Social rejection elicits distress through the brain’s alarm system, the dorsal anterior cingulate cortex (dACC). The distress of rejection facilitates subsequent inclusion. As a result, traits that blunt this dACC response to social rejection might then threaten group membership, leading to further subsequent rejection. Alexithymia, the inability to identify and describe...
Social rejection often increases aggression, but the neural mechanisms underlying this effect remain unclear. This experiment tested whether neural activity in the dorsal anterior cingulate cortex (dACC) and anterior insula in response to social rejection predicted greater subsequent aggression. Additionally, it tested whether executive functioning moderated this relationship...
