Konferensbidrag (refereegranskat)abstract
- Research on co-speech gestures has primarily focussed on speakers. However, in conversation non-speaking addressees can also gesture. Often this is to provide concurrent feedback such as backchannels but sometimes it involves gestures that relate to the specific content of the speaker's turn. We hypothesise that non-speakers should contribute most actively during clarification sequences i.e. at the moments when mutual-understanding is threatened. We test this hypothesis using a corpus of story-telling dialogues, captured using video and motion capture. The results show that during clarification sequences speaker and non-speaker behaviours tend to merge. Non-speakers in particular move their hands faster and produce more than twice as many content-specific specific gestures in overlap with speaker turns. These results underline the collaborative nature of conversation, the strategic importance of non-verbal resources for sustaining mutual-understanding and the critical role of clarification and repair in successful communication.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Social exclusion and social dysfunction are persistent and debilitating aspects of schizophrenia. The interactional impact of patients’ social deficits during actual dialogue is poorly understood. Through analysis of a corpus of patients’ triadic interactions we explored laughter as a marker of discomfort or coalition in patients’ interactions. Patient interactions did not differ from controls in terms of laughter production. However, patients who were more symptomatic laughed less frequently, while their partners showed a trend for displaying more shared laughter, potentially indicating coalition formation.

Bokkapitel (refereegranskat)abstract
- More accurate non-participatory parameters and psychoacoustics to assess human perceptual responses to the acoustic environment are critical to inform effective urban sound planning and applied soundscape practice. Non-participatory observation methods are widely used by experts to capture animal behavior. In 2012, Lavia and Witchel applied these principles and methodologies for the first time to capturing and assessing human behavior “in the wild” to changes to the acoustic environment using added sound and music interventions in a clubbing district. Subsequent work was conducted with Aletta and Kang and Healey, Howes, Steffens, and Fiebig to begin characterizing the acoustic environment and human responses to align the perceptual and physical findings. Here, the authors report on new work and analysis and propose a preliminary predictive agile applied soundscape framework using non-participatory observation methods and psychoacoustics to be used with environmental assessment practice and evolving urban soundscape planning methods by researchers, practitioners, and policy makers.
