Abstract: Objective To explore the impact of abacus calculation on children's perception of the graphic location,to provide the evidence for mental abacus calculation training promoting brain function and mental abacus calculatio teaching. Method A sample of fourteen children trained with abacus mental calculation and fourteen children trained without abacus mental calculation were taken.The brain wave of the children was researched when they judged the graphic location by using the event related potential technique and recorded the amplitude and latent period. Results 1) The difference of the amplitude in two groups' right occipital temporal N170 was significant (F=10.51,P<0.05) and the amplitude of the later was higher.2) The difference of the amplitude of P2 emerging on the forehead was significant (F=5.09,P<0.05) and the data of the children who did not be trained was higher.3) The difference of P3 head latent period was significant (F=9.98,P<0.05) and the latency of the abacus calculation trained children was longer. Conclusion Abacus training has a certain impact on the children's perception of the graphic location.

Key words: children with mental abacus calculation training, spatial location, event-related potential

摘要： 目的 探讨珠心算训练对儿童图形位置知觉的影响,为珠心算开发脑功能和珠心算教学提供依据。方法 以14名珠心算儿童和14名非珠心算儿童为被试,采用事件相关电位技术研究两组儿童在图形位置判断时的脑电变化情况,分别记录不同脑电成分的波幅和潜伏期。结果 1)两组儿童右侧颞枕区N170波幅差异有统计学意义(F=10.51,P<0.05),非珠心算儿童的波幅高于珠心算儿童;2)两组儿童前额P2波幅差异有统计学意义(F=5.09,P<0.05),非珠心算儿童P2波幅显著高于珠心算儿童;3)珠心算儿童顶区P3潜伏期比非珠心算儿童短,差异具有统计学意义(F=9.98,P<0.05)。结论 珠心算训练对儿童图形位置知觉的脑功能有一定影响。
