学习导航在人类和其他动物的生存中起着不可或缺的作用。关于人类导航的研究主要集中在我们如何有意识地绘制我们的世界。然而，我们中的许多人也有在“自动驾驶仪”上导航或出于习惯的经历。动物模型已经将这种认知映射与习惯学习识别为两个可分离的空间学习系统海马位置学习系统和纹状体反应学习系统。在这里，我们使用人类的这种二分法来理解导航风格的变化，通过证明空间编码过程中的大脑激活可以预测一个人的行为福尔斯落在从更灵活的认知地图式策略到更严格的习惯创造方法的连续体上。这些发现将从动物模型和人类行为研究中获得的丰富知识联系起来，为更全面地了解人类空间学习和导航的变化打开了大门。
Learning to navigate plays an integral role in the survival of humans and other animals. Research on human navigation has largely focused on how we deliberately map out our world. However, many of us also have experiences of navigating on “autopilot” or out of habit. Animal models have identified this cognitive mapping versus habit learning as two dissociable systems for learning a space—a hippocampal place-learning system and a striatal response-learning system. Here, we use this dichotomy in humans to understand variability in navigational style by demonstrating that brain activation during spatial encoding can predict where a person’s behavior falls on a continuum from a more flexible cognitive map-like strategy to a more rigid creature-of-habit approach. These findings bridge the wealth of knowledge gained from animal models and the study of human behavior, opening the door to a more comprehensive understanding of variability in human spatial learning and navigation.
