三只恒河猴（Macaca mulatta）被训练以升序、降序或非单调的数字顺序（1 <$2 <$3 <$4、4 <$3 <$2 <$1、3 <$1 <$4 <$2）对1、2、3和4的样本做出反应。然后测试猴子对新数字5-9进行排序的能力。在实验1中，所有3只猴子都按升序或降序排列数字1-4的新样本。尝试训练非单调顺序（3 <$1 <$4 <$2）失败。在实验2A中，学习了升序数字规则的两只猴子在未强化的试验中排列了成对的新数字5-9。学习了数字递减规则的猴子无法将递减规则外推到新的数字上。在实验2B中，所有3只猴子都订购了数字对5-9的新样本。反应的准确性和潜伏期揭示了与人类参与者的先前发现类似的距离和幅度效应（RS Moyer & TK Landaeur，1967）。总的来说，这些研究表明，猴子至少在一个有序尺度上代表数字1-9。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Three rhesus monkeys (Macaca mulatta) were trained to respond to exemplars of 1, 2, 3, and 4 in an ascending, descending, or a nonmonotonic numerical order (1← 2← 3← 4, 4← 3← 2← 1, 3← 1← 4← 2). The monkeys were then tested on their ability to order pairs of the novel numerosities 5–9. In Experiment 1, all 3 monkeys ordered novel exemplars of the numerosities 1–4 in ascending or descending order. The attempt to train a nonmonotonic order (3← 1← 4← 2) failed. In Experiment 2A, the 2 monkeys who learned the ascending numerical rule ordered pairs of the novel numerosities 5–9 on unreinforced trials. The monkey who learned the descending numerical rule failed to extrapolate the descending rule to new numerosities. In Experiment 2B all 3 monkeys ordered novel exemplars of pairs of the numerosities 5–9. Accuracy and latency of responding revealed distance and magnitude effects analogous to previous findings with human participants (RS Moyer & TK Landaeur, 1967). Collectively these studies show that monkeys represent the numerosities 1-9 on at least an ordinal scale.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
