Is Working Memory Involved in the Transcribing and Editing of Texts?

Generally, researchers agree that that verbal working memory plays an important role in cognitive processes involved in writing. However, there is disagreement about which cognitive processes make use of working memory. Kellogg has proposed that verbal working memory is involved in translating but not in editing or producing (i.e., typing) text. In this study, the authors used articulatory suppression, a technique that reduces working memory to explore this question. Twenty participants transcribed six texts from one computer window to another, three of the texts with articulatory suppression and three without. When participants were in the articulatory suppression condition, they transcribed significantly more slowly and made significantly more errors than they did in the control condition. Implications for Kellogg’s proposal are discussed.
