Facial emotion recognition in schizophrenia: an event-related potentials study.

Previous studies extensively reported an impaired ability to recognize emotional stimuli in patients with schizophrenia. We used pictures from Ekman and Friesen in an event-related potentials study to investigate the neurophysiological correlates of the fear emotional processing compared with happiness in patients with schizophrenia versus healthy subjects. A significant lower P300 amplitude for fear processing but not for P100, N170 and N250 amplitude was found in schizophrenics compared to controls. These data suggest that the ability of basic visual processing is preserved in schizophrenia, whereas facial affect processing is impaired.
