Abstract: | Four rhesus monkeys, Macaca mulatta, were trained on average in 428 trials to indicate by pointing with the extended arm which of two food boxes contained a food reward. They then rapidly learnt to select the box indicated (by pointing) by a human experimenter, making only 11-17 errors in 100 trials; whereas animals previously not trained to point performed at chance. It is concluded that rhesus monkeys, like chimpanzees, Pan troglodytes, can be trained to point, whereas pigmy chimpanzees, Pan paniscus, may point naturally in the way a human child does. |
