Gesture, self-repair and reasoning in schizophrenia

Successful social encounters require mutual understanding between interacting partners, and patients with schizophrenia are known to experience difficulties in social interaction. We present some data from discussions of the balloon task that show that during social interaction, schizophrenia patients repair their own speech less, and come up with fewer arguments regarding who to throw out of the balloon. In addition, although increased hand gesture is correlated with increased self-repair in healthy controls, there is no such association in patients with schizophrenia, or their interlocutors. This suggests that multimodal and reasoning impairments are not merely seen on an individual level but may be a feature of patients' social encounters.
