人们对经济行为的演变非常感兴趣。在典型的研究中，物种被要求玩博弈论衍生的一系列经济博弈中的一种，并比较它们的反应。这种方法的优势是游戏本身产生的相对水平的一致性和控制力；然而，在典型的实验中，程序和条件差别很大，特别是在人类和其他物种之间。因此，在目前的研究中，我们调查了三个灵长类物种，卷尾猴、黑猩猩和人类如何使用尽我们所能在不同物种之间进行保证(或Stag Hunt)游戏的程序，特别是在训练和预测试方面。我们的目标是确定这些物种在这场游戏中做出决定的方式是否存在差异。我们假设了系统发育路线上的差异，这是我们发现的。然而，这两个物种的相似性可能比预期的要大。特别是，使用“非人类灵长类动物友好”规则游戏的人类的行为并不像典型的那样。因此，我们找到了在各目灵长类动物中决策过程相似的证据。这些结果表明，这种比较研究是可能的，而且，在对物种的相对能力进行任何比较时，必须极其小心地确保一个物种不会因为方法程序而相对于其他物种具有优势。
There is great interest in the evolution of economic behavior. In typical studies, species are asked to play one of a series of economic games, derived from game theory, and their responses are compared. The advantage of this approach is the relative level of consistency and control that emerges from the games themselves; however, in the typical experiment, procedures and conditions differ widely, particularly between humans and other species. Thus, in the current study, we investigated how three primate species, capuchin monkeys, chimpanzees, and humans, played the Assurance (or Stag Hunt) game using procedures that were, to the best of our ability, the same across species, particularly with respect to training and pretesting. Our goal was to determine what, if any, differences existed in the ways in which these species made decisions in this game. We hypothesized differences along phylogenetic lines, which we found. However, the species were more similar than might be expected. In particular, humans who played using "nonhuman primate-friendly" rules did not behave as is typical. Thus, we find evidence for similarity in decision-making processes across the order Primates. These results indicate that such comparative studies are possible and, moreover, that in any comparison rating species' relative abilities, extreme care must be taken in ensuring that one species does not have an advantage over the others due to methodological procedures.
