Cognitive reappraisal is a commonly used and highly adaptive strategy for emotion regulation that has been studied in healthy volunteers. Most studies to date have focused on forms of reappraisal that involve reinterpreting the meaning of stimuli and have intermixed social and non-social emotional stimuli. Here we examined the neural correlates of the regulation of negative emotion elicited by social situations using a less studied form of reappraisal known as distancing. Whole brain fMRI data were obtained as participants viewed aversive and neutral social scenes with instructions to either simply look at and respond naturally to the images or to downregulate their emotional responses by distancing. Three key findings were obtained accompanied with the reduced aversive response behaviorally. First, across both instruction types, aversive social images activated the amygdala. Second, across both image types, distancing activated the precuneus and posterior cingulate cortex (PCC), intraparietal sulci (IPS), and middle/superior temporal gyrus (M/STG). Third, when distancing one's self from aversive images, activity increased in dorsal anterior cingulate (dACC), medial prefrontal cortex (mPFC), lateral prefrontal cortex, precuneus and PCC, IPS, and M/STG, meanwhile, and decreased in the amygdala. These findings demonstrate that distancing from aversive social cues modulates amygdala activity via engagement of networks implicated in social perception, perspective-taking, and attentional allocation.
认知重评是一种常用于情绪调节的高度适应性策略,已在健康志愿者中进行了研究。迄今为止,大多数研究都集中在重新解释刺激意义的重评形式上,并混合了社会和非社会情感刺激。在这里,我们使用一种称为距离的研究较少的重评形式来检查调节社会情境引起的负面情绪的神经相关性。当参与者观看带有指令的厌恶和中性社交场景时,会获得全脑 fMRI 数据,这些指令要么只是观察并自然地对图像做出反应,要么通过距离来抑制他们的情绪反应。在行为上减少厌恶反应的同时,获得了三个关键发现。首先,在两种指令类型中,厌恶的社交图像都会激活杏仁核。其次,在两种图像类型中,距离都会激活顶内沟(IPS)和中/上颞叶(M/STG)。第三,当人们将自己与厌恶的图像拉开距离时,背侧前扣带(dACC)、内侧前额叶皮层(mPFC)、外侧前额叶皮层、顶内沟和后扣带皮层(PCC)、IPS 和 M/STG 的活动增加,而杏仁核的活动减少。这些发现表明,通过参与涉及社会感知、换位思考和注意力分配的网络,从厌恶的社交线索中拉开距离可以调节杏仁核的活动。
