dc.description.abstract
Non-human animals sometimes show marked intraspecific variation in their
cognitive abilities that may reflect variation in external inputs and
experience during the developmental period. We examined variation in
exploration and cognitive performance on a problem-solving task in a large
sample of captive orang-utans (Pongo abelii & P. pygmaeus, N = 103) that had
experienced different rearing and housing conditions during ontogeny,
including human exposure. In addition to measuring exploration and cognitive
performance, we also conducted a set of assays of the subjects’ psychological
orientation, including reactions towards an unfamiliar human, summarized in
the human orientation index (HOI), and towards novel food and objects. Using
generalized linear mixed models we found that the HOI, rather than rearing
background, best predicted both exploration and problem-solving success. Our
results suggest a cascade of processes: human orientation was accompanied by a
change in motivation towards problem-solving, expressed in reduced neophobia
and increased exploration variety, which led to greater experience, and thus
eventually to higher performance in the task. We propose that different
experiences with humans caused individuals to vary in curiosity and
understanding of the physical problem-solving task. We discuss the
implications of these findings for comparative studies of cognitive ability.
