To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)

This paper focuses on the Korean suffix -te, which has been variously analyzed as a marker of tense, aspect, tense–aspect, mood, mood–tense, or evidentiality. I argue against all of these approaches and propose instead that -te is a spatial deictic past tense, which triggers an evidential environment. It refers to a certain past time when the speaker either observed an event or some evidence of the event within his (her) perceptual field. Thus, the denotation of -te is ‘overlap’, not between (...) the speaker's perceptual field and the event itself, but between the speaker's perceptual field and the evidence of the event at the past reference time. To account for this denotation, propose an ‘evidence trace’ function as well as a ‘speaker's perceptual trace’ function (cf. M. Faller, J Semantics 21:45–85, 2004). My analysis shows that suffixes like -ess (which is traditionally analyzed as a perfect) play two roles, as an indirect evidential and a perfect, depending on whether they appear with the spatial deictic tense -te or with a simple deictic tense. I argue that in Korean two distinct tense systems—the regular tense–aspect system and the spatial deictic tense–evidential system—exist in parallel. Thus the proposed analysis allows evidentials to be subsumed under the formal theory of tense, aspect, and mood. (shrink)

In this paper we address the issue of grounding for experiential concepts. Given that perceptual demonstratives are a basic form of such concepts, we examine ways of fixing the referents of such demonstratives. To avoid ‘encodingism’, that is, relating representations to representations, we postulate that the process of reference fixing must be bottom-up and nonconceptual, so that it can break the circle of conceptual content and touch the world. For that purpose, an appropriate causal relation between representations and the world (...) is needed. We claim that this relation is provided by spatial and object-centered attention that leads to the formation of object files through the function of deictic acts. This entire causal process takes place at a pre-conceptual level, meeting the requirement for a solution to the grounding problem. Finally we claim that our account captures fundamental insights in Putnam’s and Kripke’s work on “new” reference. (shrink)

This paper aims to analyze the deictic representations of person in the British and American media discourse, mostly focusing on such genres and subgenres as newspaper articles, interviews, letters to editors, opinions, headlines and advertisements. For this purpose, we wish to introduce a theoretical framework for the study and then we hope to present certain ways in which deictic expressions represent person. Theoretical framework for our study is based upon the socio-cognitive approach, which gives priority to individual practices and subjectivity (...) over social practices in discourse as well as the definition of discourse based on knowledge. The reason why we focus on the media discourse is obvious. The high degree of personalized conceptualization and contextualization dominated by a large number of subjective factors prevail in the above-mentioned genres and subgenres of media discourse. The deictic representations of person play the key role in this process. (shrink)

This essay introduces the concept of deictic abstraction , taking as a point of departure Husserl’s prototypical but insufficient description of the act of ideation in which a shade of color comes to givenness as an ideal object, i.e., a non-individual or abstract object, on the basis of a perceived individual object. This concept comprises not only color-ideation and ideations of universalities of the sensuous sphere , but all acts founded in perceptions in which ideal objects are directly referred to (...) by means of demonstrative expressions . This allows various types of deictic ideations or abstractions, corresponding to the degree of universality and the kind of ideal object concerned, to be brought to light through the analysis of particular cases of everyday acts of deictic abstraction, including deictic abstractions of predicative universals of the lowest level of universality ; deictic abstractions of non-predicative universals, especially of universal ways of doing something ; and deictic abstractions of individual styles of doing something . Deictic abstractions not only turn out to be constitutive for the formation of perceptual concepts of the lower and lowest levels, but also prove to be foundational for all kinds of learning in which schemata of actions are acquired from a model.

This paper proposes an approach to narrative deixis which offers a coherent analysis of the respective roles of proximal and distal deictic expressions. The paper starts by arguing that fictional narratives require an approach to deixis which modifies a number of broadly held assumptions, especially as regards the interaction between tense and other deictic forms. It then considers the widely discussed instance of the temporal adverb now in the context of Past Tense. The second part of the paper gives special (...) focus to demonstratives in narrative fiction, showing their role in temporal construals. It argues that both temporal and demonstrative expressions are primarily used to serve narrative viewpoint construction. Examples from several novels are then used to show how the proximal and distal choices of demonstratives, temporal adverbs and locative adverbs structure narrative viewpoint, including narrative representation of character experience. The paper concludes by proposing that in the context of fictional narratives the proximal/distal contrast is more relevant to meaning emergence than individual aspects of deixis, and that the construal of time can be achieved through the whole spectrum of deictic forms, not just tense and temporal adverbs such as now and then.

Ballard et al. claim that fixations bind variables to cognitive pointers. I comment on three aspects of this claim: (1) its contribution to the interpretation of indexical language; (2) empirical support for the use of very few deictic pointers; (3) nonetheless, abstract pointers cannot be taken as prototypical cognitive representations.

It is unlikely that Ballard et al.'s embodiment theory has general applicability to cognition because it is based on experiments that neglect the importance of meaning, purpose, and learning in cognitive tasks. Limitations of the theory are illustrated with examples from everyday life and the results of recent experiments using cognitive and visuomotor tasks.

Berber languages use the directionals =d and =nn to specify the deictic path of motion verbs. These clitics occur with a range of verbs from other semantic classes (e.g. change of state verbs, verbs of vision and perception), with which they can be attributed different meanings. The first goal of this paper is to provide a cross-dialectal description of these meanings. The second goal is to show the role of verbal semantics in their constructions and the overall distribution of the (...) clitics. Adopting Talmy’s framework (2000) of lexicalisation of semantic concepts, linked to the domain of space and motion, I propose that the particular meaning components lexicalised by the modified verb govern the occurrence of the clitics and their particular meaning.

Much attention has been paid to ‘deictic shifts’ in Ancient Greek literary texts. In this article I show that similar phenomena can be found in documentary texts. Contracts in particular display unexpected shifts from the first to the third person or vice versa. Rather than constituting a narrative technique, I argue that such shifts should be related to the existence of two major types of stylization, called the ‘objective’ and the ‘subjective’ style. In objectively styled contracts, subjective intrusions may occur (...) as a result of the scribe temporarily assuming himself to be the deictic center, whereas in subjectively styled contracts objective intrusions may occur as a result of the contracting parties dictating to the scribe, and the scribe not modifying the personal references. There are also a couple of texts which display more extensive deictic alter­nations, which suggests that generic confusion between the two major types of stylization may have played a role. (shrink)

The paper focuses on a specific type of referring legal provisions, in which the referring phrase contains a component that indicates the position of a certain fragment of the same text of a normative act by determining the position of that fragment in relation to the fragment in which the given referring phrase is located. Despite the fact that these referrals, called deictic, may be perceived as uncomplicated in structure and as functioning correctly in legal texts, many theoretical as well (...) as practical problems arise during their drafting and legal interpretation. The article attempts to reveal, organize and name these problems basing on the conceptual grid formulated by Studnicki, Łachwa, Fall and Stabrawa as a universal, although not widely known outside Polish jurisprudence, tool for analysing and solving referring provisions as elements of various legal systems, especially continental ones. Texts of selected Polish Codes have been chosen as an illustrative material of deictic referrals which have been incorrectly formulated as leaving space for interpretative doubts in terms of place of indication and place of reference, which also causes a potential problem of the deferred ostension phenomenon noticed by Quine. The author argues that proper drafting of referring legal provisions with deictic indication requires that the legislator should have extensive pragmalinguistic knowledge and is an essential part of law-making oriented towards achieving comprehensibility of texts of normative acts, especially as important as Codes.

In English, deictic verbs of motion, such ascomecan encode the perspective of the speaker, or another individual, such as the addressee or a narrative protagonist, at a salient reference time and location, in the form of an indexical presupposition. By contrast, Spanish has been claimed to have stricter requirements on licensing conditions forvenir(“to come”), only allowing speaker perspective. An open question is how a bilingual learner acquiring both English and Spanish reconciles these diverging language-specific restrictions. We face this question head (...) on by investigating narrative productions of young Spanish-English bilingual heritage speakers of Spanish, in comparison to English monolingual and Spanish dominant adults and children. We find that the young heritage speakers producevenirin linguistic contexts where most Spanish adult speakersdo not, but where English monolingual speakersdo, and also resemble those of young monolingual Spanish speakers of at least one other Spanish dialect, leading us to generate two mutually-exclusive hypotheses: (a) the encoding of speaker perspective in the young heritage children is cross-linguistically influenced by the more flexible and dominant language (English), resulting in a wider range of productions by these malleable young speakers than the Spanish grammar actually allows, or (b) the young Spanish speakers are exhibiting productions that are in fact licensed in the grammar, but which are pruned away in the adult productions, being supplanted by other forms as the lexicon is enriched. Given independent evidence of the heritage speakers' robust Spanish linguistic competence, we turn to systematically-collected acceptability judgments of three dialectal varieties of monolingual adult Spanish speakers of the distribution of perspective-taking verbs, to assess their competence and adjudicate between (a) and (b). We find that adultsaccept venirin contexts in which they do notproduceit, leading us to argue that (a)venirisnotobligatorily speaker-oriented in Spanish, as has been claimed, (b) adults may not producevenirin these contexts because they instead select more specific motion verbs, and (c) for heritage bilingual children, the more dominant language (English) may support the grammatically licensed but lexically-constrained productions in Spanish.

Defense of a non-psychological dynamics of demonstrative thoughts.

The motor system might well use deictic strategies when subjects learn a new task. However, its not clear that Ballard et al. show this. Multiple eye-fixations may have little to do with deixis and more to do with the unfamiliarity of the task. In any case, deixis does not entail embodiment, since a disembodied Cartesian brain could use deictic strategies.

Languages around the world differ in terms of the number of adnominal and pronominal demonstratives they require, as well as the factors that impact on their felicitous use. Given this cross-linguistic variation in deictic demonstrative terms, and the features that determine their felicitous use, an open question is how this is accommodated within bilingual cognition and language. In particular, we were interested in the extent to which bilingual language exposure and practice might alter the way in which a bilingual is (...) using deictic demonstratives in their first language. Recent research on language attrition suggests that L2 learning selectively affects aspects of the native language, with some domains of language competence being more vulnerable than others. If demonstratives are basic, and acquired relatively early, they should be less susceptible to change and attrition. This was the hypothesis we went on to test in the current study. We tested two groups of native Spanish speakers, a control group living in Spain and an experimental group living in Norway using the Memory game paradigm. Contra to our expectations, the results indicate a significant difference between the two groups in use of deictic terms, indicative of a change in the preferred number of terms used. This suggests that deictic referential systems may change over time under pressure from bilingual language exposure. (shrink)

The aim of this study is to analyze the relationship between rhythmic movements and deictic gestures at the end of the first year of life, and to focus on their unimodal or multimodal character. We hypothesize that multimodal rhythmic movement performed with an object in the hand can facilitate the transition to the first deictic gestures. Twenty-three children were observed at 9 and 12 months of age in a naturalistic play situation with their mother or father. Results showed that rhythmic (...) movements with objects in the hand are a frequent behavior in children's repertoires. Rhythmic behaviors tend to decrease from 9 to 12 months, specifically when they are unimodal. Multimodal rhythmic behavior production at 9 months is positively related with proximal deictic gestures 3 months later. Multimodal rhythmic movements are not directly related to distal deictic gestures, but are indirectly related via proximal deictic gestures. These results highlight the relevance of multimodal behaviors in the transition to the use of early gestures, and can be considered as a transitional phenomenon between the instrumental action and early communicative gestures.

English deictic and existential there-constructions have been analyzed as constituting a single radial category of form—meaning pairings, related through motivated links, such as metaphor (Lakoff 1987). By comparison, existentials and deictic demonstratives in French make use of two distinct radial categories. The current study analyzes the varied senses of French deictic demonstratives (voilà ‘there is’ and voici ‘here is’) and the existential (il y a ‘there is’). We argue that the syntactic behavior of each of their senses is best explained (...) by the semantic and pragmatic function of that sense, in combination with constraints imposed by its relation to other senses. A cross-linguistic comparison of the deictic demonstrative and existential constructions in French and English supports this claim: despite the different historical origins of these forms in the two languages, they display a strikingly similar array of uses and formal constraints. The parallel evolution of deictics and existentials in these two languages is interpreted as a case of convergent evolution of linguistic items, much like convergent evolution in biological species.

In contrast to Constructivist Views, which construe perceptual cognition as an essentially reconstructive process, this article recommends the Deictic View, which grounds perception in perceptual-demonstrative reference and the use of deictic tracking strategies for acquiring and updating knowledge about individuals. The view raises the problem of how sensory-motor tracking connects to epistemic and integrated forms of tracking. To study the strategies used to solve this problem, we report a study of the ability to track distal individuals when only their directions (...) can be perceived and not their locations. We introduce a new experimental paradigm named the 'Modified Traveling Salesman Problem' (MTSP), which requires subjects to visit n invisible targets in a 2D display once each. Surprisingly, subjects are competent at this task for up to 10 targets. We consider two types of tracking strategies that subjects might use: 'location-based' strategies and 'deictic direction-based' strategies. A number of observations suggest that subjects used the latter, at least for larger numbers of targets. We hypothesize that subjects used perceptual-demonstrative reference and deictic strategies (i) to perform the sensory-motor tracking of directional segments, (ii) to bind the segments with their updated status in the task, and (iii) to perform the epistemic tracking of invisible targets by means of perception-based inferences.

Determining what content is expressed by a demonstrative when its reference cannot be determined is a problem for those who assume that demonstrative reference is cognized by interpreters and demonstrative meaning has a mere indicative role. Here, I explore a concept of content that gives meaning a cognitively relevant role, namely, John Perry’s classificatory concept of content. With that purpose, I compare the interpretation of a deictic demonstrative in two cases: for an eavesdropper and a conversational participant, aiming to show (...) that meaning, in the form of reflexive rules, can be recruited to play the role of content when information is scarce.

Eye movements play a variety of roles in perception, cognition, and communication. The roles are revealed by the duration of fixations reflecting the quality of processing in the first line. We describe possible roles of eye fixations in different temporal diapasons. These forms of processing may be specific to sensorimotor coordinations. Any generalization to other domains should be cautious.

Last year at VSS, Bullot, Droulez & Pylyshyn reported studies using a Modified Traveling Salesman Paradigm in which a virtual vehicle had to visit up to 10 targets once and only once, and in which the invisible targets were identified only by line segments pointing from the vehicle toward each target. We hypothesized that subjects used two distinct strategies: A “location-based strategy”, which kept track of where targets were located in screen coordinates, and a “segment-based strategy” that kept track of (...) which segments corresponded to visited targets. We report new studies that further explore these two strategies. Subjects passively observed a computer-controlled virtual vehicle that visited a number of targets. Two forms of display were used: an “Allocentric” display, in which the vehicle moved and the targets remained fixed in screen coordinates, and an “Egocentric” display, in which the vehicle's position on the screen remained fixed while the targets moved -- as if the environment were being viewed by an observer on the vehicle. At the end of each trial, the directional segments were extended to the edge of the screen and subjects were asked to perform two tasks by referring to these segments. In the “status task” observers had to indicate for each segment whether the corresponding target had been visited or not. In the “locating task” they had to locate each target along its directional segment. Performance on these two tasks measures the use of the two hypothesized strategies. Results showed that observers do well on the status task with 4 or 6 targets in both display conditions, but do poorly on the locating task, especially in the egocentric condition when there are more targets. These results are consistent with the hypothesis that in the egocentric condition the MTSP task is carried out primarily by segment-tracking, which can be viewed as a deictic strategy. (shrink)

Kierkegaards deiktische Theologie wird in einer Reihe von Textinterpretationen entwickelt, die seine oft übersehenen erbaulichen Reden in einem neuen Licht präsentieren. Das Buch setzt sich mit dem traditionellen Bild der Religiosität bei Kierkegaard auseinander, wie sie in den Begriffen der Religiosität A und B zum Ausdruck kommt, und bringt neue Argumente im Sinne einer deiktischen Theologie. Sie wird in einer doppelten Perspektive entfaltet: Der Mensch richtet seinen Blick auf Gott - und Gott begegnet ihm, indem er den Menschen auf seinen (...) Nächsten hinweist. Deiktische Theologie ist weder eine Schöpfungstheologie (Religiosität A) noch eine Offenbarungstheologie (Religiosität B), sondern sie erfasst die Spannung zwischen Schöpfung und Offenbarung, die u.a. im trinitarischen Gottesbegriff begründet wird. Die Entwicklung der deiktischen Theologie Kierkegaards geschieht in der Interpretation zentraler Texte aus den erbaulichen Reden, der Einübung im Christentum sowie der Unwissenschaftlichen Nachschrift. Wichtige Themen sind darüber hinaus: die Zeitlichkeit, das Verhältnis zwischen dem Humanen und dem Christlichen, die Reue, die Sünde, das Abendmahl, das Leiden, die Nachfolge Christi, Himmelfahrt und Auferstehung.

This study investigates a new experimental paradigm called the Modified Traveling Salesman Problem. This task requires subjects to visit once and only once n invisible targets in a 2D display, using a virtual vehicle controlled by the subject. Subjects can only see the directions of the targets from the current location of the vehicle, displayed by a set of oriented segments that can be viewed inside a circular window surrounding the vehicle. Two conditions were compared. In the “allocentric” condition, subjects (...) see the vehicle move across the screen and change orientation under their command. The “egocentric” condition is similar except for how the information is provided: the position and orientation of the vehicle icon remains fixed at the center of the screen and only target directions, as indicated by the oriented segments, change as the subject “moves” the vehicle. The unexpected finding was that this task can be performed, in either condition, for up to 10 targets. We consider two possible strategies that might be used, a location-based strategy and a segment strategy. The location-based strategy relies on spatial memory and attempts to infer the locations of all the targets. The segment strategy is more local and focuses on the directional segments themselves, keeping track of the ones that represent already-visited targets. A number of observations suggest that the segment strategy was used, at least for larger numbers of targets. According to our hypothesis, keeping track of the segments requires one to use indexical reference for associating the segments with their status in the task - given by current status predicates Visited or Not-visited -, perhaps using visual indexes, deictic pointers, or object files.

For all his profound interest in Secondness and its manifestation in various kinds of indices, including deictics, Peirce rarely addresses the inter-pronominalrelationships. Whilst the American founder of semiotics would designate language as a whole to Thirdness, only within the larger framework of which deictics can work, the German philosopher Cassirer observes that “what characterizes the very first spatial terms that we find in language is their embracing of a defi nite ‘deictic’ function”. For Cassirer the significance of pronominals, (...) especially the I-Thou relationship, lies in its impact on the development of spatial concept that lays the foundation of symbolic forms. It may look strange why the “designatives” of I, Thou, He, in Peirce’s own terms, so obvious in their categorial and empirical differentiation, should fail to be reduceable to the triad of Firstness, Secondness, and Thirdness. It is interesting, however, that in his 1906 correspondence with Lady Welby, Peirce should refer to the strange “Communicational Interpretant”, or “the Cominterpretant, which is a determination of that mind into which the minds of utterer and interpreter have to be fused in order that any communication should take place”. Peirce asserts that this communication of a Form, say, being in love, is made possible by sign. This paper discusses Peirce’s and Cassirer’s references to deictics or indexical sign, in particular, inter-personal relationships, in light of Benveniste’s concept of discourse, and probes into a possible subtext underlying the Peirce-Welby correspondence.

Ballard et al. model eye position as a deictic pointer for spatial perception. Evidence from research on gaze control indicates, however, that shifts in actual eye position are neither necessary nor sufficient to produce shifts in spatial perception. Deictic context is instead provided by the interaction between two deictic pointers; one representing actual eye position, and the other, intended eye position.

The present study examines whether deictic time and valence are mentally associated, with a link between future and positive valence and a link between past and negative valence. We employed a novel paradigm, the two-choice-sentence-completion paradigm, to address this issue. Participants were presented with an initial sentence fragment that referred to an event that was either located in time or of different valence. Participants chose between two completion phrases. When the given dimension in the initial fragment was time, the two (...) completion phrase alternatives differed in valence. However, when the given dimension in the initial fragment was valence, the two completion phrase alternatives differed in time. As expected, participants chose completion phrases consistent with the proposed association between time and valence. Additional analyses involving individual differences concerning optimism/pessimism revealed that this association is particularly pronounced for people with an optimistic attitude. (shrink)

The central claim of this book is that I is a deictic term, like the other singular personal pronouns You and He/She. This is true of the logical character, inferential role, referential function, expressive use, and communicative role of all and only expressions used to formulate first-personal reference in any language. The first part of the book shows why the standard account of I as a ‘pure indexical’ (‘purism’) should be rejected. Purism requires three mutually supportive doctrines which turn out (...) to be myths: a) that a simple rule is sufficient to give the meaning of I (‘rule theory’); b) that one can use I to express thoughts without having to identify what is being referred to (‘independence’); and c) that as a matter of the meaning of I, any use of the term is logically guaranteed against failure to refer (‘the guarantee’). The second part of the book shows why the radically new account of I should be endorsed as a deictic term. Substitution instances and the behaviour of I in inference reveal that it has an obligatorily deictic logical character and inferential role. I fulfils its referential function in the deictic way, providing determinacy of reference by making an individual referentially salient in the extra-sentential context. The discriminability of the referent of an I-use depends on recognizing the referentially salient individual. This is true of its discriminability both to the reference-maker and to the audience. So I has the expressive use and communicative role of a deictic term. The conclusion of the book directs research towards the next step, showing how the meaning of I may be used to elucidate the thoughts expressed by the term, and from there questions relating to self-knowledge, practical reasoning, belief-acquisition, and belief-ascription.

This article is concerned with social and interactional processes that simplify pragmatic acts of intention attribution. The empirical focus is a series of interactions among DeafBlind people in Seattle, Washington, where pointing signs are used to individuate objects of reference in the im-mediate environment. Most members of this community are born deaf and slowly become blind. They come to Seattle using Visual American Sign Language, which has emerged and developed in a field organized around visual modes of access. However, as (...) vision deteriorates, links be-tween deictic signs and the present, remembered, or imagined environment erode in idiosyncratic ways across the community of language-users, and it becomes increasingly difficult for partici-pants to converge on objects of reference. In the past, DeafBlind people have addressed this problem by relying on sighted interpreters. Under the influence of the recent “pro-tactile” movement, they have turned instead to one another to find new solutions to their referential prob-lems. Drawing on analyses of 120 hours of videorecorded interaction and language-use, detailed fieldnotes collected during twelve months of sustained anthropological fieldwork, and more than 15 years of involvement in this community in a range of capacities, I show how DeafBlind peo-ple are generating new and reciprocal modes of access to their environment, and how this pro-cess is aligning language with context in novel ways. I propose two mechanisms that can account for this process: deictic integration and embedding in the social field. I argue that together, these interactional and social mechanisms yield a deictic system set to retrieve a restricted range of values from the extra-linguistic context, thereby attenuating the cognitive demands of intention-attribution and narrowing the gap between DeafBlind minds.

Neural correlates exist for a basic component of logical formulae, PREDICATE(x). Vision and audition research in primates and humans shows two independent neural pathways; one locates objects in body-centered space, the other attributes properties, such as colour, to objects. In vision these are the dorsal and ventral pathways. In audition, similarly separable “where” and “what” pathways exist. PREDICATE(x) is a schematic representation of the brain's integration of the two processes of delivery by the senses of the location of an arbitrary (...) referent object, mapped in parietal cortex, and analysis of the properties of the referent by perceptual subsystems. The brain computes actions using a few “deictic” variables pointing to objects. Parallels exist between such nonlinguistic variables and linguistic deictic devices. Indexicality and reference have linguistic and nonlinguistic (e.g., visual) versions, sharing the concept of attention. The individual variables of logical formulae are interpreted as corresponding to these mental variables. In computing action, the deictic variables are linked with “semantic” information about the objects, corresponding to logical predicates. Mental scene descriptions are necessary for practical tasks of primates, and preexist language phylogenetically. The type of scene descriptions used by nonhuman primates would be reused for more complex cognitive, ultimately linguistic, purposes. The provision by the brain's sensory/perceptual systems of about four variables for temporary assignment to objects, and the separate processes of perceptual categorization of the objects so identified, constitute a pre-adaptive platform on which an early system for the linguistic description of scenes developed. Key Words: argument; attention; deictic; dorsal; logic; neural; object; predicate; reference; ventral. (shrink)

This commentary raises three questions about the target article: What are pointers or deictic devices? Why insist on deictic codes for cognition rather than deixis simpliciter? And in what sense is cognition embodied, on this view?

Deictic (or pointing) gestures are traditionally known to have a simple function: to supply something as the referent of a demonstrative linguistic expression. I argue that deixis can have a more complex function. A deictic gesture can be used to _say something_ in conversation and can thereby become a full discourse move in its own right. To capture this phenomenon, which I call _rich demonstration_, I present an update semantics on which deictic gestures can indicate situations from a conversation’s context (...) and those situations coherently connect to prior discourse to generate information.
