卷尾猴（Cebus apella）进行了一项反向奖励任务的测试，该任务涉及不同数量的相同食物或相同数量的不同食物。所有的猴子首先测试的定性版本自发地掌握了任务，而只有四分之一的自发地掌握了定量版本。当任务转换时，没有猴子达到标准，尽管在研究后几乎所有猴子都进行了补救程序。结果表明，（a）定性的反向奖励比定量版本的问题更容易，（B）质量和数量维度的处理不同的食物相关的任务，（c）僧帽猴可以表现出快速和自发的学习反向奖励的突发事件。
Capuchin monkeys (Cebus apella) were tested on a reverse-reward task involving different quantities of the same food, or an identical quantity of different foods. All monkeys tested first on the qualitative version spontaneously mastered the task, whereas only one of four spontaneously mastered the quantitative version. No monkey reached criterion when the tasks were switched, although almost all did so following remedial procedures after the study. The results suggest that (a) qualitative reverse-reward is easier than quantitative versions of the problem, (b) quality and quantity dimensions are processed differently in food-related tasks, and (c) capuchin monkeys can show rapid and spontaneous learning of reverse-reward contingencies.
