Embodied Communication: Speakers' Gestures Affect Listeners' Actions
Cook, Susan Wagner; Tanenhaus, Michael K.
Cognition, v113 n1 p98-104 Oct 2009
We explored how speakers and listeners use hand gestures as a source of perceptual-motor information during naturalistic communication. After solving the Tower of Hanoi task either with real objects or on a computer, speakers explained the task to listeners. Speakers' hand gestures, but not their speech, reflected properties of the particular objects and the actions that they had previously used to solve the task. Speakers who solved the problem with real objects used more grasping handshapes and produced more curved trajectories during the explanation. Listeners who observed explanations from speakers who had previously solved the problem with real objects subsequently treated computer objects more like real objects; their mouse trajectories revealed that they lifted the objects in conjunction with moving them sideways, and this behavior was related to the particular gestures that were observed. These findings demonstrate that hand gestures are a reliable source of perceptual-motor information during human communication. (Contains 2 figures.)
