What is the Working Memory Model (WMM)?

• A. An elaboration of the short-term store from the multi-store model describing information temporarily stored in consciousness that can be manipulated.
• B. A theory about long-term memory.
• C. A model of sensory memory.
• D. A theory about encoding in the hippocampus.

Answer: (A)

The Working Memory Model treats short-term memory as a dynamic workspace rather than a single passive store. It was created to explain how we both hold and actively manipulate information during tasks like reasoning, comprehension, and learning. Building on the idea from the multi-store model that there is a short-term store, the WMM elaborates it into multiple components that handle different kinds of information and coordinate their use.

Key parts include the central executive, which directs attention and integrates information; the phonological loop, which briefly holds verbal information and uses subvocal rehearsal; the visuospatial sketchpad, which handles visual and spatial data; and the episodic buffer, which binds different types of information into a coherent sequence and links to long-term memory. Together, they describe how information is temporarily stored and transformed in the moment.

That's why this choice is correct: it accurately describes the WMM as an elaboration of the short-term store from the multi-store model, focusing on information held in consciousness that can be manipulated. The other options point to long-term memory, sensory memory, or neural encoding in the hippocampus, which are not what the Working Memory Model primarily addresses.
