While it is known that patients with schizophrenia recognize facial emotions, specifically negative emotions, less accurately, little is known about how they misattribute these emotions to other emotions and whether such misattribution biases are associated with symptoms, course of the disorder, or certain cognitive functions.
Outpatients with schizophrenia or schizoaffective disorder (n=73) and healthy controls (n=30) performed a computerised Facial Emotion Attribution Test and Wisconsin Card Sorting Test (WCST). Patients were also rated on the Positive and Negative Syndrome Scale (PANSS).
Patients were poor at recognizing fearful and angry emotions and attributed fear to angry and angry to neutral expressions. Fear-as-anger misattributions were predicted independently by a longer duration of illness and WCST perseverative errors.
The findings show a bias towards misattributing fearful and angry facial emotions. The propensity for fear-as-anger misattribution biases increases as the length of time that the disorder is experienced increases and a more rigid style of information processing is used. This, at least in part, may be perpetuated by subtle fearfulness expressed by others while interacting with people with schizophrenia.
虽然已知精神分裂症患者识别面部情绪，尤其是负面情绪的准确性较低，但对于他们如何将这些情绪错误归因于其他情绪，以及这种错误归因偏差是否与症状、疾病进程或某些认知功能相关，却知之甚少。
对患有精神分裂症或分裂情感性障碍的门诊患者（n = 73）和健康对照者（n = 30）进行了计算机化面部情绪归因测试和威斯康星卡片分类测试（WCST）。还使用阳性和阴性症状量表（PANSS）对患者进行了评分。
患者在识别恐惧和愤怒情绪方面表现较差，将恐惧归因于愤怒，将愤怒归因于中性表情。恐惧误归为愤怒的情况由病程较长和WCST持续性错误独立预测。
研究结果显示出对面部恐惧和愤怒情绪的错误归因倾向。随着患病时间的延长以及采用更僵化的信息处理方式，恐惧误归为愤怒的归因偏差倾向会增加。这至少部分可能是由于与精神分裂症患者互动时他人表现出的微妙恐惧情绪而持续存在。
