The Emerging Integration of Close Relationships Research and Evolutionary Psychology

Abstract

Romantic relationships are a central focus of scientific inquiry within two psychological literatures—those on close relationships and evolutionary psychology—yet attempts to bridge these topics have been surprisingly rare. Recently, several lines of research have begun drawing from the methodological and theoretical traditions of each literature to inform the other. For example, evolutionary perspectives have recently made important contributions to the study of romantic relationships by highlighting the positive effects of negative emotions (e.g., jealousy) and the potentially negative implications of hormonal contraception use. In addition, the emphasis in the close relationships literature on relationship development over time has begun to refine scholars’ understanding of the ubiquitous evolutionary psychological distinction between short-term and long-term relationships as well as the classic concept of mate value. These lines of work exemplify how the edges of two intersecting literatures can generate intellectual sparks that ignite both fields.
