虽然婴儿非符号数字表征的心理物理学已经得到了很好的研究，但对幼儿近似数字系统（ANS）的其他特征知之甚少。在这里，三个实验通过测试婴儿跨感觉模态转移近似数字表征的能力来探索ANS产生抽象表征的程度。这些实验表明，6个月大的婴儿将他们听到的声音的大致数量与他们看到的大致数量相匹配，更长时间地观察与之前听到的听觉序列在数字上不匹配的视觉阵列。当视觉和声音以1:3和1:2的比例不匹配，而不是2:3的比例不匹配时，可以观察到这种视觉偏好。这些发现表明，婴儿可以使用存储在记忆中的表征来比较以不同方式获得的数字信息。此外，6个月大的婴儿对多模态数字序列的比较的敏锐度似乎与他们对单模态序列的比较相似。
Although the psychophysics of infants’ non-symbolic number representations has been well studied, less is known about other characteristics of the Approximate Number System (ANS) in young children. Here, 3 experiments explored the extent to which the ANS yields abstract representations by testing infants’ ability to transfer approximate number representations across sensory modalities. These experiments showed that 6-month old infants matched the approximate number of sounds they heard to the approximate number of sights they saw, looking longer at visual arrays that numerically mis-matched a previously heard auditory sequence. This looking preference was observed when sights and sounds mismatched by 1:3 and 1:2 ratios, but not by a 2:3 ratio. These findings suggest that infants can compare numerical information obtained in different modalities using representations stored in memory. Furthermore, the acuity of 6-month old infants’ comparisons of intermodal numerical sequences appears to parallel that of their comparisons of unimodal sequences.
