This chapter describes three general ways that participants arrive at a place where conversation stops. It first describes how the Sacks, Schegloff, and Jefferson turn-taking system produces lapses, and points out several deficiencies in the model. The analysis examines a range of situations and activities where conversation lapses, and divides them into three main types: lapses as the relevant cessation of talk, lapses as allowable silence, and lapses as the conspicuous absence of talk. In the course of the analysis and in the discussion, the chapter addresses the matter of gaps versus lapses, the importance of bodily conduct and activities, and the relationship of lapses to turn-taking and sequence organization.
