Research by (3), 433-440. doi:10.1007/s40732-014-0052-9, (2014) demonstrated the novel finding that the magnitude effect for medical outcomes does not reverse across delay and probability discounting as it does for monetary outcomes. We suggest that a possible reason for the lack of a reverse magnitude effect in nonmonetary outcomes is incomparable divisibility of discounted alternatives. To test whether the lack of a reverse magnitude effect in probability discounting of medical outcomes is due to incomparable divisibility of treatment effects, 4 studies were conducted. In the replication study, the effect observed by (3), 433-440. doi:10.1007/s40732-014-0052-9, (2014) was marginally not significant, although it was directionally consistent with their prediction of steeper discounting of small medical outcomes (as compared to large, defined as brain cancer) both in time and probability discounting. Our manipulation by substituting a divisible outcome (body paralysis) for an indivisible one (brain cancer) did not, however, bring expected results. We discuss the explanations and possible implications of introduced division for divisible and nondivisible medical outcomes.
（3）（2014年，第433 - 440页，doi:10.1007/s40732-014-0052-9）的研究表明了一个新发现，即医疗结果的量级效应不像货币结果那样在延迟和概率折扣中发生反转。我们认为，非货币结果中缺乏反转量级效应的一个可能原因是贴现选项的可分性不可比。为了检验医疗结果概率折扣中缺乏反转量级效应是否是由于治疗效果的可分性不可比，我们进行了4项研究。在重复研究中，（3）（2014年，第433 - 440页，doi:10.1007/s40732-014-0052-9）观察到的效应勉强不显著，尽管在时间和概率折扣方面，其方向与他们对小医疗结果（与大的结果相比，大的结果定义为脑癌）折扣更陡峭的预测一致。然而，我们用可分结果（身体瘫痪）替代不可分结果（脑癌）的操作并没有带来预期的结果。我们讨论了引入可分性对可分和不可分医疗结果的解释及可能的影响。
