过去的研究表明，近似数字系统（ANS）的敏锐度的个体差异与儿童的数学能力有关。然而，最近的一些研究认为，这些协会可以解释通过共同依赖抑制控制。在这里，我们在两个独立的实验中验证了这一说法。在实验1中，42名5岁和6岁的儿童完成了非符号数字比较任务，以评估ANS敏锐度以及标准化的实验者管理的评估抑制控制和数学能力。儿童的准确性在数字比较任务和分数的数学评估显着相关，即使在抑制控制任务的性能控制。为了排除我们的研究结果是由于抑制控制任务的性质，在实验2中，我们管理一个不同的，计算机化的抑制控制任务，和类似的任务，以评估ANS敏锐度和数学能力，在实验1中，3-6岁的儿童（N = 169）。与实验1的结果类似，我们发现，在控制抑制控制任务的性能时，数字比较任务和数学能力的准确性之间的关联持续存在。总之，这些结果表明，ANS敏锐度是唯一与早期的数学能力，独立的抑制控制的影响，至少在儿童从中等到高SES的家庭。
Past research suggests that individual differences in the acuity of the approximate number system (ANS) are associated with children’s math abilities. However, some recent work has argued that these associations can be explained through shared reliance on inhibitory control. Here, we test this claim in two separate experiments. In Experiment 1, forty-two 5- and 6-year-old children completed a non-symbolic number comparison task to assess ANS acuity as well as standardized experimenter-administered assessments for inhibitory control and math ability. Children’s accuracy in the number comparison task and scores on the math assessment were significantly correlated, even when controlling for performance on the inhibitory control task. To rule out that our findings were due to the nature of the inhibitory control task, in Experiment 2, we administered a different, computerized inhibitory control task, and similar tasks to assess ANS acuity and math ability as in Experiment 1 to children aged 3–6 years (N = 169). Similar to the result of Experiment 1, we found that associations between accuracy in the number comparison task and math ability persisted when controlling for performance on the inhibitory control task. Together these results suggest that ANS acuity is uniquely associated with early math abilities, independent of the effect of inhibitory control at least in children from middle- to high-SES families.
