Abstract
The structure of speaker–auditor interaction during speaking turns was explored, using detailed transcriptions of language, paralanguage, and body-motion behaviors displayed by both participants in dyadic, face-to-face conversations. On the basis of certain observed regularities in these behaviors, three signals were hypothesized: (a) a speaker within-turn signal, (b) an auditor back-channel signal, and (c) a speaker continuation signal. These signals were composed of various behaviors in language and in body motion. It was further hypothesized that the display of appropriate ordered sequences of these signals by both participants, served to mark ‘units of interaction’ during speaking turns.
