一对繁殖中的猩猩（Pongo pygmaeus）可以自由地同时进行明暗辨别问题。在连续20次正确回答后，附带事件被逆转。系统的结果没有得到典型的实验室分离。从第一次逆转开始，对标准的反应急剧增加。这种增长在前10次逆转中是明显的。与实验室结果一致，逆转所需的反应数量明显减少，随之而来的是相对稳定。猩猩在这个相对简单的任务上表现出了出色的能力，但并没有达到一致的完美反转行为。响应水平受学习曲线的整体形状影响，但不受影响，这表明稳定的表现水平是环境复杂性和物种能力的函数。
A breeding orangutan [Pongo pygmaeus] pair was given free access to a simultaneous light-dark discrimination problem. Contingencies were reversed after 20 consecutive correct responses. Systematic results were obtained without typical laboratory isolation. There was a dramatic increase in responses to criterion beginning with the 1st reversal. This increase was evident for the first 10 reversals. In keeping with laboratory results, a marked shift toward decreasing numbers of responses required for reversals was followed by relative stability. Orangutans demonstrate excellent capability on this relatively simple task, yet do not achieve consistent perfect reversal behavior. The level of responding is influenced but not the overall shape of the learning curve, suggesting that the stable performance level is a function of environmental complexity as well as species capability.
