Book excerpt: The present volume is an excellent introduction to the study of human nonverbal communication, including interaction and gesture, for students and specialists in other disciplines, as well as a convenient compilation of significant contributions to the field for experts. Part 1 includes four articles, the import of which is primarily theoretical or methodological. Part II comprises eight articles in which instances of interaction are examined and attempts are made to explain how the behavior that can be observed in them functions in the interaction process. Part III presents six articles on what may broadly be referred to as 'gesture'. These articles deal with specific actions, mostly of the forelimbs, which are usually deemed to have specific communicational significance. In an introductory chapter, the volume editor, Adam Kendon, not only examines the various issues raised by the eighteen papers but also shows the relevance of each article as a contribution to the development of an understanding of how human visible behavior functions communicatively.
