This text presents a new model of conversation based on time, in this case referring both to the rhythmic organization of conversation, the tempo, and to the right time or timing. These two notions of time correspond to two major systems governing conversation: the turn taking system and the rapport system. This model interweaves linguists' work on spoken discourse, sociologists' work on conversation analysis, and psychologists' work on non-verbal communication. This volume also explores the evolution of the interview as a genre which creates a particular context for conversation. Gatekeeping interviews in particular are explored because of their dual nature-to guide and monitor individuals in an institution or business. They are routine, but essential factors in determining the future of individuals within these organizations. Finally, the volume shows the importance of the listener in conversation. No previous theory of discourse or conversation incorporates the notion of rapport, yet speakers clearly depend on listeners' response as cues for shaping their utterances.
