The inner voice in writing

This study explores the connection between writing and working memory, specifically the role of the subvocal articulatory rehearsal process (or inner voice). The authors asked the 18 participants to type sentences describing 24 multipanel cartoons. In some conditions, the participants were required to repeat a syllable continuously while writing. This activity, called articulatory suppression, interferes with the articulatory rehearsal process. Results indicated that interfering with the articulatory rehearsal process (or inner voice) interferes with writing by slowing the rate of writing, increasing mechanical errors, changing the temporal microstructure of text production, and increasing the perceived difficulty of the writing task. The authors applied their model of written text production to provide a theoretical account for these results.
