Resum:	Witnessing rejection against one's group can have similar impacts on psychological distress and aggression as experiencing rejection personally. In this study, we investigated the neural activity patterns of group rejection and whether they resemble those of personal-level rejection. We first identified the neural correlates of social rejection (exclusion based on negative attention) compared with ostracism (exclusion based on lack of social connection) and then compared group-level to personal-level rejection. We employed a novel social exclusion task, "RateME," to induce group and personal rejection and Cyberball to evoke ostracism during fMRI scans. Our results showed that personal rejection increased activity in regions associated with autobiographical memory and self-identity, such as the dorsomedial prefrontal cortex and the lingual gyrus, whereas ostracism engaged areas related to social pain and salience, including the anterior cingulate cortex and the insula. Additionally, group and personal-level rejection elicited similar neural activity patterns, regardless of participants' fusion with the rejected groups. Therefore, group membership seems sufficient for group rejection to trigger self-referential processing pathways similar to those activated by personal rejection. Our findings highlight the overlapping neural mechanisms underlying personal and group-level grievances, which may explain the detrimental effects of group rejection on aggression, extremism, and intergroup conflict.
