Chimpanzees of all ages and all sexes can learn the simple circular relationship between the three different hand signals used in the well-known game rock-paper-scissors. Even though it might take them longer, they are indeed able to learn the game as well as a young child. Jie Gao of Kyoto University in Japan and Peking University in China is lead author of a study in the journal Primates, which is the official journal of the Japan Monkey Centre, and is published by Springer. The research compares the ability of chimpanzees and children to learn the rock-paper-scissors game.
Gao’s research team wanted to find out whether chimpanzees (Pan troglodytes) can grasp extended patterns. They used the rock-paper-scissors game, a popular children’s game in which the hand signal for “paper” always beats “rock,” while “rock” trumps “scissors,” and “scissors” defeats “paper.”
