珠心算训练儿童加法心算的ERP早成分研究

采用事件相关电位(ERP)的方法,对32名儿童进行了双位数加法心算实验,探讨了珠心算训练方式对儿童加法心算加工早期感知觉的影响。研究结果表明,与非珠心算训练儿童相比,在加法心算过程的早期阶段,珠心算训练儿童枕部P1、额中央区的N1波幅增大,而颞枕区N170以及额中央区P2波幅减小。本研究结果发现珠心算训练对儿童心算过程的早期感知有显著影响。

The Research of ERPs on the Early Process of Additive Mental Calculation by Mental Abacus Calculation Children

To explore the influence of mental abacus calculation training on children's early perception of additive mental calculation,32 children were investigated through two digit additive mental calculation by event related potentials (ERPs) technology.The results showed that the amplitudes of the posterior P1 and central prefront al N1 evoked by the children with mental abacus calculation training were larger than that of the children without mental abacus calculation training,but the amplitudes of temporal posterior N170 and central prefrontal P2 were smaller than that of the children without mental abacus calculation training in the early stag of additive mental calculation.It was indicated that the early percep tion of children in the mental calculation process was influenced by mental abacus calculation training.
