Some studies have reported deficits in the perception of facial expressions among depressed individuals compared with healthy controls, while others have reported negative biases in expression perception. We examined whether altered perception of emotion reflects an underlying trait-like effect in affective disorder by examining facial expression perception in euthymic bipolar patients.
Sensitivity to six different facial expressions, as well as accuracy of emotion recognition, was examined among 17 euthymic bipolar patients and 17 healthy controls using an interactive computer program.
No differences were found between euthymic bipolar patients and controls in terms of sensitivity to any particular emotion. Although initial analysis of the data suggested impairment in the recognition of fear among the patients, identification of this emotion was not relatively impaired compared with that of the other emotions.
The study did not find any conclusive evidence for trait-like deficits in the perception of facially conveyed emotions in bipolar disorder. Altered perception of facial expressions that has been found to accompany depressed mood may instead reflect mood-congruent biases.
一些研究报告称，与健康对照组相比，抑郁症患者在面部表情感知方面存在缺陷，而另一些研究则报告了表情感知中的负性偏差。我们通过检查心境正常的双相情感障碍患者的面部表情感知，来探究情绪感知的改变是否反映了情感障碍中一种潜在的特质样效应。
使用一个交互式计算机程序，对17名心境正常的双相情感障碍患者和17名健康对照者进行了六种不同面部表情的敏感性以及情绪识别准确性的检测。
心境正常的双相情感障碍患者与对照组在对任何特定情绪的敏感性方面均未发现差异。尽管对数据的初步分析表明患者在恐惧识别方面存在障碍，但与其他情绪相比，这种情绪的识别并没有相对受损。
该研究未发现双相情感障碍患者在对面部传达的情绪感知方面存在特质样缺陷的确凿证据。已发现伴随抑郁情绪出现的面部表情感知改变可能反而反映了心境一致的偏差。
