- 研究成果概要
- The present study aimed to elucidate whether and how meditation-based mental training would alter interoceptive awareness, i.e., sensitivity to one’s own bodily sensations. In Study 1, an advanced expert on contemplative practices and control participants naïve to meditation completed psychological scales on interoceptive awareness, trait mindfulness, subjective well-being, and trait anxiety. Compared with the control participants, the meditator self-reported significantly higher scores on multiple dimensions of interoceptive awareness including noticing, attention regulation, body listening, and trusting. The expert also reported higher scores on mindfulness and well-being and lower scores on anxiety. These case data are consistent with the notion that enhanced sensitivity to one’s own bodily states are associated with higher psychological well-being among contemplatives. Study 2 preliminarily examined whether interoceptive awareness may be deteriorated when staying in a microgravity environment. Participants who were not habitual meditators stayed either in a pool or on the ground for an hour, and performed on a heartbeat detection task before and after each stay. Significant changes in performance on heartbeat detection were not observed, although time-domain heart rate variability (RMSSD) increased after staying in the water. These data could be used in a future study to examine potential differences between meditators and non-meditators.
