تفاوتهای جنسی در حسادت انسان: مطالعه هماهنگ انتخاب اجباری، مقیاس امتیاز مستمر و پاسخ های فیزیولوژیک در افراد مشابه

Previous investigators have confirmed the evolutionary hypothesis that the sexes differ in their responses to sexual vs. emotional infidelity and have taken their results as suggesting the existence of a mechanism that regulates the perceptions of threat, the emotional responses, and the physiological reactions that constitute jealousy. This notion implies that these three categories of response should occur systematically in the same group of subjects. However, no study has been done to confirm this implication. This study is the first to demonstrate the traditional findings concerning these three categories of response on the same group of subjects. Overall, the results of this investigation are consistent with the core evolutionary hypothesis of sex differences in human jealousy.

One of the most widely disseminated conclusions of evolutionary psychological research is that male and female jealousy is inspired by different threats Buss et al., 1999, Buunk et al., 1996 and Symons, 1979. While male jealousy is more likely to be inspired by threats of sexual infidelity, female jealousy is more likely to be inspired by threats of emotional infidelity Buss et al., 1992, Buunk et al., 1996 and Wiederman & Allgeier, 1993. Such sex differences have been observed in the United States Buss et al., 1992, Buunk et al., 1996, DeSteno & Salovey, 1996 and Harris & Christenfeld, 1996, the Netherlands, Germany, Korea, Japan (Buunk et al., 1996), and Sweden (Wiederman & Kendall, 1999). According to Buss (1994), sex differences in the eliciting factors of human jealousy are probably a human universal.
