Preadolescents' recognition of faces of unfamiliar peers: the effect of attractiveness of faces

The authors examined preadolescents' ability to recognize faces of unfamiliar peers according to their attractiveness. They hypothesized that highly attractive faces would be less accurately recognized than moderately attractive faces because the former are more typical. In Experiment 1, 106 participants (M age = 10 years) were asked to recognize faces of unknown peers who varied in gender and attractiveness (high- vs. medium-attractiveness). Results showed that attractiveness enhanced the accuracy of recognition for boys' faces and impaired recognition of girls' faces. The same interaction was found in Experiment 2, in which 92 participants (M age = 12 years) were tested for their recognition of another set of faces of unfamiliar peers. The authors conducted Experiment 3 to examine whether the reason for that interaction is that high- and medium-attractive girls' faces differ more in typicality than do boys' faces. The effect size of attractiveness on typicality was similar for boys' and girls' faces. The overall results are discussed with reference to the development of face encoding and biological gender differences with respect to the typicality of faces during preadolescence.
