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.
在4项实验中，作者研究了在熟悉环境中的空间更新。参与者学习房间内物体的位置，走到房间中央，然后转向适当的朝向方向，再进行相对方向判断（例如，“想象你站在X处，面向Y。指向Z。”）或自我中心指向判断（例如，“你面向Y。指向Z。”）。实验操纵了学习方向与想象方向之间的角度差以及实际方向与想象方向之间的角度差。当想象方向与学习视角平行时，即使参与者面向其他方向，且实际方向与想象方向相同时，指向表现最佳。房间的几何形状并未影响这些结果。这些发现表明，运动过程中记忆中的空间参考方向并未更新。
