在冥想的实践中，自我产生和自发的思维以及头脑偏离冥想预定目标的倾向是无处不在的，这构成了冥想的基本教义之一：高度意识到我们的注意力放在哪里，以及意识到我们头脑中的内容。冥想背景下的走神为个人提供了一个独特而亲密的机会来仔细检查走神的本质，培养对正在进行的思维模式的意识，同时培养平静(脾气或性情的平和)和对思想、解释和身体感觉的内容的同情。在这篇综述中，我们提供了一个理论框架，强调了冥想实践影响自发思维背后的神经和现象学过程的神经认知机制。我们的理论模型侧重于几种汇聚机制：元意识在促进对自发思维过程的时刻到时刻的觉察中的作用，冥想练习对涉及注意力和情绪调节的自上而下认知过程和自下而上感觉过程的关键结构的影响，以及冥想练习对潜在知觉和知觉分离的神经基础的影响。
During the practice of meditation, the occurrence of self-generated and spontaneous thought and the tendency of the mind to wander away from the intended goal of meditation is ubiquitous, and comprises one of the fundamental teachings of meditation: a heightened awareness of where our attention is placed, and an awareness of the contents of our mind. Mind-wandering in the context of meditation provides individuals a unique and intimate opportunity to closely examine the nature of the wandering mind, cultivating an awareness of ongoing thought patterns while simultaneously cultivating equanimity (evenness of temper or disposition) and compassion towards the content of thoughts, interpretations, and bodily sensations. In this review we provide a theoretical framework highlighting the neurocognitive mechanisms by which contemplative practices influence the neural and phenomenological processes underlying spontaneous thought. Our theoretical model focuses on several converging mechanisms: the role of meta-awareness in facilitating an increased moment to moment awareness of spontaneous thought processes, the effects of meditation practice on key structures underlying both the top-down cognitive processes and bottom-up sensory processes implicated in attention and emotion regulation, and the influence of contemplative practice on the neural substrates underlying perception and perceptual decoupling.
