Previous studies using Western samples have found that introducing uncertainty to an intertemporal choice decreases the degree of discounting future rewards. The authors of this article examined the effect of risk on intertemporal choice using Chinese participants and found that respondents preferred the smaller but sooner (SS) outcome to the larger but later (LL) one in the presence of risk, which indicates that risk increases rather than decreases the degree of discounting future rewards. Thus, variations in response patterns between different cultural groups suggest that culture may play an important role in intertemporal choice and researchers should delve into this topic from an emic rather than an etic perspective.
先前的使用西方样本的研究发现，在跨期选择中引入不确定性会降低对未来奖励的折扣程度。本文的作者使用中国参与者研究了风险对跨期选择的影响，发现当存在风险时，被试者更喜欢较小但较早的（SS）结果而不是较大但较晚的（LL）结果，这表明风险增加而不是降低了对未来奖励的折扣程度。因此，不同文化群体之间反应模式的差异表明，文化可能在跨期选择中发挥重要作用，研究人员应该从本土而不是从外来的角度深入探讨这个问题。
