Traces the development of an approach to studying face-to-face interaction that proposes to expound the rules or procedures of interaction and to account for observed behavior in terms of how it functions as a communicational system. A selective literature review and recommendations for further study are included. (EJS)

Compares the production of speech and sign: the approaches used in research, the cognitive processes involved, and the output timing mechanism. (AM)
