Are you smarter than a chimpanzee? Test your extraordinary spatial memory limits under extreme pressure.
This test is based on a famous study showing that chimpanzees can recall number grids far faster than humans.
Humans trade off this extreme spatial memory for language processing capacity.
Test your brain's ability to 'snapshot' a scene and retrieve it under pressure.
Push your short-term buffer to its absolute mechanical limits.
One mistake ends the trial—requiring total attentional immersion.
The Chimp Test is a benchmark for **spatial working memory**. It replicates famous primate research conducted at Kyoto University, measuring your ability to encode multiple locations in a fraction of a second and recall them in sequence without visual labels.
In primate studies, young chimpanzees (specifically a chimp named Ayumu) consistently outperformed adult humans by memorizing the location of 9 digits in less than 500ms. Anthropologists suggest the **Cognitive Tradeoff Hypothesis**: as humans evolved complex language and symbolic thinking, we sacrificed the immediate "eidetic" (photographic) spatial memory that remains vital for non-human primates in the wild.
Spatial Chunking: Don't try to remember digits. Try to remember the "shape" formed by the numbers 1, 2, 3, and 4 as a single object.
Pathway Visualization: Draw a mental "lightning bolt" connecting the first five numbers. This converts sequential data into a single spatial map.
Peripheral Gaze: Keep your eyes centered on the grid rather than darting between blocks. Your peripheral vision is better at capturing global spatial layout.
Spatial memory is a key component of **Fluid Intelligence (Gf)**. It is essential for navigation, architectural planning, and complex problem-solving where multiple variables must be held in the mind simultaneously.
The Chimp Test measures your visuospatial working memory — the ability to remember the positions and order of numbered squares after they disappear. This test is inspired by Ayumu, a chimpanzee at Kyoto University who outperformed humans at this task in a landmark 2007 study. It tests your ability to quickly encode spatial information into short-term memory.
Numbers appear on a grid. After you click the first number, all others are hidden. You must click them in ascending order from memory. Each correct sequence increases the difficulty by one number. You get 3 strikes (wrong clicks) before the test ends. The test starts at 4 numbers. Your score is the highest level reached.
The average human scores 7 on the Chimp Test (remembering 7 numbers in sequence). Scores of 9+ are excellent and place you in the top 10%. Young chimpanzees in research settings consistently score 9-10. Very few humans can match the performance of trained primates on this specific task.
This test is based on Tetsuro Matsuzawa's research at the Primate Research Institute, Kyoto University. In his studies, young chimpanzees consistently outperformed adult humans, memorizing the positions of 9 numerals in under 200ms. The difference is attributed to an 'eidetic-like' photographic short-term memory that humans may have traded for language processing during evolution. The task specifically measures the visuospatial sketchpad component of working memory.
Use spatial patterns — look for geometric shapes formed by the numbers rather than memorizing individual positions.
Practice rapid encoding — try to photograph the entire grid in one glance rather than scanning sequentially.
Focus on the first glimpse — your initial impression captures the most spatial information before conscious processing interferes.
Start from the edges — peripheral numbers are harder to remember, so encode those first.
Stay calm under pressure — anxiety reduces working memory capacity by up to 30%.
Yes. In Tetsuro Matsuzawa's 2007 study at Kyoto University, young chimpanzees consistently outperformed university students. Chimps like Ayumu can memorize 9 numbers in 60ms — faster than any human tested. This suggests primates have a photographic short-term memory that humans may have lost during the evolution of language.
The average human score is about 7. A score of 9 or above is excellent and places you in the top 10%. Scores of 11+ are rare and suggest exceptional visuospatial working memory.
