Previous studies have provided some evidence of the neural basis of the emotional conflict adaptation effect. However, the neural time-course is largely unknown. Therefore, a face-word Stroop task was used in the present study to explore the neural dynamics of the emotional conflict control effect, using event-related potentials (ERPs). The behavioral data showed a robust emotional conflict adaptation effect, and there was an interaction between previous trials and current trials for RT. There were two ERP components (N450 and conflict SP) that might be related to trial congruency. The N450 results showed both a main effect of current trial congruency and an interaction between previous trials and current trials, which might be related to successful conflict adaptation. The SP results only showed the main effect of current trial congruency, which might be associated with post-response monitoring.
以往的研究已经提供了一些关于情绪冲突适应效应神经基础的证据。然而，神经时间进程在很大程度上仍不清楚。因此，在本研究中使用了一个面孔-单词Stroop任务，通过事件相关电位（ERP）来探究情绪冲突控制效应的神经动力学。行为数据显示出强大的情绪冲突适应效应，并且反应时在前次试验和当前试验之间存在交互作用。有两个ERP成分（N450和冲突相关的SP）可能与试验一致性有关。N450的结果显示出当前试验一致性的主效应以及前次试验和当前试验之间的交互作用，这可能与成功的冲突适应有关。SP的结果仅显示了当前试验一致性的主效应，这可能与反应后监测有关。
