尽管在非人类动物身上有许多算术能力的证明，但关于动物如何列举运动刺激的情况却知之甚少。在这一系列实验中，恒河猴(Macaca Mulatta)和卷尾猴(Cebus Apella)进行了计算机化的任务，在这些任务中，它们必须列举刺激集合。在实验1中，恒河猴比较了两组运动刺激。实验2要求对运动集合和静态集合进行比较。实验3包括人类参与者和卷尾猴，以评估所有3个物种的表现，并确定是否对刺激集的14个数字属性做出反应，而不是对其他一些刺激属性，如累积面积。实验4要求两种猴子列举每个移动阵列的子集。在所有实验中，猴子的表现都高于概率水平，它们的反应由阵列中的项目数量控制，而不是非数字刺激维度。尽管卷尾猴的表现较低，但与成年人类相比，恒河猴的表现与成年人类相当。
Despite many demonstrations of numerical competence in nonhuman animals, little is known about how well animals enumerate moving stimuli. In this series of experiments, rhesus monkeys (Macaca mulatta) and capuchin monkeys (Cebus apella) performed computerized tasks in which they had to enumerate sets of stimuli. In Experiment 1, rhesus monkeys compared two sets of moving stimuli. Experiment 2 required comparisons of a moving set and a static set. Experiment 3 included human participants and capuchin monkeys to assess all 3 species' performance and to determine whether responding was to the numerical 14 properties of the stimulus sets rather than to some other stimulus property such as cumulative area. Experiment 4 required both monkey species to enumerate subsets of each moving array. In all experiments, monkeys performed above chance levels, and their responses were controlled by the number of items in the arrays as opposed to nonnumerical stimulus dimensions. Rhesus monkeys per-formed comparably to adult humans when directly compared although capuchin performance was lower.
