RESUMO
People commit to monogamous relationships with the intent of maintaining sexual exclusivity but often fail to do so. Existing research has focused on individual and relationship characteristics that render relationships more vulnerable to infidelity, paying less attention to strategies that decrease the likelihood of straying. Three experiments investigated the impact of one strategy that might encourage people to enact relationship-protective responses toward alternative partners, perspective-taking. In all studies, participants either adopted the perspective of their partner or not and then evaluated, encountered, or thought about attractive strangers, in Studies 1-3, respectively. Participants' pro-relationship orientation and reactions during these experiences (interest in alternative and current partners, commitment to current relationships, and fantasmatic themes) were recorded. Results showed that perspective-taking decreased sexual and romantic interest in alternatives, while increasing commitment and desire for current partners. These findings suggest that partner perspective-taking discourages engagement in behaviors that may hurt partners and damage the relationship with them.
RESUMO
Research exploring the determinants of infidelity has mainly focused on individual and relationship characteristics that render relationships vulnerable, paying less attention to the external circumstances that increase the likelihood of straying. The present research examined whether online exposure to norms of adultery would affect expressions of desire for alternative mates. In three studies, romantically involved participants were exposed to others' cheating behavior and then thought of or encountered attractive strangers. Their relationship perceptions and reactions during these experiences (fantasmatic themes, expressed interest in alternative partners, and overt flirtation with them in Studies 1-3, respectively) were recorded. Results showed that following exposure to others' cheating behavior, participants were less likely to devalue the attractiveness of alternative partners and to be committed to their relationship. These findings suggest that exposure to adultery norms decreases the awareness of long-term priorities of relationship maintenance, lessening the resistance to the temptation of attractive alternatives.
