From an evolutionary perspective, phenotypic, social, and environmental factors help to shape the different costs and benefits of pursuing different reproductive strategies (or a mixture of them) from one individual to another. Since men's reproductive success is mainly constrained to women's availability, their mating orientations should be partially calibrated by features that women prefer in a potential partner. For long-term relationships, women prefer traits that signal access to resources, protection skills, and the willingness to share them. Using generalized linear models with laboratory data taken from a Chilean population ( = 197), this study aimed to test whether real and potential resources (measured as self-reported socioeconomic status), protection skills (measured as handgrip strength), and the willingness to provide resources and protection (measured as their disposition toward parenthood) are related to mating orientation in men. Our predictions were: (1) socioeconomic status would be positively associated with long-term and short-term mating orientation but for long-term-oriented individuals, this would be enhanced by having a more favorable parenthood disposition and (2) strength would be positively related to long-term mating orientation in men with higher socioeconomic status and a favorable disposition toward parenthood and it would have a positive and direct association with short-term mating orientation. Our results partially supported the first hypothesis, since men with higher socioeconomic status were more long-term oriented, but parenting disposition did not moderate this effect. Contrary to our expectations, socioeconomic status was not related to short-term mating orientation. Strength appeared not to be significant for long-term mating orientation, even interacting with other traits. However, strength by itself was powerfully linked with a short-term mating orientation. Our results suggest that only some individuals that are attractive for long-term relationships are indeed long-term oriented and may reflect the overall conflict of interests between mating strategies among sexes.
从进化的角度来看,表型、社会和环境因素有助于塑造个体追求不同生殖策略(或多种策略的混合)时所面临的不同成本和收益。由于男性的生殖成功主要受女性可得性的限制,他们的交配取向应部分根据女性在潜在伴侣中所偏好的特征来校准。对于长期关系,女性更喜欢那些表明能够获取资源、具备保护技能以及愿意分享这些资源的特质。本研究使用来自智利人群( = 197)的实验室数据构建广义线性模型,旨在检验实际和潜在资源(以自我报告的社会经济地位衡量)、保护技能(以握力衡量)以及提供资源和保护的意愿(以其为人父母的倾向衡量)是否与男性的交配取向相关。我们的预测是:(1)社会经济地位将与长期和短期交配取向呈正相关,但对于长期取向的个体,更有利的为人父母倾向会增强这种相关性;(2)力量将与社会经济地位较高且为人父母倾向良好的男性的长期交配取向呈正相关,并且与短期交配取向呈正的直接关联。我们的结果部分支持了第一个假设,因为社会经济地位较高的男性更倾向于长期关系,但为人父母的倾向并未调节这种影响。与我们的预期相反,社会经济地位与短期交配取向无关。力量对于长期交配取向似乎并不显著,即使与其他特质相互作用也是如此。然而,力量本身与短期交配取向密切相关。我们的结果表明,只有一些对长期关系有吸引力的个体确实是长期取向的,这可能反映了两性之间交配策略的总体利益冲突。
