It Just Looks the Same: An Evolutionary Psychological Account of Differences in Racial Cognition Among Infants and Older Humans

Abstract

Forms of racial cognition begin early: from about 3 months onwards, many human infants prefer to look at own-race faces over other-race faces. What is not yet fully clear is what the psychological mechanisms are that underlie racial thoughts at this early age, and why these mechanisms evolved. In this paper, we propose answers to these questions. Specifically, we use recent experimental data and evolutionary biological insights to argue that early racial cognition is simply the result of a "facial familiarity mechanism": a mental structure that leads infants to attend to faces that look similar to familiar faces, and which probably has evolved to track potential caregivers. We further argue that this account can be combined with the major existing treatments of the evolution of racial cognition, which apply to (near-) adult humans. The result is a heterogeneous picture of racial thought, according to which early and later racial cognition result from very different psychological mechanisms.
