Which scenario exemplifies the articulatory rehearsal process in short-term memory according to Baddeley's model?

The answer representing the articulatory rehearsal process in short-term memory focuses on the act of silently repeating information to retain it for a brief period. In Baddeley's model, the articulatory rehearsal component is responsible for maintaining verbal information in the phonological loop—a subsystem of working memory. When a student silently repeats what the instructor has said, they are engaging this rehearsal mechanism, which helps to encode the information better and keep it active in short-term memory for immediate retrieval later, such as when they write it down.

This process contrasts with the other scenarios provided. Discussing lecture content with classmates involves externalizing information and may not specifically target the rehearsal of verbal information. Listening to a recording of the lecture multiple times mainly relies on auditory processing rather than silent repetition. Finally, taking notes after class does not involve the active rehearsal of information; it is more about transferring knowledge to a permanent format rather than temporarily retaining it in short-term memory. Thus, the act of silently repeating what the instructor has said captures the essence of the articulatory rehearsal process in short-term memory efficiently.
