Studying Learning in Games Using Eye-Tracking
通过眼动追踪记录玩家在4x4标准型博弈中的信息获取，发现眼动数据支持复杂学习（如预期对手行为）而非简单适应学习，但决策数据与简单预期模型拟合不佳。
We report results from an exploratory study using eye-tracking recording of information acquisition by players in a game theoretic learning paradigm. Eye-tracking is used to observe what information subjects look at in 4times4 normal-form games; the eye-tracking results favor sophisticated learning over adaptive learning and lend support to anticipatory or sophisticated models of learning in which subjects look at payoffs of other players to anticipate what those players might do. The decision data, however, are poorly fit by the simple anticipatory models we examine. We discuss how eye-tracking studies of information acquisition can fit into research agenda seeking to understand complex strategic behavior and consider methodological issues that must be addressed in order to maximize their potential.
