背景面部情绪识别（FIR）缺陷在精神分裂症中是有据可查的，并已被提出作为一个潜在的中间表型精神分裂症的易感性。然而，精神病脆弱性和FER之间的关系的研究有混合的结果和方法的局限性。此外，还没有研究表征PER能力和精神病倾向水平之间的关系。如果FER能力随精神病倾向而连续变化，这表明FER与多基因危险因素之间存在关系。我们测试了两个大的互联网样本，看看是否心理测量精神病倾向，作为衡量领带分裂型人格测验-简报（SPQ-B），是与面部情绪识别和歧视或其他面孔处理能力的差异。实验一（n = 2332）表明，精神病倾向性可以预测面孔情绪识别能力，但不能预测面孔性别识别能力。实验2（n = 1514）表明，精神病倾向也预测的面孔情绪，但没有面孔身份歧视的表现。实验2中的任务使用相同的刺激和任务参数，不同的只是在情绪/身份判断。值得注意的是，在实验1和2中证明的关系持续存在，即使个人与最高的精神病倾向水平（推定的高风险组）被排除在分析之外。我们的数据表明，FER能力与正常人群中精神病样特征的个体差异有关，并且这些差异不能通过面部处理和/或视觉感知的差异来解释。我们的研究结果表明，PER可能提供一个有用的候选中间表型。
Background. Deficits in face emotion recognition (FIR) in schizophrenia are well documented, and have been proposed as a potential intermediate phenotype for schizophrenia liability. However, research on the relationship between psychosis vulnerability and FER has mixed findings and methodological limitations. Moreover, no study has yet characterized the relationship between PER ability and level of psychosis-proneness. If FER ability varies continuously with psychosis-proneness, this suggests a relationship between FER and polygenic risk factors.Method. We tested two large internet samples to see whether psychometric psychosis-proneness, as measured by tie Schizotypal Personality Questionnaire-Brief (SPQ-B), is related to differences in face emotion identification and discrimination or other face processing abilities.Results. Experiment 1 (n = 2332) showed that psychosis-proneness predicts face emotion identification ability but not face gender identification ability. Experiment 2 (n = 1514) demonstrated that psychosis-proneness also predicts performance on face emotion but not face identity discrimination. The tasks in Experiment 2 used identical stimuli and task parameters, differing only in emotion/identity judgment. Notably, the relationships demonstrated in Experiments 1 and 2 persisted even when individuals with the highest psychosis-proneness levels (the putative high-risk group) were excluded from analysis.Conclusions. Our data suggest that FER ability is related to individual differences in psychosis-like characteristics in the normal population, and that these differences cannot be accounted for by differences in face processing and/or visual perception. Our results suggest that PER may provide a useful candidate intermediate phenotype.
