Although numerous studies have investigated emotion regulation, the physiological responses and neural substrates of positive emotion regulation remain unclear. To address this question, we explored the effect of reappraisal on subjective experience, zygomatic electromyography (zEMG) response, and blood oxygen level response, using the same materials across three independent experiments. Behaviorally, up-regulating positive emotion increased the valence, arousal, and zEMG response, whereas down-regulating positive emotion decreased the valence, but not arousal or the zEMG response. The neuroimaging results indicate that reappraisal-related prefrontal and cingulate regions were recruited in both the up- and down-regulation conditions, while the bilateral occipital lobe was more active in the up-regulation than in the down-regulation. The psychophysiological interaction analysis revealed that the prefrontal-subcortical (amygdala and ventral striatal) connections were primarily recruited during up-regulation. This study expands the research on emotion regulation and enhances the understanding of the mechanisms underlying the cognitive regulation of positive emotion.
尽管众多研究已对情绪调节展开调查，但积极情绪调节的生理反应和神经基础仍不明确。为解决这一问题，我们在三项独立实验中使用相同材料，探究了重新评价对主观体验、颧肌肌电图（zEMG）反应和血氧水平反应的影响。在行为层面，上调积极情绪会增加效价、唤醒度和zEMG反应，而下调积极情绪则会降低效价，但不会降低唤醒度或zEMG反应。神经影像学结果表明，在上调和下调两种情况下均会激活与重新评价相关的前额叶和扣带区域，而上调时双侧枕叶比下调时更活跃。心理生理交互分析显示，前额叶 - 皮层下（杏仁核和腹侧纹状体）连接主要在情绪上调过程中被激活。本研究扩展了对情绪调节的研究，并增进了对积极情绪认知调节潜在机制的理解。
