Predominance of eyes and surface information for face race categorization

Abstract Faces can be categorized in various ways, for example as male or female or as belonging to a specific biogeographic ancestry (race). Here we tested the importance of the main facial features for race perception. We exchanged inner facial features (eyes, mouth or nose), face contour (everyth...

Here we tested the importance of the main facial features for race perception.

Features were exchanged one at a time, creating for each Asian/Caucasian face pair ten facial variations of the original face pair.
