ABSTRACT

Life history theory – which considers the influence of environmental factors that occur over the course of an organism’s life in determining patterns of development and behavior – has been used to provide insight into the cause and interpretation of a wide variety of individual differences traits. Recent research has added individual differences in mate value to this list, such that high mate value has been correlated with a slow life history strategy. The current research replicated and further explored this relationship across two studies. Consistent with previous research, Study 1 demonstrated a moderate correlation between life-history strategy and a general assessment of self-perceived mate value. Study 2 expanded this investigation to include a multifactor assessment of self-perceived mate value and provided evidence that the relationship between mate value and life history strategy may be moderated by mate value trait heritability. Specifically, the relationship between mate value and life history strategy was found to be significantly stronger for those mate value traits with the lowest heritability estimates. Results are interpreted and discussed in terms of facultative calibration of evolved psychological mechanisms and conditional behavioral strategies.

摘要

生活史理论——考虑在生物体生命过程中发生的环境因素对决定发育和行为模式的影响——已被用于深入了解各种个体差异特征的原因和解释。最近的研究在这个列表中增加了配偶价值的个体差异，因此高配偶价值与缓慢的生活史策略相关。当前的研究在两项研究中复制并进一步探索了这种关系。与之前的研究一致，研究 1 表明生活史策略与自我感知配偶价值的一般评估之间存在中等相关性。研究 2 扩展了这项调查，包括对自我感知配偶价值的多因素评估，并提供证据表明配偶价值与生活史策略之间的关系可能受配偶价值特质遗传力的调节。具体而言，对于那些遗传力估计值最低的配偶价值特征，发现配偶价值与生活史策略之间的关系显着更强。结果在进化心理机制和条件行为策略的兼性校准方面进行了解释和讨论。
