The emotion-associated bodily sensation map is composed of a specific topographical distribution of bodily sensations to categorical emotions. The present study investigated whether or not interoceptive accuracy was associated with topographical changes in this map following emotion-induced bodily sensations. This study included 31 participants who observed short video clips containing emotional stimuli and then reported their sensations on the body map. Interoceptive accuracy was evaluated with a heartbeat detection task and the spatial patterns of bodily sensations to specific emotions, including anger, fear, disgust, happiness, sadness, and neutral, were visualized using Statistical Parametric Mapping (SPM) analyses. Distinct patterns of bodily sensations were identified for different emotional states. In addition, positive correlations were found between the magnitude of sensation in emotion-specific regions and interoceptive accuracy across individuals. A greater degree of interoceptive accuracy was associated with more specific topographical changes after emotional stimuli. These results suggest that the awareness of one's internal bodily states might play a crucial role as a required messenger of sensory information during the affective process.
与情绪相关的身体感觉图谱由身体感觉对分类情绪的特定地形分布组成。本研究调查了内感受准确性是否与情绪诱发的身体感觉后该图谱的地形变化相关。本研究包括31名参与者，他们观看包含情绪刺激的短视频片段，然后在身体图谱上报告他们的感觉。使用心跳检测任务评估内感受准确性，并使用统计参数映射（SPM）分析将身体感觉对特定情绪（包括愤怒、恐惧、厌恶、快乐、悲伤和中性）的空间模式可视化。针对不同情绪状态识别出了不同的身体感觉模式。此外，在个体中，特定情绪区域的感觉强度与内感受准确性之间发现了正相关。更高程度的内感受准确性与情绪刺激后更特定的地形变化相关。这些结果表明，对自身内部身体状态的感知可能在情感过程中作为感觉信息的必要传递者发挥关键作用。
