Abstract
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. Key words: Mental abacus calculation training; Form recognition; Event-related potential; Children
