Abstract

Previous studies have found that males are more upset over sexual infidelity than females whereas females are more upset over emotional infidelity than males. We hypothesized that such sex differences are explained by explicit sexual imagery by males. The hypothesis was tested in a laboratory using vivid infidelity scenarios and photographs to induce detailed and sexually oriented imagery of a partner's infidelity. In the main experiment, participants included 64 males and 64 females who were currently in committed relationships. The results showed that participants became more upset when they imagined sexual infidelity vividly and realistically than when they did not and there were no significant sex differences in jealousy found when sexual infidelity was imagined in this matter. Overall, our findings suggested that the sex differences in jealousy resulted from males' tendency to imagine sexual infidelity more vividly than females.
