中文摘要 | 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。 |
英文摘要 | We contrasted the long-term mate preferences, reported developmental experiences, life history traits, and current personal traits of low-income women who reproduced with a single man (n = 222), two or more men (n = 145), or had not yet reproduced (n = 106). The mate preferences of the three groups were more similar than different, suggesting that group differences in reproductive strategy may be more strongly related to developmental experiences and current circumstances than to explicit preferences for one type of reproductive partner or another. Path analytic models revealed that the only direct predictor of number of reproductive mates was age of first reproduction, which in turn was predicted by level of education and age of first sexual intercourse. Age of first intercourse, in turn, was predicted by time spent with father. The pattern suggests paternal investment influences timing of adolescent sexual activity, and timing of this activity can set in motion a long-term reproductive trajectory. |
