Chimps equal 4-year-old humans in rock-paper-scissors: Study
A China-Japan research collaboration has found chimpanzees are as good as average 4-year-old humans in learning the rules of rock-paper-scissors game in which hand configurations of 'paper' beat 'rock', 'rock' beat 'scissors', and 'scissors' beat 'paper'. Five of the seven chimpanzees completed training after a mean of 307 sessions while children aged 35â71 months needed the same number of trials.
