Excluded from humanity: The dehumanizing effects of social ostracism

Humans have a fundamental need to form and maintain relationships. Social exclusion frustrates this need and has devastating psychological effects. The current research examines the relationship between social exclusion and the experience of dehumanization from the target's perspective. When people were ostracized they judged themselves and those who ostracized them as less human (Studies 1 and 2), and believed they were viewed as less human by the perpetrators (Study 2). In both studies, essential 'human nature' was the dimension of humanness most sensitive to social exclusion.
