Individuals with schizophrenia have difficulties in recognizing facial emotions in others. This study investigated whether this impairment also exists for self-generated expressions. Nineteen patients with schizophrenia and 19 comparison subjects were filmed while producing facial expressions in response to a visual model or a written sentence. After 2 months, all subjects were asked to rate their own emotional expressions. These ratings were compared with the evaluations of 12 healthy independent raters. With respect to the comparison subjects, the patients produced less expressive responses and were less able to recognize their own expressions. Moreover, patients were totally unaware of these impairments.
精神分裂症患者在识别他人的面部情绪时存在困难。本研究旨在探究这种障碍是否也存在于自我生成的表情中。19 名精神分裂症患者和 19 名对照组被拍摄，他们在观看视觉模型或阅读书面句子后，做出面部表情。2 个月后，所有参与者被要求对自己的情绪表达进行评分。这些评分与 12 名健康独立评分者的评估进行了比较。与对照组相比，患者的表情反应较少，识别自己表情的能力也较差。此外，患者对这些缺陷完全没有意识。
