Focusing Attention with Deictic Gestures and Linguistic Expressions

Abstract

Comprehension and production of text and discourse do not solely depend on linguistic expressions, but also on the physical context.The questions addressed in this study are 1) whether deictic gestures are substitutable for deictic expressions, and 2) whether deictic gestures establish joint attention.An eye tracking experiment investigated the effect of referring expressions and gestures on various aspects of attention.Results indicated that deictic gestures substitute for location descriptions.Furthermore, the manipulation of the synchrony between gesture and speech showed that hearers benefit from focusing of visual attention.
