How does the WMM relate to the multi-store model (MSM)?

• A. The WMM elaborates on components of the MSM by focusing on processes rather than just structure.
• B. The MSM explains all cognitive processes in full detail.
• C. The WMM rejects MSM.
• D. The MSM includes the central executive as its primary component.

Answer: (A)

The Working Memory Model expands what the Multi-Store Model says about short-term memory by showing that processing comes from several interacting parts rather than a single short-term store. The MSM treats short-term memory as a simple temporary holding place that transfers information to the long-term store with rehearsal. The WMM keeps the idea of separate stores but adds a dynamic system: a central executive that directs attention and coordinates processing, a phonological loop for verbal information with subvocal rehearsal, a visuospatial sketchpad for visual and spatial data, and an episodic buffer that integrates across modalities and links to long-term memory. So, it doesn’t replace the MSM; it elaborates it by focusing on how information is processed and manipulated within short-term memory, not just stored.
