人类与非人类动物共享一种近似数字系统(ANS),该系统允许在没有符号的情况下估计和粗略计算数字。最近的研究表明,ANS的敏锐度与符号数学在整个发育阶段和成年后的表现之间存在相关性,这表明ANS可能是人类独特的符号数学能力的认知基础。这样的命题导致了一种未经检验的预测,即旨在提高ANS成绩的训练将转移到符号数学的改进上。在这里,在两个实验中,我们证明了ANS对点数组的近似加法和减法的训练,选择性地改进了符号加法和减法。这一发现有力地支持了这一假设,即复杂的数学技能从根本上与基本的言语前量化能力有关,提供了第一个直接证据,表明ANS和符号数学可能是因果关系的,并增加了针对ANS的干预可能会使数学困难的儿童和成年人受益的可能性。
Humans share with nonhuman animals an approximate number system (ANS) that permits estimation and rough calculation of number without symbols. Recent studies show a correlation between the acuity of the ANS and symbolic math performance throughout development and into adulthood, suggesting that the ANS may serve as a cognitive foundation for the uniquely human capacity for symbolic mathematics. Such a proposition leads to the untested prediction that training aimed at improving ANS performance will transfer to improvement in symbolic mathematics. Here, in two experiments, we show that ANS training on approximate addition and subtraction of arrays of dots, selectively improves symbolic addition and subtraction. This finding strongly supports the hypothesis that complex math skills are fundamentally linked to rudimentary preverbal quantitative abilities, provides the first direct evidence that ANS and symbolic math may be causally related, and raises the possibility that interventions aimed at the ANS could benefit children and adults who struggle with math.
