在一个简单的听觉押韵范式中，需要对每个口头刺激对的第二个词（目标）做出按钮按下反应（押韵非押韵），ERP 波形的早期（P50、N120、P200、N240）和晚期（CNV、N400、P300）分量都证明了从童年中期到成年的相当大的变化。此外，行为准确性和反应时间随着年龄的增长而提高。相比之下，从 7 岁到成年，几种押韵效应（包括后 N400 押韵效应、左半球前押韵效应以及对 P50 潜伏期、N120 潜伏期和 P200 振幅的早期押韵效应）中每一种的大小、分布和潜伏期保持恒定。 7岁。
In a simple auditory rhyming paradigm requiring a button-press response (rhymelnonrhyme) to the second word (target) of each spoken stimulus pair, both the early (P50, N120, P200, N240) anti late (CNV, N400, P300) components of the ERP waveform evidenced considerable change from middle childhood to adulthood. In addition, behavioral accuracy and reaction time improved with increasing age. In contrast, the size, distribution and latency of each of several rhyming effects (including the posterior N400 rhyming effect, a left hemisphere anterior rhyming effect, and early rhyming effects on P50 latency, N120 latency and P200 amplitude) remained constant from age 7 to adulthood These results indicate that the neurocognitive networks involved in processing auditory rhyme information, as indexed by the present task, are well established and have an adult-like organization at least by the age of 7.
