Evidence of model based transmission bias in captive chimpanzees: initial tool choice matches proficient groupmate

2016-03-01

Abstract excerpt

Social learning theories predict biased transmission dictating what and whom is copied. We presented a novel tool-use task to six groups of captive chimpanzees ( Pan troglodytes ) to investigate a model proficiency bias. The study included six groups totalling 54 chimpanzees (24 males) housed in six social groups at the KCCMR, University of Texas, U.S.A. Subjects were aged 12- to 43-years-old ( M = 24.5 years,...
