Which statement best captures a contribution of the WMM compared to MSM?

• A. It emphasizes processes and components rather than just storage structure.
• B. MSM explains all cognitive processes in full detail.
• C. The WMM rejects the concept of short-term memory.
• D. MSM is unable to explain any memory processes.

Answer: (A)

The main idea being tested is how the Working Memory Model shifts our understanding from a single short-term storage idea to a processing system with distinct parts. The WMM adds components—the central executive that directs attention, the phonological loop for verbal information, the visuospatial sketchpad for visual-spatial data, and later the episodic buffer—to show how we actively manipulate and coordinate information. This contrasts with the Multi-Store Model, which treats short-term memory as a single storage place with a more passive transfer to long-term memory. Because the WMM explains how different tasks can be handled simultaneously by engaging separate subsystems and by how processing and rehearsal interact, it captures a key contribution over the MSM. The other statements either mischaracterize MSM or the WMM: the MSM isn’t said to explain all cognitive processes in full detail, it doesn’t reject short-term memory, and the MSM does account for some memory processes even if it’s more limited in explaining processing.
