When choosing a mate, women are thought to face a trade-off between genetic and parental quality. Recent research suggests that this trade-off is influenced by environmental factors such as pathogen prevalence and resource scarcity, which affect the relative value of genetic and parental quality to offspring fitness. To further investigate these findings, the current study primed 60 women with pathogen prevalence, resource scarcity or an irrelevant threat, before administering a forced trade-off task that assessed mate preferences for traits thought to be indicative of genetic or parental quality. Women primed with pathogen prevalence revealed greater preferences for traits indicative of genetic quality at the expense of traits indicative of parental quality. The reverse was found for women primed with resource scarcity. These findings suggest that environmental factors may directly influence women's mate preferences owing to evolved plasticity, such that mate preferences are flexible in response to environmental factors.
当选择伴侣时，女性被认为面临着遗传和父母质量之间的权衡。最近的研究表明，这种权衡受到环境因素的影响，如病原体流行和资源稀缺，这些因素影响遗传和父母质量对后代适应性的相对价值。为了进一步研究这些发现，本研究用病原体流行、资源稀缺或不相关的威胁来启动 60 名女性，然后让她们完成一项强制权衡任务，评估对被认为代表遗传或父母质量的特征的伴侣偏好。用病原体流行启动的女性表现出对代表遗传质量的特征的更大偏好，而牺牲了代表父母质量的特征。对于用资源稀缺启动的女性则相反。这些发现表明，环境因素可能会直接影响女性的伴侣偏好，因为进化的可塑性，即伴侣偏好可以灵活地响应环境因素。
