Schizophrenia patients have demonstrated deficits in affect recognition. Whether this deficit is part of a general difficulty in face perception or a specific problem in affect recognition is debatable. However, there is little research investigating the functional consequences of difficulties in identifying emotion in schizophrenia patients. We tested 20 chronic, medicated schizophrenia patients and 27 normal control participants on a battery of face recognition and affect recognition tasks. A subset of 14 patients was rated on the Social Dysfunction Index. Results demonstrated that schizophrenia patients were less accurate than normal control participants on face recognition, facial affect recognition and vocal affect recognition tasks, but among schizophrenia patients, only affect recognition performance was related to social functioning. These results suggest that schizophrenia patients have general face processing deficits, but affect recognition deficits may lead to more problems in social behavior.
精神分裂症患者在情感识别方面存在缺陷。这种缺陷是面部感知普遍困难的一部分，还是情感识别方面的特定问题，尚无定论。然而，很少有研究调查精神分裂症患者在识别情绪方面存在困难所产生的功能后果。我们对20名慢性服药的精神分裂症患者和27名正常对照参与者进行了一系列面部识别和情感识别任务测试。对其中14名患者进行了社会功能障碍指数评分。结果表明，精神分裂症患者在面部识别、面部情感识别和声音情感识别任务上的准确性低于正常对照参与者，但在精神分裂症患者中，只有情感识别表现与社会功能有关。这些结果表明，精神分裂症患者存在一般的面部处理缺陷，但情感识别缺陷可能会在社会行为中导致更多问题。
