This paper discusses the present special issue on “Communication Viewed from Hearers' Behaviors,” focusing on Erving Goffman's participation framework and gestural phenomena observed in conversation. In particular, it points out the possibility to conceive of speaker as a) a hearer, b) a receiver of the information, as well as c) an addressee. It also points out that grand gesture and simultaneous gestural matching can be loci of analysis in understanding how social-interactional plain and cognitive plain interact in investigatory conversation between the suspect and the policemen and⁄or prosecutory officials, and in psychological counseling.
