Abstract

Distraction and reappraisal are two commonly used forms of cognitive emotion regulation. Functional neuroimaging studies have shown that each one depends upon interactions between pFC, interpreted as implementing cognitive control, and limbic regions, interpreted as mediating emotional responses. However, no study has directly compared distraction with reappraisal, and it remains unclear whether they draw upon different neural mechanisms and have different emotional consequences. The present fMRI study compared distraction and reappraisal and found both similarities and differences between the two forms of emotion regulation. Both resulted in decreased negative affect, decreased activation in the amygdala, and increased activation in prefrontal and cingulate regions. Relative to distraction, reappraisal led to greater decreases in negative affect and to greater increases in a network of regions associated with processing affective meaning (medial prefrontal and anterior temporal cortices). Relative to reappraisal, distraction led to greater decreases in amygdala activation and to greater increases in activation in prefrontal and parietal regions. Taken together, these data suggest that distraction and reappraisal differentially engage neural systems involved in attentional deployment and cognitive reframing and have different emotional consequences.

摘要

分心和重评是两种常用的认知情绪调节形式。功能神经影像学研究表明,每一种形式都依赖于前额叶皮层(pFC)和边缘区域之间的相互作用,前者被解释为执行认知控制,后者被解释为介导情绪反应。然而,没有研究直接比较分心和重评,也不清楚它们是否依赖于不同的神经机制,以及是否具有不同的情绪后果。本 fMRI 研究比较了分心和重评,发现这两种情绪调节形式既有相似之处,也有不同之处。两者都导致负面情绪减少,杏仁核激活减少,前额叶和扣带回区域激活增加。与分心相比,重评导致负面情绪减少更多,与处理情感意义相关的区域(内侧前额叶和前颞叶皮质)的激活增加更多。与重评相比,分心导致杏仁核激活减少更多,前额叶和顶叶区域的激活增加更多。综上所述,这些数据表明,分心和重评以不同的方式利用参与注意力部署和认知重构的神经系统,并且具有不同的情绪后果。
