Any three of:
- no predetermined cognitive map
- collaboratively achieved
- managed on a turn-by-turn basis
- one-at-a-time talk
- highly coordinated
1 A [TCU he shows his fist to you does he?] [TRP]
2 B [TCU yeah] [TRP] [TCU he smoking all the time] [TRP]
3 A [TCU he’s smoking all the time] [TRP]
4 B [TCU yeah] [TRP]
5 A [TCU yeah I know] [TRP] [TCU but tell him off]
Extract B is an inadvertent overlap, as Sheilah commences her line 2 talk after the slight pause in Josie’s utterance. This slight pause can be seen as signaling a transition relevance place. Josie had apparently not completed her turn at talk, however, as she tags on the phrase or something like it.
Extract C is also an example of inadvertent overlap, as both Joe and Rob attempt to self-select as next speaker under turn allocation Rule 2. They do so at an appropriate transition relevance place that occurs at the end of Carl’s line 1 turn-constructional unit.
