本研究探讨了单一性伙伴(n = 222)、两个以上性伙伴(n = 145)与无性伙伴(n = 106)三组低收入女性的长期配偶偏好、人生阅历、生活史特质与个人特征的关系。研究结果显示三组女性的配偶偏好趋于一致,繁衍策略的组别差异与人生阅历和所处环境具有较高相关,三组女性并不偏好特定类型的配偶。路径分析显示首次生育年龄直接预测配偶数量,受教育水平和初次性交时间对配偶数量与首次生育年龄之间的关系具有显著调节作用;女儿与父亲相处的时间可以预测初次性交年龄。研究结果显示父亲投资影响青少年性行为发展的时间表,人类繁衍的长期进化是性行为变化的根源。
This study examined long-term spouse preferences, life experiences, life history traits and personal characteristics of single-sex partners (n = 222), two or more partners with sexual partners (n = 145) Relationship. The results show that the three groups of women’s spouse preferences tend to be consistent, reproductive strategy group differences and life experience and environment are highly correlated, three groups of women do not prefer a particular type of spouse. Path analysis showed that the first birth age directly predicted the number of spouses, education levels and first-time sexual intercourse had a significant regulatory effect on the relationship between the number of spouses and the first-time childbearing age. The time spent by daughters and fathers could predict the first sexual intercourse. The results show that the father’s investment in adolescent sexual behavior development schedule, the long-term evolution of human reproduction is the source of sexual behavior changes.
