两个实验研究了用于指定对象在内存中的位置的空间参考方向是否可以单独由布局几何确定。参与者从单一视角研究物体的布局，同时记录他们的眼球运动。随后，参与者使用记忆来判断相对方向（例如，“想象你站在X，面对Y，请指向Z”）。当布局的对称轴与被试的观察方向不同时，学习过程中眼睛对物体的注视顺序和指向判断中的偏好方向都由对称轴的方向决定。这些结果提供了进一步的证据，对象间的空间关系表示在内存与内在的参考框架。
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 judgment, 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.
