Emotion recognition impairments have been demonstrated in schizophrenia, but few studies have examined whether these reflect generalised or specific perceptual deficits or are associated with illness course.
To examine the nature of emotion recognition abnormalities in patients with schizophrenia at different stages of illness.
We examined the performance of 50 in-patients with early-stage schizophrenia, 50 with chronic schizophrenia and 50 healthy controls on the Benton Facial Recognition Test, Facial Emotion Recognition Test and Voice Emotion Recognition Test.
Patients with chronic schizophrenia were significantly more impaired than other groups on the emotional tasks, even after controlling for impairments in non-emotional stimuli. Individual emotion recognition accuracy for the two sensory modalities was not significantly positively correlated for either group with schizophrenia.
Emotion recognition deficits in schizophrenia are trait features of the disorder and increase with illness duration.
精神分裂症患者已被证实存在情绪识别障碍，但很少有研究探讨这些障碍是反映了一般性还是特定的感知缺陷，或者是否与病程相关。
研究处于疾病不同阶段的精神分裂症患者情绪识别异常的本质。
我们对50例早期精神分裂症住院患者、50例慢性精神分裂症患者和50名健康对照者进行了本顿面部识别测试、面部情绪识别测试和语音情绪识别测试。
即使在控制了非情绪刺激的损伤后，慢性精神分裂症患者在情绪任务上的损伤仍显著高于其他组。精神分裂症两组患者在两种感觉模式下的个体情绪识别准确率均无显著正相关。
精神分裂症患者的情绪识别缺陷是该疾病的特质性特征，并随病程延长而增加。
