Frontal EEG activity is thought to reflect affective dispositions, but may also reflect the emotional demands of a specific context combined with the capability to regulate emotions in that context. The present study examined this hypothesis by testing whether frontal EEG activity during mood inductions versus a resting baseline predicted emotion regulation. EEG was recorded while participants (N=66, 40 females) received a fearful, sad, or neutral mood induction. Emotion regulation was measured following the mood inductions as self-reported change in negative mood and as attention interference in a task with mood-congruent emotional distracters. Greater frontal EEG activity during the mood inductions versus baseline was associated with more effective emotion regulation: less post-induction sadness and anxiety and reduced mood-congruent attention interference effects. Effects did not differ between the left and right hemispheres. Results support the hypothesis that frontal EEG activity reflects both emotional context and emotion-regulatory capabilities.
额EEG 活动被认为反映了情感倾向,但也可能反映了特定情境下的情绪需求,以及在该情境下调节情绪的能力。本研究通过测试情绪诱导期间与静息基线相比的额 EEG 活动是否预测情绪调节,检验了这一假设。在参与者(N=66,40 名女性)接受恐惧、悲伤或中性情绪诱导的同时记录 EEG。在情绪诱导后,通过自我报告的负面情绪变化和在具有情绪一致情绪干扰物的任务中的注意力干扰来测量情绪调节。与基线相比,情绪诱导期间的额 EEG 活动越大,情绪调节越有效:诱导后悲伤和焦虑减少,与情绪一致的注意力干扰效应降低。左右半球之间的效果没有差异。结果支持这样一种假设,即额 EEG 活动反映了情绪背景和情绪调节能力。
