以往的研究表明，空间记忆的小布局的记忆是方向依赖（方向特定），但大布局的记忆是方向无关（方向自由）。两个实验研究了布局大小和方向依赖性之间的关系。参与者学习了一个小的或大的4点路径（实验1）或一个大的显示对象（实验2），然后从想象的标题是相同或不同的单一研究方向的相对方向的判断。当想象的航向与研究的方向相同时，判断更快更准确（即，对准）比想象的航向与研究的方位不同时（即，未对准）。这种对齐效应在小型和大型布局中都存在。这些结果表明，位置编码的方向依赖的方式，无论布局大小。
Previous research on spatial memory indicated that memories of small layouts were orientation dependent (orientation specific) but that memories of large layouts were orientation independent (orientation free). Two experiments investigated the relation between layout size and orientation dependency. Participants learned a small or a large 4-point path (Experiment 1) or a large display of objects (Experiment 2) and then made judgments of relative direction from imagined headings that were either the same as or different from the single studied orientation. Judgments were faster and more accurate when the imagined heading was the same as the studied orientation (i.e., aligned) than when the imagined heading differed from the studied orientation (i.e., misaligned). This alignment effect was present for both small and large layouts. These results indicate that location is encoded in an orientation-dependent manner regardless of layout size.
