The central executive is best described as?

• A. A single module that handles all processing.
• B. A set of control processes including updating, shifting, and inhibition.
• C. A long-term memory system.
• D. A passive storage area.

Answer: (B)

The central executive is the attentional control component of working memory. It doesn’t store information or act as a single processing module; instead, it supervises and coordinates cognitive operations. Its job is to direct attention, decide what to update in working memory, switch between tasks, and inhibit competing or irrelevant information. These control functions are usually described as updating, shifting, and inhibition, which explains why this part is characterized as a set of control processes. It works alongside the storage components (like the phonological loop and visuospatial sketchpad) and the episodic buffer, rather than being a long‑term memory system or a passive storage area.
