目的：面部情感识别缺陷在精神分裂症患者中已经得到了很好的证实，但相对较少的研究考察了假想的精神病倾向或分裂型个体的面部情感识别。那些研究精神疾病易患个体的社会认知的研究很少注意到面部情绪识别和特定的分裂型人格特征之间的联系。因此，本研究试图调查面部情绪识别和分裂类型的不同方面之间的关系。方法：采用精神分裂人格问卷对50名精神健康受试者的面部表情识别准确率进行检测。该工具提供了精神分裂症倾向的多维测量，包括分裂类型的认知-知觉、人际关系和混乱特征。有人假设，分裂类型的认知-知觉和人际关系方面与使用标准化的一系列彩色照片在强制选择识别任务中识别面部情绪表达的困难有关。结果：正如预测的那样，分裂类型的人际关系方面(特别是社交焦虑)与面部情感识别任务的准确性降低有关，但情感识别的准确性与分裂类型的认知-知觉特征之间没有关联。结论：这些结果表明，在其他精神健康的个体中，面部情感识别的细微缺陷可能与人际沟通困难的脆弱性有关，如精神分裂症。
Aim: Deficits in facial affect recognition are well established in schizophrenia, yet relatively little research has examined facial affect recognition in hypothetically psychosis-prone or schizotypal individuals. Those studies that have examined social cognition in psychosis-prone individuals have paid little attention to the association between facial emotion recognition and particular schizotypal personality features. The present study therefore sought to investigate relationships between facial emotion recognition and the different aspects of schizotypy. Methods: Facial affect recognition accuracy was examined in 50 psychiatrically healthy individuals assessed for level of schizotypy using the Schizotypal Personality Questionnaire. This instrument provides a multidimensional measure of schizophrenia proneness, encompassing cognitive-perceptual, interpersonal and disorganized features of schizotypy. It was hypothesized that the cognitive-perceptual and interpersonal aspects of schizotypy would be associated with difficulties identifying facial expressions of emotion during a forced-choice recognition task using a standardized series of colour photographs. Results: As predicted, interpersonal aspects of schizotypy (particularly social anxiety) were associated with reduced accuracy on the facial affect recognition task, but there was no association between affect recognition accuracy and cognitive-perceptual features of schizotypy. Conclusions: These results suggest that subtle deficits in facial affect recognition in otherwise psychiatrically healthy individuals may be related to the vulnerability for interpersonal communication difficulties, as seen in schizophrenia.
