Prejudice research in social neuroscience has largely relied upon imaging technologies which show that particular 'target' brain areas are activated after presenting prejudice-provoking stimuli. The social neuroscience approach to stereotype formation and prejudice has typically focused on the amygdala and frontal lobe as key areas. fMRI studies have shown that the dorsolateral prefrontal cortex is implicated in the detection of implicit attitudes and the anterior cingulate cortex is associated with their regulation. However, there has been little investigation into the anterior temporal lobes (ATL) despite their involvement in semantic association and social processing. In a recent series of experiments we investigated the role of the ATLs in prejudice by utilising a non-invasive form of brain stimulation - repetitive transcranial magnetic stimulation (rTMS). rTMS has an advantage over imaging techniques because it allows tentative causal inferences to be drawn about a 'target' brain area as it is either stimulated or inhibited and its effect on the behavior in question is observed. The current series of studies show that the ATLs are involved in prejudice and investigate whether this effect is specific to stereotypes or if the effect is generalizable to all categories of concept formation.
