Gesture and language: Cross-linguistic and historical data from signed languages

Abstract: In this paper I explore the role of gesture in the development of signed languages. Using data from American Sign Language, Catalan Sign Language, French Sign Language, and Italian Sign Language, as well as historical sources describing gesture in the Mediterranean region, I demonstrate that gesture enters the linguistic system via two distinct routes. In one, gesture serves as a source of lexical and grammatical morphemes in signed languages. In the second, elements become directly incorporated into signed language morphology, bypassing the lexical stage. Finally, I propose a unifying framework for understanding the gesture-language interface in signed and spoken languages.

Gestural phrases and gestural exchanges by a pair of zoo-living lowland gorillas

Abstract: Previous study of the spontaneous gestural communication of the great apes has been primarily of individual gestures and their sequels. Such analysis gives only a partial picture of the quality of gorilla interaction. The repertoire of gestures of a pair of gorillas at San Francisco Zoo have been described by Tanner and Byrne (1993, 1996, 1999). These gorillas often used gestures in continuous sequences or phrases. Both single gestures and phrases were used in exchanges between gorillas. Phrases included a variety of syntactic functions, and exchanges seemed to negotiate matters such as location, initiator, and type of play. Both single gestures and phrases could be modified by “negative’ gestures. Detailed transcription of gorilla communicative events show that gestures are continually being modified and varied by the communicative partners, rather than being ritualized elements of a finite repertoire.The electronic edition of this article includes audio-visual data.

Gesture and right hemisphere involvement in evaluating lecture material

Abstract: This study investigated hemispheric lateralization in comprehending and evaluating lecture material with and without nonverbal hand gestures. Participants watched a lecture with and without gesture under conditions of cognitive load in the left or right hemisphere. There were no effects of gesture or load on lecture comprehension, but gesture and load influenced how participants evaluated the lecture. Specifically, presence of gesture significantly influenced participants’ affective evaluations of the lecturer in both load conditions. However, gesture influenced cognitive evaluations of the lecture material only when the right hemisphere was free from cognitive load. The results suggest that the right hemisphere may be specialized for processing information conveyed through hand gestures.

Real space blends in spoken language: Evidence from “Mr. Roberts”

Abstract: In analyzing the use of space in American Sign Language (ASL), Liddell (2003) argues convincingly that no account of ASL can be complete without a discussion of how linguistic signs and non-linguistic gestures and gradient phenomena work together to create meaning. This represents a departure from the assumptions of much of linguistic theory, which has attempted to describe purely linguistic phenomena as part of an autonomous system. It also raises the question of whether these phenomena are peculiar to ASL and other sign languages, or if they also apply to spoken language. In this paper, I show how Liddell’s approach can be applied to English data to provide a fuller explanation of how speakers create meaning. Specifically, I analyze Jack Lemmons’ use of space, gesture, and voice in a scene from the movie “Mr. Roberts”.
