The present study examined developmental differences in event-related potentials between second graders and adults in arithmetic. Consistent with previous literature in adults, multiplication for both children and adults produced a greater left anterior negativity from 400 to 900 msec, whereas addition produced a greater right posterior negativity from 400 to 900 msec. Adults showed larger left anterior negativities in the time window suggesting that adults rely more than children on a verbal processing system for solving these problems. Children showed larger right posterior negativities in the time window suggesting that they rely more on quantitative manipulation for solving these problems.
本研究考察了二年级学生与成年人在算术运算中事件相关电位的发展差异。与先前关于成年人的文献一致，儿童和成年人在乘法运算中，在400至900毫秒期间均产生更大的左前负波，而加法运算在400至900毫秒期间产生更大的右后负波。成年人在该时间窗口显示出更大的左前负波，这表明成年人在解决这些问题时比儿童更依赖言语加工系统。儿童在该时间窗口显示出更大的右后负波，这表明他们在解决这些问题时更依赖数量操作。
