Abstract

Faces of one's own race and of other races are thought to be located in different regions of face space (Valentine, 1991). Here we investigated whether faces of different races (Caucasian and Chinese faces) have dissociable neural coding and distinct norms. We used adaptation techniques to alter perceptions of normality (aftereffects) for faces. Caucasian and Chinese participants adapted to distorted faces of one race (e.g., Chinese contracted faces-Experiment 1), or oppositely distorted faces of both races (e.g., Chinese contracted and Caucasian expanded faces-Experiment 2). We then tested for aftereffects in Chinese and Caucasian test faces. In Experiment 1 aftereffects were reduced when a change in race between the adapt faces and test faces occurred. In Experiment 2 aftereffects occurred in opposite directions for the two races. These results demonstrate that dissociable neural populations code faces of different races and suggest the existence of race-specific face norms.
