How does the working memory model differ from the multi-store model?

• A. The WM model treats memory as a single store with uniform properties.
• B. The WM model provides a more detailed understanding of short-term memory processes.
• C. The WM model denies any rehearsal processes.
• D. The WM model has fewer components than the multi-store model.

Answer: (B)

The main idea being tested is how the working memory model expands our view of short-term memory compared with the multi-store model by detailing how information is processed and managed, not just stored.

The working memory model breaks short-term memory into multiple components that handle different kinds of information and operations. There’s a central executive that directs attention and coordinates processing, a phonological loop that holds and rehearses verbal data, a visuospatial sketchpad that manages visual and spatial information, and an episodic buffer that integrates information and links it to long-term memory. This setup shows short-term memory as an active system where we manipulate and shuttle information around, not just store it for a moment. Rehearsal isn’t the sole, blanket mechanism; it’s task-specific within the phonological loop, while other components take care of different types of processing.

In contrast, the multi-store model presents memory as distinct stores—a sensory store, a single short-term store, and a long-term store—where rehearsal mainly helps transfer information from short-term to long-term memory. It treats short-term memory more as a passive holding bin rather than a dynamic processor.

So the statement that the WM model provides a more detailed understanding of short-term memory processes best captures what sets it apart. The other ideas don’t fit because the WM view isn’t a single store, it does include rehearsal in a nuanced way, and it actually adds components rather than reducing them.
