What is working memory?

• A. Information drawn from long-term memory and kept accessible for use
• B. Sensory details stored briefly and then overwritten
• C. The permanent store of all knowledge
• D. A passive repository with no active use

Answer: (A)

Working memory is the part of memory you use to hold and actively process information you need right now. It keeps relevant details accessible by pulling them from your long-term memory as needed, so you can reason, plan, follow instructions, or solve problems in the moment. It’s an active, temporary workspace, not a permanent store.

This differs from long-term memory, which stores knowledge more permanently, and from sensory memory, which only briefly holds sensory details. Working memory’s power comes from its ability to maintain and manipulate information rather than just store it. Think of doing mental math, following a multi-step directions sequence, or keeping a phone number in mind while you dial—these are all working-memory tasks. The capacity is limited, so you can typically handle only a few items at once, and the process involves actively maintaining and sometimes retrieving items from long-term memory to use them now.
