Individuals with schizophrenia reportedly demonstrate deficits in emotion perception. Relevant studies on the effects of decoder's sex, communication channels and emotion categories have produced mixed findings and seldom explored the interactions among these three key factors. The present pilot study examined how male and female individuals with schizophrenia and healthy controls perceived emotional (e.g., angry, happy, and sad) and neutral expressions from verbal semantic and nonverbal prosodic and facial channels. Twenty-eight (11 females) individuals with schizophrenia and 30 healthy controls (13 females) were asked to recognize emotional facial expressions, emotional prosody, and emotional semantics. Both accuracy and response time showed subpar performance for all communication channels and emotional categories in the schizophrenia group. More severe emotion perception deficits were found with the nonverbal (not the verbal) materials. There was also a reduced level of impairment with anger perception, especially in the female individuals with schizophrenia while biased perception towards emotional semantics was more pronounced in male individuals with schizophrenia. These findings, although preliminary, indicate the channel- and category-specific nature of emotion perception with potential sex differences among people with schizophrenia, which has important theoretical and practical implications.
据报道，精神分裂症患者在情绪感知方面存在缺陷。关于解码器性别、沟通渠道和情绪类别对情绪感知的影响的相关研究得出的结果喜忧参半，很少有研究探讨这三个关键因素之间的相互作用。本初步研究探讨了男性和女性精神分裂症患者以及健康对照组如何从言语语义、非言语韵律和面部通道感知情绪（如愤怒、快乐和悲伤）和中性表情。要求 28 名（11 名女性）精神分裂症患者和 30 名健康对照组（13 名女性）识别情绪面部表情、情绪韵律和情绪语义。在所有沟通渠道和情绪类别中，精神分裂症组的准确性和反应时间都表现不佳。非言语（而非言语）材料的情绪感知缺陷更为严重。在女性精神分裂症患者中，对愤怒的感知能力下降更为明显，而在男性精神分裂症患者中，对情绪语义的感知偏差更为明显。这些发现虽然初步，但表明了情绪感知的通道和类别特异性，以及精神分裂症患者之间可能存在性别差异，这具有重要的理论和实践意义。
