对抑郁症患者的知觉和注意过程的研究表明，抑郁症患者与非抑郁症患者相比，在多刺激表征中不会表现出积极的知觉偏差。本研究采用人群中的面孔任务考察了抑郁与正面和负面情绪面部表情空间检测的关系。30名受试者（15名临床稳定的抑郁症住院患者和15名正常受试者）使用示意性面孔显示器进行了人群中的面孔任务。与正常受试者相比，抑郁症受试者在检测负鞋带方面没有表现差异，在控制条件（所有中性面孔）下的决策延迟也没有差异。然而，抑郁的受试者对积极面孔的反应明显慢于正常受试者。我们的数据表明，抑郁情绪与积极面部表情的空间注意力降低有关，而与消极面部表情的异常空间处理无关。这意味着，降低警惕的喜悦和幸福的面部表情可能会影响抑郁症患者的人际关系。
Research on perceptual and attentional processes in depression has shown that depressed as opposed to nondepressed individuals do not exhibit a positive perceptual bias in multistimulus representations. In the present study a face-in-the-crowd task was applied to examine the relationship between depression and spatial detection of facial expression of positive and negative emotions. A face-in-the-crowd task was administered to 30 subjects (15 clinically stabilized depressed inpatients and 15 normal subjects) using displays of schematic faces. Depressed subjects showed no performance differences in the detection of negative laces and no differences in decision latency for the control condition (all neutral faces) compared to normal subjects. Depressed subjects, however, were significantly slower in responding to positive faces than normal subjects. Our data suggest that depressive mood is associated with a reduced spatial attention to positive facial expression and not with an abnormal spatial processing of negative facial expression. An implication is that lowered vigilance for facial expressions of joy and happiness may affect adversely interpersonal relationships in depressed subjects.
