Gestural cues for turn management in interactions

This study sought to determine the contribution of gestures in interactions. We focus on the transition of the speaker’s gaze direction as a gestural cue for turn management. Sacks et al. (1974) proposed turn-constructional units (TCUs) for structuring turns. An important characteristic of the unit is its projectability, that is, the features that allow participants to anticipate where the unit will come to an end. It is possible for participants to perceive the potential points of transition relevance places (TRPs). We statistically analyzed the correlations between gaze shift timing, syntactic forms, and post-utterance pause length at turn endings in Japanese poster session conversations. The results show that when the utterance endings are not syntactically determined to be complete, the feature of gaze shift timing is needed to show whether the utterance ending is complete in Japanese conversation. Verb-fi nal languages like Japanese does not have high syntactic projectability at the beginning of turns compared to non-verb-fi nal languages such as English. Whether the utterance is complete or continued is partially determined by the syntactic form of an utterance ending in Japanese. We concluded that speakers effectively use gaze cues to indicate to the hearers the possible points of TRPs in Japanese interactions.
