Imitation in Free-Ranging Rehabilitant Orangutans (Pongo pygmaeus)

摘要: ~~~~~~7$;~ We made an observational study of spontaneous imitation in orangutans (Pongo pygmaeus). Previous studies may have underestimated great apes' imitative capacities by studying subjects under inhibiting conditions. used living enriched environments, namely, rehabili­ tation. collected a sample imitations and analyzed the most complex incidents for likelihood that true imitation, learning new actions observing rather than doing, was involved their acquisition. From 395 hr observation other reports on 26 orangutans, we identified 354 imitation. Of these, 54 were difficult to explain forms based associative processes grounded experiential alone; they were, however, congruent with acquisition include These findings suggest be capable point critical eliciting factors. Imitation, general sense replicating whatever mechanism behavior inspired model, has been focus
