Disruption of Performance of a Lab-Born Orangutan after Introduction of Irrelevant Foreground Cues
No full text Discrimination performance of the three great ape genera has previously been shown to be differentially influenced by the introduction of irrelevant foreground cues, with accuracy of performance of orangutans significantly more disrupted than chimpanzees or gorillas. This disruption may be species-related to how arboreal of terrestrial the subjects would be in their natural habitat. The tendency of the orangutan toward disruption of performance following the introduction of visual foreground cues is not dependent upon an early arboreal environment, because the performance of the lab-born orangutan tested in similar conditions in the present study was commensurate with the performance of previously tested wild-born orangutans. </jats:p
