Tracking Decision Makers under Uncertainty
通过眼动追踪研究人们在两个彩票间选择的决策过程，发现决策者常分别比较奖金和概率，而非依赖期望效用计算，尤其在计算复杂时。
Eye tracking is used to investigate the procedures that participants employ in choosing between two lotteries. Eye movement patterns in problems where the deliberation process is clearly identified are used to substantiate an interpretation of the results. The data provide little support for the hypothesis that decision makers rely exclusively upon an expected utility type of calculation. Instead eye patterns indicate that decision makers often compare prizes and probabilities separately. This is particularly true when the multiplication of sums and probabilities is laborious to compute.
