摘要： 采用数量判定任务，分别用2～30和5～100范围内点子图为刺激，研究个体“多”和“少”概念的发展。结果发现：在5～100点子条件下，随年龄的增长，个体“多”概念的判断值、“少”概念的判断值、“多”“少”概念的临界值均显著增大；7～9岁是个体“多少”概念发展的转折期；个体对“多少”概念的认知具有相对性；在本实验的两种条件下，随年龄增长，个体“多”概念的判断值、“少”概念的判断值、“多”“少”概念的临界值逐渐趋于刺激点子数最大值的2/3、1/3、1/2，“多”概念与“少”概念判断的不确定距离逐渐趋于刺激点子数最大变化范围的1/3或略小于1/3。

关键词: 数概念, “多少”概念, 临界值, 不确定距离

Abstract: In the current research, the task of number discrimination was used to investigate the development of the concept of much and few. The numbers of 2 to 30 and 5 to 100 dots were presented to the subjects. The result showed that: on the condition of 5-100 dot numbers, the discrimination of much and few numbers is developed with age; the age from 7 to 9 is a critical period of developing concept of much and few numbers; the children discriminate much and few numbers relatively; on the two conditions of the research, the critical value and the discrimination of much and few numbers become the most numbers of the stimulated dots of 2/3, 1/3 and 1/2 increasingly, but the undefined distance of discriminating much and few numbers is in the range of 1/3 stimulat?鄄ed dots or less than 1/3.

Key words: number concept, much and few, critical value, undefined distance
