Abstract:

The age-old debate between the proponents of the gesture-first and speech-first positions has returned to occupy a central place in current language evolution theorizing. The gestural scenarios, suffering from the problem known as “modality transition” (why a gestural system would have changed into a predominantly spoken system), frequently appeal to the gestures of the orofacial area as a platform for this putative transition. Here, we review currently available evidence on the significance of the orofacial area in language evolution. While our review offers some support for orofacial movemen

Abstract:

Abstract We examined gesture representation of motion events in narratives produced by three- and nine-year-olds, and adults. Two aspects of gestural depiction were analysed: how protagonists were depicted, and how gesture space was used. We found that older groups were more likely to express protagonists as an object that a gesturing hand held and manipulated, and less likely to express protagonists with whole-body enactment gestures. Furthermore, for older groups, gesture space increasingly became less similar to narrated space. The older groups were less likely to use large gestures or gest

Abstract:

Unruly gestures presents a hybrid performative intervention by means of video, text, and still images. With this experimental essay we aspire to break down various preconceptions about reading/writing gestures. Breaking away from a narrative that sees these gestures foremost as passive entities – as either embodiments of pure subjective intentionality, or as bodily movements shaped and controlled by media technologies (enabling specific sensory engagements with texts) – we aim to reappraise them. Indeed, in this essay we identify numerous dominant narratives that relate to gestural agency, to

Abstract:

We have argued that dynamically defined articulatory gestures are the appropriate units to serve as the atoms of phonological representation. Gestures are a natural unit, not only because they involve task-oriented movements of the articulators, but because they arguably emerge as prelinguistic discrete units of action in infants. The use of gestures, rather than constellations of gestures as in Root nodes, as basic units of description makes it possible to characterise a variety of language patterns in which gestural organisation varies. Such patterns range from the misorderings of disordered

Abstract:

The gestures that accompany improvisation in Indian vocal music, like the gestures that accompany speech, are closely co-ordinated with vocalization. Though linked to what is being sung, these movements are not determined by vocal action; nor are they taught explicitly, deliberately rehearsed, or tied to specific meanings. Students tend to gesture recognizably like their teachers, producing lineage-based gesture dialects, but the gestural repertoire of every vocalist is nonetheless idiosyncratic.

The emergence of gesture based controls like the Microsoft Kinect provides new opportunities for creative and innovative methods of human computer interaction. However, such devices are not without their limitations. The gross-motor movements of gestural interaction present physical limitations that may negatively affect interaction speed, accuracy, and workload, and subsequently affect the design of system interfaces and inputs. Conversely, interaction methods such as eye tracking require little physical effort, leveraging the unconscious and natural behaviors of human eye-movements as inputs

Abstract:

During the second half of the 19th century, the psychology of language was invented as a discipline for the sole purpose of explaining the evolution of spoken language. These efforts culminated in Wilhelm Wundt's monumental Die Sprache of 1900, which outlined the psychological mechanisms involved in producing utterances and considered how these mechanisms could have evolved. Wundt assumes that articulatory movements were originally rather arbitrary concomitants of larger, meaningful expressive bodily gestures.

One advantage of using Articulatory Phonology (henceforth ArtP), with its basic units of abstract gestures based on articulatory movements, is its ability to link phenomena previously seen as phonological to those which are conventionally described as allophonic, or even lower-level phonetic effects, since ‘gestures are... useful primitives for characterising phonological patterns as well as for analysing the activi

Abstract:

Given a certain number of basic signs (gestural lexical items), the lexicon of a sign language can expand by modifying the morphology of its basic items. The case I present here concerns only those data where morphological modification is exploited as a lexical branching device, i.e., where a sign acquires a new signification but no additional, morphemes after undergoing such a modification, and the root form of that sign retains its original, meaning.The movement parameter is the principal device of an intrinsic nature for lexical branching in sign languages. In this respect, the movement mod

Abstract:

The gesture segmentation is a method that distinguishes meaningful gestures from unintentional movements. Gesture segmentation is a prerequisite stage to continuous gesture recognition which locates the start and end points of a gesture in an input sequence. Yet, this is an extremely difficult task due to both the multitude of possible gesture variations in spatio-temporal space and the co-articulation/movement epenthesis of successive gestures. In this paper, we focus our attention on coping with this problem associated with continuous gesture recognition. This requires gesture spotting that

Abstract:

Abstract Gestures, particularly pointing, are regarded as important pre-speech acts. Intentional and referential pointing has been shown previously in humans and apes but not in songbirds, although some avian species show cognitive abilities rivaling those of apes, and their brain structures and functions show putative preconditions for referential gestural signaling (i.e. mirror neurons, links of vocal learning nuclei to discrete brain areas active during limb and body movements). The results reported are based on trials testing predator detection and responses to a taxidermic model of a wedg

Abstract:

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 a

AbstractThis paper discusses how point of view (POV) is expressed in British Sign Language (BSL) and spoken English narrative discourse. Spoken languages can mark changes in POV using strategies such as direct/indirect discourse, whereas signed languages can mark changes in POV in a unique way using “role shift”. Role shift is where the signer “becomes” a referent by taking on attributes of that referent, e.g. facial expression. In this study, two native BSL users and two native British English speakers were asked to tell the story “The Tortoise and the Hare”. The data were then compared to se

For Laban and Wigman, gesture mirrors a vitalist understanding of life that is based on the rediscovery of transhistorical continuities between human and cosmic energy. Benjamin's Brechtian gestures address inscriptions and manipulations of bodies, which provide comment on the conditions of society by subjecting to critique the essentializing aspects of historical and vitalist flow.

This paper reports on a research project in mathematics education involving the use of gesture, movement and vocal sound to highlight mathematically salient features of the graphs of polynomial functions. Empirical observations of students’ spontaneous gesture types when enacting elicited gestures of these graphs reveal a number of useful binaries (proximal/distal, being the graph/seeing the graph, within sight/within reach). These binaries inform an analysis of videotaped gestural and interview data and appear to predict teachers’ assessments of student mathematical engagement and understandi
