第一次在非常年轻的非人类动物中研究了数字能力。鸡（Gallus gallus）学会了识别一系列的10个相同的位置（实验1）的第3，第4，或第6位。空间信息的使用（即，距离）被排除在实验2（小鸡概括的强化反应的刺激旋转了90相比，训练）和实验3（小鸡概括了他们的反应，一系列的单一位置之间的距离已被操纵）。小鸡找到了正确的位置，即使身份和距离的每个位置从审判到审判（实验4）。总体而言，年轻的小鸡似乎使用序数时，需要确定其数字序列位置的目标。
Numerical competencies were investigated for the 1st time in very young nonhuman animals. Chicks (Gallus gallus) learned to identify the 3rd, 4th, or 6th positions in a series of 10 identical positions (Experiment 1). Use of spatial information (i.e., distances) was ruled out in Experiment 2 (chicks generalized the reinforced response to an array of stimuli rotated by 90 as compared with training) and Experiment 3 (chicks generalized their response to a series in which distances between the single positions had been manipulated). Chicks found the correct position even when both identity and distance of each position changed from trial to trial (Experiment 4). Overall, young chicks seemed to use ordinality when required to identify a target by its numerical serial position.
