Facial emotion recognition deficits have been widely investigated in individuals with schizophrenia; however, it remains unclear whether these deficits reflect a trait-like vulnerability to schizophrenia pathology present in individuals at risk for the disorder. Although some studies have investigated emotion recognition in this population, findings have been mixed. The current study uses a well-validated emotion recognition task, a relatively large sample, and examines the relationship between emotion recognition, symptoms, and overall life quality. Eighty-nine individuals with psychometrically defined schizotypy and 27 controls completed the Schizotypal Personality Questionnaire, Penn Emotion Recognition Test, and a brief version of Lehman's Quality of Life Interview. In addition to labeling facial emotions, participants rated the valence of faces using a Likert rating scale. Individuals with schizotypy were significantly less accurate than controls when labeling emotional faces, particularly neutral faces. Within the schizotypy sample, both disorganization symptoms and lower quality of life were associated with a bias toward perceiving facial expressions as more negative. Our results support previous research suggesting that poor emotion recognition is associated with vulnerability to psychosis. Although emotion recognition appears unrelated to symptoms, it probably operates by means of different processes in those with particular types of symptoms.
面部情绪识别缺陷在精神分裂症患者中得到了广泛研究；然而，目前尚不清楚这些缺陷是否反映了处于精神分裂症病理风险中的个体的一种特质性易感性。尽管一些研究已经调查了这一人群的情绪识别能力，但研究结果却存在差异。本研究使用了一种经过良好验证的情绪识别任务、相对较大的样本，并考察了情绪识别、症状和整体生活质量之间的关系。89 名具有心理定义的精神分裂症倾向的个体和 27 名对照者完成了精神分裂症人格问卷、宾夕法尼亚情绪识别测试和莱曼生活质量访谈的简短版本。除了标记面部表情外，参与者还使用李克特量表来评价面孔的效价。在标记情绪面孔时，精神分裂症倾向个体的准确性明显低于对照组，尤其是在标记中性面孔时。在精神分裂症倾向样本中，组织障碍症状和较低的生活质量与感知面部表情更负面的偏见有关。我们的结果支持了先前的研究，即较差的情绪识别与精神病易感性有关。尽管情绪识别似乎与症状无关，但它可能通过具有特定类型症状的个体的不同过程起作用。
