Title Imitation recognition in a captive chimpanzee (Pan troglodytes) Type Journal Article
Year 2005 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 8 Issue 1 Pages (down) 31-36
Keywords Animals; *Awareness; Humans; *Imitative Behavior; Male; Motor Activity; *Movement; Pan troglodytes/*psychology; *Recognition (Psychology)
Abstract This study investigated the ability of a captive chimpanzee (Pan troglodytes) to recognise when he is being imitated. In the experimental condition of test 1a, an experimenter imitated the postures and behaviours of the chimpanzee as they were being displayed. In three control conditions the same experimenter exhibited (1) actions that were contingent on, but different from, the actions of the chimpanzee, (2) actions that were not contingent on, and different from, the actions of the chimpanzee, or (3) no action at all. The chimpanzee showed more “testing” sequences (i.e., systematically varying his actions while oriented to the imitating experimenter) and more repetitive behaviour when he was being imitated, than when he was not. This finding was replicated 4 months later in test 1b. When the experimenter repeated the same actions she displayed in the experimental condition of test 1a back to the chimpanzee in test 2, these actions now did not elicit those same testing sequences or repetitive behaviours. However, a live imitation condition did. Together these results provide the first evidence of imitation recognition in a nonhuman animal.

Title Imitative learning of artificial fruit processing in children (Homo sapiens) and chimpanzees (Pan troglodytes) Type Journal Article
Year 1996 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 110 Issue 1 Pages (down) 3-14
Keywords Animals; Child, Preschool; Discrimination Learning; Female; Food Preferences/*psychology; *Fruit; Humans; *Imitative Behavior; Male; Mental Recall; Pan troglodytes/*psychology; Social Environment
Abstract Observational learning in chimpanzees and young children was investigated using an artificial fruit designed as an analog of natural foraging problems faced by primates. Each of 3 principal components could be removed in 2 alternative ways, demonstration of only one of which was watched by each subject. This permitted subsequent imitation by subjects to be distinguished from stimulus enhancement. Children aged 2-4 years evidenced imitation for 2 components, but also achieved demonstrated outcomes through their own techniques. Chimpanzees relied even more on their own techniques, but they did imitate elements of 1 component of the task. To our knowledge, this is the first experimental evidence of chimpanzee imitation in a functional task designed to simulate foraging behavior hypothesized to be transmitted culturally in the wild.
