What is the proposed capacity of the Episodic Buffer?

• A. About 2 chunks.
• B. About 4 chunks.
• C. About 6 chunks.
• D. About 8 chunks.

Answer: (B)

This question hinges on how much information the Episodic Buffer can hold at once. The Episodic Buffer was proposed to be a temporary store that combines input from the phonological loop, visuospatial sketchpad, and long-term memory into a single, time-ordered representation. Its capacity is about four chunks. That fits its role as a small but flexible workspace: bigger than the individual short-term stores’ limits, yet limited enough to keep the integrated episode coherent. So four chunks is the best estimate. Options suggesting only about two chunks underestimate its ability to bind different sources; larger estimates like six or eight chunks exceed the proposed limit and would undermine its role in maintaining a stable, integrated episode.
