Dynamic face processing impairments are associated with cognitive and positive psychotic symptoms across psychiatric disorders

Abstract Impairments in social cognition—including recognition of facial expressions—are increasingly recognised as a core deficit in schizophrenia. It remains unclear whether other aspects of face processing (such as identity recognition) are also impaired, and whether such deficits can be attribut...
