Turn-taking

Sidnell's article "Conversational Turn-taking in a Caribbean English Creole" gave me much food for thought regarding conversation analysis. Specifically the specialized vocabulary. I'm going to attempt to give examples of some of these vocab/concepts.

TCU - turn constructional unit - seems to be the 'atom' of turn-taking from which the dialectic of conversation is constructed.

Here are two TCUs:
A: Did ya see the show?
B: Unbelievable!

TRP or 'transition relevance point' = a projected point of possible completion of a TCU.
Here B interprets A's completion of 1 TCU as a TRP, leading to an interruption as A intended to continue with another TCU.

A: Sue and I went to the aquarium. We saw...
B:                                               [Billy and I went there yesterday

Because B began without A selecting them to be the next speaker, B 'self-selects' themselves as the next speaker.

If I don't want to be interrupted, I need to come up with strategies for showing that I intend on taking a turn consisting of multiple TCUs.
