| Abstract: | Do hand gestures play a role in spatial cognition? This paper reviews literature addressing the roles of gestures in (1) expressing spatial information, (2) communicating about spatial information, and (3) thinking about spatial information. Speakers tend to produce gestures when they produce linguistic units that contain spatial information, and they gesture more when talking about spatial topics than when talking about abstract or verbal ones. Thus, gestures are commonly used to express spatial information. Speakers use gestures more in situations when those gestures could contribute to communication, suggesting that they intend those gestures to communicate. Further, gestures influence addressees' comprehension of the speech they accompany, and addressees also detect information that is conveyed uniquely in gestures. Thus, gestures contribute to effective communication of spatial information. Gestures also play multiple roles in thinking about spatial information. There is evidence that gestures activate lexical and spatial representations, promote a focus on spatial information, and facilitate the packaging of spatial information in speech. Finally, some of the observed variation across tasks in gesture production is associated with task differences in demands on spatial cognitive processes, and individual differences in gesture production are associated with individual differences in spatial and verbal abilities. In sum, gestures appear to play multiple roles in spatial cognition. Central challenges for future research include: (1) better specification of the mental representations that give rise to gestures, (2) deeper understanding of the mechanisms by which gestures play a role in spatial thinking, and (3) greater knowledge of the sources of task and individual differences in gesture production. |
