Research on some non-human species suggests that an abundance of reproductively viable males relative to females can increase female choosiness and preferences for longer-term mating and resource investment by males. Yet little research has explored the potential influence of mate availability upon women’s preferences for signals of men’s commitment and resource provisioning. Using an experimental mate availability priming paradigm, the present study examined whether women ( N = 205) primed with either mate scarcity or abundance would differ in their expectations for engagement ring size and cost. Results demonstrated that women who were primed with the belief that good-quality mates are abundant in the population reported expecting a statistically-significantly larger and more expensive engagement ring relative to women primed with mate scarcity. Results suggest that women flexibly attune their expectations for signals of men’s investment based, in part, upon their perception of the availability of viable mates.

诱导伴侣的丰满提高了女性对订婚戒指尺寸和成本的期望

对某些非人类物种的研究表明，相对于雌性而言，大量具有生殖能力的雄性可增加雌性选择，并增加雄性对长期交配和资源投资的偏好。然而，很少有研究探讨伴侣的可获得性对女性偏爱男性承诺和资源供应信号的偏好的潜在影响。本研究使用实验性的配偶可利用性启动范例，研究了因配偶稀少或丰盛而被配发的女性（N = 205）在订婚戒指尺寸和成本上的期望是否会有所不同。结果表明，那些以优质配偶为生的人认为，与那些缺乏配偶的女性相比，期望有一个统计学上显着更大，更昂贵的订婚戒指。
