People regularly encounter tempting alternatives to their relationship partners, and it has been argued that paying attention to desirable alternatives increases the risk of infidelity. However, whether the temptation of noticing attractive alternatives leads to actual infidelity should depend on the ability to resist such temptation. More specifically, taking heed of attractive others should increase the likelihood of infidelity only when people lack self-regulatory ability. One experiment and one longitudinal study of newlyweds both demonstrated that the implications of attending to attractive alternatives for infidelity depended on participants' self-regulatory ability to resist such temptations. Specifically, the tendency to notice attractive alternatives was associated with greater infidelity among those with poorer self-regulatory ability, but not among those with greater self-regulatory ability. These results further understanding about how people can maintain and protect their relationships in the face of temptation.
Maintaining sexual satisfaction is a critical, yet challenging, aspect of most romantic relationships. Although prior research has established that sexual communal strength (SCS)—i.e., the extent to which people are motivated to be responsive to their partner’s sexual needs—benefits romantic relationships, research has yet to identify factors that promote SCS. We predicted that gratitude would increase SCS because gratitude motivates partners to maintain close relationships. These predictions were supported in three studies with cross-sectional, longitudinal, and experimental methods. Specifically, experiencing and receiving expressions of gratitude were associated with greater SCS. These studies are the first to investigate the benefits of gratitude in the sexual domain and identify factors that promote SCS. Together, these results have important implications for relationship and sexual satisfaction in romantic relationships.
Societal changes over recent decades have drastically transformed the frequency and manner in which people are exposed to attractive alternative relationship partners, arguably resulting in such alternatives posing a greater threat to committed relationships now than ever before. Yet despite a growing need for novel research on attractive alternatives, research on this topic has failed to account for such changes and thus is growing stagnant. Specifically, although interdependence perspectives and supporting research have consistently and robustly demonstrated that (a) attractive alternatives threaten committed relationships and (b) committed partners protect their relationships by devaluing such alternatives, research has yet to examine how the changing nature of attractive alternatives might affect these processes.To this end, the present article first reviews foundational theory and research that guided the study of attractive alternatives and then highlights how recent societal changes (e.g., technology that increases access to attractive alternatives, increasingly diverse relationship types, the emerging desire to remain single) diverge from this research and thus warrant new directions. We encourage researchers to expand how they study attractive alternatives and to ultimately reignite research on this increasingly important topic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
