Even if schizophrenia is known to affect social interaction, reasons of such impairment remain unclear. Social motor coordination has been suggested as being an important embodiment of healthy social exchanges. Therefore, we examined whether social motor coordination is affected by schizophrenia. Investigating patients unintentionally and intentionally coordinated with control participants, we found that schizophrenia decreased intentional but not unintentional coordination. A model is proposed to describe and understand such impairments.
