工作记忆中的言语-空间关联可以索引抽象信息的核心容量，其在同时保留的量中是有限的。然而，那些看起来像是联想的抽象表征却可以反映出单独持有的语言和空间代码，然后并行使用。我们在两个实验中研究了这个问题，这两个实验是关于名字和空间位置之间的关联的记忆，两者之间有或没有一一对应。参与者（9-10岁和12-13岁的儿童和大学生）看到一系列的名字在空间位置所占据的房子图标，并指出在该位置的探测器名称出现。只有成年人受益于1对1的名称和位置之间的对应关系，这种好处是消除发音抑制。我们认为，1对1的好处源于语言和空间代码的并行使用。没有排练，表现似乎索引工作记忆的抽象，跨模态的信息。与其他任务的相关性表明，它是衡量工作记忆容量的一个很好的方法。(c)2006爱思唯尔公司All rights reserved.
Verbal-to-spatial associations in working memory may index a core capacity for abstract information limited in the amount concurrently retained. However, what look like associative, abstract representations could instead reflect verbal and spatial codes held separately and then used in parallel. We investigated this issue in two experiments on memory for associations between names and spatial locations, with or without a 1-to-1 correspondence between the two. Participants (children 9-10 and 12-13 years old and college students) saw series of names presented at spatial locations occupied by house icons and indicated the location at which a probe name had appeared. Only adults benefited from 1-to-1 correspondence between names and locations, and this benefit was eliminated by articulatory suppression. We maintain that the 1-to-1 benefit stems from verbal and spatial codes used in parallel. Without rehearsal, performance appears to index working memory for abstract, cross-modal information. Correlations with other tasks suggest that it is an excellent measure of working memory capacity. (c) 2006 Elsevier Inc. All rights reserved.
