Some nonlinguistic systems of representation display some of the six features of a language-of-thought (LoT) delineated by Quilty-Dunn et al. But they conjecture something stronger: That all six features cooccur homeostatically in nonlinguistic thought. Here I argue that there is no good evidence for nonlinguistic deductive reasoning involving the disjunctive syllogism. Animals and prelinguistic children probably do not make logical inferences.

I argue that at least some nonlinguistic animals have conceptual capabilities. First, I show that positions that take linguistic capabilities to be necessary for conceptual capabilities are unable to explain the possibility of concept acquisition. Second, I argue that awareness of abstract relations requires conceptual capabilities and success at relational matching-to-sample tasks requires awareness of the abstract relations of same and different. Crows and amazons are able to succeed at relational matching-to-sample tasks, so we should attribute conceptual capabilities to (...) them. Third, I argue that at least some nonlinguistic animals are able to have and present reasons by making and having explicit content. Fourth, I argue for an externalist account of inference that takes epistemic responsibility to be a deontic status. Fifth, and finally, I argue that at least some nonlinguistic animals should be regarded as living in normative communities because their communications meet the conditions for assertions. (shrink)

Grodzinsky's characterization of the syntactic function of Broca's area is convincing, but his argument that this transformation processing capability is specific to language is less so. Based on predictions from simulation studies of sequence learning, we report a correlation between agrammatic patients' impairments in (a) syntactic comprehension, and (b) nonlinguistic sequence transformation processing, indicating the existence of a nonlinguistic correlate of agrammatic aphasia.

While it is philosophically contested whether nonlinguistic animals can have conceptual capabilities, it is also philosophically contested whether one can even empirically test for such capabilities. I draw from Sellars’ work on psychological nominalism to develop an empirically tractable means of distinguishing between tasks that require conceptual capabilities and those that do not. Tasks that require conceptual capabilities are those that require awareness of abstract relations, whereas tasks that can be solved merely through Sellarsian picturing do not. I argue (...) that relational matching-to-sample tasks cannot be solved through picturing and therefore require awareness of the abstract relations of same and different. Crows and amazons have both been able to succeed at relational matching-to-sample tasks; therefore, there are at least some nonlinguistic animals that have conceptual capabilities. Finally, I consider the objection that one cannot attribute conceptual capabilities without also attributing knowledge, and Sellarsian conditions for knowledge are beyond the capabilities of any nonlinguistic animal. In response, I argue that Sellarsian conditions for knowledge only require an implicit grasp of the is/looks distinction and empirical work with chimpanzees on their understanding of the appearance/reality distinction demonstrates that they can meet this standard. Therefore, language is not necessary for meeting Sellarsian conditions for knowledge. (shrink)

This document describes my dissertation proposal, “Aspect, plurality and quantification”, for a nonlinguist audience for the purposes of Penn’s SAS Dissertation Completion Fellowship. The dissertation proposal is available online on my website, http://www.ling.upenn.edu/~champoll/, as well as a handout with a description targeted at a linguist audience.

What is the role of language in constructing knowledge? In this article, we ask whether learning new relational language can create new ways of thinking. In Experiment 1, we taught English speakers to talk about time using new vertical linguistic metaphors, saying things like “breakfast is above dinner” or “breakfast is below dinner”. In Experiment 2, rather than teaching people new metaphors, we relied on the left–right representations of time that our American college student participants have already internalized through a (...) lifetime of visuospatial experience reading and writing text from left to right. In both experiments, we asked whether the representations are susceptible to verbal interference. We found that learning new metaphors created new space–time associations that could be detected in a nonlinguistic implicit association task; these newly learned representations were not susceptible to verbal interference; and with respect to both verbal and visual interference, representations newly learned from linguistic metaphor behaved just like those on the left–right axis that our participants had acquired through years of visuospatial experience. Taken together, these results suggest that learning new relational language can be a powerful tool in constructing new representations and expanding our cognitive repertoire. (shrink)

Across cultures people construct spatial representations of time. However, the particular spatial layouts created to represent time may differ across cultures. This paper examines whether people automatically access and use culturally specific spatial representations when reasoning about time. In Experiment 1, we asked Hebrew and English speakers to arrange pictures depicting temporal sequences of natural events, and to point to the hypothesized location of events relative to a reference point. In both tasks, English speakers (who read left to right) arranged (...) temporal sequences to progress from left to right, whereas Hebrew speakers (who read right to left) arranged them from right to left, replicating previous work. In Experiments 2 and 3, we asked the participants to make rapid temporal order judgments about pairs of pictures presented one after the other (i.e., to decide whether the second picture showed a conceptually earlier or later time-point of an event than the first picture). Participants made responses using two adjacent keyboard keys. English speakers were faster to make “earlier” judgments when the “earlier” response needed to be made with the left response key than with the right response key. Hebrew speakers showed exactly the reverse pattern. Asking participants to use a space-time mapping inconsistent with the one suggested by writing direction in their language created interference, suggesting that participants were automatically creating writing-direction consistent spatial representations in the course of their normal temporal reasoning. It appears that people automatically access culturally specific spatial representations when making temporal judgments even in nonlinguistic tasks. (shrink)

This chapter explores how a semantics can be provided for nonlinguistic thoughts in a way that both does justice to philosophical constraints on acceptable theories of content and provides the ethologist or developmental psychologist with a workable method of assigning content to the beliefs and desires of nonlinguistic creatures. The utility condition of a belief is a state of affairs construable in purely extensional terms. Determining an ontology can be no more than the first stage in resolving the (...) problem of indeterminacy. A single state of affairs can be apprehended by a creature in many different ways, and in order to explain how its representations of the environment cause it to behave in the way it does, one can specify not simply the state of affairs it is representing but also how it apprehends that state of affairs.

This chapter considers a deflationary or minimalist construal of the nature of nonlinguistic thought that might be deployed to finesse the apparent need to attribute thoughts to creatures that are not language-users. The aim of the minimalist proposal is to show that thinking behavior in nonlinguistic creatures can be understood in nonpropositional and perceptual terms, rather than through the attribution of propositional attitudes such as beliefs and desires. In opposition to this the book suggest that there are important (...) types of nonlinguistic thought that cannot be accommodated in the manner proposed by the minimalists. The requirements of psychological explanation often demand that we attribute to nonlinguistic creatures thoughts that are structured, represent the world in a highly determinate way, and reflect the particular mode of presentation under which the creature apprehends its environment.

From Fodor and Pylyshyn’s celebrated 1988 systematicity argument in favour of a language of thought , a challenge to connectionist models arises in the form of a dilemma: either these models do not explain systematicity or they are implementations of LOT. From consideration of this challenge and of systematicity in domains other than language, defenders of connectionism have mounted a parallel systematicity argument against LOT which results in a new self-defeating dilemma, what I call here the systematicity challenge challenge : (...) either LOT does not explain nonlinguistic systematicity, or it is in no better position than its rivals to explain any systematicity, even linguistic systematicity. In this paper, first, I critically examine the SCC and some considerations that seem to support it. Second, I offer a response to the SCC by: showing that LOT was never meant to be a cognitive model restricted only to linguistic systematicity, and formulating a new argument in favour of LOT from nonlinguistic systematicity. Third, I argue that there is a central assumption underlying the SCC and maintain that it is mistaken. I conclude that the classical systematicity challenge continues to be fully valid for linguistic and nonlinguistic domains. (shrink)

This chapter explains how a theorist might fix an ontology in a way that will allow the theorist to determine what objects a particular non-language-using creature is capable of thinking about—or, in other words, that will elucidate how the creature “carves up” its world into bounded individuals. Among other issues, it explores a version of successful semantics based on the idea that the content of a belief is its utility condition and the content of a desire its satisfaction-condition. Existing versions (...) of success semantics generate a significant problem of indeterminacy. Success semantics originated with some fleeting comments by Frank Ramsey about the beliefs of a chicken in his 1927 article ‘Facts and Propositions’. He commented that the chicken's belief that a certain type of caterpillar is poisonous should be equated with the chicken's abstaining from eating such caterpillars on account of unpleasant experiences connected with them.

This paper considers the question whether the Scottish philosopher Mary Shepherd (1777–1847) endorses a form of nonconceptualism about mental states or their content. While the paper does not arrive at a definitive answer to the question, it paves the way to answering it in the future by demonstrating that there are prima facie promising ways to relate Shepherd to either of the previously mentioned forms of nonconceptualism – although I tentatively conclude that, ultimately, it will be more profitable to consider (...) her views in the context of content nonconceptualism. In arguing the way it does, this paper, then, also aims to bridge the often-lamented gap between the history of philosophy and our contemporary debates. (shrink)

The central concern of this article is whether the semantic approach has the resources to appropriately capture the core tenets of structural realism. Chakravartty (2001) has argued that a realist notion of correspondence cannot be accommodated without introducing a linguistic component, which undermines the approach itself. We suggest that this worry can be addressed by an appropriate understanding of the role of language in this context. The real challenge, however, is how to incorporate the core notion of `explanatory approximate truth' (...) in such a way that the emphasis on structure is retained. (shrink)

Adults and children spontaneously produce gestures while they speak, and such gestures appear to support and expand on the information communicated by the verbal channel. Little research, however, has been carried out to examine the role played by gesture in the listener's representation of accumulating information. Do listeners attend to the gestures that accompany narrative speech? In what kinds of relationships between gesture and speech do listeners attend to the gestural channel? If listeners do attend to information received in gesture, (...) how is this information represented— is it 'tagged' as originating in the gestural channel? In this article research is described that addresses these questions. Results show that listeners do attend to information conveyed in gesture, when that information supplements or even contradicts the information conveyed by speech. And information received via gesture is available for retelling in speech. These results are taken to demonstrate that gesture is not taken by the listener to be epiphenomenal to the act of speaking, or a simple manual translation of speech. But they also suggest that the information conveyed in a discourse may be represented in a manner that is neither gesture nor language, although accessible to both channels. (shrink)

A central debate in the ethics of deception concerns the moral comparison among the three media through which deception is executed: lying, falsely implicating, or nonlinguistic deception. The two prominent views are that lying is morally worse or that the choice of medium is morally insignificant. This article refutes both and argues for a new position. The article first presents a theory on the moral significance of the medium of deception as such: it argues that the medium of communication (...) affects the reliability of beliefs formed through it, which amounts to gradations in the warrant of truth of different media. Breach of lower warrant of truth is a lesser breach of trust; it therefore deserves lighter condemnation. Consequently, the article shows that, morally speaking, lying is either worse than or equal to falsely implicating and that there is no a priori gradation between nonlinguistic deception and the two linguistic media.

This paper describes a method for extracting importance of slides in a lecture review system. We introduce "index of importance" to quantitatively evaluate importance of slides. The index of importance is subjective evaluation value that is attached to each slide by lecturers. Firstly, the lecture review system extracts the index of importance of the slide by using a multi-layer neural network. In a MLN learning process, eight types of nonlinguistic informations, such as the presentation time of the slide, are (...) used as inputs and the index of importance given by lecturers are set as outputs. Secondly, the index of importance is modified by using the other MLN which has two types of inputs; one is the index of importance and the other is similarities between the slide and adjacent slides. The similarities are calculated with key-word vectors extracted by linguistic informations in slides. The experimental results showed that the index of importance extracted by the system is highly correlated with the index attached by lecturers. As a result, the lecture review system with the proposed extraction method can properly detect key slides and helps students to learn the contents of a lecture effectively. (shrink)

Because we humans speak a public language, there has always been a special reason to suppose that we have a language of thought. For nonhuman animals, this special reason is missing, and the issue is less straightforward. On the one hand, there is evidence of various types of nonlinguistic representations, such as analog magnitude representations, which can explain many types of intelligent behavior. But on the other hand, the mere fact that some aspects of animal cognition can be explained (...) by nonlinguistic representations hardly suffices to show that animal minds are bereft of any sentence-like representations. This paper explores these complexities and argues that empirical research into the logical abilities of nonhuman animals provides a more direct way of evaluating whether they have a language of thought. Along the way, I offer a novel suggestion of how the hypothesis that animals draw disjunctive syllogisms can be empirically distinguished from the hypothesis, defended by Michael Rescorla, that animals reason probabilistically in accordance with Bayes’ Law.

Nonlinguistic signals in the voice and musical instruments play a critical role in communicating emotion. Although previous research suggests a common mechanism for emotion processing in music and speech, the precise relationship between the two domains is unclear due to the paucity of direct evidence. By applying the adaptation paradigm developed by Bestelmeyer, Rouger, DeBruine, and Belin [2010. Auditory adaptation in vocal affect perception. Cognition, 117, 217–223. doi:10.1016/j.cognition.2010.08.008], this study shows cross-domain aftereffects from vocal to musical sounds. Participants heard (...) an angry or fearful sound four times, followed by a test sound and judged whether the test sound was angry or fearful. Results show cross-domain aftereffects in one direction – vocal utterances to musical sounds, not vice-versa. This effect occurred primarily for angry vocal sounds. It is argued that there is a unidirectional relationship between vocal and musical sounds where emotion processing of vocal sounds encompasses musical sounds but not vice-versa. (shrink)

This essay argues that nonlinguistic animals qualify not just for externalist notions of rationality (maximizing biological fitness or utility), but also for internal ones. They can act for reasons in several senses: their behaviour is subject to intentional explanations, they can act in the light of reasonsprovided that the latter are conceived as objective facts rather than subjective mental statesand they can deliberate. Finally, even if they could not, it would still be misguided to maintain that animals are capable (...) only of (mechanical) behaviour, not of (intentional) action. (shrink)

The processing of emotional nonlinguistic information in speech is defined as emotional prosody. This auditory nonlinguistic information is essential in the decoding of social interactions and in our capacity to adapt and react adequately by taking into account contextual information. An integrated model is proposed at the functional and brain levels, encompassing 5 main systems that involve cortical and subcortical neural networks relevant for the processing of emotional prosody in its major dimensions, including perception and sound organization; related (...) action tendencies; and associated values that integrate complex social contexts and ambiguous situations.

Skeptics about nonlinguistic mindreading often use an inferential rule of thumb—the principle of conservatism—to cast doubt on purported empirical evidence of mindreading abilities in nonlinguistic creatures. This principle, if warranted, would seem to count generally against explanatory hypotheses that posit nonlinguistic mindreading, instead favoring mere behavior-reading hypotheses. Using a test case from research with chimpanzees, I show that this principle is best understood as an appeal to parsimony; that, regardless of how one conceives of parsimony, the principle (...) is unwarranted; and that, once we put the principle aside, the prospects for nonlinguistic mindreading are brighter than traditionally thought.

We identify a number of principles with respect to prediction that, we argue, underpin adult language comprehension: (a) comprehension consists in realizing a mapping between the unfolding sentence and the event representation corresponding to the real‐world event being described; (b) the realization of this mapping manifests as the ability to predict both how the language will unfold, and how the real‐world event would unfold if it were being experienced directly; (c) concurrent linguistic and nonlinguistic inputs, and the prior internal (...) states of the system, each drive the predictive process; (d) the representation of prior internal states across a representational substrate common to the linguistic and nonlinguistic domains enables the predictive process to operate over variable time frames and variable levels of representational abstraction. We review empirical data exemplifying the operation of these principles and discuss the relationship between prediction, event structure, thematic role assignment, and incrementality. (shrink)

In a continuation of the conversation with Fitch, Chomsky, and Hauser on the evolution of language, we examine their defense of the claim that the uniquely human, language-specific part of the language faculty (the “narrow language faculty”) consists only of recursion, and that this part cannot be considered an adaptation to communication. We argue that their characterization of the narrow language faculty is problematic for many reasons, including its dichotomization of cognitive capacities into those that are utterly unique and those (...) that are identical to nonlinguistic or nonhuman capacities, omitting capacities that may have been substantially modified during human evolution. We also question their dichotomy of the current utility versus original function of a trait, which omits traits that are adaptations for current use, and their dichotomy of humans and animals, which conflates similarity due to common function and similarity due to inheritance from a recent common ancestor. We show that recursion, though absent from other animals’ communications systems, is found in visual cognition, hence cannot be the sole evolutionary development that granted language to humans. Finally, we note that despite Fitch et al.’s denial, their view of language evolution is tied to Chomsky’s conception of language itself, which identifies combinatorial productivity with a core of “narrow syntax.” An alternative conception, in which combinatoriality is spread across words and constructions, has both empirical advantages and greater evolutionary plausibility. q 2005 Elsevier B.V.

Fundamental to spatial knowledge in all species are the representations underlying object recognition, object search, and navigation through space. But what sets humans apart from other species is our ability to express spatial experience through language. This target article explores the language ofobjectsandplaces, asking what geometric properties are preserved in the representations underlying object nouns and spatial prepositions in English. Evidence from these two aspects of language suggests there are significant differences in the geometric richness with which objects and places (...) are encoded. When an object is named (i.e., with count nouns), detailed geometric properties – principally the object's shape (axes, solid and hollow volumes, surfaces, and parts) – are represented. In contrast, when an object plays the role of either “figure” (located object) or “ground” (reference object) in a locational expression, only very coarse geometric object properties are represented, primarily the main axes. In addition, the spatial functions encoded by spatial prepositions tend to be nonmetric and relatively coarse, for example, “containment,” “contact,” “relative distance,” and “relative direction.” These properties are representative of other languages as well. The striking differences in the way language encodes objects versus places lead us to suggest two explanations: First, there is a tendency for languages to level out geometric detail from both object and place representations. Second, a nonlinguistic disparity between the representations of “what” and “where” underlies how language represents objects and places. The language of objects and places converges with and enriches our understanding of corresponding spatial representations. (shrink)

I argue that semantics is the study of the proprietary database of a centrally inaccessible and informationally encapsulated input–output system. This system’s role is to encode and decode partial and defeasible evidence of what speakers are saying. Since information about nonlinguistic context is therefore outside the purview of semantic processing, a sentence’s semantic value is not its content but a partial and defeasible constraint on what it can be used to say. I show how to translate this thesis into (...) a detailed compositional-semantic theory based on the influential framework of Heim and Kratzer. This approach situates semantics within an independently motivated account of human cognitive architecture and reveals the semantics–pragmatics interface to be grounded in the underlying interface between modular and central systems.

Philosophy and literature enjoy a close, complex relationship. Elucidating the connections between these two fields, this book examines the ways philosophy deploys literary means to advance its practice, particularly as a way of life that extends beyond literary forms and words into physical deeds, nonlinguistic expression, and subjective moods and feelings.

In this article, we analyze and reject two versions of the content‐argument against animal beliefs, namely, the ontological argument from Davidson and the epistemological argument from Stich. One of the main defects of the strongest version of the argument is that it over‐intellectualizes belief ascriptions in humans and thus sets the comparative bar for belief ascriptions in animals too high. In the second part of the article, we develop a gradualist notion of belief which captures basic beliefs as well as (...) Davidsonian linguistic beliefs, and we specify the conditions under which belief ascriptions to nonlinguistic animals are justified. (shrink)

We investigated the emergence of sociolinguistic indexicality using an artificial-language-learning paradigm. Sociolinguistic indexicality involves the association of linguistic variants with nonlinguistic social or contextual features. Any linguistic variant can acquire “constellations” of such indexical meanings, though they also exhibit an ordering, with first-order indices associated with particular speaker groups and higher-order indices targeting stereotypical attributes of those speakers. Much natural-language research has been conducted on this phenomenon, but little experimental work has focused on how indexicality emerges. Here, we present (...) three miniature artificial-language experiments designed to break ground on this question. Results show ready formation of first-order indexicality based on co-occurrence alone, with higher-order indexicality emerging as a result of extension to new speaker groups, modulated by the perceived practical importance of the indexed social feature.

The metatethical position known as motive internalism (MI) holds that moral beliefs are necessarily motivating. Adina Roskies (in Philosophical Psychology, 16) has recently argued against MI by citing patients with injuries to the ventromedial (VM) cortex as counterexamples to MI. Roskies claims that not only do these patients not act in accordance with their professed moral beliefs, they exhibit no physiological or affective evidence of being motivated by these beliefs. I argue that Roskies' attempt to falsify MI is unpersuasive because (...) the evidence used to attribute the relevant moral beliefs to VM patients is insufficient: Contra Roskies, that VM patients are proficient moral reasoners does not establish the presence of these moral beliefs. In addition, the linguistic evidence Roskies cites (a) is vulnerable to methodological worries about its reliability or authenticity, (b) does not override counterevidence derived from the patients' nonlinguistic behavior, and (c) is undermined by VM patients' inability to correctly attribute moral beliefs to others. I conclude with a proposal about how MI should be interpreted, given that it is not falsified by empirical evidence of the sort put forth by Roskies. (shrink)

This investigation examined whether speakers produce reliable prosodic correlates to meaning across semantic domains and whether listeners use these cues to derive word meaning from novel words. Speakers were asked to produce phrases in infant‐directed speech in which novel words were used to convey one of two meanings from a set of antonym pairs (e.g., big/small). Acoustic analyses revealed that some acoustic features were correlated with overall valence of the meaning. However, each word meaning also displayed a unique acoustic signature, (...) and semantically related meanings elicited similar acoustic profiles. In two perceptual tests, listeners either attempted to identify the novel words with a matching meaning dimension (picture pair) or with mismatched meaning dimensions. Listeners inferred the meaning of the novel words significantly more often when prosody matched the word meaning choices than when prosody mismatched. These findings suggest that speech contains reliable prosodic markers to word meaning and that listeners use these prosodic cues to differentiate meanings. That prosody is semantic suggests a reconceptualization of traditional distinctions between linguistic and nonlinguistic properties of spoken language. (shrink)

Dialog is a joint action at different levels. At the highest level, the goal of interlocutors is to align their mental representations. This emerges from joint activity at lower levels, both concerned with linguistic decisions (e.g., choice of words) and nonlinguistic processes (e.g., alignment of posture or speech rate). Because of the high‐level goal, the interlocutors are particularly concerned with close coupling at these lower levels. As we illustrate with examples, this means that imitation and entrainment are particularly pronounced (...) during interactive communication. We then argue that the mechanisms underlying such processes involve covert imitation of interlocutors’ communicative behavior, leading to emulation of their expected behavior. In other words, communication provides a very good example of predictive emulation, in a way that leads to successful joint activity. (shrink)

The tradition descending from Frege and Russell has typically treated theories of meaning either as theories of meanings, or as theories of truth conditions. However, propositions of the classical sort don't exist, and truth conditions can't provide all the information required by a theory of meaning. In this book, one of the world's leading philosophers of language offers a way out of this dilemma. Traditionally conceived, propositions are denizens of a "third realm" beyond mind and matter, "grasped" by mysterious Platonic (...) intuition. As conceived here, they are cognitive-event types in which agents predicate properties and relations of things--in using language, in perception, and in nonlinguistic thought. Because of this, one's acquaintance with, and knowledge of, propositions is acquaintance with, and knowledge of, events of one's cognitive life. This view also solves the problem of "the unity of the proposition" by explaining how propositions can be genuinely representational, and therefore bearers of truth. The problem, in the traditional conception, is that sentences, utterances, and mental states are representational because of the relations they bear to inherently representational Platonic complexes of universals and particulars. Since we have no way of understanding how such structures can be representational, independent of interpretations placed on them by agents, the problem is unsolvable when so conceived. However, when propositions are taken to be cognitive-event types, the order of explanation is reversed and a natural solution emerges. Propositions are representational because they are constitutively related to inherently representational cognitive acts. Strikingly original, What Is Meaning? is a major advance. (shrink)

_In the normal course of events, children manifest linguistic competence equivalent to that of adults in just a few years. Children can produce and understand novel sentences, they can judge that certain strings of words are true or false, and so on. Yet experience appears to dramatically underdetermine the com- petence children so rapidly achieve, even given optimistic assumptions about children’s nonlinguistic capacities to extract information and form generalizations on the basis of statistical regularities in the input. These considerations (...) underlie various (more specific) poverty of stimulus arguments for the innate specification of linguistic principles. But in our view, certain features of nativist arguments have not yet been fully appreciated. We focus here on three (related) kinds of poverty of stimulus argument, each of which has been supported by the findings of psycholinguistic investigations of child language. (shrink)

In this paper, I discuss some of Maximilian de Gaynesford’s arguments regarding indexicals. Although I agree with his treatment of the first singular personal pronoun as a prototype of demonstrative expressions, I challenge his refusal to treat indexicals as complex demonstratives. To offer an alternative to this refusal I try to develop a common ground from different theories that consider indexicals as linguistic constructions that embed a nonlinguistic element, following an original idea in Frege’s latest writings. These views form (...) the backdrop on which we can put forward the claim of treating all indexicals as complex demonstratives. In the central part of the paper, I criticize each of de Gaynesford’s arguments against the reduction of indexicals to complex demonstratives. Besides, I propose a new definition of the concept of “demonstration” as a nonlinguistic feature of all indexicals in their referential uses, to contrast de Gaynesford’s rejection of the idea that demonstrations are an essential feature of indexicals. Eventually, I strengthen my claim by distinguishing indexicals from proper names and definite descriptions on the ground that only perceptual indexicals necessarily require an accompanying demonstration. However, the main point of the paper is a negative one, that is the rejection of de Gaynesford’s arguments against the reduction of indexicals to complex demonstratives. More work is needed to reach a positive conclusion on this topic. (shrink)

A theory of nonlinguistic thought is incomplete without an account of nonlinguistic reasoning and the norms of rationality by which such reasoning is governed. This chapter tries to show how an account of nonlinguistic rationality emerges when we pose the question: What could count as evidence that a nonlinguistic creature is behaving rationally? There are several different forms of evidence that can come into play here. At the most sophisticated level, a creature is behaving rationally when (...) it is sensitive to the consequences of different courses of action, but there are types of rationality that do not involve such consequence-sensitivity. Different forms of rationality are appropriate to different types of explanation, and this chapter draws a distinction between level 1 rationality and level 2 rationality that maps onto the distinction between explanations of the type proposed by the minimalist and explanations that make use of belief-desire psychology.

Being and Time’s emphasis on practical activities has attracted much attention as an approach to meaning not modelled exclusively on language. However, understanding this emphasis is made more difficult by Heidegger’s notion of Rede, which he routinely characterizes as both language-like and basic to all disclosure. This paper assesses whether this notion can be both interpreted coherently and reconciled with Heidegger’s emphasis on intelligent nonlinguistic behaviours. It begins by identifying two functions of Articulacy – the demonstrative and articulatory – (...) and a potential source of incoherence in Heidegger’s analysis. Having reviewed some standard approaches to Heideggerian Articulacy, I show how Heidegger’s discussion of predicative judgements implies that language can be linked with different kinds of content. This allows Heidegger’s analysis to be read coherently, provided Articulacy is understood as having distinct purposive and predicative modes. The final section shows how this reading preserves a close connection between Articulacy and language while accommodating intelligent nonlinguistic behaviours. (shrink)

Is behavioral integration a necessary feature of belief in folk psychology? Our data from over 5,000 people across 26 samples, spanning 22 countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we argue that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely asserts that p, nonlinguistic behavioral evidence is disregarded. In light of this, (...) we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

We examine the influence of inferring interlocutors' referential intentions from their body movements at the early stage of lexical acquisition. By testing human participants and comparing their performances in different learning conditions, we find that those embodied intentions facilitate both word discovery and word‐meaning association. In light of empirical findings, the main part of this article presents a computational model that can identify the sound patterns of individual words from continuous speech, using nonlinguistic contextual information, and employ body movements (...) as deictic references to discover word‐meaning associations. To our knowledge, this work is the first model of word learning that not only learns lexical items from raw multisensory signals to closely resemble infant language development from natural environments, but also explores the computational role of social cognitive skills in lexical acquisition.

The proposal of a semantics for quotations using explanatory notions drawn from philosophical theories of pictures. In Quotations as Pictures, Josef Stern develops a semantics for quotations using explanatory notions drawn from philosophical theories of pictures. He offers the first sustained analysis of the practice of quotation proper, as opposed to mentioning. Unlike other accounts that treat quotation as mentioning, Quotations as Pictures argues that the two practices have independent histories, that they behave differently semantically, that the inverted commas employed (...) in both mentioning and quotation are homonymous, that so-called mixed quotation is nothing but subsentential quotation, and that the major problem of quotation is to explain its dual reference or meaning—its ordinary meaning and its metalinguistic reference to the quoted phrase attributed to the quoted subject. Stern argues that the key to understanding quotation is the idea that quotations are pictures or have a pictorial character. As a phenomenon where linguistic competence meets a nonlinguistic symbolic ability, the pictorial, quotation is a combination of features drawn from the two different symbol systems of language and pictures, which explains the exceptional and sometimes idiosyncratic data about quotation. In light of this analysis of verbal quotation, in the last chapters Stern analyzes scare quotation as a nonliteral expressive use of the inverted commas and explores the possibility of quotation in pictures themselves.

In a series of classic papers, Donald Davidson put forward an ingenious argument to challenge the ascription of minds to nonlinguistic animals. Davidson's conclusions have been mercilessly demolished in the literature by cognitive ethologists, but none of them have directly addressed Davidson's argument. First, this paper is an attempt to elucidate and evaluate Davidson's central argument for denying minds to nonlinguistic animals. Davidson's central argument puts forth a challenge to those of us who want to attribute minds to (...) nonlinguistic animals. Second, this paper uses counterexamples offered in the cognitive ethology literature to meet Davidson's challenge directly. (shrink)

_Rational Animals: The Teleological Roots of Intentionality_ offers an original account of the intentionality of human mental states, such as beliefs and desires. The account of intentionality in _Rational Animals_ is broadly biological in its basis, emphasizing the continuity between human intentionality and the levels of intentionality that should be attributed to animal actions and states. Establishing the goal-directed character of animal behavior, Mark Okrent argues that instrumentally rational action is a species of goal-directed behavior that is idiosyncratic to individual (...) agents and is distinguished by its novelty and flexibility. He also argues that some nonlinguistic animals are capable of instrumental rationality and that in the first instance, the contents of beliefs and desires are individuated by the explanatory role of those states in rationally accounting for such instrumentally rational behavior. The account of instrumental rationality offered in Rational Animals allows for understanding the practical rationality of linguistically competent human beings as a distinctive capacity of social animals capable of undertaking roles governed by socially sanctioned norms. Rational Animals will be of interest to cognitive scientists, philosophers of mind, philosophers of biology, philosophers of action, ethologists, and those interested in the debates concerning animal intelligence.

We argue that their characterization of the narrow language faculty is problematic for many reasons, including its dichotomization of cognitive capacities into those that are utterly unique and those (...) that are identical to nonlinguistic or nonhuman capacities, omitting capacities that may have been substantially modified during human evolution. We also question their dichotomy of the current utility versus original function of a trait, which omits traits that are adaptations for current use, and their dichotomy of humans and animals, which conflates similarity due to common function and similarity due to inheritance from a recent common ancestor. We show that recursion, though absent from other animals’ communications systems, is found in visual cognition, hence cannot be the sole evolutionary development that granted language to humans. Finally, we note that despite Fitch et al.’s denial, their view of language evolution is tied to Chomsky’s conception of language itself, which identifies combinatorial productivity with a core of “narrow syntax.” An alternative conception, in which combinatoriality is spread across words and constructions, has both empirical advantages and greater evolutionary plausibility. q 2005 Elsevier B.V.

Humans typically combine linguistic and nonlinguistic information to comprehend emotions. We adopted an emotion identification Stroop task to investigate how different channels interact in emotion communication. In experiment 1, synonyms of “happy” and “sad” were spoken with happy and sad prosody. Participants had more difficulty ignoring prosody than ignoring verbal content. In experiment 2, synonyms of “happy” and “sad” were spoken with happy and sad prosody, while happy or sad faces were displayed. Accuracy was lower when two channels expressed (...) an emotion that was incongruent with the channel participants had to focus on, compared with the cross-channel congruence condition. When participants were required to focus on verbal content, accuracy was significantly lower also when prosody was incongruent with verbal content and face. This suggests that prosody biases emotional verbal content processing, even when conflicting with verbal content and face simultaneously. Implications for multimodal communication and language evolution studies are discussed. (shrink)
