Several studies have suggested that schizophrenics have a deficit in their ability to recognize the affect expressed in photos of human faces. In this study, the performance of 17 chronic schizophrenics was compared to that of 17 controls on both a test of facial affect recognition and a control task involving facial recognition. Compared with controls, chronic schizophrenics tended to perform more poorly on the test of facial affect recognition, but this difference was eliminated when facial recognition was entered as a covariate. When all test items, including those with poor reliability and discriminatory power, were included in the analysis the schizophrenics showed a significant deficit in facial affect recognition which persisted even when facial recognition was used as a covariate.
多项研究表明，精神分裂症患者在识别人类面部照片所表达的情感方面存在能力缺陷。在本研究中，将17名慢性精神分裂症患者在面部情感识别测试和涉及面部识别的对照任务上的表现与17名对照组进行了比较。与对照组相比，慢性精神分裂症患者在面部情感识别测试中的表现往往较差，但当将面部识别作为协变量纳入时，这种差异就消除了。当分析中包括所有测试项目，包括那些可靠性和区分能力较差的项目时，精神分裂症患者在面部情感识别方面表现出显著缺陷，即使将面部识别用作协变量，这种缺陷仍然存在。
