The temporal discounting literature has demonstrated that the loss in value for delayed outcomes is most accurately modeled using a hyperbolic discounting equation. The hyperbolic-shaped function not only describes the shape of discounting for monetary outcomes, but also for other tangibles, such as alcohol, candy, CDs, erotica, cigarettes, cocaine, books, and DVDs. Furthermore, this hyperbolic shape has important theoretical implications. Despite the broad list of outcomes that are hyperbolically discounted, one class of outcomes has only recently received attention: social interactions. For the present study, we used standard binary-choice discounting procedures to explore the function that most accurately describes the change in value of delayed social interactions. The results from the present study suggest that, for 93 participants, the same equations (exponential, hyperbolic, and hyperboloid) used to describe the discounting of nonsocial commodities also describe the relation between delay and the value of social interaction. Similar to previous findings for nonsocial outcomes, the hyperbolic-shaped models provide a fit to the data superior to that of the exponential model.
时间折扣文献表明，对于延迟结果的价值损失，使用双曲线折扣方程能最准确地进行建模。这种双曲线形状的函数不仅描述了货币结果的折扣形状，也描述了其他有形物品的折扣形状，如酒精、糖果、CD、色情作品、香烟、可卡因、书籍和DVD。此外，这种双曲线形状具有重要的理论意义。尽管有大量结果是以双曲线方式进行折扣的，但有一类结果直到最近才受到关注：社会互动。在本研究中，我们使用标准的二元选择折扣程序来探索最准确描述延迟社会互动价值变化的函数。本研究结果表明，对于93名参与者而言，用于描述非社会商品折扣的相同方程（指数方程、双曲线方程和双曲面方程）也描述了延迟与社会互动价值之间的关系。与之前关于非社会结果的研究结果相似，双曲线形状的模型对数据的拟合优于指数模型。
