Although impairments in social cognition are a core feature in schizophrenia, the relationship between its subcomponents is less clear. Nineteen schizophrenia patients and 20 matched healthy controls were tested for emotion recognition, and for the cognitive and affective subcomponents of empathy and theory of mind (ToM). Patients scored significantly worse than controls on cognitive empathy and both subcomponents of ToM. Group differences disappeared for cognitive empathy and affective ToM when emotion recognition was included as a covariate. Our results indicate that emotion recognition is an important factor involved in the deficits on higher levels of social cognition in schizophrenia.
