Chimp Test
Numbers will appear on a grid. After you click the first one, the rest will be hidden. Click them in order from lowest to highest. 3 strikes and you're out.
FAQ
Yes. Research at Kyoto University by Tetsuro Matsuzawa showed that young chimpanzees can recall the positions of numbers with about 80% accuracy at speeds that humans cannot match, likely due to eidetic memory.
It measures visuospatial working memory — specifically the ability to quickly encode and retain the spatial positions of multiple items after brief exposure.
Matching 7-8 numbers consistently is average for humans. Reaching level 10+ puts you in the top percentile. Young chimps consistently reach level 9 with high accuracy.
About this test
The chimp test is based on groundbreaking research from Kyoto University showing that chimpanzees outperform humans at spatial number memory. Can you match a chimp?
How It Works
Numbers appear briefly on screen, then are hidden. You must click the positions where the numbers were, in ascending order. Each level adds one more number to remember.
The Research
Professor Tetsuro Matsuzawa's research showed that young chimps have a photographic-like memory for spatial positions. They can recall 9 numbers after seeing them for just 210 milliseconds — faster and more accurately than most adult humans.
Tips
- Focus on the spatial layout, not individual numbers
- Try to snapshot the entire grid at once
- Start from the lowest number position you are most confident about
