This research project studies the evolution of cognitive capacities for human agents and the implications for strategic behavior in potentially cooperative social interactions. The research starts from the idea that people are political beings with special purpose information processing capacities for dealing with cooperative and conflictual encounters. The baseline environment for these interactions is taken from evolutionary game theory in which individuals are randomly matched to play a variety of 2-person games, including prisoner's dilemma, games of pure conflict and cooperative games. What is new and different in this research is that an actor's strategy is contingent on the counterpart's characteristics (e.g., strength or frequency of cooperative behavior). Moreover actors have a capacity to verify or misrepresent their own characteristics. The communication and cognitive abilities of those actors are subject to evolutionary selection. All of this activity takes place in well defined computer simulations that run through tens of thousands of generations with large groups of individuals. The results illustrate the conditions under which cooperation can emerge in a variety of environments.

该研究项目研究人类代理人认知能力的演变以及潜在合作社会互动中战略行为的影响。 这项研究的出发点是，人是具有特殊目的的信息处理能力的政治存在，可以处理合作和冲突的遭遇。 这些互动的基线环境取自进化博弈论，其中个体被随机匹配以玩各种2人游戏，包括囚犯困境，纯冲突游戏和合作游戏。 在这项研究中，新的和不同的是，行动者的策略取决于对手的特征（例如，合作行为的强度或频率）。 此外，行为者有能力核实或歪曲自己的特点。 这些行为者的沟通和认知能力受到进化选择的影响。 所有这些活动都发生在定义明确的计算机模拟中，这些模拟在大型个体群体中进行了数万代。 研究结果说明了在何种条件下，合作可以出现在各种环境。
