To support the claim that the approximate number system (ANS) represents rational numbers, Clarke and Beck (C&B) argue that number perception is abstract and characterized by a second-order character. However, converging evidence from visual illusions and psychophysics suggests that perceived number is not abstract, but rather, is perceptually interdependent with other magnitudes. Moreover, number, as a concept, is second-order, but number, as a percept, is not.
为了支持近似数量系统（ANS）表示有理数的观点，克拉克和贝克（C&B）认为，数字感知是抽象的，具有二阶特征。然而，来自视觉错觉和心理物理学的一致证据表明，感知到的数字不是抽象的，而是与其他量在感知上相互依赖。此外，数字作为一个概念是二阶的，但作为一个感知，它不是二阶的。
