我们研究了一个高度熟悉的环境空间，一个人的居住城市，是如何在内存中表示。26名参与者面对他们家乡的照片般逼真的虚拟模型，并完成了一项任务，其中他们从各个方向指向熟悉的目标位置。每个参与者的表现是最准确的，当他或她面对北，和错误增加参与者的偏离朝北的方向增加。指向错误和延迟与参与者的初始位置和目标位置之间的距离无关。我们的研究结果是不一致的帐户的方向无关的记忆和理论假设的存储空间知识取决于当地的参考框架。虽然参与者在他们最初的位置认识到熟悉的当地景观，但他们的指向策略依赖于一个单一的、面向北方的参考框架，这可能是从地图上获得的，而不是从日常探索中获得的经验。尽管参与者花在城市导航上的时间比看地图的时间要多得多，但他们的指向行为似乎依赖于一个面向北方的心理地图。
We examined how a highly familiar environmental space-one's city of residence-is represented in memory. Twenty-six participants faced a photo-realistic virtual model of their hometown and completed a task in which they pointed to familiar target locations from various orientations. Each participant's performance was most accurate when he or she was facing north, and errors increased as participants' deviation from a north-facing orientation increased. Pointing errors and latencies were not related to the distance between participants' initial locations and the target locations. Our results are inconsistent with accounts of orientation-free memory and with theories assuming that the storage of spatial knowledge depends on local reference frames. Although participants recognized familiar local views in their initial locations, their strategy for pointing relied on a single, north-oriented reference frame that was likely acquired from maps rather than experience from daily exploration. Even though participants had spent significantly more time navigating the city than looking at maps, their pointing behavior seemed to rely on a north-oriented mental map.
