Don’t challenge a chimpanzee named Ayumu to a number memory game!! The game goes like this: player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares. Player taps the squares where the numbers had been, in order, from 1 to 9. People can do it. But no human has ever completed the game faster or more accurately than Ayumu the chimp!
Could this be synesthesia at work?
What do you think??
