In a simple prime-target auditory rhyming event-related potential (ERP) paradigm with adults and 6-, 7-, and 8-year-old children, nonword stimuli (e.g., nin-rin, ked-voo) were used to investigate neurocognitive systems involved in rhyming and their development across the early school years. Even absent semantic content, the typical CNV to primes and late rhyming effect (RE) to targets were evident in all age groups. The RE consisted of a more negative response to nonrhyming targets as compared to rhyming targets over posterior sites, with a reversal of this pattern at lateral anterior sites. The hypothesis that the CNV indexes phonological memory processes was not well supported by correlation analyses conducted with the ERP measures and scores on standardized behavioral tests. However, the onset of the rhyming effect was later in those scoring lower on phonological awareness measures.
在一个针对成人以及6岁、7岁和8岁儿童的简单的质数-目标听觉押韵事件相关电位（ERP）范式中，使用非单词刺激（例如，nin-rin、ked-voo）来研究参与押韵的神经认知系统及其在小学早期阶段的发展。即使没有语义内容，所有年龄组中对质数的典型关联性负变（CNV）和对目标的晚期押韵效应（RE）都是明显的。RE表现为与押韵目标相比，在后部位点对非押韵目标有更负向的反应，而在外侧前部位点这种模式则相反。用ERP测量值和标准化行为测试分数进行的相关性分析并未很好地支持CNV指标语音记忆过程这一假设。然而，在语音意识测量中得分较低的那些人，押韵效应的起始时间较晚。
