Abstract:

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
