| Abstract: | A group of individuals conversing in natural dyads and a group of lecturers were observed for lateral hand movement patterns during speech. Right-handed individuals in both groups displayed a significant right hand bias for gesture movements but no lateral bias for self-touching movements. The study provides external validity for previous laboratory studies of lateralized hand gesture. The results were interpreted as evidence of a central processor for both spoken and gestural communication. |
