精神分裂症与社会动机受损有关。社会注意力被认为是社会动机的一种潜在机制。然而，精神分裂症的研究很少研究社会注意力，这些研究都没有研究快速呈现刺激的影响。目前的研究探讨了精神分裂症患者是否减少了社会注意力，以及社会注意力的减少是否与社会动机缺陷（阴性症状临床评估访谈; CAINS）和社会功能下降（角色功能量表; RFS）有关。37名精神分裂症门诊患者和29名健康受试者在不同的刺激起始时间完成了定向社交线索（眼睛凝视）和非社交线索（箭头）的凝视提示任务。正如预测的那样，与健康的参与者相比，精神分裂症参与者的社会注意力相对于非社会注意力减少。健康的参与者对社会线索的反应比非社会线索更快，但精神分裂症参与者没有表现出相同的模式。当目标出现在与非社会性线索（而非社会性线索）相同的位置时，精神分裂症参与者表现出更高的准确性（即一致性）。与预期相反，精神分裂症组的社会注意力下降与临床评定的社会动机缺陷或社会功能下降无显著相关性。这些发现为精神分裂症患者的社会注意力缺陷提供了证据，但没有明确描绘其对社会动机的影响。
Schizophrenia is associated with impairments in social motivation. Social attention has been proposed as an underlying mechanism for social motivation. However, studies in schizophrenia have rarely examined social attention, and none of these studies examined the effects with rapidly presented stimuli. The current study examined whether individuals with schizophrenia have reduced social attention and whether reduced social attention was related to social motivation deficits (measured with the Clinical Assessment Interview for Negative Symptoms; CAINS) and decreased social functioning (Role Functioning Scale; RFS). Thirty-seven outpatients with schizophrenia and 29 healthy participants completed a gaze cueing task with directional social cues (eye gaze) and nonsocial cues (arrows) at varying stimulus onset asynchronies. As predicted, schizophrenia participants had reduced social attention relative to nonsocial attention, compared with healthy participants. Healthy participants were quicker to respond to social cues than nonsocial cues, but schizophrenia participants did not exhibit this same pattern. Schizophrenia participants showed higher accuracy when targets appeared in the same location as a directional cue (i.e. congruency) for nonsocial, but not social, cues. Contrary to expectations, reduced social attention was not significantly correlated with clinically rated social motivation deficits or decreased social functioning in the schizophrenia group. These findings provide evidence for social attention deficits in schizophrenia, but without a clear mapping of its influence on social motivation.
