Face Processing In Humans And New World Monkeys: The Influence Of Experiential And Ecological Factors. Animal Cognition, Julie J. Neiworth, Janice M. Hassett, Cara J. Sylvester

This study tests whether the face-processing sys- tem of humans and a nonhuman primate species share char- acteristics that would allow for early and quick processing of socially salient stimuli: a sensitivity toward conspecific faces, a sensitivity toward highly practiced face stimuli, and an ability to generalize changes in the face that do not sug- gest a new identity, such as a face differently oriented. The look rates by adult tamarins and humans toward conspecific and other primate faces were examined to determine if these characteristics are shared. A visual paired comparison (VPC) task presented subjects with either a human …
