Two experiments investigated whether the spatial reference directions that are used to specify objects' locations in memory can be solely determined by layout geometry. Participants studied a layout of objects from a single viewpoint while their eye movements were recorded. Subsequently, participants used memory to make judgments of relative direction (e.g., "Imagine you are standing at X, facing Y, please point to Z"). When the layout had a symmetric axis that was different from participants' viewing direction, the sequence of eye fixations on objects during learning and the preferred directions in pointing judgments were both determined by the direction of the symmetric axis. These results provide further evidence that interobject spatial relations are represented in memory with intrinsic frames of reference.
两项实验探究了用于在记忆中指定物体位置的空间参考方向是否能仅由布局几何形状决定。参与者从单一视角研究物体布局，同时记录他们的眼动。随后，参与者利用记忆对相对方向进行判断（例如，“想象你站在X处，面向Y，请指向Z”）。当布局有一条与参与者观察方向不同的对称轴时，学习过程中对物体的眼动注视顺序以及指向判断中的偏好方向均由对称轴方向决定。这些结果进一步证明了物体间的空间关系在记忆中是以内在参考系来表征的。
