近似数量系统(Approximate Number System, ANS)指个体在不需要依赖于计算和数量符号的情况下, 对一组数量进行近似表征的系统。通过总结近十年来研究者们在ANS的遗传和神经基础、干预训练等方面取得的新进展, 指出未来应综合运用各种认知神经科学研究手段立足于ANS的基因和脑生理基础研究, 进一步揭示ANS的本质和内在发生发展机制, 并将有关研究发现运用到教育教学中, 对数学困难儿童进行干预, 以提高其数学能力和适应社会的能力。

关键词: 近似数量系统(ANS), 遗传和神经基础, 顶内沟(IPS), 干预


Approximate number system (ANS) refers to a system with which an individual can represent a set of numbers approximately without calculation and numerical symbols. We firstly sum up the recent development in heredity, neural basis and the intervention training of ANS at home and abroad within the last decade. Then we point out that, basing on the genetic and brain physiological researches, further researches should reveal the nature and inherent developing mechanism of ANS by means of cognitive neuroscience, and apply the findings into teaching. For example, our findings can help children poor in math to improve their mathematical skills and ability to adapt to the society.

Key words: approximate number system (ANS), genetic and neural basis, intraparietal sulcus (IPS), interventions
