Mindfulness meditation has been reported to reduce stress and enhance well-being. However, its effects on heart rate variability (HRV)-a physiological marker of stress-remain underexplored. This study aimed to examine how meditation practice is associated with subjective stress, HRV, and their interaction, using mobile health technologies. This 3-week observational study included 90...

Researchers have suggested that interoception can trigger autobiographical memory retrieval or affect the subjective sense of retrieval mode (e.g., involuntary or voluntary). This study examined whether 8-week mindfulness training aimed at improving interoceptive processing can alter autobiographical memory retrieval and perceived retrieval mode. Participants in the mindfulness group (n = 26)...

Mindfulness meditation, comprising focused attention and open monitoring meditations, has been shown to enhance performance on cognitive interference tasks. While this enhancement has been considered not to result from distractor inhibition, no empirical evidence has been provided through behavioral data. In this study, we investigated whether 30-min interventions of focused attention and open...

Mindfulness meditation consists of focused attention meditation (FAM) and open monitoring meditation (OMM), both of which reduce activation of the default mode network (DMN) and mind-wandering. Although it is known that FAM requires intentional focused attention, the mechanisms of OMM remain largely unknown. To investigate this, we examined striatal functional connectivity in 17 experienced...
