Six-month-old infants discriminate between large sets of objects on the basis of numerosity when other extraneous variables are controlled, provided that the sets to be discriminated differ by a large ratio (8 vs. 16 but not 8 vs. 12). The capacities to represent approximate numerosity found in adult animals and humans evidently develop in human infants prior to language and symbolic counting.
当其他无关变量得到控制时,6个月大的婴儿能够根据数量对大量物体进行区分,前提是要区分的两组物体数量差异较大(8对16,而不是8对12)。在成年动物和人类身上发现的表征近似数量的能力显然在人类婴儿掌握语言和符号计数之前就已经发展起来了。
