It is known that individuals with schizophrenia exhibit signs of impaired face processing, however, the exact perceptual and cognitive mechanisms underlying these deficits are yet to be elucidated. One possible source of confusion in the current literature is the methodological and conceptual inconsistencies that can arise from the varied treatment of different aspects of face processing relating to emotional and non-emotional aspects of face perception. This review aims to disentangle the literature by focusing on the performance of patients with schizophrenia in a range of tasks that required processing of non-emotional features of face stimuli (e.g., identity or gender). We also consider the performance of patients on non-face stimuli that share common elements such as familiarity (e.g., cars) and social relevance (e.g., gait). We conclude by exploring whether observed deficits are best considered as "face-specific" and note that further investigation is required to properly assess the potential contribution of more generalized attentional or perceptual impairments.
已知精神分裂症患者表现出面部处理受损的迹象，但这些缺陷的确切感知和认知机制尚未阐明。当前文献中的一个可能混淆来源是，由于对面部感知的情感和非情感方面的不同方面的处理方法和概念不一致，可能会出现方法学上的不一致。本综述旨在通过关注精神分裂症患者在一系列需要处理面部刺激的非情感特征（例如身份或性别）的任务中的表现来理清文献。我们还考虑了患者在具有共同特征（例如熟悉度（例如汽车）和社会相关性（例如步态）的非面部刺激上的表现。最后，我们探讨了观察到的缺陷是否最好被视为“特定于面部”，并指出需要进一步研究以正确评估更广泛的注意力或感知障碍的潜在贡献。
