Two studies examined the effectiveness of self- and group-affirmation in reducing the aversiveness of ingroup and outgroup ostracism. It was hypothesized that in the case of ingroup ostracism, self-affirmation (but not group-affirmation) would be more effective in buffering against negative reactions than no-affirmation, whereas in the case of outgroup ostracism, group-affirmation (but not self-affirmation) would be more effective than no-affirmation. Both studies employed a 3 (affirmation: self vs. group vs. no) × 2 (ostracism: ingroup vs. outgroup) between-participants design. After completing a self-affirming, group-affirming, or non-affirming writing task, undergraduates were ostracized by either ingroup or outgroup members in a three-person Cyberball game. Participants in Study 1 (strong ostracism) and Study 2 (moderate ostracism) received the ball on 6.7% and 16.7% out of thirty tosses, respectively. In Study 1, participants reported uniformly high levels of aversiveness and negative emotions across the six conditions. In Study 2, in the ingroup ostracism condition, self-affirmed participants, but not group-affirmed participants, reported significantly lower aversiveness and less negative emotion than did non-affirmed participants. In the outgroup ostracism condition, neither self- nor group-affirmation reduced negative responses relative to no affirmation. Implications and suggestions for future studies are discussed.
