在 4 个实验中，作者研究了熟悉环境中的空间更新。参与者了解房间中物体的位置，走到中心，转向适当的面向方向，然后做出相对方向判断（例如，“想象你站在 X 处，面向 Y。指向 Z。”）或以自我为中心的指向判断（例如，“你面向 Y。指向 Z。”）。实验操纵了学习航向和想象航向之间的角度差异以及实际航向和想象航向之间的角度差异。当想象的方向与学习视图平行时，即使参与者面向其他方向，并且当实际和想象的方向相同时，指向性能最好。房间的几何形状不影响这些结果。这些发现表明，记忆中的空间参考方向在运动过程中没有更新。
In 4 experiments, the authors investigated spatial updating in a familiar environment. Participants learned locations of objects in a room, walked to the center, and turned to appropriate facing directions before making judgments of relative direction (e.g., "Imagine you are standing at X and facing Y. Point to Z.") or egocentric pointing judgments (e.g., "You are facing Y. Point to Z."). Experiments manipulated the angular difference between the learning heading and the imagined heading and the angular difference between the actual heading and the imagined heading. Pointing performance was best when the imagined heading was parallel to the learning view, even when participants were facing in other directions, and when actual and imagined headings were the same. Room geometry did not affect these results. These findings indicated that spatial reference directions in memory were not updated during locomotion.
