在成人数字处理中,通常使用两种机制:数量的近似估计和精确计算。前者依赖于我们与动物和语言前婴儿共有的近似数感(ANS),而后者则依赖于精确数字系统(ENS),该系统在获得符号数字知识后在以后的生活中发展起来。当前的研究调查了高级数学教育对 ANS 和 ENS 的影响。我们的结果表明,高水平数学教育并没有显着改变非符号数量表示的精度。然而,数学成绩越高,符号数比较任务的表现以及在符号和非符号量之间准确映射的能力明显更好。我们的研究结果表明,成人的高水平数学教育对他们的 ANS 影响不大,但它似乎与更好的 ENS 锚定以及 ENS 和 ANS 之间更好的映射能力有关。
In adult number processing two mechanisms are commonly used: approximate estimation of quantity and exact calculation. While the former relies on the approximate number sense (ANS) which we share with animals and preverbal infants, the latter has been proposed to rely on an exact number system (ENS) which develops later in life following the acquisition of symbolic number knowledge. The current study investigated the influence of high level math education on the ANS and the ENS. Our results showed that the precision of non-symbolic quantity representation was not significantly altered by high level math education. However, performance in a symbolic number comparison task as well as the ability to map accurately between symbolic and non-symbolic quantities was significantly better the higher mathematics achievement. Our findings suggest that high level math education in adults shows little influence on their ANS, but it seems to be associated with a better anchored ENS and better mapping abilities between ENS and ANS.
