Adults and children spontaneously produce gestures while they speak, and such gestures appear to support and expand on the information communicated by the verbal channel. Little research, however, has been carried out to examine the role played by gesture in the listener's representation of accumulating information. Do listeners attend to the gestures that accompany narrative speech? In what kinds of relationships between gesture and speech do listeners attend to the gestural channel? If listeners do attend to information received in gesture, (...) how is this information represented— is it 'tagged' as originating in the gestural channel? In this article research is described that addresses these questions. Results show that listeners do attend to information conveyed in gesture, when that information supplements or even contradicts the information conveyed by speech. And information received via gesture is available for retelling in speech. These results are taken to demonstrate that gesture is not taken by the listener to be epiphenomenal to the act of speaking, or a simple manual translation of speech. But they also suggest that the information conveyed in a discourse may be represented in a manner that is neither gesture nor language, although accessible to both channels. (shrink)

In Gesture and Thought he brings together years of this research, arguing that gesturing, an act which has been popularly understood as an accessory to speech, ...

David McNeill, a pioneer in the ongoing study of the relationship between gesture and language, here argues that gestures are active participants in both speaking and thinking. He posits that gestures are key ingredients in an “imagery-language dialectic” that fuels speech and thought. The smallest unit of this dialectic is the growth point, a snapshot of an utterance at its beginning psychological stage. In _Gesture and Thought,_ the central growth point comes from a Tweety Bird cartoon. Over the course of (...) twenty-five years, the McNeill Lab showed this cartoon to numerous subjects who spoke a variety of languages, and a fascinating pattern emerged. The shape and timing of gestures depends not only on what speakers see but on what they take to be distinctive; this, in turn, depends on the context. Those who remembered the same context saw the same distinctions and used similar gestures; those who forgot the context understood something different and changed gestures or used none at all. Thus, the gesture becomes part of the growth point—the building block of language and thought. _Gesture and Thought _is an ambitious project in the ongoing study of how we communicate and how language is connected to thought.

When asked to explain their solutions to a problem, both adults and children gesture as they talk. These gestures at times convey information that is not conveyed in speech and thus reveal thoughts that are distinct from those revealed in speech. In this study, we use the classic Tower of Hanoi puzzle to validate the claim that gesture and speech taken together can reflect the activation of two cognitive strategies within a single response. The Tower of Hanoi is a well‐studied (...) puzzle, known to be most efficiently solved by activating subroutines at theoretically defined choice points. When asked to explain how they solved the Tower of Hanoi puzzle, both adults and children produced significantly more gesture‐speech mismatches—explanations in which speech conveyed one path and gesture another—at these theoretically defined choice points than they produced at non‐choice points. Even when the participants did not solve the problem efficiently, gesture could be used to indicate where the participants were deciding between alternative paths. Gesture can, thus, serve as a useful adjunct to speech when attempting to discover cognitive processes in problem‐solving. (shrink)
