Chimpanzees prove they can play rock-paper-scissors

Chimpanzees are capable of understanding the rock-paper-scissors game, Japanese primatologists have discovered.

An experiment at the Primate Research Institute at Kyoto University in Japan, showed the chimpanzee repeatedly choosing the winning hand sign in the game, in exchange for treats.

The study was aimed to investigate whether chimpanzees could learn a transverse patterns by being trained in the rules of rock-paper-scissors game in which paper beats rock, rock beats scissors, and scissors beats paper.

The chimpanzee's performance was comparable to that of a four-year-old child, however, the primate took longer to grasp the game than the children, local media reports.
