Using data collected from people with at least one brother and one sister, and consistent with an evolutionary perspective, we find that older men and women (a) are more upset by a brother's partner's sexual infidelity than by her emotional infidelity and (b) are more upset by a sister's partner's emotional infidelity than by his sexual infidelity. There were no effects of participant sex or sex of in-law on upset over a sibling's partner's infidelities, but there was an effect of participant sex on reports of upset over one's own partner's infidelities. The results suggest that the key variable among older participants is the sex of the sibling or, correspondingly, the sex of the sibling's partner, as predicted from an evolutionary analysis of reproductive costs, and not the sex of the participant, as predicted from a socialization perspective. Discussion offers directions for future work on jealousy.
利用从至少有一个兄弟和一个姐妹的人那里收集的数据，并与进化观点相一致，我们发现，年长的男性和女性：(a) 对兄弟伴侣的性不忠比情感不忠更感到不安；(b) 对姐妹伴侣的情感不忠比性不忠更感到不安。参与者的性别或姻亲的性别对因兄弟姐妹伴侣不忠而产生的不安没有影响，但参与者的性别对因自己伴侣不忠而产生的不安报告有影响。结果表明，如从生殖成本的进化分析所预测的那样，年长参与者中的关键变量是兄弟姐妹的性别，或者相应地，是兄弟姐妹伴侣的性别，而不是如从社会化角度所预测的参与者的性别。讨论为未来关于嫉妒的研究提供了方向。
