Chimpanzee Ayumu routinely scores 19+ in less than 1 second!
🐵 Why Can Chimpanzees Beat Humans?
In 2007, Dr. Tetsuro Matsuzawa at the Primate Research Institute of Kyoto University tested young chimpanzees against university students on this exact task. The chimp (named Ayumu) could recall the positions of 9 numbers shown for just 210 milliseconds with 80% accuracy.
The prevailing evolutionary hypothesis (the Cognitive Trade-Off Hypothesis) suggests that as our human ancestors evolved complex symbolic language and verbal processing, our raw eidetic (photographic) spatial working memory was traded off.
🧠 Strategy Guide
- ✓Scan the screen globally rather than sequentially; build a visual geometric constellation.
- ✓Subvocalize the position pairs (e.g. "top-right, center, bottom-left").
- ✓Act decisively before short-term memory traces degrade.
