title: An assessment of generalization of imitation in two enculturated orangutans (Pongo pygmaeus).
abstract: Deferred imitation of object-related actions and generalization of imitation to similar but not identical tasks were assessed in two human-reared (enculturated) orangutans (Pongo pygmaeus). Each ape displayed low levels of deferred imitation but did not provide evidence of generalization of imitation. Results suggest that enculturated orangutans may not possess social-cognitive abilities similar to that which enculturated chimpanzees are assumed to possess.
