What did your review of the neuroscience literature show?

My colleagues and I found that there’s a network of brain regions that is consistently activated in neuroimaging studies of race processing. This network overlaps with the circuits involved in decision-making and emotion regulation, and includes the amygdala, fusiform face area (FFA), anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC).


How does the neuroscience fit with the psychological model?

Activity in the FFA isn’t surprising, because all of these studies use photos of faces. The amygdala is involved in emotions, and might be linked to the automatic evaluations we make when we see people from other racial groups. We think that the ACC and DLPFC are involved in more complex functions. People tend to show unintentional indications of race bias, even when they are motivated to be non-prejudiced, so the ACC may be involved in detecting these conflicts. You can have an implicit bias and choose not to act on it, and the DLPFC may be trying to regulate the emotional responses that conflict with our egalitarian goals and beliefs.
