When does performance feedback prompt complementarity in romantic relationships?

Two studies addressed five issues concerning complementarity in romantic relationships and suggest that complementarity deserves a new look. Dating couples (N= 28 couples) and married couples (N= 43). were given performance feedback to assess effects on self and perceived partner relevance. We found that comparison with a partner but not comparison with a stranger prompted complementarity (Study 1). Comparison resulted in complementarity and did not merely change self‐image (Studies 1 and 2). Both outperforming the partner and being outperformed by the partner can prompt complementarity (Study 2). Ceding areas to the partner in response to being outperformed was relatively automatic (Study 2). And, degree of development in the relationship influenced response to comparison‐feedback (Studies 1 and 2). Findings suggest that partners in romantic relationships automatically protect their views of the relationship as a “team” by increasing “perceived complementarity” in response to differential performance feedback.
