Chimp’s gift for numbers

Translating numbers into colors may explain an animal’s apparent memory trick

Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game.

In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares. The player then taps the squares where the numbers had been, in order from 1 to 9. People can do it. But no human competitor has ever completed the game faster or more accurately than Ayumu the chimp.
