三个实验研究了记忆中用来代表环境空间结构的参考框架。参与者根据配置的内在轴来学习房间中物体的位置;轴与他们的视角不同或相同。使用记忆判断相对方向是最准确的想象标题平行于内在轴，即使它不同于观察角度，并没有成本学习布局根据一个非自我中心的轴。当布局的形状相对于学习的内在轴是双侧对称的时，与该轴正交的新标题比其他新标题更准确地被检索到。这些结果表明，空间记忆的定义相对于内在的参考框架，这是自我中心的经验和环境线索的基础上选择。
Three experiments investigated the frames of reference used in memory to represent the spatial structure of the environment. Participants learned the locations of objects in a room according to an intrinsic axis of the configuration; the axis was different from or the same as their viewing perspective. Judgments of relative direction using memory were most accurate for imagined headings parallel to the intrinsic axis, even when it differed from the viewing perspective, and there was no cost to learning the layout according to a nonegocentric axis. When the shape of the layout was bilaterally symmetric relative to the intrinsic axis of learning, novel headings orthogonal to that axis were retrieved more accurately than were other novel headings. These results indicate that spatial memories are defined with respect to intrinsic frames of reference, which are selected on the basis of egocentric experience and environmental cues.
