Altruistic choice can be described quantitatively by social discount functions that indicate how rewards decrease in value with increases in social distance. Reciprocation from others has been implicated as an influential variable for altruistic choice. To investigate reciprocation and social discounting, a novel reciprocal discounting task asked participants to report what various individuals on their list would choose between money for themselves and money for the participant. Results from 150 participants show that reciprocal discounting is well-fit by Mazur’s hyperbolic equation and correlates significantly with social discounting.

互惠折扣：一项初步研究

利他的选择可以通过社会折扣函数来定量描述，该函数表明奖励如何随着社会距离的增加而降低价值。他人的回报已被认为是利他选择的影响变量。为了研究往复和社会贴现，一项新颖的往复贴现任务要求参与者报告他们名单上的各个个人将在自己的钱和参与者的钱之间进行选择。来自150名参与者的结果表明，相互折让通过Mazur的双曲方程非常吻合，并且与社会折衷显着相关。
