It will (never) stop hurting: Do repeated or chronic experiences of exclusion lead to hyper- or hyposensitive...

Unlike one-time lab manipulations of exclusion, in real life, many people experience exclusion, from others and from groups, over extended periods, raising the question of whether individuals could, over time, develop hypo- or hypersensitive responses to chronic exclusion. In Study 1, we subjected participants to repeated experiences of inclusion or exclusion (three Cyberball games, time lag of three days, N = 194; 659 observations). We find that repeatedly excluded individuals become hypersensitive to inclusion, but not to exclusion. Study 2 (N = 183) tested whether individuals with chronic experiences of real-world exclusion show hypo- or hypersensitive responses to a novel episode of exclusion. In line with Study 1, exclusion hurt to the same extent regardless of baseline levels of chronic exclusion in daily life. However, chronically excluded individuals show more psychological distress in general. We discuss theoretical and practical implications for dealing with chronically excluded individuals and groups.
