Abstract
Background: Discrepancies in the ability to recognize faces constitute an important aspect of the impaired social cognitive abilities of patients with schizophrenia. Previous studies have suggested that specific problems with the processing of facial configuration affect the face-recognition deficit in patients with schizophrenia. However, little is known about whether these deficits in face recognition are present before the onset of schizophrenia. Method: This study compared performances on a face processing task among three groups: individuals at ultra-high risk for schizophrenia (n = 20), patients with schizophrenia (n = 18), and normal controls (n = 20) using a face-discrimination task involving pairs of photographs depicting upright and inverted images with changing features and configurations. Chair stimuli were used as the control task. Results: The individuals at ultra-high risk for schizophrenia performed more poorly than did normal controls with regard to the processing of facial configuration but not the facial feature and did not differ significantly from the patients with schizophrenia with regard to the processing of facial configuration and upright facial features. Conclusion: This study suggests that a specific dysfunction in the processing of facial configuration, which has an impact on face recognition, might be present before and deteriorate in patients with schizophrenia. Deficits in face recognition among individuals at risk for psychosis might contribute significantly to the social dysfunction associated with schizophrenia. (C) 2010 Elsevier B.V.
