Elderly (greater than 23 years) rhesus monkeys, some of whom had previous learning test experience, were tested on a standardized battery of discrimination and concept-formation tasks, and their performance was compared with that of test-naive middle-aged (15 years) and juvenile (2 years) monkeys. Naive elderly monkeys performed more poorly on virtually all tasks compared to their younger counterparts. In contrast, test-experienced elderly monkeys outperformed both middle-aged and juvenile monkeys on those problem types with which they had limited previous experience, despite the fact that 8-10 years had passed since their prior training. However, test-experienced elderly monkeys did not display superior performance on new tests that approximated visual acuity or assessed delayed discrimination capabilities.
老年（超过23岁）恒河猴，其中一些有过学习测试经验，接受了一系列标准化的辨别和概念形成任务测试，并将它们的表现与无测试经验的中年（15岁）和幼年（2岁）猴子进行比较。与较年轻的同类相比，无经验的老年猴子在几乎所有任务上表现更差。相比之下，有测试经验的老年猴子在那些它们之前经验有限的问题类型上表现优于中年和幼年猴子，尽管自它们之前的训练已经过去了8 - 10年。然而，有测试经验的老年猴子在近似视力或评估延迟辨别能力的新测试中并未表现出卓越的表现。
