两个实验研究了空间记忆的结构。受试者学习空间布局中对象的位置（实验1）或地图上对象名称的位置（实验2）。在这些空间阵列中不存在物理和感知边界。然后，受试者参加了三个任务：项目识别，其中感兴趣的变量是空间启动;自由和线索回忆;和欧几里得距离估计。对个体受试者回忆协议的有序树分析产生了与输出顺序一致的层次树。空间启动和距离估计依赖于是否对对象出现在同一子树或不同的子树。这些发现表明，空间记忆有一个层次的组成部分，即使物理和感知的边界是不存在的。引发也增加了有序树的聚类深度。这一结果支持了激活扩散理论的提取，但提供了证据反对几个“非激活扩散”的理论。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Two experiments investigated the structure of spatial memories. Subjects learned locations of objects in spatial layouts (Experiment 1) or locations of object names on maps (Experiment 2). Physical and perceptual boundaries were absent in these spatial arrays. Subjects then participated in three tasks: item recognition, in which the variable of interest was spatial priming; free and cued recall; and Euclidean distance estimation. Ordered-tree analysis of individual subjects' recall protocols produced hierarchical trees consistent with regularities in output order. Spatial priming and distance estimations depended on whether pairs of objects appeared in the same subtree or in different subtrees. These findings indicate that spatial memories have a hierarchical component, even when physical and perceptual boundaries are nonexistent. Priming also increased with depth of clustering in ordered trees. This result supports spreading-activation theories of retrieval but provides evidence against several" non-spreading-activation" theories.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
