人类意识流的重要构成部分——心智游移

心智游移是指人类意识体验自发地被内源性的心理表征所占据的现象，又称为“白日梦”，是我们每个人每天都在不断经历着的意识状态。过去将心智游移看成人类注意系统的短板，随着对它的了解不断深入，今天的研究者开始更为全面地看待心智游移带给人类的损益。随着认知神经科学研究手段的日益发展，对脑的强烈兴趣为心智游移研究注入了更为强大的动力。研究者们认识到，心智游移是心智的工作方式，同时也是脑的内禀的、自组织的工作方式的重要体现。简要介绍了心智游移现象、其研究方法的进展以及目前对心智游移的基本观点，并对未来该领域的发展提出了一些看法。

Mind Wandering: One of the most important parts of the “stream of consciousness”

Mind wandering, or daydreaming, is referred to the phenomenon that the conscious experience of human being was spontaneously occupied by the internal mental representation, and it is such a ubiquitous status that everyone could experience everyday. Although mind wandering was regarded as the BUG in the attention system of human being, with the deeper and deeper understanding of mind wandering, the researchers have began to take a more comprehensive view of mind wandering, including its costs and benefits. Today the hot interest of the human brain energizes the study of mind wandering. Mind wandering is not only the working style of human mind, but also the embodiment of the intrinsic self-organization in the human brain. We describe the phenomenon of mind wandering, its research progress, and the principle view in this field. The prospect of the development in the research of mind wandering is given in the end.
