NRR:认知重评可对负性情绪调节发挥作用

　　认知重评可以通过作用于情绪刺激的早期加工，来对情绪事件的意义发挥作用。《中国神经再生研究（英文版）》杂志于2012年11月32期出版的一项关于Neural bases of reappraisal regulatory effect on negative emotion in high reappraisers的研究，将善于重评的被试者进入功能MRI实验，并进行2次重评训练，结果显示认知重评显著降低了参与者的负性情绪唤醒水平，同时功能性核磁共振结果表明，在认知重评条件下，那些善于使用重评调节负性情绪的参与者表现出情绪反应区的脑激活下降，包括杏仁核、脑岛、背部扣带回等，而与情绪调节密切相关的下部额叶、眶部额叶和背内侧额叶等脑区表现出显著的激活增强。表明擅长参与重评者下眶部额叶和背内侧额叶可参与负性情绪的认知重评调节。

Neural bases of reappraisal regulatory effect on negative emotion in high reappraisers

Abstract  

Previous studies have reported that individual differences in reappraisal use are associated with particular patterns of neural activity. We hypothesized that if ‘high reappraisers’ (individuals who use reappraisal well in a behavioral experiment) completed two training sessions, they would exhibit more reliable patterns of neural activity related to cognitive reappraisal. In the present study, 13 high reappraisers were selected from 27 healthy volunteers through an initial behavioral experiment (first training) followed by a functional MRI experiment (second training). Emotional images selected from the International Affective Picture System were used for both the behavioral and functional MRI sessions of the experiment. The behavioral results revealed that reappraisal reduced subjective unpleasantness. The functional MRI results revealed that the cognitive reappraisal used by high reappraisers decreased the activation of emotion-responsive regions, including the amygdala, insula, and cingulate gyrus, and increased the activation of regulation-related regions, including the inferior prefrontal cortex, orbital prefrontal cortex, and dorsal medial prefrontal cortex. These findings suggest the involvement of inferior orbital and dorsal medial prefrontal cortex in constructing reappraisal strategies that modulate activity in emotion-processing systems.
