Theories of emotion consider the self-perception of visceral activity to play an important role in emotion. This study examined the relationship between interoceptive sensitivity and both the subjective emotional experience and the processing of emotional pictures. According to their results in a heartbeat detection task subjects were classified as good (N = 17) or poor (N = 20) heartbeat perceivers. Event-related potentials were recorded while subjects viewed pleasant, neutral and unpleasant pictures and SAM ratings were examined. Good heartbeat perceivers showed significantly greater P300 and slow wave amplitudes for emotional pictures at antero-inferior, medial and posterior electrode sites and experienced a greater arousal for emotional pictures compared to poor heartbeat perceivers. The heartbeat perception score correlated significantly positive both with emotional P300 and slow wave amplitudes as well as with the arousal ratings for emotional pictures. The results indicate that there is a significant and strong association between interoceptive sensitivity and the intensity of emotional experience as well as the central processing of emotional stimuli.
情绪理论认为，对内脏活动的自我感知在情绪中起着重要作用。本研究考察了内感受敏感性与主观情绪体验以及情绪图片加工之间的关系。根据在心跳检测任务中的结果，将受试者分为心跳感知良好组（N = 17）和心跳感知较差组（N = 20）。在受试者观看愉悦、中性和不愉快图片时记录事件相关电位，并检查自我评估模拟人（SAM）评分。与心跳感知较差的受试者相比，心跳感知良好的受试者在前下、内侧和后电极部位对情绪图片表现出显著更大的P300和慢波振幅，并且对情绪图片有更大的唤醒反应。心跳感知分数与情绪P300和慢波振幅以及情绪图片的唤醒评分均呈显著正相关。结果表明，内感受敏感性与情绪体验强度以及情绪刺激的中枢加工之间存在显著且强烈的关联。
