Abstract: Objective To explore the impact of abacus mental calculation on children's numbers judgment. Method The study investigated numerical size judgment on both abacus mental children and common children who didn't receive abacus mental calculation (AMC) training by the application of event-related potential (ERP). Results According to behavioral data,the result showed reaction time that AMC children spending on numerical judgment was shorter than that of common children.According to ERP data,two groups' children had some differences at their early stage of number cognitive processing.Compared with common children,AMC children tended to have higher P1 amplitude in their occipital area and higher N1 amplitude in their prefrontal lobe.However,they turned to have lower P2 amplitude in their left frontal lobe and lower P3 amplitude in their parietal lobe.AMC children were proved to have faster P2 latency than that of common children. Conclusion AMC training can influence children at both early stage and middle stage of number processing.

摘要： 目的 探讨珠心算训练对儿童数字判断的影响,以提高儿童对数字认知加工的自动化程度。方法 采用事件相关电位(ERP)技术对珠心算儿童和非珠心算儿童的数字大小判断进行研究。结果 行为数据方面,珠心算儿童数字判断的反应时快于非珠心算儿童;ERP数据显示,两组儿童在数字认知加工的早期阶段存在一定差异,表现为珠心算儿童枕区P1、前额N1的波幅大于非珠心算儿童,而左侧额叶P2的波幅、左侧顶区P3的波幅小于非珠心算儿童,珠心算儿童P2潜伏期快于非珠心算儿童。结论 珠心算训练对儿童数字加工的早期和中期阶段有一定影响。
