Facial reactions in schizophrenic patients were assessed via electromyography (EMG) in response to pictures of facial expressions. Male patients and nonpatient controls viewed photographs of positive and negative facial expressions while EMG activity from the corrugator and zygomatic muscle regions was recorded. Both schizophrenic patients and controls exhibited greater zygomatic reactivity in response to positive pictures than in response to negative pictures and greater corrugator reactivity in response to negative pictures than in response to positive pictures. Schizophrenic patients exhibited greater corrugator reactivity than did nonpatient controls. Implications for understanding emotion expression and perception in schizophrenic patients are discussed.
通过肌电图（EMG）对精神分裂症患者对面部表情图片的反应进行了评估。男性患者和非患者对照观看正面和负面面部表情的照片，同时记录皱眉肌和颧肌区域的肌电活动。精神分裂症患者和对照在对正面图片的反应中比在对负面图片的反应中表现出更大的颧肌反应性，在对负面图片的反应中比在对正面图片的反应中表现出更大的皱眉肌反应性。精神分裂症患者比非患者对照表现出更大的皱眉肌反应性。文中讨论了对理解精神分裂症患者情绪表达和感知方面的意义。
