We often form impressions of others based on superficial information, such as a mere glimpse of their face. Given the opportunity to get to know someone, however, our judgments are allowed to become more individuated. The neural origins of these two types of social judgment remain unknown. We used functional magnetic resonance imaging to dissociate the neural mechanisms underlying superficial and individuated judgments. Given behavioral evidence demonstrating impairments in individuating others outside one's racial group, we additionally examined whether these neural mechanisms are race-selective. Superficial judgments recruited the amygdala. Individuated judgments engaged a cortical network implicated in mentalizing and theory of mind. One component of this mentalizing network showed selectivity to individuated judgments, but exclusively for targets of one's own race. The findings reveal the distinct-and race-selective-neural bases of our everyday superficial and individuated judgments of others. Hum Brain Mapp 3.1:150-159, 2010. (C) 2009 Wiley-Liss, Inc.
