Mind wandering (MW) has been defined as the brain's default mode of operation. It is a common experience, however, that this process can become maladaptive, and take the form of repetitive thoughts. We aimed to compare the cardiac and cognitive correlates of perseverative cognition (PC) and MW. Seventy-three healthy participants were engaged in two recall interviews designed to draw their attention to a neutral and a personally relevant negative episode. After each interview, participants performed a 20-min tracking task with thought probe while the electrocardiogram was continuously recorded. Perseverative cognition was associated with higher levels of cognitive inflexibility (slower reaction times, highest intrusiveness, efforts to inhibit), autonomic rigidity (low heart rate variability), and mood worsening compared to being focused on task or MW. Results suggest that MW fails to serve its adaptive function, and turns into a risk factor for health whenever it becomes a rigid and inflexible pattern (PC).
思维漫游（MW）被定义为大脑的默认运行模式。然而，这种过程也可能变得适应不良，表现为重复的思维。我们旨在比较持续认知（PC）和 MW 的心脏和认知相关性。73 名健康参与者参与了两次回忆访谈，旨在引起他们对中性和个人相关的负面事件的注意。每次访谈后，参与者在进行 20 分钟的跟踪任务时进行思想探测，同时连续记录心电图。与专注于任务或 MW 相比，持续认知与更高的认知灵活性（较慢的反应时间、最高的侵入性、抑制努力）、自主僵化（低心率变异性）和情绪恶化相关。结果表明，MW 未能发挥其适应性功能，并且每当它变成一种僵化和不灵活的模式（PC）时，它就会成为健康的风险因素。
