One assessment of embodiment is the rubber hand illusion (RHI), a visuo-tactile illusion in which individuals attribute a sense of ownership to a rubber hand and disownership to their real hand. Interestingly, interoception seems to influence RHI susceptibility. In this study, we administered the RHI and the Multidimensional Assessment of Interoceptive Awareness (MAIA) to examine embodiment experiences and interoceptive awareness in experienced meditators (n = 15) and non-meditators (n = 15). We found that meditators reported less intensity in rubber hand ownership, but there was no significant difference between groups with respect to disownership of their real hand or drift in finger proprioception. Moreover, we found, from our MAIA results, that disownership experiences were associated with a feeling of trusting one's body in non-meditators and with the ability to maintain attention to unpleasant bodily sensations in meditators. These results suggest a unique relationship between interoceptive awareness and embodiment related to meditation.
一种对具身性的评估是橡胶手错觉（RHI），这是一种视触错觉，个体将一种归属感赋予橡胶手，而将不归属感赋予自己的真实手。有趣的是，内感受似乎会影响 RHI 的易感性。在这项研究中，我们进行了 RHI 和多维内感受意识评估（MAIA），以检查经验丰富的冥想者（n=15）和非冥想者（n=15）的具身体验和内感受意识。我们发现冥想者报告的橡胶手归属感的强度较低，但两组在真实手的不归属感或手指本体感受的漂移方面没有显著差异。此外，从我们的 MAIA 结果中发现，非冥想者的不归属体验与对身体的信任感有关，而冥想者的不归属体验与保持对不愉快身体感觉的注意力的能力有关。这些结果表明，内感受意识和与冥想相关的具身性之间存在独特的关系。
