Recent research demonstrated that people represent spatial information configurally and preservation of configural cues at retrieval helps memory for spatial locations (Boduroğlu & Shah, Memory & Cognition, 37(8), 1120-1131 2009; Jiang, Olson, & Chun, Journal of Experimental Psychology: Learning, Memory, and Cognition, 26(3), 683-702 2000). The present study investigated the effects of spatial configurations on the resolution of individual location representations. In an open-ended task, participants first studied a set of object locations (three and five locations). Then, in a test display where available configural cues were manipulated, participants were asked to determine the original location of a target object whose color was auditorially cued. The difference between the reported location and the original location was taken as a measure of spatial resolution. In three experiments, we consistently observed that the resolution of spatial representations was facilitated by the preservation of spatial configurations at retrieval. We argue that participants may be using available configural cues in conjunction with the summary representation (e.g., centroid) of the original display in the computation of target locations.
近期研究表明，人们以构型方式表征空间信息，且在检索时保留构型线索有助于对空间位置的记忆（博杜罗卢 & 沙阿，《记忆与认知》，2009年第37卷第8期，第1120 - 1131页；江、奥尔森 & 春，《实验心理学杂志：学习、记忆与认知》，2000年第26卷第3期，第683 - 702页）。本研究考察了空间构型对个体位置表征分辨率的影响。在一项开放式任务中，参与者首先学习一组物体位置（三个和五个位置）。然后，在一个可操控可用构型线索的测试展示中，要求参与者确定一个颜色通过听觉提示的目标物体的原始位置。报告位置与原始位置之间的差异被用作空间分辨率的度量。在三个实验中，我们一致观察到，在检索时保留空间构型有助于空间表征的分辨率。我们认为，参与者在计算目标位置时可能会将可用的构型线索与原始展示的概要表征（例如，质心）结合使用。
