Social contact and other-race face processing in the human brain.

The present study investigated the influence social factors upon the neural processing of faces of other races using event-related potentials. A multi-tiered approach was used to identify face-specific stages of processing, to test for effects of race-of-face upon processing at these stages and to evaluate the impact of social contact and individuating experience upon these effects. The results showed that race-of-face has significant effects upon face processing, starting from early perceptual stages of structural encoding, and that social factors may play an important role in mediating these effects.
