非人类动物非常擅长判断以各种格式呈现的相对量，包括视觉，听觉，甚至交叉模态格式。性能通常受到集合之间的比率的限制，正如韦伯定律所预期的那样，并且如近似数系统（ANS）假设中所描述的那样。在大多数情况下，测试的目的是避免动物对刺激集的任何感知混乱，但尽管如此，动物还是会表现出一些人类基于刺激组织所表现出的感知偏差。在这里，我们展示了一个额外的感知偏差，出现从嵌套集的错觉。当计算机屏幕上显示一组圆圈，并将其分为大于或小于一个既定的中心值时，恒河猴（Macaca mulatta）低估了圆圈相互嵌套时的数量。这与之前的报告与成年人相匹配，表明猕猴和人类一样，表现出ANS估计预测的偏见感知模式。虽然一些猕猴克服了这种知觉偏差，证明他们可以来查看嵌套的刺激作为单独的元素，包括在用于分类阵列的数量估计，大多数猴子显示的偏见，低估嵌套阵列在整个实验。
Nonhuman animals are highly proficient at judging relative quantities presented in a variety of formats including visual, auditory, and even cross modal formats. Performance typically is constrained by the ratio between sets, as would be expected under Weber's Law, and as is described in the Approximate Number System (ANS) hypothesis. In most cases, tests are designed to avoid any perceptual confusion for animals regarding the stimulus sets, but despite this, animals show some of the perceptual biases that humans show based on organization of stimuli. Here, we demonstrate an additional perceptual bias that emerges from the illusion of nested sets. When arrays of circles were presented on a computer screen and were to be classified as larger than or as smaller than an established central value, rhesus monkeys (Macaca mulatta) underestimated quantities when circles were nested within each other. This matched a previous report with adult humans, indicating that macaques, like humans, show the pattern of biased perception predicted by ANS estimation. Although some macaques overcame this perceptual bias demonstrating that they could come to view nested stimuli as individual elements to be included in the estimates of quantity used for classifying arrays, the majority of the monkeys showed the bias of underestimating nested arrays throughout the experiment.
