Nurtured chimps rake it in

uary chimpanzees chose randomly between the two hybrid tools. The captive laboratory chimpanzees failed both tests, as demonstrated in previously published work (2).

According to Dr. Sarah Boysen, who led the study, “We think our findings mean that the conditions under which chimpanzees are raised, housed, and maintained have long-term effects on their cognitive development, and offer direct comparisons with early experience, issues of attachment, and preschool education for human infants and children,”

The authors conclude that the differences in performance between the three groups are directly attributable to the significant effect of level of enculturation. They add that “enculturated chimpanzees may be better at learning within a highly social, interactive context because they have heightened attention to the actions of others.”
