The Power to Flirt: Power within Romantic Relationships and Its Contribution to Expressions of Extradyadic Desire.

Power in non-romantic contexts makes people confident in their ability to attract potential partners, increasing their mating motivation and the likelihood of acting on this motivation. Four studies investigated whether perceptions of power within romantic relationships would also activate mating goals, intensifying desires for alternative partners. In Studies 1 and 2, participants underwent power manipulation and then described a sexual fantasy or evaluated photos of attractive strangers. Studies 3 and 4 used face-to-face interaction and daily experiences methods to examine the mechanisms underlying the link between power and extradyadic desires. Overall, high perceived relationship power was associated with increased interest in alternatives. Perceived relative mate value explained this association, suggesting that what determines whether power elicits extradyadic interest is not power perceptions alone but rather the feeling of having a higher mate value than one's partner that accompanies elevated power and affects whether high-power individuals will prioritize their own needs in ways that may hurt their partners.

When Your Partner is Being Flirted With: The Impact of Unsolicited Attention on Perceived Partner Desirability and Mate Retention Efforts.

When searching for a partner, people often rely on social cues to determine partners' suitability, finding those who attract attention from others particularly appealing. While people continue to evaluate their partners beyond relationship initiation, existing research has predominantly concentrated on the effects of observing others' choices during the stage of partner selection, neglecting to consider whether viewing others' attention toward current partners yields similar effects or instead elicits defensive devaluation. In three experiments, we exposed Israeli participants to situations where their partners received unsolicited flirtatious advances, utilizing visualization, virtual reality, and recall techniques. Participants then rated their desire for their partner and mate retention efforts. Results indicated that attention to partners led to decreased desire for them, subsequently predicting reduced relationship investment. These findings suggest that witnessing current partners receiving attention holds a different meaning than observing potential partners in a similar situation, making salient the risk of losing the partner.

Put Me in Your Shoes: Does Perspective-Taking Inoculate Against the Appeal of Alternative Partners?

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.

Is Infidelity Contagious? Online Exposure to Norms of Adultery and Its Effect on Expressions of Desire for Current and Alternative Partners.

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.
