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.
