Self-expansion motivation improves cross-group interactions and enhances self-growth

Rather than seeing outgroup members as targets of fear, conflict, or even tolerance, the self-expansion model proposes that outgroup members might be seen as attractive opportunities for self-growth. The current study utilizes an experimental manipulation to raise (or lower) self-expansion motivation prior to a positive interaction with a stranger from a different ethnic group. The results show that priming high self-expansion motivation leads to higher quality interactions, greater interpersonal closeness, greater feelings of self-growth, and higher feelings of self-efficacy. In addition, these outcomes show patterns of mediation consistent with the predictions of self-expansion theory. These findings point to a potentially valuable tool for improving the quality of cross-group contact experiences. More broadly, they focus attention on the genuinely positive functions that relationships with outgroup members can have for the self.
