In temporal discounting, when a smaller and sooner reward is selected over a larger and more delayed reward, the addition of a constant delay to both outcomes results in preference reversals. The present experimental study investigates preference reversals in social discounting, that is, allocating rewards based on social distance. The experiment was carried out on 140 participants asked to make hypothetical choices between a smaller reward for a socially closer person and a larger reward for a more distant person. The results showed that shifting both rewards by a constant and relatively large social distance caused a decrease of the discounting rate but only when concrete thinking about the recipients was not primed by the instructions. Shifting the rewards by a constant and relatively small distance caused steeper discounting, regardless of the type of instructions. Similarities and differences between temporal and social discounting are discussed in the context of these findings.

社会折扣：操纵解释水平和与社会更亲近的人的距离的影响

在时间折扣时，当在更大且更延迟的奖励中选择较小且较早的奖励时，对两种结果的增加延迟会导致偏好逆转。本实验研究调查了社会折扣中的偏好逆转，即根据社会距离分配奖励。该实验是针对 140 名参与者进行的，他们被要求在对社交距离较近的人给予较小奖励和对较疏远的人给予较大奖励之间做出假设性选择。结果表明，通过恒定且相对较大的社交距离来转移两种奖励会导致贴现率降低，但只有在指令未引发对接受者的具体思考时才会如此。将奖励移动一个恒定且相对较小的距离会导致更大的折扣，不管指令的类型。在这些发现的背景下讨论了时间贴现和社会贴现之间的异同。
