Chimp Test
01 /How to Play
- Click 'Begin Protocol' to start.
- Numbers will appear briefly at random positions on the grid.
- After they disappear, click the squares in ascending numerical order (1, 2, 3...).
- Each correct round adds one more number.
- One wrong click ends the test — your score is the highest level completed.
02 /The Science
This test is inspired by research conducted at the Primate Research Institute of Kyoto University, where chimpanzees demonstrated superior performance to humans in sequential numerical working memory tasks. The study, led by Dr. Tetsuro Matsuzawa, showed that young chimps could memorize and reproduce the positions of numbers 1–9 after a 210ms exposure — faster and more accurately than adult humans. The human disadvantage is thought to stem from our heavy reliance on language-based processing, which introduces interference. This test engages the same visuospatial sketchpad and sequential processing circuits, with performance highly correlated with fluid intelligence scores.

03 /Pro Tips
- Don't try to read the numbers — scan the entire grid and build a spatial map of all positions simultaneously.
- During the flash, fixate on the center of the grid rather than tracking individual numbers.
- Click in a smooth spatial arc rather than jumping randomly — motor memory reduces cognitive load.
- The key insight: process positions, not values. Your brain is faster at spatial than numerical recall.
- Practice the lower levels until they feel automatic — this frees up working memory for the higher numbers.
