Working memory test
Hold patterns and sequences in mind for a few seconds and reproduce them. Working memory is the mental workspace behind reasoning and learning.

What working memory is
Working memory holds information briefly while you use it: a phone number while you dial, the steps of a calculation, the rules of a puzzle you're testing. It's closely linked to fluid reasoning, because complex problems require keeping several pieces in mind at once.
The question types
- Spatial span: some squares light up; tap all of them once they disappear.
- Corsi blocks: squares flash one at a time; repeat the sequence in the same order. Sequences grow from four squares to eight. The Corsi block-tapping task has been used in psychology since the 1970s.
- Shape–location binding: several shapes appear in a grid; pick the layout that is exactly the same.
Tips
- Group squares into a shape or picture; it's far easier than remembering separate dots.
- For sequences, trace the path as a line or say it as a rhythm in your head.
Frequently asked questions
How many items can people hold in working memory?
Typically about four meaningful chunks at once. Grouping items into larger chunks is the main way people remember more.
