Too Much of a Good Thing?

Self-discrepancy (SD) theories and self-enhancement (SE) theories have focused primarily on people's motivations to seek either self-consistent or self-enhancing feedback. The two sets of theories, however, also suggest different reactions to the feedback people receive from others. SE theories suggest that people react negatively to evaluations that are more negative than self-evaluations, but positively to evaluations that are more positive. SD theories, like identity control theory, suggest that people react negatively to either under- or overevaluation. We use data from newly married couples over the first three years of marriage to test these different predictions of SD and SE theories. The results indicate strong support for discrepancy theories overall, though an examination of potential moderators suggests that the discrepancy effect is larger when the relationship to the other is stronger. We discuss implications of these results for identity control theory.
