title: Mapping the time course of other-race face classification advantage: a cross-race ERP study.
abstract: The current study investigated the time course of the other-race advantage (ORA) in the subordinate classification of faces by race. A significant ORA was found on RTs for both races. The ERP data showed that the categorization processes follow basic level classification of physiognomic stimuli, which is not influenced by the stimulus race. The most conspicuous difference between own-race and other-race faces was found in the modulation of the amplitude of the P3. Since the amplitude of the P3 is sensitive primarily to the perceptual demands of a task, these data suggest that the delay of the own-race classification is caused by an own-race specific process that precedes or interferes with the subordinate classification.
