虽然每个人都能感知到近似的数字，但有些人的估计比其他人更准确。这种估计的准确性称为近似数字系统（ANS）敏锐度。最近，几项研究报告称，幼儿的ANS敏锐度的个体差异与他们对精确数字（如单词“6”）的知识相关（Mussolin et al., 2012, Trends Neurosci）。建造。， 1,21；Shusterman et al., 2011，连接早期数字词知识与近似数字系统敏锐度；Wagner & Johnson, 2011，《认知》，119,10；参见abure - mendoza et al., 2013, Front。Psychol。， 4, 1)。这项研究认为这种相关性不应该被信任。这似乎是用于评估儿童ANS敏锐度的程序的人工产物。这种相关性的产生是因为：(1)一些实验设计无意中允许儿童根据显示中的点的大小（而不是数量）正确回答，以及/或(2)对数字知之甚少的幼儿可能不理解“更多点”这句话意味着数字上的更多。当任务被修改以确保儿童以数字为基础作出反应时，正常发育儿童的ANS敏锐度与精确数字知识之间的相关性就消失了。
Although everyone perceives approximate numerosities, some people make more accurate estimates than others. The accuracy of this estimation is called approximate number system (ANS) acuity. Recently, several studies have reported that individual differences in young children's ANS acuity are correlated with their knowledge of exact numbers such as the word 'six' (Mussolin et al., 2012, Trends Neurosci. Educ., 1, 21; Shusterman et al., 2011, Connecting early number word knowledge and approximate number system acuity; Wagner & Johnson, 2011, Cognition, 119, 10; see also Abreu-Mendoza et al., 2013, Front. Psychol., 4, 1). This study argues that this correlation should not be trusted. It seems to be an artefact of the procedure used to assess ANS acuity in children. The correlation arises because (1) some experimental designs inadvertently allow children to answer correctly based on the size (rather than the number) of dots in the display and/or (2) young children with little exact-number knowledge may not understand the phrase 'more dots' to mean numerically more. When the task is modified to make sure that children respond on the basis of numerosity, the correlation between ANS acuity and exact-number knowledge in normally developing children disappears.
