目前研究的目的是探索猴子是否拥有理解零所必需的概念前体。我们训练恒河猴在一个非符号的数字匹配到样本的任务，并在一个数字排序的任务。然后，我们引入了包含空集的无差异强化试验，以确定猴子是否会将空集视为数值。所有的猴子都成功地匹配并订购了空的集合，而没有任何训练。精确距离效应。表明他们把空集当作数值连续体上的值。
The goal of the current research was to explore whether monkeys possess conceptual precursors necessary for understanding zero. We trained rhesus monkeys on a nonsymbolic numerical matching-to-sample task, and on a numerical ordering task. We then introduced nondifferentially reinforced trials that contained empty sets to determine whether monkeys would treat empty sets as numerical values. All monkeys successfully matched and ordered the empty sets without any training. Accuracy distance effects. indicating that they treated empty sets as values on a numerical continuum.
