Race categorization in noise
People are typically faster to categorize the race of a face if it belongs to a race different from their own. This Other Race Categorization Advantage (ORCA) is thought to reflect an enhanced sensitivity to the visual race signals of other race faces, leading to faster response times. The current s...

People are typically faster to categorize the race of a face if it belongs to a race different from their own.
