How do romaJP6A9028.jpgntic relationships change the self-concept?

When people enter into romantic relationships, they often experience profound changes to the way they think about themselves. Some people experience 'self-expansion' (they add positive traits to their self-concept) as a result of engaging in novel, shared activities with their partner. Other people experience 'self-adulteration' (they add negative traits to their self-concept). For example, a person might start using drugs or alcohol to cope with a partner's abuse.

Along with my students in the Social Relationships Lab at Trinity University, we examine how close relationships affect the self-concept and the consequences that these changes have on overall relationship functioning and quality.  Together with my collaborators, we have developed a two-dimensional model to examine these relationship-induced self-concept changes.
