Discounting is a useful framework for understanding temporal choices. A person who prefers $50 immediately over $100 in 1 month exhibits a higher discount rate than a person deciding to wait for the higher payoff. Although previous research shows that discount rates are domain‐specific, we propose an alternative to the domain specificity account. We suggest that differences in discounting alternatives across various domains may result not so much from the domains' nature per se but from differences in perceived attractiveness of the discounted alternatives. We replicated that an illustrative study evidencing domain specificity in discounting (Experiment 1) showed that people's subjective values of the payoffs in domains discounted in this experiment were different (Experiment 2) and used a novel method to match the attractiveness of the available alternatives across domains (Experiment 3). Finally, Experiment 4 showed that when matching was applied, the domain effect disappeared. We conclude that a magnitude effect can, at least partially, explain domain specificity in delay discounting.

幅度效应有助于延迟贴现中的域特异性

折扣是理解时间选择的有用框架。与一个人决定等待更高的回报的人相比，一个人在1个月内更喜欢$ 50而不是$ 100的人，其折扣率更高。尽管先前的研究表明折现率是特定于域的，但我们提出了一种替代域特定性帐户的方法。我们建议，跨域折价方案的差异可能不是由于域本身的本质所致，而是由折价方案的吸引力差异引起的。我们重复进行了一项说明性研究，该研究证明了折扣中的域特异性（实验1），表明人们 在此实验中，折扣域的收益的主观值是不同的（实验2），并使用一种新颖的方法来匹配跨域可用替代方案的吸引力（实验3）。最后，实验4表明，当应用匹配时，畴效应消失了。我们得出的结论是，幅度效应至少可以部分解释延迟折扣中的域特异性。
