تکامل، جنسیت و حسادت: بررسی با نمونه از سوئد

When asked to choose which would be most upsetting, a mate’s sexual or emotional infidelity, past research has demonstrated that men are more likely than women to choose sexual infidelity, whereas women are more likely than men to choose emotional infidelity. Explanation of this sex difference has been controversial. In the current study we attempted to replicate previous research by examining a sample of college students in Sweden. In doing so, we also investigated the “double-shot” explanation. In the current study, the majority of men chose the sexual infidelity scenario as most upsetting, whereas the majority of women chose the emotional infidelity scenario as most upsetting. Contrary to the double-shot explanation, choice of scenario was unrelated to attitudes regarding whether the other sex was capable of satisfying sexual relations outside of a love relationship.

More than 50 years ago Alfred Kinsey noted that men appear to be more concerned about the sexual aspects of a mate’s potential infidelity, whereas women appear to be more concerned about lost attention, emotional investment, and love from their mate (Kinsey et al. 1948: 592). More recently, writers have attempted to explain the evolutionary origins of these apparent sex differences Daly and Wilson 1983, Daly et al. 1982 and Wilson and Daly 1992. Specifically, sex differences in confidence of parenthood and the roles members of each sex play in childrearing have been used to explain why men and women can be expected to be differentially sensitive to cues of sexual versus emotional infidelity, respectively Buss et al. 1992, Symons 1979 and Wiederman and Allgeier 1993. Has recent empirical research supported such a claim?
