- 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.

- Patients with schizophrenia are known to have difficulties in reasoning, but previous work has not looked at how such deficits manifest in face-to-face interactions. Using a unique cor- pus of triadic interactions discussing a moral dilemma, half of which involve a patient with schizophrenia, we show that patients are more likely than their interlocutors and control groups to provide arguments which reject the constraints of the task. Patients are also more likely to be consistent in their reasoning across a dialogue than their interlocutors or controls. Our results suggest that patients do not have impaired reasoning abilities but rather reason on the basis of a different view of the task than non-patients.

The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project

Tidskriftsartikel (refereegranskat)abstract
- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Are we having a laugh? Conversational laughter in schizophrenia
- 2018
-
Ingår i: Proceedings of the Workshop on Dialogue and Perception, Gothenburg, 14–15 June 2018.

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.
