Two groups of five young adult an older stumptailed macaques (Macaca arctoides) were tested on a visual discrimination task followed by a reversal upon attainment of criterion; task and reversal were repeated until 20 reversals with the same pair of objects had been completed. Both groups required more trials to learn the first reversal than the original discrimination, with no significant difference between the groups. Older monkeys tended to show more perseverative errors on early reversals, but a striking improvement in their scores across successive blocks of reversals culminated in performances virtually indistinguishable from those of the young group by the end of testing.
两组各五只成年猕猴和一组五只老年短尾猕猴（Macaca arctoides）接受了视觉辨别任务测试，达到标准后进行反转；任务和反转重复进行，直到用同一对物体完成20次反转。两组在学习第一次反转时都比最初的辨别需要更多的试验，两组之间没有显著差异。老年猴子在早期反转时往往表现出更多的固执性错误，但在连续的反转块中，它们的分数有显著提高，到测试结束时，其表现与年轻组几乎没有区别。
