In this article, we present what has been learned so far from the social neuroscience of prejudice. In the following sections, we describe research on how people perceive groups and categorize their members, how prejudice is learned and represented in the mind, how it relates to judgment, perception, emotion, and behavior, and how its effects may be regulated. Rather than provide an exhaustive list of findings, we take a step back and ask: what has the neuroscience approach revealed, so far, about the psychology of prejudice? In each section, we discuss key social neuroscience findings, consider interpretational challenges and connections with the behavioral literature, and highlight how they advance psychological theories of prejudice.
