这项研究验证了一种假设，即潜在固有的近似数字系统(ANS)的敏锐性会导致数学学习障碍(MLD)的风险。对68名(35名男孩)面临学业失败风险的学龄前儿童进行了一系列量化任务以及智力、执行控制、识字前技能和父母教育的评估。学龄前一年结束时的数学成绩表明，这些孩子中有34人是 儿童的高危人群。相对于34名通常成绩优异的儿童，高危儿童在ANS任务上的准确性较低，在这项任务上，每少一个标准差就会导致MLD状态的几率增加2.4倍。高危儿童对顺序关系的理解也很差，对阿拉伯数字、数字单词及其基数值的学习速度较慢。在这些任务上的糟糕表现导致MLD状态的几率增加3.6到4.5倍。研究结果在一定程度上支持了ANS假说，但也表明这些缺陷并不是数学学习不良的主要原因。
The study tested the hypothesis that acuity of the potentially inherent approximate number system (ANS) contributes to risk of mathematical learning disability (MLD). Sixty-eight (35 boys) preschoolers at risk for school failure were assessed on a battery of quantitative tasks, and on intelligence, executive control, preliteracy skills, and parental education. Mathematics achievement scores at the end of 1 year of preschool indicated that 34 of these children were at high risk for MLD. Relative to the 34 typically achieving children, the at risk children were less accurate on the ANS task, and a one standard deviation deficit on this task resulted in a 2.4-fold increase in the odds of MLD status. The at risk children also had a poor understanding of ordinal relations, and had slower learning of Arabic numerals, number words, and their cardinal values. Poor performance on these tasks resulted in 3.6- to 4.5-fold increases in the odds of MLD status. The results provide some support for the ANS hypothesis but also suggest these deficits are not the primary source of poor mathematics learning.
