Much research has examined how men’s mating strategies change over the development of a relationship consistent with predictions from the Life History Theory. Specifically, research shows that both physiological and behavioural indicators of mating effort decrease once men are mated, and further once they become fathers, unless they remain engaged in mating effort. This switch from mating to parenting effort is sexually selected, and therefore, the corresponding shifts in women should be examined, though to date, women’s short- or long-term mate preferences have been studied as separate entities rather than as a transition in the short to long term. We examined how women’s mate preferences changed over the development of a relationship, to see if they varied consistently with what is known about variation in men’s mating effort. Vignettes detailed four key milestones in the development of a relationship and women rated the importance of the man at each stage displaying indicators of mating or parenting effort. Women increasingly prioritised indicators of parenting effort in men as the relationship developed, consistent with what is known about men’s reduction in mating effort in favour of parenting effort over the development of a relationship. The results support predictions from the Life History Theory and highlight the interacting mutually reinforcing nature of sexually selected behaviours.

一夫一妻制关系发展过程中女性伴侣偏好的变化与男性生活史策略的变化相对应

许多研究已经检验了男人的交配策略在关系发展过程中是如何变化的，这一关系与生命历史理论的预测相吻合。具体来说，研究表明，除非男性继续交配，否则一旦交配，交配努力的生理和行为指标都会下降，一旦成为父亲，交配努力的生理指标和行为指标都会下降。从交配到养育子女的转换是按性别选择的，因此，应该研究女性的相应变化，尽管迄今为止，女性的短期或长期伴侣偏好已作为独立的实体而不是作为短期的过渡进行了研究。长期来看。我们研究了女性伴侣的喜好如何随着关系的发展而变化，以了解它们是否与已知的男性交配努力一致。小插图详细介绍了一段关系发展过程中的四个重要里程碑，妇女在每个阶段都对男人的重要性进行了评估，显示了交配或养育子女的指标。随着关系的发展，妇女越来越优先考虑男人在育儿方面的努力指标，这与已知的关于男人减少交配努力，有利于育儿而不是发展关系的认识相一致。结果支持了生命历史理论的预测，并突出了性行为的相互作用和相互促进的本质。这与已知的关于男人减少交配努力，支持育儿而不是发展关系的情况相一致。结果支持了生命历史理论的预测，并突出了性行为的相互作用和相互促进的本质。这与已知的关于男人减少交配努力，支持育儿而不是发展关系的情况相一致。结果支持了生命历史理论的预测，并突出了性行为的相互作用和相互促进的本质。
