We examined event-related brain potential (ERP) modulations during the anticipation and processing of unpleasant pictures under instructions to cognitively decrease and increase negative emotion. Instructions to decrease and increase negative emotion modulated the ERP response to unpleasant pictures in the direction of emotional intensity beginning around 400 ms and lasting several seconds. Decrease, but not increase, instructions also elicited enhanced frontal negativity associated with orienting and preparation prior to unpleasant picture onset. Last, ERP modulation by unpleasant pictures began around 300 ms, just prior to regulation effects, suggesting that appraisal of emotion occurs before emotion regulation. Together, the current findings underscore the utility of ERPs in illuminating the time course of emotion modulation and regulation that may help to refine extant theoretical models.
我们研究了在认知上减少和增加负面情绪的指令下，对不愉快图片进行预期和处理期间的事件相关脑电位（ERP）调制。减少和增加负面情绪的指令在大约400毫秒开始并持续数秒的时间内，朝着情绪强度的方向调制了对不愉快图片的ERP反应。减少（而非增加）负面情绪的指令还引发了与不愉快图片出现之前的定向和准备相关的额叶负波增强。最后，不愉快图片引起的ERP调制在大约300毫秒开始，就在调节效应之前，这表明情绪评估发生在情绪调节之前。总之，当前的研究结果强调了ERP在阐明情绪调制和调节的时间进程方面的作用，这可能有助于完善现有的理论模型。
