Infants are capable of discriminating, representing, and remembering particular small numbers of items. A perceptual enumeration process called subitizing, present in 2-year-olds, probably underlies this capacity. This finding indicates that some number capacity is present before the onset of verbal counting, and it suggests that verbal counting may have precursors present during infancy.
婴儿能够辨别、表征和记住特定数量的少量物品。一种名为“数感”的感知计数过程存在于两岁儿童中，可能是这种能力的基础。这一发现表明，在口头计数开始之前就存在一些数字能力，并且表明口头计数在婴儿期可能就有其前身。
