These studies investigate the influence of adults' explicit attention to commonalities of appearance on children's preference for individuals resembling themselves. Three findings emerged: (1) An adult's identification of two dolls' respective similarity to and difference from the child led 3-year-olds to prefer the similar doll (study 1, n = 32). (2) When the adult did not comment on similarity, children age 6 years but not younger preferred physically similar individuals (study 2, n = 68), suggesting that a spontaneous preference for physically similar others does not emerge before school age. (3) Four- but not 3-year-olds generalized an adult's pedagogical cues about similarity, leading them to prefer a self-resembling doll in a new context (study 3, n = 80). These findings collectively suggest that the preference for individuals resembling ourselves develops through a process of internalizing adults' attention to, and messages about, similarities of appearance.
