When do opposites attract? Interpersonal complementarity versus similarity

Two experiments examined whether interpersonal complementarity or similarity influences people's satisfaction with dyadic interactions. Participants in complementary partnerships (submissive people with dominant partners, dominant people with submissive partners) reported more satisfaction than did those with similar partners. In Study 1 complementarity referred to the match between the participants' self-reported interpersonal style (dominant or submissive) and the role enacted by a confederate (dominant or submissive). Tn Study 2 participants interacted in pairs, and complementarity referred to the match between one participant's interpersonal goals and the other's overt behavior Participants whose goals were complemented by their partners' behavior were more satisfied with the interaction than those whose goals were not. In both studies satisfied participants perceived their partners as similar to themselves.
