Abstract
Verbal working memory may combine phonological and conceptual units. We disentangle their contributions by extending a prior procedure (Chen & Cowan, 2005) in which items recalled from lists of previously seen word singletons and of previously learned word pairs depended on the list length in chunks. Here we show that a constant capacity of about 3 chunks holds across list lengths and list types, provided that covert phonological rehearsal is prevented. What remains is a core verbal working-memory capacity.
摘要
言语工作记忆可能会整合语音和概念单元。我们通过扩展之前的一个程序（Chen & Cowan，2005）来区分它们的作用，在该程序中，从之前看到的单个单词列表和之前学习的单词对列表中回忆出的项目取决于组块中的列表长度。在这里我们表明，只要防止隐蔽的语音复述，大约3个组块的恒定容量在不同的列表长度和列表类型中都是成立的。剩下的就是核心言语工作记忆容量。
