Auditory evoked potential-age (AEP-age) is proposed to index auditory maturation and has been found to predict language skills in children with and without a language disorder. However, reporting average effects using linear regression does not fully capitalize on the potential of AEP-age to estimate individual differences in young children. This study used a quantile regression approach to examine the predictive utility of AEP-age for 105 typical and neurodiverse 7-10-year-old children (61 males; 44 females; largely monolingual English) with varying language skills without creating subgroups. Although linear regression did not find an association between AEP-age and language skills, the quantile model added specificity by revealing differential associations. AEP-age was only related to language skills for children at around the median point of the language continuum, but, not for those at the lowest or highest end of the language distribution. Overall, the quantile regression methodology provides us with the flexibility of understanding how AEP-age is related to different language abilities.
听觉诱发电位年龄（AEP-age）被提议作为听觉成熟度的指标，并且已发现它能预测有或没有语言障碍儿童的语言技能。然而，使用线性回归报告平均效应并不能充分利用AEP-age来估计幼儿个体差异的潜力。本研究采用分位数回归方法，在不创建亚组的情况下，检验了AEP-age对105名7至10岁具有不同语言技能的典型儿童和神经发育异常儿童（61名男性；44名女性；主要为单语英语使用者）的预测效用。尽管线性回归未发现AEP-age与语言技能之间存在关联，但分位数模型通过揭示差异关联增加了特异性。AEP-age仅与处于语言连续体中位数点左右的儿童的语言技能相关，而与处于语言分布最低或最高端的儿童无关。总体而言，分位数回归方法为我们提供了灵活性，使我们能够理解AEP-age与不同语言能力之间的关系。
