摘要

剥削战略包括剥夺他人的资源，同时加强自己的资源。生活史理论认为，个体差异(生活史策略)和环境特征(生活史偶然性[lhc])会影响利用策略的使用。然而，过去操纵lhc的工作发现了这些信息对剥削行为影响的混合证据。我们提出了三个研究来帮助澄清这类信息的影响。结果表明，年轻个体对LHC信息最为敏感。我们还发现，与预测相反，传递缓慢的LHC信息(即高种群密度、种内竞争和资源稀缺)会增加而不是减少参与剥削行为的诱惑。讨论了局限性和未来发展方向。

Life History Theory and Exploitative Strategies

Exploitative strategies involve depriving others of resources while enhancing one’s own. Life history theory suggests that there are individual differences (life history strategy) and environmental characteristics (life history contingencies [LHCs]) that influence the use of exploitative strategies. However, past work manipulating LHCs has found mixed evidence for the influence of this information on exploitative behavior. We present three studies that help clarify the effects of this type of information. Results indicated that younger individuals are most sensitive to LHC information. We also found, contrary to predictions, that communicating slow LHC information (i.e., high population density, intraspecific competition, and resource scarcity) increased rather than decreased the temptation to engage in exploitative behavior. Limitations and future directions are discussed.
