Event-related potentials (ERPs) were recorded from the left and right temporal and parietal sites during a word naming task. Subjects were a group of children that were followed over four consecutive years starting at Kindergarten. ERP waveforms contained a sequence of positive and negative components (N150, P240, N360, N530 and SW). All components, except N150, showed changes in amplitude as a function of age, whereas SW, N360 and N150 also changed in hemispheric distribution. In addition, a relationship was found between reading performance and ERP amplitudes over the right parietal hemisphere in young children, and over the left temporal hemisphere in older children. Proficient readers showed larger (more negative) parietal N530 amplitudes than less proficient readers, especially when stimuli were degraded words. The results are discussed in terms of age-related changes in right and left hemisphere functions involved in early and advanced stages of reading, that might possibly be related to visual word recognition.
在一项单词命名任务中，从左、右颞叶和顶叶部位记录了事件相关电位（ERP）。研究对象是一组从幼儿园开始连续四年接受跟踪的儿童。ERP波形包含一系列正性和负性成分（N150、P240、N360、N530和SW）。除N150外，所有成分的振幅均随年龄变化，而SW、N360和N150在半球分布上也有变化。此外，还发现幼儿右顶叶半球以及大龄儿童左颞叶半球的ERP振幅与阅读成绩之间存在关联。熟练读者的顶叶N530振幅比不熟练读者更大（更负），尤其是当刺激为变形词时。根据阅读早期和晚期左右半球功能与年龄相关的变化对结果进行了讨论，这些变化可能与视觉单词识别有关。
