Disfluency and behaviour in dialogue: evidence from eye-gaze

Previous research on disfluency types has focused on their distinct cognitive causes, prosodic patterns, or effects on the listener. This paper seeks to add to this taxonomy by providing a psycholinguistic account of the dialogue and gaze behaviour speakers engage in when they make certain types of disfluency. Dialogues came from a version of the Map Task, [2, 4], in which 36 normal adult speakers each participated in six dialogues across which feedback modality and time-pressure were counter-balanced. In this paper, we ask whether disfluency, both generally and type-specifically, was associated with speaker attention to the listener. We show that certain disfluency types can be linked to particular dialogue goals, depending on whether the speaker had attended to listener feedback. The results shed light on the general cognitive causes of disfluency and suggest that it will be possible to predict the types of disfluency which will accompany particular behaviours.
