摘　　要：目的 探讨珠心算训练对儿童形状识别的影响.方法 采用事件相关电位（ERP）技术对14名珠心算训练儿童和14名非珠心算训练儿童进行不同形状识别时的ERP记录,分析两组儿童不同脑区ERP波幅和潜伏期的差异.结果 （1）两组儿童枕部P1波幅差异显著,珠心算儿童的P1波幅[（9.59±3.58）μV]高于非珠心算儿童[（7.06 ±2.84）μV],差异具有显著性（P＜0.05）;（2）珠心算儿童右侧枕颞区N170波幅[（-9.83 ±2.97）μV]小于非珠心算儿童[（- 12.45 ±2.51）μV],差异具有显著性（P＜0.05）;（3）珠心算儿童前额P3波幅[（7.65 ±2.25）μV]大于非珠心算儿童[（4.89±3.35） μV],差异具有显著性（P＜0.05）.结论 珠心算训练对儿童形状识别的脑功能有一定影响.Objective To explore the influence of mental abacus calculation （MAC） training on children＇s form recognition.Methods 28 children （ 14 children with MAC training and 14 children with non-MAC traning）were investigated by using event-related potential（ERP） technology.The event-related potentials were recorded when subjects were in the different form shape recognition.Results （ 1 ） The amplitudes of the posterior P1 evoked by the children with MAC training （ （9.59 ± 3.58） μV） were significantly greater than that of the children without MAC training （ （7.06 ± 2.84） μV） （ P 〈 0.05 ）.（2） The amplitudes of right temporal-posterior N170 of children with MAC（ （ -9.83 ±2.97） μV） were markedly less than that of children with non-MAC（ （ - 12.45 ±2.51 ） μV） （ P 〈 0.05 ）.（ 3 ） The amplitudes of prefrontal P3 of children with MAC （ （7.65 ± 2.25 ） μV） were remarkably greater than that of children with non-MAC （ （4.89 ± 3.35 ） μV） （ P 〈 0.05 ）.Conclusion The brain function of form recognition in children is influenced by mental abacus calculation training.
