Eyebrow raising in dialogue : discourse structure, utterance function, and pitch accents
This thesis investigated eyebrow raising in a small corpus of task oriented English dialogues. Applying a standard dialogue coding scheme (Conversational Game Analysis, Carletta et al. 1997), eyebrow raises were studied in connection with discourse structure and utterance function. Supporting the prediction, more frequent and longer eyebrow raising occurred in the initial utterance of high level discourse segments (<i>transactions)</i> (utterance = â<i>moveâ</i> in Carletta et al.) than anywhere else in the dialogue. Additionally, eyebrow raises were more frequent in instructions than in requests for or acknowledgements of information. Instructions had also longer eyebrow raising than any other type of utterance. The start of a lower discourse level (<i>conversational game)</i>, and queries, did not have more frequent or longer eyebrow raising than any other position in the dialogue and any other type of utterance, respectively. In order to explore their location inside utterances eyebrow raises were also studied in relation to intonational events, namely pitch accents. Results showed evidence of alignment between the two events (the brow raise start and the pitch accent start). On average, eyebrow raises
