Chapter 9. Changes in turn-design over interactional histories – the case of instructions in driving school lessons

This paper studies how the turn-design of a highly recurrent type of action changes over time. Based on a corpus of video-recordings of German driving lessons, we consider one type of instructions and analyze how the same instructional action is produced by the same speaker (the instructor) for the same addressee (the student) in consecutive trials of a learning task. We found that instructions become increasingly shorter, indexical and syntactically less complex; interactional sequences become more condensed and activities designed to secure mutual understanding become rarer. This study shows how larger temporal frameworks of interpersonal interactional histories which range beyond the interactional sequence impinge on the recipient-design of turns and the deployment of multimodal resources in situ.
