Deficits in the perception of facial emotion have been demonstrated in patients with right-sided brain damage (RBD) and schizophrenia (SZ). Furthermore, recent speculations have implicated right-hemisphere dysfunction in Type II schizophrenics, especially those with a preponderance of "negative symptoms" and flat affect. The performance of SZ, RBD, and normal control subjects was compared on measures assessing facial emotional perception. Both identification and discrimination paradigms were used, with positive/pleasant and negative/unpleasant emotions. To examine the effects of visuospatial and facial processing on facial emotion tasks, the Visual Matrices Test and the Benton Facial Recognition Test were administered. On both facial emotion tests, SZ and RBD patients were significantly impaired relative to normal subjects, but not different from each other. The SZ and RBD patients were also impaired on the matrices and facial recognition tests. When the effects of the matrices and neutral face recognition tests were statistically controlled, significant group differences remained for the identification task but not for the discrimination task. Thus, methodologies are presented for the neuropsychological study of facial emotional perception, and some support is provided for the notion that negative-symptom schizophrenia is associated with right hemisphere dysfunction.
右侧脑损伤（RBD）患者和精神分裂症（SZ）患者已被证实存在面部情绪感知缺陷。此外，最近的推测表明，II型精神分裂症患者，尤其是那些以“阴性症状”和情感平淡为主的患者，存在右半球功能障碍。比较了SZ、RBD患者和正常对照受试者在评估面部情绪感知的测量指标上的表现。使用了识别和辨别范式，涉及积极/愉悦和消极/不愉快情绪。为了研究视觉空间和面部处理对面部情绪任务的影响，进行了视觉矩阵测试和本顿面部识别测试。在两项面部情绪测试中，SZ和RBD患者相对于正常受试者均有显著损伤，但彼此之间无差异。SZ和RBD患者在矩阵测试和面部识别测试中也表现受损。当对矩阵测试和中性面部识别测试的影响进行统计控制后，识别任务仍存在显著的组间差异，而辨别任务则不存在。因此，本文介绍了用于面部情绪感知神经心理学研究的方法，并为阴性症状精神分裂症与右半球功能障碍相关这一观点提供了一些支持。
