Persons with schizophrenia experience deficits in social cognition-the cognitive processes involved in how people perceive and interpret information about themselves, others, and social situations. These deficits may be related to the neurocognitive impairments often experienced by persons with schizophrenia. Our primary objective was to examine associations between social perception and early visual processing in schizophrenia. Our secondary objective was to examine whether outpatients with schizophrenia and healthy persons differ in social perception. Forty outpatients with schizophrenia and 30 healthy persons completed a measure of social perception (the Half-Profile of Nonverbal Sensitivity), visual masking procedures, and ratings of positive and negative symptoms. Within patients, performance on visual masking procedures was related to performance on the Half-Profile of Nonverbal Sensitivity. Patients with schizophrenia and the healthy persons differed significantly in their performance on the Half-Profile of Nonverbal Sensitivity, but this difference became nonsignificant when education was a covariate. These findings suggest that social perception in schizophrenia is related to very early aspects of visual processing.
精神分裂症患者存在社会认知缺陷,即人们在感知和解释有关自身、他人及社会情境信息时所涉及的认知过程。这些缺陷可能与精神分裂症患者常经历的神经认知损害有关。我们的主要目标是研究精神分裂症患者的社会感知与早期视觉加工之间的关联。我们的次要目标是研究精神分裂症门诊患者与健康人在社会感知方面是否存在差异。40名精神分裂症门诊患者和30名健康人完成了一项社会感知测量(非言语敏感性半剖面图)、视觉掩蔽程序以及阳性和阴性症状评定。在患者内部,视觉掩蔽程序的表现与非言语敏感性半剖面图的表现相关。精神分裂症患者和健康人在非言语敏感性半剖面图上的表现存在显著差异,但当以教育程度作为协变量时,这种差异变得不显著。这些发现表明,精神分裂症患者的社会感知与视觉加工的非常早期阶段有关。
