The goal was to investigate whether patients with depression perform more poorly in overall emotion perception tasks compared with controls and whether this difference varies as a function of emotional intensity and arousal, with a perceptual bias toward high arousal emotions. Data were collected from 23 depressed and 23 control subjects, matched for gender, age, and education. Basic emotions were presented at 5 intensity levels ranging from 20% to 100%. Results showed that, relative to controls, patients with depression showed a significant impairment in the ability to recognize facial expressions, and that the impairment was most pronounced at subtle, but clearly recognizable emotional facial stimuli representing low arousal. Furthermore, depressed patients were found to make more misattribution errors of neutral and low arousal facial expressions in the direction of high arousal emotions. We conclude that the inability to accurately recognize nonemotional and emotional facial expressions along with the tendency for more attributions to the high arousal emotions can represent 2 basic contributing factors to the well-documented social problems of patients with depression.
本研究旨在调查与对照组相比，抑郁症患者在整体情绪感知任务中的表现是否更差，以及这种差异是否会随着情绪强度和唤醒水平的变化而变化，是否存在对高唤醒情绪的感知偏差。研究收集了23名抑郁症患者和23名对照者的数据，这些对照者在性别、年龄和教育程度上与患者相匹配。基本情绪以5种强度水平呈现，范围从20%到100%。结果显示，与对照组相比，抑郁症患者在识别面部表情的能力上存在显著损害，且这种损害在代表低唤醒的微妙但清晰可辨的情绪面部刺激中最为明显。此外，研究发现抑郁症患者在将中性和低唤醒面部表情错误归因于高唤醒情绪的方向上出现更多错误。我们得出结论，无法准确识别非情绪和情绪面部表情以及更多地将其归因于高唤醒情绪的倾向，可能是抑郁症患者社会问题的两个基本促成因素，这些问题已有充分记录。
