What is Working Memory?
/ˈwɜːkɪŋ ˈmeməri/
The cognitive system that temporarily holds and manipulates information needed for complex tasks such as reasoning, comprehension, and learning. The brain's mental "scratchpad."

Everyday Example
When you hold a phone number in mind while dialling, multiply 23 × 7 in your head, or follow a recipe while cooking — that's your working memory. It holds information active long enough for you to use it.
publicReal-World Application
“Chess grandmasters don't have better working memories than average people — research shows they have similar raw capacity. Their advantage is in pattern recognition: they've chunked thousands of positions, so each "piece" in working memory holds more information.”

Did you know?
Alan Baddeley and Graham Hitch proposed the working memory model in 1974, replacing the simpler "short-term memory" concept. It consists of a central executive, phonological loop, visuospatial sketchpad, and episodic buffer.

Key Insight
Working memory capacity is one of the strongest predictors of academic performance — stronger than IQ in some studies. But crucially, it can be trained. Strategies like chunking, rehearsal, and sleep dramatically improve effective capacity.
