摘要:This present study explores the differences between women's and men's responses to (hypothetical) infidelity, and how these responses are influenced by the characteristics of the couple's relationship. 372 subjects completed questionnaires (a) itemising their jealous reaction to a partner´s hypothetical infidelity (emotional or sexual); and (b) the state of their relationship. A survey of 250 women and 122 men revealed that the women reported higher intensity of emotional distress than the men. in regard to both emotional and sexual infidelity. There were no significant differences between men and women in their reports of which infidelity troubled them more: both genders are troubled more by emotional infidelity. We also report the influence that the type of relationship has on the emotions provoked by the infidelity.
