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 analyze the influence of abacus training time on children’s digital perception and provide the basis for the related research of children’s cognitive abilities. Methods Event-related potentials (ERPs) were used to measure the number-based mental arithmetic in 14 first-year primary school students who received abacus abacus training and 14 first-year primary school students who did not receive abacus abacus training. Results The average amplitudes of P1 (10.11μV) and N1 (11.27μV) in the first grade children in the training group were greater than those in the third grade children (9.67μV) and N1 (7.40μV). The incubation period of the first grade children in training group was 212.02 ms) is greater than the third-year children’s P2 (200.37ms) incubation period. No significant changes in amplitude and latency were found in the untrained group. Conclusion The abacus calculation training time is closely related to children’s early perception processing of numbers.
