A number of studies have reported mood-congruent biases in processing facial expressions of emotion in depression and mania. Most of them have failed to establish that mood reliably affects relevant more than irrelevant expressions, or that the effect is specifically mood-related rather than due to resource or task difficulty artefacts. The aim was to examine, using appropriate statistical methods, whether depressed mood in bipolar patients decreases and manic mood increases sensitivity to facial expressions of happiness and vice versa for facial expressions of negative emotion.
Sensitivity to facial expression of six basic emotions in bipolar patients when depressed and when manic was compared to closely matched controls.
Mood-related biases in sensitivity to facial expressions of happiness and of negative affect in general operate in persons with bipolar disorder when depressed. There is little evidence of similar biases in persons with bipolar disorder when manic.
These data show a mood-congruent bias in sensitivity to facial expressions in bipolar depressed patients.
多项研究报告了在抑郁症和躁狂症患者处理情绪面部表情时存在情绪一致性偏差。其中大多数研究未能证实情绪对相关表情的影响比无关表情更可靠，或者这种影响是与情绪特异性相关，而非由于资源或任务难度假象。目的是使用适当的统计方法，研究双相情感障碍患者的抑郁情绪是否会降低、躁狂情绪是否会增加对快乐面部表情的敏感性，反之对于负面情绪的面部表情是否相反。
将双相情感障碍患者抑郁和躁狂时对六种基本情绪面部表情的敏感性与匹配良好的对照组进行比较。
双相情感障碍患者抑郁时，对快乐和一般负面情绪面部表情的敏感性存在与情绪相关的偏差。几乎没有证据表明双相情感障碍患者躁狂时存在类似偏差。
这些数据表明双相抑郁患者在对面部表情的敏感性上存在情绪一致性偏差。
