学前儿童近似数量系统敏锐度与符号数学能力的关系

122 3 to 6-year-old children participated in our study to complete 11 measures to access ANS acuity, symbolic number abilities, inhibitory control, short memory, working memory and receptive vocabulary. The results indicated: (1)With the age increasing, ANS acuity of preschool children continues to increase. (2)Subjects performed significantly above chance level in all ANS acuity tasks，but the performance of non-symbolic magnitude comparison task was better than same-different task. The main effect of age and ratio were significant in these two tasks. These results indicated the same different task is applicable to measure ANS acuity of preschool children. (3) After controlling for short memory, working memory, inhibitory control and receptive vocabulary, the weber faction calculated by non-symbolic magnitude comparison task correlated with cardinality proficiency and symbolic number knowledge, while the accuracy of this task correlated with counting skills, cardinality proficiency and symbolic number knowledge. (4) After controlling for other variables, the total accuracy of same different task did not correlated with symbolic number abilities, while the accuracy of different trails correlated with symbolic number knowledge.
