The Story of Ayumu the Chimpanzee

This test is based on a famous experiment conducted at Kyoto University's Primate Research Institute. A young chimpanzee named Ayumu shocked the world by memorizing the positions of numbers 1-9 on a screen in less than 60 milliseconds—faster than the blink of a human eye.
