Individuals with schizophrenia experience problems in the perception of emotional material; however, the specificity, extent, and nature of the deficits are unclear. Facial affect and affective prosody recognition were examined in representative samples of individuals with first-episode psychosis, assessed as outpatients during the early recovery phase of illness, and non-patients. Perception tasks were selected to allow examination of emotion category results across face and voice modalities. Facial tasks were computerised modifications of the Feinberg et al. procedure (Feinberg, T.E., Rifkin, A., Schaffer, C., Walker, E., 1986. Arch. Gen. Psychiatry 43, 276--279). Prosody tasks were developed using four professional actors, and item selections were based on responses of undergraduates. Participant groups did not differ in their understanding of the words used to describe emotions. Findings supported small but consistent deficits in recognition of fear and sadness across both communication channels for the combined schizophrenia (n=29) and other psychotic disorders (n=28) groups as compared to the affective psychoses (n=23) and non-patients (n=24). A diagnostic effect was evident that was independent of the contribution of intelligence. The detection of emotion recognition impairments in first-episode schizophrenia suggests a trait deficit. The pattern of results is consistent with amygdala dysfunction in schizophrenia and related psychoses.
精神分裂症患者在情感材料感知方面存在问题；然而，这些缺陷的特异性、程度和性质尚不清楚。我们对首次发作精神病患者的代表性样本、在疾病早期康复阶段作为门诊患者接受评估的患者以及非患者进行了面部表情和情感韵律识别研究。选择感知任务以考察跨面部和语音模态的情感类别结果。面部任务是对Feinberg等人方法（Feinberg, T.E., Rifkin, A., Schaffer, C., Walker, E., 1986. Arch. Gen. Psychiatry 43, 276 - 279）的计算机化修改。韵律任务由四名专业演员完成，项目选择基于大学生的反应。参与者群体在对用于描述情感的词汇理解上没有差异。研究结果支持，与情感性精神病患者（n = 23）和非患者（n = 24）相比，精神分裂症合并其他精神障碍患者组（n = 29）在通过两种交流渠道识别恐惧和悲伤方面存在虽小但一致的缺陷。存在一种独立于智力因素的诊断效应。首次发作精神分裂症中情感识别障碍的发现表明存在特质缺陷。结果模式与精神分裂症及相关精神病中的杏仁核功能障碍一致。
