精神分裂症患者在感知情感材料方面存在问题;然而，缺陷的特异性，程度和性质尚不清楚。面部情感和情感韵律识别进行了检查，在代表性样本的个人首次发病的精神病，评估为门诊病人在疾病的早期恢复阶段，和非患者。选择知觉任务，以允许检查的情绪类别的结果，在面对和声音的方式。面部任务是Feinberg等人程序的计算机化修改（Feinberg，T.E.，Rifkin，A.，Schaffer，C.，步行者，E.，1986. Arch. Gen. Psychiatry 43，276-279）。韵律任务的开发使用四个专业演员，和项目的选择是基于大学生的反应。参与者群体在对描述情绪的词汇的理解上没有差异。研究结果支持小，但一致的赤字识别恐惧和悲伤的两个沟通渠道的合并精神分裂症（n = 29）和其他精神障碍（n = 28）组相比，情感性精神病（n = 23）和非患者（n = 24）。诊断效果是明显的，是独立的智力的贡献。在首发精神分裂症患者中检测到情感识别障碍表明存在特质缺陷。结果的模式与精神分裂症和相关精神病的杏仁核功能障碍一致。
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.
