为了评估货币决策过程的跨文化共性，美国，中国和日本的研究生进行了两个任务：在延迟折扣任务中，参与者在即时和延迟的假设性货币奖励之间进行选择;在概率折扣任务中，参与者在确定性和概率性奖励之间进行选择。观察到一些显著的跨文化相似性。双参数双曲线函数描述了所有三组的延迟和概率折扣。此外，对于所有三组，延迟奖励的贴现率对于较小的金额较高，而概率奖励的贴现率对于较小的金额较低。还观察到一些组间差异。根据经验贴现曲线下的面积来衡量，美国人和中国人对延迟奖励的贴现率比日本人更高。此外，美国人对概率回报的折扣最大，而中国人对概率回报的折扣最小。尽管存在这些差异，但贴现函数形式和数量效应的相似性表明，这三个群体在评估延迟和概率奖励的过程中存在基本的共同点。
In order to assess the cross-cultural generality of monetary decision-making processes, American, Chinese, and Japanese graduate students were studied on two tasks: In the delay discounting task, participants made choices between immediate and delayed hypothetical monetary rewards; in the probability discounting task, participants made choices between certain and probabilistic rewards. Some notable cross-cultural similarities were observed. Two-parameter hyperbola-like functions described both delay and probability discounting for all three groups. Moreover, for all three groups the rate at which delayed rewards were discounted was higher for the smaller amount whereas the rate at which probabilistic rewards were discounted was lower for the smaller amount. Some group differences were also observed. As measured by the area under the empirical discounting curve, the Americans and Chinese discounted delayed rewards more steeply than the Japanese. In addition, the Americans discounted probabilistic rewards the most, whereas the Chinese discounted probabilistic rewards the least. Despite these differences, the similarities in the form of the discounting functions and in the effects of amount suggest that there are fundamental commonalities among the three groups with respect to the processes underlying their evaluation of delayed and probabilistic rewards.
