How are speech and gesture related?

چکیده
People gesture when they speak. Despite considerable attention from a variety of disciplines, the precise nature of the relation between gesture, speech and thought has remained elusive. The research reported here considers two very different hypotheses about the fundamental relationship. By one account, gesture is a consequence of physiological arousal. By another account, gesture use reflects more cognitive processes and is strongly linked to mental representation. This paper seeks the mechanism underlying the link between gesture and speech by showing that both mental representation and physiological arousal are reflected in our gesture use.

Exploring the speech-gesture semantic continuum

However, the relationship between the meaning of speech and the meaning of gesture can di↵er. Several terms have been used to specify these di↵erent relationships, ranging from “redundant” over “supplemental” to “mismatching” information. No consensus about the exact ...
متن کاملGestures Augment Learning in Communicators and Recipients
Communicators explained how to assemble an object or how to get from A to B to recipients, using speech and gesture freely, or restricted to gesture alone. Explanations were examined for uses of gesture and speech in conveying semantic content as well as narrative structure. For both tasks, communicators who explained using only gestures performed better than those using gestures and speech. Re...
متن کاملDoes language shape silent gesture?
Languages differ in how they organize events, particularly in the types of semantic elements they express and the arrangement of those elements within a sentence. Here we ask whether these cross-linguistic differences have an impact on how events are represented nonverbally; more specifically, on how events are represented in gestures produced without speech (silent gesture), compared to gestur...
متن کاملAn investigation of co-speech gesture production during action description in Parkinson's disease.
INTRODUCTION Parkinson's disease (PD) can impact enormously on speech communication. One aspect of non-verbal behaviour closely tied to speech is co-speech gesture production. In healthy people, co-speech gestures can add significant meaning and emphasis to speech. There is, however, little research into how this important channel of communication is affected in PD. METHODS The present study ...
متن کاملCoexpressivity of speech and gesture: Lessons for models for aligned speech and gesture production
When people combine language and gesture to convey their intended information, both modalities are characterized by an intriguing degree of coherence and consistency. For developing an account how speech and gesture are aligned to each other, one question of major importance is how meaning is distributed across the two channels. In this paper, we start from recent empirical findings indicating ...
