Abstract

The Reproductive Compensation (RC) hypothesis and the Differential Allocation (DA) hypothesis predict that parents who mate under constraint will either increase or decrease, respectively, their reproductive effort and investment in offspring. One possible type of mate choice constraint in humans is arranged marriage in which parents or others choose mates. To test the RC and DA hypotheses in humans, we examine whether there are differences in parental investment between women in arranged marriages and those in self-choice marriages using data from the Indonesian Family Life Survey (n = 8393). Marriage type does not significantly correlate with parental investment except for fertility outcomes where women in self-choice marriages had more live births, living children, and greater marital fertility than woman in arranged marriages. Our findings better support the DA hypothesis than the RC hypothesis. We conclude that, like many other species, free mate choice is associated with increased reproductive success in this sample of humans.

母亲在包办婚姻和自我选择婚姻中的投资:对人类生殖补偿和差异分配假说的检验

生殖补偿假说(Reproductive Compensation hypothesis)和差异分配假说(Differential Allocation hypothesis)预测，在约束条件下交配的亲本分别会增加或减少对后代的生殖努力和投入。人类择偶约束的一种可能类型是包办婚姻，即父母或他人选择配偶。为了在人类中检验RC和DA假设，我们使用印度尼西亚家庭生活调查(n = 8393)的数据，研究了包办婚姻和自主选择婚姻的女性在亲代投资方面是否存在差异。除了生育结果外，婚姻类型与亲代投资没有显著相关，在生育结果中，自我选择婚姻的女性比包办婚姻的女性有更多的活产、活产子女和更高的婚姻生育率。我们的研究结果更支持DA假说而不是RC假说。我们的结论是，像许多其他物种一样，在这个人类样本中，自由的配偶选择与繁殖成功率的提高有关。

期刊介绍： Evolution and Human Behavior is an interdisciplinary journal, presenting research reports and theory in which evolutionary perspectives are brought to bear on the study of human behavior. It is primarily a scientific journal, but submissions from scholars in the humanities are also encouraged. Papers reporting on theoretical and empirical work on other species will be welcome if their relevance to the human animal is apparent.
