The way we perceive signals coming from the inside of the body (i.e., interoception) may influence the processing of information related to the self. In this study, we investigated whether interoceptive sensibility may play a role in autobiographical memory processes. We evaluated 41 healthy participants with a modified version of the Autobiographical Memory Test, also assessing specificity, vividness, emotional valence, and intensity for autobiographical and public memories. Participants completed a self-report questionnaire measuring interoceptive sensibility. Results showed that autobiographical memories were recalled with higher specificity, vividness, and emotional intensity than public memories. Interestingly, we found that participants with (self-reported) high interoceptive sensibility recalled more positive events in the autobiographical compared to the public condition. Our findings provided new evidence on the selective role of physiological aspects of bodily self-awareness in autobiographical memory, suggesting that interoception is fundamental for supporting adaptive emotion regulation processes when recollecting engrams related to the self.
我们感知身体内部信号的方式（即内感受）可能会影响与自我相关的信息处理。在这项研究中，我们调查了内感受敏感性是否可能在自传体记忆过程中发挥作用。我们用自传体记忆测试的一个改良版本评估了 41 名健康参与者，同时评估了自传体和公共记忆的特异性、生动性、情绪效价和强度。参与者完成了一份自我报告问卷，测量内感受敏感性。结果表明，自传体记忆比公共记忆具有更高的特异性、生动性和情绪强度。有趣的是，我们发现（自我报告的）内感受敏感性高的参与者在自传体记忆中比在公共条件下回忆起更多的积极事件。我们的发现为身体自我意识的生理方面在自传体记忆中的选择性作用提供了新的证据，表明内感受对于支持回忆与自我相关的印痕时的适应性情绪调节过程是至关重要的。
