Abstract
Objectives : Schizophrenia has been considered to be characterized by an abnormality in attention, especially in the executive control. Emotion is an important component of the executive control. The aim of this study was to investigate the influence of emotion on the executive control in patients with schizophrenia. Methods : Participants were 20 healthy controls and 19 subjects with schizophrenia. They viewed full-color pictures selected from the International Affective Picture System. During each trial, an emotional picture, which was either positive or negative, lit up on either the left or right side. Participants were instructed to respond to the emotional valance of each stimulus by pressing a button with their left or right index finger, while ignoring its presented side. Results : There was a group difference in the response time, and patients with schizophrenia exhibited an impairment in the executive control of emotional information. However, there was no difference in the response time between the emotional conditions. In the patient group, the missing rate in the positive emotional condition was correlated with the severity of social anhedonia, whereas the missing rate in the negative emotional condition was correlated with the severity of positive symptoms. Conclusion : Patients with schizophrenia have a deficit in the executive control of positive emotional information as well as negative emotion, but it may be due to different underlying mechanisms.
