Event-related potentials (ERPs) and behavioral accuracy judgments were recorded in a letter name rhyming paradigm (e.g., A-J versus A-B) with 6- to 8-year-old beginning readers and adults. A typical N450 rhyming effect was evident for both children and adults, with few differences in mean amplitude or peak latency between groups. The size and timing of the electrophysiological effect were not correlated with standardized measures of phonological or reading ability, but accuracy in the ERP task was. Single letters elicit a similar ERP rhyming effect in young children and adults, suggesting the early establishment of neurocognitive systems used in the rhyme task.
在一项字母名称押韵范式（例如，A-J 与 A-B）中，对 6 至 8 岁的初读者和成年人记录了事件相关电位（ERP）和行为准确性判断。儿童和成年人都出现了典型的 N450 押韵效应，两组之间的平均振幅或峰值潜伏期几乎没有差异。电生理效应的大小和时间与语音或阅读能力的标准化测量无关，但与 ERP 任务中的准确性相关。单个字母在幼儿和成年人中引发了类似的 ERP 押韵效应，这表明在押韵任务中使用的神经认知系统已早期建立。
