Correlational research has linked low mate value (MV)--one's worth as a mating partner to members of the opposite sex--with aggression in men. In 2 experiments, we examined the effects of self-perceived MV on men's reported willingness to aggress directly toward a hypothetical mate poacher (Experiment 1, N = 60) and observable aggression toward a same-sex rival in a laboratory paradigm (Experiment 2, N = 54). In both experiments, the roles of narcissism in moderating the effect of MV condition on subsequent aggression were examined. Results of Experiment 1 indicated that men randomly assigned to the low MV condition were significantly more willing to report aggressive intention than men in the high MV condition. This relationship was moderated by narcissism such that men in the low MV condition who were also high in narcissism were the most likely to aggress. Results of Experiment 2 similarly showed that men in the low MV condition relative to the high MV condition aggressed more toward a same-sex rival when they were high in narcissism. These findings support evolutionary hypotheses surrounding the importance of self-perceived MV in directing aggressive mating efforts, as situated in the framework of threatened egotism.

威胁男人的伴侣价值会影响向异性恋竞争的侵略：自恋的调节作用。

相关研究已将低配偶价值（MV）与男性的攻击性联系在一起，该价值是作为异性成员交配伴侣的价值。在2个实验中，我们检查了自我感知的MV对男性报告的直接向假想的偷猎者进攻的意愿（实验1，N = 60）和在实验室范式中对同性竞争对手的可观察到的进攻（实验2）的影响。 N = 54）。在两个实验中，都研究了自恋在减轻MV条件对后续侵略的影响中的作用。实验1的结果表明，与处于高MV状态的男性相比，被随机分配到低MV状态的男性明显更愿意报告侵略性意图。自恋使这种关系得以缓和，因此自恋程度也较高的处于低MV状况的男人最容易侵略。实验2的结果类似地显示，相对于高MV状况，处于低MV状况的男人在自恋率高的时候更倾向于同性对手。这些发现支持进化假说，围绕着自我感知的MV在指导积极的交配努力中的重要性，这种情况位于受威胁的自我主义的框架中。
