Interoception, which refers to sensing, interpreting, and integrating internal bodily signals, has been suggested to be associated with emotion regulation. Previous research has demonstrated individual differences in interoception and its impact on emotion regulation. However, the priming effect of interoception on emotion regulation and the underlying neural mechanisms remain unknown. This study aims to examine how interoception primes different strategies of cognitive reappraisal, using electroencephalography (EEG). Thirty-seven healthy participants completed an interoceptive priming task. We found that interoception increased the amplitudes of the late positive potential (LPP) during both interpretation and detachment strategies. The priming effect of interoception in enhancing LPP amplitudes lasted longer for interpretation than for detachment. A decrease in alpha power during reinterpretation was observed after interoceptive priming, but not during detachment. The results revealed that interoception enhanced attention to bodily signals associated with negative emotions during cognitive reappraisal. Interoception showed distinct effects on different strategies of cognitive reappraisal, with different underlying neural mechanisms. Interoception-based programs may be an effective way to enhance the capacity for cognitive reappraisal.
内感受指的是感知、解释和整合身体内部信号，研究表明其与情绪调节有关。以往研究已经证实了内感受存在个体差异及其对情绪调节的影响。然而，内感受对情绪调节的启动效应及其潜在神经机制仍不清楚。本研究旨在使用脑电图（EEG）来检验内感受如何启动不同的认知重评策略。37名健康参与者完成了一项内感受启动任务。我们发现，在内感受启动下，无论是在解释策略还是分离策略中，内感受都增加了晚期正电位（LPP）的波幅。内感受对增强LPP波幅的启动效应在解释策略中持续的时间比对分离策略更长。在内感受启动后，重新解释过程中观察到阿尔法波功率下降，但在分离过程中未观察到。结果表明，在内感受启动下，认知重评过程中内感受增强了对与负面情绪相关的身体信号的注意力。内感受对不同的认知重评策略有不同的影响，且具有不同的潜在神经机制。基于内感受的干预方案可能是增强认知重评能力的有效途径。
