冲突适应是一种认知机制，表现为在发现冲突时增强认知控制。这种机制可以通过一致性序列效应来衡量，表明在不一致试验（发生反应冲突）后，一致性效应相对于在一致试验（没有反应冲突）后减少。几项研究表明，与积极情绪相比，消极情绪会增加冲突适应。在这些研究中，持续的情绪状态是由结合想象技巧的电影片段或音乐引起的；这些情绪操纵是非常明显的，可能会扭曲参与者的实际情绪状态。在这里，我们报告了两个实验，其中情绪状态以一种不太明显的方式诱导，但具有更高的生态效度。参与者在一个虚假的智力测试中得到了成功或失败的反馈，这种情绪操纵被证明是非常有效的。在Flanker干扰范式（实验1）和stroop样干扰范式（实验2）中，我们在很大程度上重复了以往的研究结果，即消极情绪下的冲突适应大于积极情绪下的冲突适应。结果讨论了目前的理论对认知控制的情感影响。
Conflict adaptation is a cognitive mechanism denoting increased cognitive control upon detection of conflict. This mechanism can be measured by the congruency sequence effect, indicating the reduction of congruency effects after incongruent trials (where response conflict occurs) relative to congruent trials (without response conflict). Several studies have reported increased conflict adaptation under negative, as compared to positive, mood. In these studies, sustained mood states were induced by film clips or music combined with imagination techniques; these kinds of mood manipulations are highly obvious, possibly distorting the actual mood states experienced by the participants. Here, we report two experiments where mood states were induced in a less obvious way, and with higher ecological validity. Participants received success or failure feedback on their performance in a bogus intelligence test, and this mood manipulation proved highly effective. We largely replicated previous findings of larger conflict adaptation under negative mood than under positive mood, both with a Flanker interference paradigm (Experiment 1) and a Stroop-like interference paradigm (Experiment 2). Results are discussed with respect to current theories on affective influences on cognitive control.
