在一只雌性黑猩猩（Pan troglodytes）中评估了数字排序技能的感知和认知过程，该黑猩猩具有计算机辅助数字能力任务的经验。要求受试者将0-9范围内的3个数字排列成递增序列，偶尔进行探测试验（称为转换试验），其中第2和第3个数字的位置在选择第1个数字后立即交换。在这些试验中，错误被频繁地记录下来，而对中间数字的正确反应变得可靠地慢了。这些数据和其他数据表明，受试者在做出第一个选择之前，已经建立了（a）她选择数字的正确顺序和（B）导致正确答案的运动顺序。这些研究结果表明，一个3单元订购任务的支持，在黑猩猩，就像它在人类，计划，执行和监测阶段。
Perceptual and cognitive processes underlying the skill of ordering numerals were assessed in a female chimpanzee (Pan troglodytes) with previous experience in computer-assisted numerical competence tasks. The subject was required to order 3 numerals from the range of 0-9 into an ascending series, with occasional probe trials (referred to as switch trials) in which the positions of the 2nd and 3rd numerals were exchanged immediately after the selection of the 1st. On these trials, errors were scored frequently, whereas correct responses to the intermediate numeral became reliably slower. These and other data indicated that the subject had already established, before making the 1st choice, (a) the correct sequence in which she was to select the numerals and (b) the motor sequence leading to a,correct answer. These findings show that a 3-unit ordering task is supported in the chimpanzee, much as it is in humans, by planning, executing, and monitoring phases.
