Personality and Ostracism: Do Hope, Optimism, and Forgiveness Moderate the Effects of Social Exclusion?

Abstract

This study examined effects of ostracism on psychological well-being and self-control and the roles of the personality traits hope, optimism, and forgiveness as moderators of these effects. Undergraduate students (N=104) were randomly assigned to be included or excluded in a computerized ball-toss game, Cyberball. Facets of psychological well-being examined included belonging and self-esteem. Participants also completed cognitive and physical self-control measures via tracing and handgrip tasks. Ostracized participants experienced less belonging, but there was no significant difference between groups on self-esteem. Ostracized participants persisted for less time on the tracing task. There were no significant differences between groups for performance on the handgrip task. None of the personality traits were found to moderate the effects of ostracism on psychological well-being or self-control. Results are discussed in terms of implications and recommendations for future researchers.
