Probabilistic betting tasks Experiment and Colored-ball betting tasks Experiment.

Following the traditional setup of the Allais-type betting task, two behavioral experiments including eight sets of betting tasks were designed using the first set of betting tasks in the Allais paradox as the base template. One set of experiments describes the base rate information of the tasks in the form of probabilistic combinations in order to better restore the decision environment of the traditional Alley-type betting tasks. The other set of experiments were based on Experiment 1, which replaced the probabilistic combination descriptions with frequency representations supplemented with visual images (Colored-ball betting tasks) to again examine the subjects' decision-making.

遵循阿莱类投注任务（Allais-type betting task）的传统实验范式，本研究以阿莱悖论（Allais paradox）中的首组投注任务为基础模板，设计了包含八组投注任务的两项行为实验。其中一项实验以概率组合的形式呈现任务的基础率信息，以更精准地还原传统阿莱类投注任务的决策情境。另一项实验则以第一项实验为基础，将概率组合描述替换为辅以视觉图像的频率表征形式（彩球投注任务，Colored-ball betting tasks），以此再次探究被试的决策行为。
