Measuring psychological similarity of faces

Abstract

Recognition memory for unfamiliar other-race faces is poorer than for unfamiliar own-race faces. This observation would be understandable if the within group homogeneity of Japanese faces was greater than white American faces. In a test of this question, both decision time and correctness of same-different judgments offered no evidence to support the hypothesis of differential within group homogeneity. © 1976, The Psychonomic Society, Inc..
