【摘要】：正空间导航是指人在不同地点之间移动时,基于自身和环境线索判断路线的一种能力,它包含多个复杂认知和感知过程[1]。人在自身熟悉的环境中移动时,需要依赖不同的空间表征,包括两种基本的表征方式[2]:自我参照导航以自身位置为中心解码空间信息来保持移动时的方向感,其结构基础主要位于尾状核、顶下小叶[3]。空间参照导航依赖于认知地图,要求人以探索性的视角记忆并分析整个空间的
[Abstract]:Positive space navigation refers to the ability of people to judge routes based on their own and environmental cues when they move between different places. It includes multiple complex cognitive and perceptual processes [1] .When people move in their familiar environment, It depends on different spatial representations, including two basic representations [2]: Self-referencing navigation decodes spatial information centered on one's own position to maintain a sense of direction when moving, and its structural basis is mainly located in the caudate nucleus. Subparietal lobules [3]. Spatial referential navigation depends on cognitive maps, requiring people to memorize and analyze the entire space from an exploratory perspective
