title: Schizophrenia and processing of facial emotions: sex matters.
abstract: The aim of this study was to examine sex differences in emotion processing in patients with schizophrenia and control subjects. To this end, 53 patients with schizophrenia (28 men and 25 women), and 42 controls (21 men and 21 women) were assessed with the use of a facial affect recognition morphing task. Accuracy and sensitivity scores were measured. Women performed better than men in labelling negative emotions. On the same task, patients performed worse than control subjects, irrespective of sex, although the largest degree of impairment was seen in male patients. In conclusion, emotion perception was disproportionally affected in men with schizophrenia relative to women. This may explain, in part, why women with schizophrenia are less impaired in social life than men suffering from this illness.
