目的：作者使用情绪和中性表情的彩色照片来研究精神分裂症患者对五种普遍情绪的识别模式。方法：28例稳定期门诊精神分裂症患者（19名男性和9名女性）和61名健康受试者（29名男性和32名女性）完成了一项情绪辨别测试，该测试呈现了轻度和极端强度的快乐，悲伤，愤怒，恐惧，厌恶和中性面孔，性别和种族平衡。分析评估的准确性识别情绪的强度，诊断，和性别的poser和rater.Results的功能：患者表现不如比较科目的所有情绪和中性面孔相结合，包括温和和极端的表情识别。对于特定的情绪，患者在识别恐惧，厌恶和中性表情方面表现较差。对于除厌恶外的所有情绪，极端强度的识别优于轻度强度的识别。然而，患者从所有情绪组合的强度增加中获益较少，差异最明显的是恐惧。因此，患者在识别高强度表达方面比健康对照受试者受损更严重，即使这比识别低强度表达更容易。在错误模式的比较中，患者和健康受试者不同，只有在错误归因的中性表情;患者过度归因于厌恶的表情和归因不足的快乐expressions.Conclusions：精神分裂症患者受损的整体情绪识别，特别是恐惧和厌恶，并没有受益于情绪强度的增加。错误模式表明，患者误认为中性线索为负效价。
Objective: The authors used color photographs of emotional and neutral expressions to investigate recognition patterns of five universal emotions in schizophrenia.Method: Twenty-eight stable outpatients with schizophrenia (19 men and nine women) and 61 healthy subjects (29 men and 32 women) completed an emotion discrimination test that presented mild and extreme intensities of happy, sad, angry, fearful, disgusted, and neutral faces, balanced for gender and ethnicity. Analyses evaluated accuracy of identifying emotions as a function of intensity, diagnosis, and gender of poser and rater.Results: Patients performed worse than comparison subjects on recognition of all emotions and neutral faces combined, including mild and extreme expressions. For specific emotions, patients performed worse on recognition of fearful, disgusted, and neutral expressions. For all emotions except disgust, recognition of extreme intensity was better than recognition of mild intensity. However, patients showed less benefit from increased intensity for all emotions combined, and the difference was most pronounced for fear. Thus, patients were more impaired than healthy comparison subjects in identifying high-intensity expressions, even though this was an easier task than identifying low-intensity expressions. In the comparison of patterns of errors, patients and healthy subjects differed only in misattributions of neutral expressions; patients overattributed disgusted expressions and underattributed happy expressions.Conclusions: Patients with schizophrenia were impaired in overall emotion recognition, particularly fear and disgust, and did not benefit from increased emotional intensity. Error patterns indicate that patients misidentified neutral cues as negatively valenced.
