Since the introduction of the associative network theory, mood-congruent biases in emotional information processing have been established in individuals in a sad and happy mood. Research has concentrated on memory and attentional biases. According to the network theory, mood-congruent behavioral tendencies would also be predicted. Alternatively, a general avoidance pattern would also be in line with the theory. Since cognitive biases have been assumed to operate strongly in case of social stimuli, mood-induced biases in approach and avoidance behavior towards emotional facial expressions were studied. 306 females were subjected to a highly emotional fragment of a sad or a happy movie, to induce either a sad mood or a happy mood. An Approach-Avoidance Task was implemented, in which single pictures of faces (with angry, sad, happy, or neutral expression) and non-social control pictures were presented. In contrast to our expectations, mood states did not produce differential behavioral biases. Mood-congruent and mood-incongruent behavioral tendencies were, however, present in a subgroup of participants with highest depressive symptomatology scores. This suggests that behavioral approach-avoidance biases are not sensitive to mood state, but more related to depressive characteristics.
自从联想网络理论提出以来，处于悲伤和快乐情绪状态的个体在情绪信息处理中出现了情绪一致性偏差。研究主要集中在记忆和注意力偏差方面。根据该网络理论，情绪一致性行为倾向也应得到预测。另外，一种普遍的回避模式也与该理论相符。由于认知偏差被认为在面对社会刺激时会强烈起作用，因此研究了情绪诱发的对情绪化面部表情的趋近和回避行为偏差。306名女性观看了悲伤或快乐电影中高度情绪化的片段，以分别诱发悲伤情绪或快乐情绪。实施了一项趋近-回避任务，其中呈现了面部的单张图片（带有愤怒、悲伤、快乐或中性表情）以及非社会控制图片。与我们的预期相反，情绪状态并未产生不同的行为偏差。然而，在抑郁症状得分最高的参与者子群体中存在情绪一致性和情绪不一致性的行为倾向。这表明行为趋近-回避偏差对情绪状态不敏感，而更多地与抑郁特征相关。
