区分自我和他人对于自我意识和社会交往是必要的。这种区别被认为取决于视觉反馈主导的多感觉整合。然而，自我意识也依赖于内感受信号的处理。我们对比了自我的外感受性和内感受性模型，以研究迄今为止尚未探索的外部和内部自我感知之间的相互作用。自我和他人之间的多感官刺激被用来诱导一个人的身份表征的控制变化。内感受敏感性预测的可塑性的自我表征的多感官整合的行为，生理和内省的反应，表明内感受在自我识别系统中起着关键的调节作用。特别是，只有低内感受性敏感度的参与者在多感官刺激下经历了自我-他人边界的变化。这些结果支持内感受性预测编码模型被用来监测和分配的来源的感觉输入无论是自我或他人，以及支持的假设，岛叶皮层作为一个收敛区的处理和全球代表性的材料自我参与内感受性的感觉，多感觉整合和自我处理。
Distinguishing self from other is necessary for self-awareness and social interactions. This distinction is thought to depend on multisensory integration dominated by visual feedback. However, self-awareness also relies on the processing of interoceptive signals. We contrasted the exteroceptive and interoceptive models of the self to investigate the hitherto unexplored interaction between the perception of the self from the outside and from within. Multisensory stimulation between self and other was used to induce controlled changes in the representation of one’s identity. Interoceptive sensitivity predicted the malleability of self-representations in response to multisensory integration across behavioral, physiological and introspective responses, suggesting that interoception plays a key modulating role in the self-recognition system. In particular, only participants with low interoceptive sensitivity experienced changes in self-other boundaries in response to multisensory stimulation. These results support the view that interoceptive predictive coding models are used to monitor and assign the sources of sensory input either to the self or to others, as well as support the hypothesis of the insular cortex as a convergence zone in the processing and global representation of the material self given its involvement in both interoceptive feelings, multisensory integration and self-processing.
