Emotion regulation strategies are thought to differ in when and how they influence the emotion-generative process. However, no study to date has directly probed the neural bases of two contrasting (e.g., cognitive versus behavioral) emotion regulation strategies. This study used functional magnetic resonance imaging (fMRI) to examine cognitive reappraisal (a cognitive strategy thought to have its impact early in the emotion-generative process) and expressive suppression (a behavioral strategy thought to have its impact later in the emotion-generative process).
Seventeen women viewed 15 sec neutral and negative emotion-eliciting films under four conditions--watch-neutral, watch-negative, reappraise-negative, and suppress-negative--while providing emotion experience ratings and having their facial expressions videotaped.
Reappraisal resulted in early (0-4.5 sec) prefrontal cortex (PFC) responses, decreased negative emotion experience, and decreased amygdala and insular responses. Suppression produced late (10.5-15 sec) PFC responses, decreased negative emotion behavior and experience, but increased amygdala and insular responses.
These findings demonstrate the differential efficacy of reappraisal and suppression on emotional experience, facial behavior, and neural response and highlight intriguing differences in the temporal dynamics of these two emotion regulation strategies.
情绪调节策略被认为在影响情绪产生过程的时间和方式上存在差异。然而,迄今为止尚无研究直接探究两种截然不同(例如,认知与行为)的情绪调节策略的神经基础。本研究使用功能磁共振成像(fMRI)来检验认知重评(一种被认为在情绪产生过程早期发挥作用的认知策略)和表达抑制(一种被认为在情绪产生过程后期发挥作用的行为策略)。
17名女性在四种条件下观看15秒的中性和负面情绪诱发影片——观看中性、观看负面、重评负面和抑制负面——同时提供情绪体验评分并录制她们的面部表情。
重评导致早期(0 - 4.5秒)前额叶皮层(PFC)反应,负面情绪体验减少,杏仁核和脑岛反应减弱。抑制产生晚期(10.5 - 15秒)PFC反应,负面情绪行为和体验减少,但杏仁核和脑岛反应增强。
这些发现证明了重评和抑制在情绪体验、面部行为和神经反应方面的不同效果,并突出了这两种情绪调节策略在时间动态上的有趣差异。
