When more than one person talks simultaneously, overlaps happen. Overlapping talk is a ubiquitous phenomenon found in any speech exchange systems (cf., Schegloff, 2000). However, when it comes to the second language acquisition (SLA) research, overlapping talk has seldom been taken up as an object of investigation.

In this presentation, I will present my preliminary investigation of overlapping talk observed during pair work activities in elementary Japanese language classrooms at a U.S. university. The data come from a corpus of 67 video-recorded pair work cases. A conversation-analytic (CA) framework is used to closely examine the occurrences of overlapping talk on a turn-by-turn basis.

By drawing on the ‘unusual’ characteristics of overlapping talk found in the database, I will discuss whether or not these pair work activities afford opportunities for SLA.

Through this presentation, I would also like to discuss how CA, established by sociologists, such as Harvey Sacks and Emanuel Schegloff, can be applied to the analysis of L2 interaction data in order to advance our understanding of the SLA process.
