It has been documented that when memorizing a physical space, the person's mental representation of that space is biased with distortion and segmentation. Two experiments reported here suggest that distortion and segmentation arise due to a hierarchical organization of the spatial representation. The spatial relations associated with salient landmarks are more strongly encoded and easier to recall than those associated with non-salient landmarks. In the presence of multiple salient landmarks, multiple intrinsic frames of reference are formed and spatial relations are anchored to each individual frame of reference. Multiple such representations may co-exist and interactively determine a person's spatial performance.
已有文献记录表明，当人们记忆一个物理空间时，他们对该空间的心理表征会存在扭曲和分割现象。本文报道的两项实验表明，这种扭曲和分割现象源于空间表征的层级组织。与显著地标相关的空间关系比与非显著地标相关的空间关系更容易被编码和回忆。在存在多个显著地标时，会形成多个内在参考系，并且空间关系会被锚定到每个单独的参考系上。可能会存在多个这样的表示形式，并且它们会相互作用，共同决定一个人的空间表现。
