摘要
目的分析珠心算训练时间对儿童数字感知的影响,为儿童认知能力的相关研究提供依据。方法采用事件相关电位(ERP)的方法,分别对14名接受珠心算训练的一年级小学生及14名未接受珠心算训练的一年级小学生进行了数物感知的心算实验。结果训练组一年级儿童的P1(10.11μV)、N1(11.27μV)的平均波幅大于三年级儿童P1(9.67μV)、N1(7.40μV)的平均波幅;训练组一年级儿童P2的潜伏期(212.02ms)大于三年级儿童P2(200.37ms)的潜伏期。未训练组没有发现波幅和潜伏期的显著变化。结论珠心算训练时间与儿童对数字早期的感知加工有密切的联系。
Objective To test the impact of the abacus training time on the children＇s perception of numbers and objects,and to provide evidence for the research of children＇s perception ability.Methods Fourteen receiving abacus training children not receiving abacus training did mental calculation of perception of numbers and objects with event-related potential（ERP）way.Results In the trained group,the amplitude of N1（11.27 μV）,P1（10.11 μV）and the latency of P2（212.02 ms）in the grade one were significantly higher than amplitude of P1（9.67 μV）,N1（7.40 μV）and latency of P2（200.37 ms）in the grade three.Conclusion There is a relationship between the training time and the children＇s early stage perception of numbers.
