以往的研究表明，精神分裂症患者在面部信息处理方面存在缺陷。本研究旨在探讨精神分裂症患者和正常对照者在情绪和身份匹配两个维度正交变化时的匹配能力。受试者（20名精神分裂症患者和20名对照组）必须报告两张面孔是否具有相同的情绪或属于同一个人。当任务涉及一种类型的信息（即情绪或身份）时，另一种信息要么是恒定的（同一个人或同一种情绪），要么是变化的（不同的人或不同的情绪）。精神分裂症患者在这两种面部信息上的表现都比对照组差。当次要因素改变时，他们的赤字更重要。特别是，当他们必须匹配两个不同的人表达的一种情绪时，他们的表现处于偶然水平。最后，相关性分析表明，性能/赤字的身份和情感匹配共变，在这样的任务中的性能与患者的阴性症状的严重程度呈负相关。精神分裂症患者在获取面部信息方面存在普遍缺陷。面部情绪和身份处理缺陷与阴性症状有关。人脸识别模型的影响进行了讨论。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
Previous studies showed that schizophrenic patients have a deficit in facial information processing. The purpose of the present study was to test the abilities of patients with schizophrenia and normal controls in emotion and identity matching when these two dimensions were varied orthogonally. Subjects (20 schizophrenic patients and 20 controls) had to report if two faces had the same emotion or belonged to the same person. When the task concerned one type of information (i.e. emotion or identity), the other one was either constant (same person or same emotion) or changed (different person or different emotion). Schizophrenic patients performed worse than controls for both kinds of facial information. Their deficit was more important when the secondary factor was changed. In particular, they performed at chance level when they had to match one emotion expressed by two distinct persons. Finally, correlation analysis indicated that performance/deficit in identity and emotion matching co-varied and that in such tasks performance is negatively correlated with the severity of negative symptoms in patients. Schizophrenic patients present a generalised deficit for accessing facial information. A facial emotion and an identity processing deficit are related to negative symptoms. Implications for face-recognition models are discussed. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
