Which statement best describes the Central Executive's role?

• A. Domain-general attentional controller that directs attention, switches tasks, updates working memory, and coordinates sub-systems
• B. Stores visual imagery briefly
• C. Serves as a long-term memory store
• D. Primarily handles auditory rehearsal

Answer: (A)

The Central Executive is the domain-general control system of working memory. It doesn’t store information itself; instead, it directs attention, switches between tasks, updates the contents of working memory, and coordinates the different storage subsystems as needed. It manages cognitive resources, inhibits irrelevant information, and retrieves or integrates information from long-term memory when required, often working with the episodic buffer to combine inputs into coherent representations. This control role is why the description focusing on attention management, task-switching, updating WM, and coordinating subsystems fits best. The other statements describe specific stores: the visual imagery is held by the visuospatial sketchpad, long-term memory is a separate store, and auditory rehearsal is a function of the phonological loop.
