面部表情识别受损与重度抑郁症的特征有关。这可能是这些患者社交互动中出现一些困难的原因。重度抑郁症患者以及年龄和性别匹配的健康志愿者对 100 种面部刺激的情绪进行了判断，这些刺激表现出不同强度的悲伤和快乐以及短（100 毫秒）和长（2,000 毫秒）持续时间的中性表情。与健康志愿者相比。抑郁症患者在辨别准确性方面表现出轻微的障碍，并且对将轻微快乐的表情识别为快乐存在着显着的偏见。作者认为，抑郁症患者无法准确识别他人在社交场合所表现出的面部表情的细微变化，可能是人际功能受损的原因。
Impaired facial expression recognition has been associated with features of major depression. which could underlie some of the difficulties in social interactions in these patients. Patients with major depressive disorder and age- and gender-matched healthy volunteers judged the emotion of 100 facial stimuli displaying different intensities of sadness and happiness and neutral expressions presented for short (100 ms) and long (2,000 ms) durations. Compared with healthy volunteers. depressed patients demonstrated subtle impairments in discrimination accuracy and a predominant bias away from the identification as happy of mildly happy expressions. The authors suggest that, in depressed patients, the inability to accurately identify subtle changes in facial expression displayed by others in social situations may underlie the impaired interpersonal functioning.
