

Normative political theorists working in the field of linguistic justice generally believe that participation in democratic life in linguistically diverse societies requires a shared lingua franca (e.g., Patten 2009; Van Parijs 2011). Even when a shared lingua franca is present, however, there is likely to be a variety of ways in which people speak it, due to variations in accent, pitch, register, and lexicon. This paper examines the implications of intra‐linguistic diversity for democracy and political representation. More specifically, (...) by drawing on Andrew Rehfeld's (2010) work and on relevant sociolinguistics research, the paper argues that widespread unconscious linguistic prejudice constitutes a constraint on some citizens' right to run for political office that is incompatible with democratic equality. The argument is illustrated via a number of examples concerning Australian politicians. (shrink)

Establishing and maintaining mutual understanding in everyday conversations is crucial. To do so, people employ a variety of conversational devices, such as backchannels, repair, and linguistic entrainment. Here, we explore whether the use of conversational devices might be influenced by cross‐linguistic differences in the speakers’ native language, comparing two matched languages—Danish and Norwegian—differing primarily in their sound structure, with Danish being more opaque, that is, less acoustically distinguished. Across systematically manipulated conversational contexts, we find that processes supporting mutual (...) understanding in conversations vary with external constraints: across different contexts and, crucially, across languages. In accord with our predictions, linguistic entrainment was overall higher in Danish than in Norwegian, while backchannels and repairs presented a more nuanced pattern. These findings are compatible with the hypothesis that native speakers of Danish may compensate for its opaque sound structure by adopting a top‐down strategy of building more conversational redundancy through entrainment, which also might reduce the need for repairs. These results suggest that linguistic differences might be met by systematic changes in language processing and use. This paves the way for further cross‐linguistic investigations and critical assessment of the interplay between cultural and linguistic factors on the one hand and conversational dynamics on the other.

Taboo terms offer a playground for linguistic creativity in language after language, and sign languages form no exception. The present paper offers the first investigation of taboo terms in sign languages from a cognitive linguistic perspective. We analyze the linguistic mechanisms that introduce offense, focusing on the combined effects of cognitive metonymy and iconicity. Using the Think Aloud Protocol, we elicited offensive or crass signs and dysphemisms from nine signers. We find that German Sign Language uses a (...) variety of linguistic means to introduce and enhance offense, many of which rely on iconic properties of the taboo sign. In conjunction with cross-linguistically common metonymic word-formation strategies, the degree of visual explicitness of a sign increases its potential to offend. Semantically similar taboo signs based on the same metonymic anchor but differing in their degree of iconicity also differ in offensiveness. This allows for creating dysphemisms and euphemisms via phonological changes to a sign. We further show that embodiment creates modality-enhanced ‘vicarious embarrassment’ in the viewer that results in the respective signs being judged obscene or offensive. Further, lexical blending and non-manual enhancement play a role in the creation of dysphemisms in DGS. Lastly, we propose that iconicity as a cognitive structuring principle of linguistic expressions constrains the possible semantic extensions of iconic taboo terms. (shrink)

Does the proper pursuit of cognitive science necessitate a devaluation of the ostensible phenomenon of linguistically framed conceptual thought? Paul Churchland has asserted the necessity of such devaluation forthrightly, and others have shown varying degrees of inclination in this direction.

We found a direct relationship between variation in informants' grammaticality intuitions about pronoun coreference and variation in the same informants' use of a clause segmentation strategy during sentence perception. It has been proproposed that ‘c‐command’, a structural principle defined in terms of constituent dominance relations, constrains within‐sentence coreference between pronouns and noun antecedents. The relative height of the pronoun and the noun in the phrase structure hierarchy determines whether the c‐command constraint blocks coreference: Coreference is allowed only when the complement (...) structure containing the noun is attached higher than the pronoun. We collected informants' judgments on pronoun‐noun coreference in which the noun antecedent was contained in a complement structure dominated by either the Sentence‐node (S‐node) (higher than the pronoun) or the Verb‐phrase‐node (VP‐node) (not higher than the pronoun). We also assessed each informant's perceptual clause‐closure tendency using an auditory word‐monitor paradigm. Informants who strongly segmented clauses in the perceptual task did not differentiate between an S‐ and VP‐attachment of sentence complements, as revealed in their coreference judgments, but rather appeared to attach all sentence complements to the S‐node. Informants with relatively weak perceptual segmentation differentiated their coreference judgments according to the node attachment of the complement structure. These results indicate that the linguistic universal controlling within‐sentence coreference applies to the perceptually available structure for a sequence, not to its pure linguistic structure. Hence, linguistic intuitions result from the interaction of three independent faculties: language‐specific knowledge, perceptual processes, and linguistic universals. (shrink)

“Scalar implicatures” is a phrase used to refer to some inferences arising from the competition between alternatives: typically, “Mary read some of the books” ends up conveying that Mary did not read all books, because one could have said “Mary read all books”.

Connectedness is a sister notion of monotonicity, which has been recruited to explain certain lexical restrictions on nouns, adjectives and more recently quantifiers; we propose here that connectedness could play a similar role at the level of propositional meanings.

Objects and substances bear fundamentally different ontologies. In this article, we examine the relations between language, the ontological distinction with respect to individuation, and the world. Specifically, in cross‐linguistic developmental studies that followImai and Gentner (1997), we examine the question of whether language influences our thought in different forms, like (1) whether the language‐specific construal of entities found in a word extension context (Imai & Gentner, 1997) is also found in a nonlinguistic classification context; (2) whether the presence of (...) labelsper se, independent of the count‐mass syntax, fosters ontology‐based classification; (3) in what way, if at all, the count‐mass syntax that accompanies a label changes English speakers' default construal of a given entity?On the basis of the results, we argue that the ontological distinction concerning individuation is universally shared and functions as a constraint on early learning of words. At the same time, language influences one's construal of entities cross‐lingistically and developmentally, and causes a temporary change of construal within a single language. We provide a detailed discussion of how each of these three ways language may affect the construal of entities, and discuss how our universally possessed knowledge interacts with language both within a single language and in cross‐linguistic context.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.2 (2003) 161-167 [Access article in PDF] Social, Cognitive, and Neural Constraints on Subjectivity and Agency:Implications for Dissociative Identity Disorder Peter Q. Deeley In this commentary, I consider Matthew's argument after making some general observations about dissociative identity disorder (DID). In contrast to Matthew's statement that "cases of DID, although not science fiction, are extraordinary" (p. 148), I believe that there are natural analogs (...) of the disorder that, when considered, make it seem less puzzling and exotic. After discussing these examples, I examine the relations between social, cognitive, and neural processes supporting subjectivity and agency, to identify sources of personal identity in cases of DID that can be used as a basis for assessing Matthew's points against Behnke and Sinnott-Armstrong. I am not proposing a comprehensive theory, but rather identifying what I believe are components of such a theory. I then outline an approach to determining criminal responsibility in DID, drawing on analogies with other psychiatric disorders. Dissociative Identity Disorder DID is a disorder described in DSM-IV, which "is characterised by the presence of two or more distinct identities or personality states that recurrently take control of the individual's behaviour accompanied by an inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness" (American Psychiatric Association, p. 519). Recognizing Personal Identity How is personal identity recognized in normal cognition? If we take personhood to involve recognition of continuity of social, psychological, and physical identity for a given individual, then such judgments are routinely made rapidly and automatically as an aspect of what has come to be termed social cognition (Adolphs 2003). There is likely to be considerable redundancy in [End Page 161] the types of information used to make judgments about whether a person is the same as one who was previously encountered, or perhaps heard about—for example, facial features, movement patterns, speech prosody, dress, speech content, gender, ethnicity, social role, among other features, all provide information about individual identity, and hence personhood. When uncertainty exists, it is likely to reflect a loss or alteration of cues that would ordinarily be used in a rapid, automatic, unexamined way (Adolphs 2003). In such extreme cases (for example, severe mental illness or disfigurement), the problem of identification becomes the subject of explicit reasoning (and hence of potential disagreement, because we then engage in post hoc rationalizations to establish criteria for determining personhood, whereas normally we rely on essentially automatic, implicit abilities that work in most circumstances, some of which make little use of linguistic representations and formal reasoning—for example, individual facial identity recognition, which may occur as quickly as 170 ms after stimulus onset [Adolphs 2003]). Nevertheless, examining our judgments and intuitions in cases that force us to explicitly consider whether personal identity is preserved may provide analogies and clues for how we should proceed with DID. Let us consider, then, some natural analogs of DID. Natural Analogs of DID Method Acting I suggest that method acting is an analog of DID (Manderino 1985). Method acting refers to an approach to acting training and performance in which emphasis is placed on intensely imagining and identifying with the mental life of the character being portrayed. Training courses and manuals list many techniques and practices that can be used to facilitate absorption in a role, drawing on different kinds of memory—for example, experiential memories, memories of others, general knowledge (semantic memory), and memories of sensations and feelings, to creative a vivid sense of the subjective experience and actions of the character. Manderino, a method acting teacher, comments: "it is important to investigate the way in which your own mental makeup can improperly influence a character. Insecurities, self-consciousness, shyness or self-doubts can maintain a strong hold, and permitting any of these feelings to enter a performance is to remain the actor and not enter into the mental life of the character. For some, acting allows personal problems to be left behind, and they are thankful for the complete escape that... (shrink)

The thesis examines a central and controversial question in the philosophy of mind and language: Is meaning normative? Are there rules we must follow for our words to have meaning? ;Philosophers are sharply divided over this question. One side, often associated with Wittgenstein and more recently Kripke, sees meaning as essentially normative. If a sign is to be meaningful, then surely, it is argued, there must be a distinction between the correct and incorrect use of that sign. The other side (...) eschews the appeal to rules. This line of thought goes back to Quine, and has been vigorously defended by Davidson, who argues that linguistic rules are no more essential to speaking a language than the rules of etiquette at a dinner table are to consuming food. ;The dissertation proposes that we approach the question by asking whether there is a notion of linguistic incorrectness which is essential to meaning. Various common versions of the notion of linguistic incorrectness are considered, including the one appealed to by Saul Kripke in his discussion of Wittgenstein, the suggestion that going against the communicative conventions is making a linguistic error, and Tyler Burge's idea that we err when we violate certain constitutive community norms. Neither of these suggestions, it is argued, supports the idea that rules are essential to meaning. ;But we should not conclude from this, as does Davidson, that we can reject the notion of linguistic incorrectness altogether. If a speaker is to be interpretable there must be certain constraints on her linguistic use, and a plausible construal of these constraints, it is argued, presupposes a notion of linguistic incorrectness. The conclusion is that there is a notion of linguistic incorrectness which is essential to meaning, although this notion is not to be understood along the ordinary lines. (shrink)

How linguistic structures evolve so as to become easier to process is addressed by Isbilen and Christiansen for the Now‐or‐Never bottleneck. The authors suggest that this fundamental challenge in language processing is coped with by rapid compression of the transient linguistic input into chunks then to be passed on. As linguistic structures that can be chunked more easily tend to stabilize and proliferate, language evolves to fit learners’ cognitive capabilities.

Several philosophers have argued that ‘constraints’ constrain (and thereby explain) by virtue of being modally stronger than ordinary laws of nature. In this way, a constraint applies to all possible systems, for a variety of possibility that is broader (that is, more inclusive) than the variety we employ when we say that the ordinary laws of nature apply to all physically possible systems. Explanations by constraint are thus more broadly unifying than ordinary causal explanations. Philosophical examples of good candidates (...) for constraints have heretofore been drawn almost exclusively from fundamental physics. This paper argues for the existence of such constraints (even multiple levels of them) in at least one human science (linguistics), not just in physics. (shrink)
