Résumé :
AbstractThe current study uses principles from Cognitive Grammar to better account for the symbolic integration of gesture and speech. Drawing on data collected from language use, we examine the use of two attention-directing strategies that are expressed through gesture, beats and pointing. It has been claimed that beats convey no semantic information. We propose that beat gestures are symbolic structures. It has also been noted that beats are often overlaid on other gestures. To date, however, no detailed explanation has been offered to account for the conceptual and phonological integration of beats with other co-expressed gestures. In this paper, we explore the integration of beats and pointing gestures as complex gestural expressions. We find that simple beat gestures, as well as beat gestures co-expressed with pointing gestures, are used to direct attention to meanings in speech that are associated with salient components of stancetaking acts. Our account further reveals a symbolic motivation for the apparent “superimposing” of beats onto pointing gestures. By closely examining actual usage events, we take an initial step toward demonstrating how the symbolic elements of both beats and points are integrated in multimodal constructions.

Résumé :
Co-speech gestures in autism spectrum disorder (ASD) are poorly understood. Historically, all gestures were thought to be reduced in this social-communicative disorder; however, reduced gestures have not been consistently demonstrated in the empirical literature. Just as protodeclarative pointing is reduced in young children with ASD, while protoimperative pointing is not, the varied functions of co-speech gesture may explain these mixed findings. Verbally fluent adolescents with ASD (n = 18) and controls (n = 18) completed a narrative task and a standardized executive function task. Gestures on the narrative task, which serve a wide range of social and cognitive functions, were reduced in ASD. Gestures on the executive function task, which serve primarily cognitive functions, were increased in ASD. Gesture function may be the best predictor of the presence or absence of gesture in ASD. Despite reduced social-communicative gestures, individuals with ASD may benefit from gesture’s internal, cognitive functions.

Résumé :
This paper examines the nature and properties of gestural and vocal deixis in verbal languages (VL) and signed languages (SL). We focus on two classes of pointing gestures which we argue need to be distinguished: (1) prototypical ostensive printings directing an interlocutor’s visual attention towards extralinguistic objects; (2) pointings to self and to one’s own addressee expressing person reference distinctions similar to those expressed by spoken pronouns. Drawing on previous work on SL and VL, and on new evidence on the development of deictic gestures and words for demonstrative vs. person reference in hearing children, we show how the two classes of pointings we explore convey indexical relationships of different complexity, and thus need to be distinguished in order to achieve a more appropriate understanding of gestural deixis, and of its relationship with vocal and, more generally, linguistic deixis.

Résumé :
In everyday human communication, we often express our communicative intentions by manually pointing out referents in the material world around us to an addressee, often in tight synchronization with referential speech. This study investigated whether and how the kinematic form of index finger pointing gestures is shaped by the gesturer's communicative intentions and how this is modulated by the presence of concurrently produced speech. Furthermore, we explored the neural mechanisms underpinning the planning of communicative pointing gestures and speech. Two experiments were carried out in which participants pointed at referents for an addressee while the informativeness of their gestures and speech was varied. Kinematic and electrophysiological data were recorded online. It was found that participants prolonged the duration of the stroke and poststroke hold phase of their gesture to be more communicative, in particular when the gesture was carrying the main informational burden in their multimodal utterance. Frontal and P300 effects in the ERPs suggested the importance of intentional and modality-independent attentional mechanisms during the planning phase of informative pointing gestures. These findings contribute to a better understanding of the complex interplay between action, attention, intention, and language in the production of pointing gestures, a communicative act core to human interaction.

Résumé :
By assessing the precision of gestural interactions with touchscreen targets, the authors investigate how the type of gesture, target location, and scene visibility impact movement endpoints. Participants made visually and memory-guided pointing and swiping gestures with a stylus to targets located in a semicircle. Specific differences in aiming errors were identified between swiping and pointing. In particular, participants overshot the target more when swiping than when pointing and swiping endpoints showed a stronger bias toward the oblique than pointing gestures. As expected, the authors also found specific differences between conditions with and without delays. Overall, the authors observed an influence on movement execution from each of the three parameters studied and uncovered that the information used to guide movement appears to be gesture specific.

Résumé :
This study investigated the production of spontaneous pointing gestures in 26 toddlers, who were observed during free play time at day nursery. Pointing gestures and their different features (e.g., handedness, vocalizations, form and function of gesture) were recorded for a total observation time of 100 hours. Results revealed that the vast majority of pointing gestures were right-handed and accompanied by vocalizations, emphasizing the tight interconnection between speech and gesture from an early stage of development. Whole-hand gestures were more frequently used in imperative contexts, whereas index extensions were more frequently produced in declarative ones. Moreover, the use of declarative gestures and index extensions were found to increase with age. Implications concerning the origins of imperative and declarative pointing are discussed.

Résumé :
In contrast to apes’ seemingly sophisticated skill at producing pointing gestures referentially, the comprehension of other individual’s pointing gestures as a source of indexical information seems to be less pronounced.One reason for apes’ difficulty at comprehending pointing gestures might be that in former studies they were mainly confronted with human declarative pointing gestures, whereas apes have largely been shown to point imperatively and towards humans. In the present study bonobos, chimpanzees and orangutans were confronted with a conspecific’s imperative pointing gesture in a competitive context, therefore mirroring former studies that have investigated apes’ skills at producing these gestures.However, apes in the present study did not use their conspecific’s pointing gestures. Apes have been shown to use indexical information when provided noncommunicatively and to interpret other individuals’ actions in terms of motives. Thus, it is discussed whether apes treat a pointing gesture as intentional act of indexical reference.

This paper provides an overview of recent studies that have investigated the development of pointing behaviors in infants and toddlers. First, we focus on deictic gestures and their role in language development, taking into account the different hand shapes and the different functions of pointing, and examining the cognitive abilities that may or may not be associated with the production of pointing gestures. Second, we try to demonstrate that when a distinction is made between pointing gestures and manipulative activities, the study of children’s hand preference can help to highlight the development of speech-gesture links.

The strongest chapters have fascinating insights from psychology, neuropsychology, and Deaf studies on the interconnections between language and gesture. Paul Ekman catalogs different kinds of gestures found accompanying speech, including “emblems,” or socially learned gestures with consistent meaning like “the finger”; “illustrators,” like deictic pointing gestures; “manipulators,” which include scratching and fiddling with hair; “regulators,” the gestural equivalents of the “uh-huhs” and “mmms” of the attentive listener; and “emotional expressions” such as smiles and tears.

Résumé :
Abstract The first gesture produced by children before they utter their first word has the form of an extended index finger. T his gesture is often described as a prototypical pointing gesture and is regarded as a universal display of intentional communication in most explored cultures (Volterra et al. 2011; Tomasello 2007). It is interesting, however, that in many cultures, a pointing gesture realized with index finger extended is regarded as rude, especially when made by adults or by children past the age of learning to speak. T he aim of this paper is to answer some questions concerning the form and usage of pointing gestures performed by native speakers of Polish. T his paper is focused on potential determinants of the form of pointing gestures, on the Polish cultural norms for indicating people and objects, as well as on the perception of pointing gestures. T he study is based on two experiments and a survey.

Texte intégral
Résumé :
Previous natural observations have found a robust correlation between infants’ spontaneous gesture production and vocabulary development: the onset and frequency of infants’ pointing gestures are significantly correlated to their subsequent vocabulary size (Colonnesi, Stams, Koster, & Noom, 2010). The present study first examined the correlations between pointing and vocabulary size in an experimental setting, and then experimentally manipulated responses to pointing, to investigate the role of pointing in infants’ forming word-object associations. In the first experiment, we elicited 12- to 24-month old infants’ pointing gestures to 8 familiar and 8 novel objects. Their vocabulary was assessed by the MacArthur Communicative Development Inventory (MCDI): Words and Gestures. Results showed that 12-16 month old infants’ receptive vocabulary was positively correlated to infants’ spontaneous pointing. This correlation, however, was not significant in 19-24 month old infants. This experiment thus generalizes the previous naturalistic observation findings to an experimental setting, and shows a developmental change in the relation between pointing and receptive vocabulary. Together with prior studies, it suggests a possible positive social feedback loop of pointing and language skills in infants younger than 18 months old: the bigger vocabulary size infants have, the more likely they point, the more words they hear, and then the faster they develop their vocabulary. In the second experiment, we tested whether 16-month-old infants’ pointing gestures facilitate infants’ word learning in the moment. Infants were randomly assigned to one of three conditions: the experimenter labeled an unfamiliar object with a novel name 1) immediately after the infant pointed to it (the point contingent condition); 2) when the infant looked at it; or 3) at a schedule predetermined by a vocabulary-matched infant in the point contingent condition. After hearing the objects’ names, infants were presented with a word learning test. Results showed that infants successfully selected the correct referent above chance level only in the point contingent condition, and their performance was significantly better in the point contingent condition than the other two conditions. Therefore, only words that were provided contingently after pointing were learned. Taken together, these two studies further our understanding of the correlation between early gesture and vocabulary development and suggest that pointing plays a role in early word learning.

Texte intégral
Résumé :
This thesis studies the different ways the driver uses pointing gestures as resources of embodied references, requests and directives, as well as how these gestures are modified to ensure the successful transfer of meaning to the recipient even when facing the challenges of mobility and multitasking which are essentially inherent in the conversational setting of the car. Specific focus is on the pointing gesture’s witnessability, duration, domain of scrutiny, and the apex location in relation to the verbal resources used. As a source of data, this thesis employs three corpora of naturally occurring, conversation. The Habitable Cars corpus features mostly native English speakers, the Talk&Drive corpus features speaker from several different nationalities and languages, and the Kokkola corpus features only native Finnish speakers. Keeping in with the research methods of conversation analysis, transcripts of the conversation situations are provided and serve as a source of analysis. The main finding of this research is that in order to distinguish pointing gestures used for referring, requesting and directing from each other, the driver modifies the gesture’s witnessability. Pointing gestures used for referring tend to be the shortest in duration and the least witnessable from the recipient’s point of view. Pointing gestures used for directing tend to the longest in duration and the most witnessable, with the requesting gestures falling somewhere between these two extremes. Factors such as urgency and the increased need to multitask between talking and driving also have an effect on the gesture’s delivery, increasing or decreasing the overall witnessability of the gesture depending on the situation, and sometimes blurring the line between the three social actions examined in this thesis. However, the embodied resources used for performing the three social actions are distinguishable from each other and the initial categorization is justifiable. This thesis continues the research into gesture witnessability, and it’s importance in prioritization and acquisition of the referent. However, this thesis moves the concept of witnessability away from the world of ‘professional vision’, and further develops it by examining its interplay with the verbal resources, gesture duration and domain of scrutiny
Tutkimus käsittelee auton kuljettajan osoittavia eleitä kehollisina resursseina kolmen sosiaalisen toiminnon, viittaamisen, pyytämisen, ja käskemisen, toteuttamisessa. Tutkimuksessa tarkastellaan myös, miten eleitä muokataan, jotta ne välittäisivät toiminnon viestin vastaanottajalle myös silloin kun ympäristön haasteellisuus lisääntyy. Haasteellisuutta voivat lisätä muun muassa mobiliteetti tai lisääntynyt tarve tuottaa useita rinnakkaisia toimintajaksoja. Tutkimus keskittyy erityisesti eleen havaittavuuteen ja kestoon, eleen luomaan tarkkailun alueeseen (domain of scrutiny) sekä sen huipentuman sijaintiin suhteessa verbaalisiin resursseihin. Tutkimusaineistona on käytetty kolmea korpusta, jotka sisältävät luontaista keskustelua. Habitable Cars -korpus sisältää enimmäkseen äidinkieleltään englanninkielisiä puhujia, Talk&Drive-korpus useamman eri kielen edustajia, ja Kokkola-korpus yksinomaan suomenkielisiä puhujia. Keskusteluanalyyttisen tutkimuksen periaatteita noudattaen keskustelutilanteista on tuotettu transkriptiota, jotka toimivat analyysin lähteenä. Tärkeimpänä löydöksenä voitaneen pitää sitä, että kuljettaja muokkaa ensisijaisesti eleen havaittavuutta erottaakseen keholliset viittaukset, pyynnöt ja käskyt toisistaan. Kehollisten viittausten osoittava ele on kestoltaan lyhyin ja havaittavuudeltaan pienin, kun taas käskyyn käytetty ele on kestoltaan pisin sekä havaittavuudeltaan suurin. Pyyntöihin käytetyt eleet ovat kestoltaan ja havaittavuudeltaan näiden kahden välimaastossa. Tilanteen kiireellisyys sekä rinnakkaiset toimintajaksot voivat vaikuttaa eleen havaittavuuteen joko lisäten tai vähentäen sitä sekä usein hämärtäen rajoja kolmen tarkastellun sosiaalisen toiminnon välillä. Tästä huolimatta tarkasteltujen kolmen toimintokategorian eleet ovat erotettavissa toisistaan. Täten alkuperäinen kategorisointi on oikeutettu. Tämä tutkimus on jatkoa aiemmille tutkimuksille eleen havaittavuudesta sekä sen vaikutuksesta kohteen löytämiseen ja priorisointiin. Tutkimuksessa havaittavuuden käsite kuitenkin siirretään niinkutsutun ammattinäön piiristä lähemmäs arkipäivää. Lisäksi havaittavuuden käsitettä syvennetään tutkimalla sen suhdetta ja vuorovaikutusta verbaalisiin resursseihin, eleen kestoon sekä tarkkailun alueeseen

Résumé :
Bien que l’utilisation précoce de gestes communicatifs par de jeunes enfants soit reconnue comme étant étroitement liée au développement du langage (e.g., Colonnesi et al., 2010), la nature des liens gestes–langage doit encore être clarifiée. Cette thèse a pour but d’étudier la production de gestes de pointage au cours du développement afin de déterminer si la relation prédictive et facilitatrice entre les gestes et l’acquisition du langage implique des fonctions spécifiques du pointage, en association avec des caractéristiques spécifiques en terme de forme de mains, regard et vocalisations. De plus, une attention particulière a été apportée à l’étude des préférences manuelles dans le but de mieux comprendre le développement de la spécialisation hémisphérique gauche pour les comportements communicatifs. Nos résultats ont révélé des relations complexes entre le langage, les gestes communicatifs et les activités de manipulation, qui dépendent de la fonction des gestes (i.e., pointage impératif versus déclaratif) et des étapes spécifiques de l’acquisition du langage. Les gestes déclaratifs sont plus étroitement associés au développement de la parole que les gestes impératifs, au-moins avant la période d’explosion lexicale. De plus, la comparaison des patterns de préférence manuelle chez l’enfant et l’adulte a montré une plus grande proximité pour les gestes que pour la manipulation d’objet. L’asymétrie manuelle droite pour les gestes communicatifs est ainsi établie à des stades précoces, ce qui suggère un rôle primordial des gestes dans la spécialisation hémisphérique.Finalement, nos résultats ont mis en évidence l’existence d’un système de communication dans l’hémisphère cérébral gauche contrôlant à la fois la communication gestuelle et verbale, qui pourrait avoir une origine phylogénétique ancienne (e.g., Corballis, 2010). Par conséquent, le présent travail peut améliorer notre compréhension des origines du langage, y compris des mécanismes de la spécialisation cérébrale pour les comportements communicatifs
Even though children’s early use of communicative gestures is recognized as being closely related to language development (e.g., Colonnesi et al., 2010), the nature of speech–gestures links still needs to be clarified. This dissertation aims to investigate the production of pointing gestures during development to determine whether the predictive and facilitative relationship between gestures and language acquisition involves specific functions of pointing, in association with specific features in terms of hand shape, gaze and accompanying vocalizations. Moreover, special attention was paid to the study of hand preferences in order to better understand the development of left hemisphere specialization for communicative behaviors. Our results revealed complex relationships between language, communicative gestures and manipulative activities depending on the function of gestures (i.e., imperative versus declarative pointing) as well as on specific stages of language acquisition. Declarative gestures were found to be more closely associated with speech development than imperative gestures, at least before the lexical spurt period. In addition, the comparison of hand-preference patterns in adults and infants showed stronger similarity for gestures than for object manipulation. The right-sided asymmetry for communicative gestures is thus established in early stages, which suggests a primary role of gestures in hemispheric specialization.Finally, our findings have highlighted the existence of a left-lateralized communication system controlling both gestural and vocal communication, which has been suggested to have a deep phylogenetic origin (e.g., Corballis, 2010). Therefore, the present work may improve current understanding of the evolutionary roots of language, including the mechanisms of cerebral specialization for communicative behaviors

Texte intégral
Résumé :
Le travail présenté dans cette thèse vise à étudier la coordination entre gestes manuels et parole lors de la production d'énoncés multimodaux. Les études menées s'intéressent plus particulièrement aux relations temporelles entre les deux modalités. Cette coordination a été étudiée plus précisément dans le cadre de la désignation qui est réalisable à la fois dans la modalité manuelle (geste de pointage) et dans la modalité parole (" montrer avec la voix ", en utilisant la focalisation et/ou les démonstratifs par exemple). Les études présentées ont été menées dans un environnement contrôlé de laboratoire afin d'obtenir des mesures précises et reproductibles en minimisant les facteurs extérieurs de variations intra- et inter-participants. Les productions des locuteurs peuvent ainsi être comparées entre-elles en se focalisant sur les facteurs d'intérêt toutes choses maintenues le plus possible égales par ailleurs. Un travail particulier de mise en place des protocoles a néanmoins permis de maintenir une tâche assez naturelle afin de ne pas induire des productions trop artificielles. Les deux premières études se sont intéressées à la production conjointe de gestes manuels et de parole contenant de la focalisation. Plusieurs types de gestes ont été comparés (geste de pointage, geste de battement et geste d'appui sur un bouton) lors d'une tâche de désignation. Il a été montré que la production de focalisation attire le geste manuel quel que soit son type mais que l'attraction est plus " précise " et fine pour le pointage. Par ailleurs, l'apex du geste de pointage semble être cooccurent à une cible articulatoire plutôt qu'acoustique. La seconde étude manipule le lien de désignation le geste de pointage et la parole. Elle montre, en exhibant deux stratégies adoptées par les participants, la complexité des mécanismes mis en jeu dans cette coordination. Finalement, une troisième étude s'intéresse à la coordination dans une tâche interactive et collaborative plus naturelle. Dans cette tâche les locuteurs utilisent naturellement des gestes de pointage pour désigner à leur interlocuteur l'emplacement d'une carte à poser grâce à une phrase porteuse contenant un démonstratif. Les résultats montrent une cooccurrence de la partie du geste qui montre avec l'information qui lui est complémentaire en parole, i.e. avec le nom de l'objet à poser à l'endroit désigné par le geste de pointage, plutôt qu'avec la partie de la parole qui désigne, i.e. le démonstratif. L'effet de la perturbation de l'interaction par un bruit ambiant est également testé et il est montré que, si la parole subit un effet Lombard classique, la production de gestes est peu modifiée mis à part une adaptation de la durée de la partie du geste qui montre à l'allongement de la parole. Ce mémoire propose par ailleurs une exploration des procédés d'annotation multimodaux mis en place pour l'annotation de tâches semi-contrôlées mais applicables à des cas plus généraux. Le manuscrit se conclut par une mise en perspective des résultats pour l'amélioration de certains modèles de production conjointe gestes manuels/parole et fournit quelques pistes utilisables dans le domaine des agents conversationnels ainsi que pour la détection de pathologies.

Résumé :
A central issue in the study of primate communication is the extent to which individuals adjust their behaviour to the attention and signals of others, and manipulate others’ attention to communicate about external events. I investigated whether 13 chimpanzees (Pan troglodytes spp.), 11 bonobos (Pan paniscus), and 7 orangutans (Pongo pygmaeus pygmaeus) followed conspecific attention and led others to distal locations. Individuals were presented with a novel stimulus, to test if they would lead a conspecific to detect it in two experimental conditions. In one the conspecific faced the communicator, while another required the communicator to first attract the attention of a conspecific. All species followed conspecific attention, but only bonobos in conditions that required geometric attention following and that the communicator first attract the conspecific‘s attention. There was a clear trend for the chimpanzees to selectively produce a stimulus directional ‘hunching’ posture when viewing the stimulus in the presence of a conspecific rather than alone (the comparison was statistically non-significant, but very closely approached significance [p = 0.056]), and the behaviour consistently led conspecifics to look towards the stimulus. An observational study showed that ‘hunching’ only occurred in the context of attention following. Some chimpanzees and bonobos consistently and selectively combined functionally different behaviours (consisting of sequential auditory-stimulus-directional-behaviours), when viewing the stimulus in the presence of a non-attentive conspecific, although at species level this did not yield significant effects. While the design did not eliminate the possibility of a social referencing motive (“look and help me decide how to respond”), the coupling of auditory cues followed by directional cues towards a novel object, is consistent with a declarative and social referential interpretation of non-verbal deixis. An exploratory study, which applied the ‘Social Attention Hypothesis’ (that individuals accord and receive attention as a function of dominance) to attention following, showed that chimpanzees were more likely to follow the attention of the dominant individual. Overall, the results suggest that the paucity of observed referential behaviours in apes may owe to the inconspicuousness and multi-faceted nature of the behaviours.

Résumé :
Les gestes de pointage et le regard guidé sont couramment utilisés comme des indices corporels pour faciliter l'attention visuelle et la compréhension dans différents domaines académiques. Cependant, leur efficacité spécifique dans le contexte sportif, notamment dans l'enseignement des schémas tactiques de basket-ball, reste relativement peu explorée. L'objectif central de cette thèse était donc d'examiner l'impact des gestes de pointage et/ou du regard guidé de l'entraîneur sur l'attention visuelle et la mémorisation des scènes tactiques. Les principaux résultats essentiels ont révélé des interactions significatives entre l'utilisation de ces indices et le niveau d'expertise des joueurs, démontrant ainsi un effet de renversement de l'expertise. Dans la plupart des expériences menées, les méthodes pédagogiques efficaces pour les joueurs novices se sont avérées inefficaces, voire préjudiciables, pour les joueurs experts. Par conséquent, ces résultats soulignent l'importance de s'adapter aux variations du niveau d'expertise des joueurs lors de l'utilisation des gestes de pointage et/ou du regard guidé pour la présentation du matériel d'entraînement pour la présentation des plans et/ou phases de jeu en basket-ball
Pointing gestures and guided gaze are commonly used as bodily cues to enhance visual attention and comprehension in various academic domains. However, their specific effectiveness in the sports context, particularly in teaching basketball tactical patterns, remains relatively unexplored. Therefore, the central objective of this thesis was to examine the impact of pointing gestures and/or guided gaze by the coach on visual attention and memorization of tactical scenes. The key findings revealed significant interactions between the use of these cues and the players' level of expertise, demonstrating an expertise reversal effect. In most experiments conducted, pedagogical methods that were effective for novice players proved to be ineffective or even detrimental for expert players. Consequently, these results emphasize the importance of adapting the use of pointing gestures and guided gaze to accommodate variations in players' expertise level when presenting training materials for basketball game plans and/or phases

Résumé :
AbstractThis paper presents a brainstorming tool combined with pointing gestures to improve the brainstorming meeting experience for blind and visually impaired people (BVIP). In brainstorming meetings, BVIPs are not able to participate in the conversation as well as sighted users because of the unavailability of supporting tools for understanding the explicit and implicit meaning of the non-verbal communication (NVC). Therefore, the proposed system assists BVIP in interpreting pointing gestures which play an important role in non-verbal communication. Our system will help BVIP to access the contents of a Metaplan card, a team member in the brainstorming meeting is referring to by pointing. The prototype of our system shows that targets on the screen a user is pointing at can be detected with 80% accuracy.

Résumé :
For structuring spatial relations, Brazilian Portuguese has four basic deictic forms: “aqui” (nearer to the speaker), “aí” (nearer to the addressee), “ali” (near to both speaker and addressee), and “lá” (distal from both speaker and addressee), whereas American English has a two-way distinction, linguistically expressed by “here” (near to the speaker) and “there” (distal from both the speaker and the hearer). Considering these differences, we aim at investigating how manual gestures operate along with speech, to point out to referents both located in the immediate interactional scene, the Ground [1], and projected in a non-immediate scene, narrated by the speaker. To do so, we collected 60 videos [2], 10 for each deictic, from late-night talk shows broadcasted in Brazilian, as well as in American TV broadcasts. As we carried out a gestural form and function analysis, the Linguistic Annotation System for Gestures [3], was adopted, which provided categorization tools to describe and analyze the verbo-gestural compounds encompassing locative deictic expressions both in American English and in Brazilian Portuguese. Results from both languages data samples support the hypothesis that the most frequent gestures that go along with the verbally uttered deictic expression is the pointing gesture. However, Brazilian Portuguese speakers predominantly use Pointing with Index Finger, associated to more prototypical deictic uses [4]. On the other hand, American English speakers mostly use Pointing with Open Hand, which is more associated to abstract ideas related to the conversational topic [4]. Considering gesture functions, it was also supported the hypothesis that referential function was predominant in both data samples. However, when the referential function was divided into concrete and abstract, Brazilian Portuguese shows a predominance of abstract deictic [5] uses, locating objects or entities in the imagined narrative scene. American English shows a predominance of concrete referential uses, locating objects or entities on the immediate scene. Finally, when the use of the verbo-gestural compounds is related to the ICM of Deixis [6], the comparison between Brazilian Portuguese and American English datasets indicates a cognitive resemblance between both languages, even though the deictic spatial relations are linguistically established in different ways on the same discursive genre.

Résumé :
The paper examines hand gestures when referring to inanimate referents. The aim of the study was to explore which factors determine the features of a gesture within the framework of modes of representation. Four main types of modes of representation were considered: drawing or shaping the form of the referent, acting, pointing, and presentation (PUOH); in addition, a new category of beat gestures was added. As a result, it was shown that communicative dynamism or other referent characteristics such as control of the object or its inferability from the previous context do not fully determine the use of gestures with the referent. As an alternative hipothesis, we propose a notion of gesture information hierarchy, where discursive factors, such as previous mentions of the referent and the introduction or change of the protagonist along with the way an object is used determines the form of the gesture.

Résumé :
The article addresses the relation of referential expressions and co-occurring kinetic phenomena (hand and head gestures) on the material of the RUPEX multimodal corpus. The results reflect significant differences in how individual movements and gestures are aligned with two major types of reference (full NPs vs. reduced expressions). It was initially assumed that full NPs are more often accompanied by a gesture. Our data support this hypothesis not only through the material of hand gestures, but also through head movements. Moreover, full NPs are more likely to be accompanied by downward movements in both manual and cephalic channels, as well as by metadiscourse gestures, in comparison to reduced referential units (personal and demonstrative pronouns). In addition, pronouns are more likely to be aligned with pointing hand gestures and zero reference is often accompanied by descriptive hand gestures. However, the kinetic behavior of the interlocutors is determined by a variety of factors, including the topic of the conversation, which predisposes to certain types of gestures and the relative position of the interlocutors.
