Which process is responsible for rehearsing information stored in the phonological store?

• A. Visuo-spatial sketchpad
• B. Articulatory Process
• C. Phonological Loop
• D. Central Executive

Answer: (B)

Rehearsal of verbal information is done by the articulatory process, the inner voice part of the phonological loop. The phonological loop has a short-term store that holds speech-based items briefly and an articulatory rehearsal mechanism that refreshes those items through subvocal repetition. This refreshing keeps the information active long enough to be encoded or transferred, which is why verbal recall improves when you silently repeat items. If you’re asked to perform another repetitive task at the same time (articulatory suppression), this rehearsal is disrupted and verbal memory declines, highlighting that the articulatory process is what maintains information in the phonological store. The visuo-spatial sketchpad and the central executive play different roles and aren’t responsible for this phonological rehearsal.
