At the heart of social cognition is our ability to distinguish between self and other and correctly attribute mental and affective states to their origin. Emotional egocentricity bias (EEB) reflects the tendency to use one's own emotional state when relating to others. Although interoception underpins our emotional experience, little is known about its role on how we affectively relate to others. Here, we assessed how cardiac interoceptive impact, manipulated by presenting affective stimuli across different phases of the cardiac cycle coupled with trait-like levels of interoceptive accuracy, modulate the EEB. Individuals with higher interoceptive accuracy displayed an increased EEB when the other's emotional state was presented at the point of maximum interoceptive impact (i.e., at systole), whereas the reverse was observed for individuals with lower interoceptive accuracy. These findings show how interoceptive activity provides the physiological context within which we process other's emotional states in parallel to ours.
社会认知的核心在于我们区分自我与他人，并将心理和情感状态正确归因于其来源的能力。情感自我中心偏差（EEB）反映了在与他人交往时使用自身情感状态的倾向。尽管内感受是我们情感体验的基础，但对于它在我们如何与他人进行情感关联方面所起的作用却知之甚少。在此，我们评估了通过在心动周期的不同阶段呈现情感刺激以及类似特质水平的内感受准确性来操纵的心脏内感受影响如何调节情感自我中心偏差。当在最大内感受影响点（即收缩期）呈现他人的情感状态时，内感受准确性较高的个体表现出增强的情感自我中心偏差，而内感受准确性较低的个体则观察到相反的情况。这些发现表明内感受活动如何提供生理背景，在此背景下我们在处理他人情感状态时与自身情感状态并行。
