Learning and Decision Costs in Experimental Constant Sum Games
通过实验研究玩家在常和博弈中的行为，发现其偏离纳什均衡，而刺激学习模型能最好地解释动态博弈模式，对理解人类决策和学习机制有参考价值。
Subjects played strategically similar 4 × 4 and 6 × 6 constant sum games under varying payoff scales. Substantial divergences from equilibrium predictions were exhibited. The dynamic pattern of play is best explained by a stimulus learning model whereby players allocate weight to different actions according to their relative (time average) payoff experience in past plays. The results do not provide much support for the hypothesis that players select best responses to beliefs about opponent play based on observed choice frequencies in past plays, modified by random errors or preference shocks.Journal of Economic LiteratureClassification Numbers: C72, C92.
