Studies have shown chimpanzees can learn to perform tasks by watching live or videotaped demonstrators. The present study assessed whether female chimpanzees exposed to a videotaped demonstrator would learn a husbandry-related task, urinating into a receptacle on cue, faster than those without this experience. Nine adult chimpanzees were assigned to either control or experimental conditions. Experimental subjects were shown a “relevant” videotape of a chimpanzee urinating into a receptacle and immediately being given positive reinforcement. Control subjects were shown an “irrelevant” videotape of a chimpanzee performing a different task and immediately being given positive reinforcement. Subjects were exposed to the videotape 17 times. After each viewing, a trainer, blind to the experimental condition, conducted a 15-minute training session with the subject. During these 17 training sessions, 100% of the animals watching the relevant videotape urinated into the receptacle, while only 50% of the animals watching the irrelevant videotape met this training goal. While not significant with our small sample size [X2(1)=3.2, P=0.07], this outcome provides evidence that chimpanzees can use information from videotaped demonstrations and apply it to a training task. This study is an example of capitalizing on the cognitive abilities of chimpanzees to enhance chimpanzee behavioral management.
