听觉事件相关电位（ERP）是通过平均头皮对重复刺激的电脉冲来获得的。先前的研究表明，儿童、青少年和成人在听觉ERP后期存在巨大差异，这提高了分析波形形状可能作为大脑成熟度指标的可能性。我们重新分析了Albrecht， von Suchodoletz和Uwer（2000）以及Uwer， Albrecht和von Suchodoletz（2002）先前描述的样本中的听觉erp，使用类内相关性（ICC）作为个体波形与每个年龄段的大平均比较波形的相似性的全局度量。三个发育阶段明显区分：5至12岁，13至16岁和成年期。然而，在这些时期中，没有证据表明随着年龄的增长有任何发展进展。
The auditory event-related potential (ERP) is obtained by averaging electrical impulses recorded from the scalp in response to repeated stimuli. Previous work has shown large differences between children, adolescents and adults in the late auditory ERP, raising the possibility that analysis of waveform shape might be useful as an index of brain maturity. We reanalysed auditory ERPs from samples previously described by Albrecht, von Suchodoletz and Uwer (2000) and Uwer, Albrecht and von Suchodoletz (2002), using the intraclass correlation (ICC) as a global measure of similarity of an individual's waveform to a grand average comparison waveform for each age band. Three developmental periods were clearly distinguished: 5 to 12 years, 13 to 16 years, and adulthood. However, within each of these periods, there was no evidence of any developmental progression with age.
