Prior studies provide consistent evidence of deficits for psychopaths in processing verbal emotional material but are inconsistent regarding nonverbal emotional material. To examine whether psychopaths exhibit general versus specific deficits in nonverbal emotional processing, 34 psychopaths and 33 nonpsychopaths identified with Hare's (R. D. Hare, 1991) Psychopathy Checklist--Revised were asked to complete a facial affect recognition test. Slides of prototypic facial expressions were presented. Three hypotheses regarding hemispheric lateralization anomalies in psychopaths were also tested (right-hemisphere dysfunction, reduced lateralization, and reversed lateralization). Psychopaths were less accurate than nonpsychopaths at classifying facial affect under conditions promoting reliance on right-hemisphere resources and displayed a specific deficit in classifying disgust. These findings demonstrate that psychopaths exhibit specific deficits in nonverbal emotional processing.
先前的研究一致证明，精神病患者在处理言语情感材料方面存在缺陷，但在非言语情感材料方面的研究结果并不一致。为了检验精神病患者在非言语情感处理中表现出的是普遍缺陷还是特定缺陷，我们让34名精神病患者和33名根据哈雷（R.D.哈雷，1991）的《精神病态核查表修订版》确定的非精神病患者完成一项面部表情识别测试。测试中展示了典型面部表情的幻灯片。我们还检验了关于精神病患者半球侧化异常的三个假设（右半球功能障碍、侧化减弱和侧化逆转）。在促进依赖右半球资源的条件下，精神病患者在对面部表情进行分类时不如非精神病患者准确，并且在对厌恶表情进行分类时表现出特定缺陷。这些发现表明，精神病患者在非言语情感处理中存在特定缺陷。
