在10名学龄前语音发育迟缓儿童的临床治疗中，研究了词汇习得年龄（AoA）的影响。使用单受试者多基线实验设计，儿童被招募到四种条件之一中，这些条件改变了治疗单词（早期与晚期获得）相对于其相应单词频率（高频率与低频率）的AoA。语音概括处理和未处理的声音错误作为因变量。结果表明，晚获得的单词诱导更大的概括，效果大小比早获得的单词大四倍，而词频的影响最小化。结果进行了讨论相对于假设的作用，AoA在语言习得和语音学习这个变量的相关性。
The effects of the age of acquisition (AoA) of words were examined in the clinical treatment of 10 preschool children with phonological delays. Using a single-subject multiple-baseline experimental design, children were enrolled in one of four conditions that varied the AoA of the treated words (early vs. late acquired) relative to their corresponding word frequency (high vs. low frequency). Phonological generalization to treated and untreated sounds in error served as the dependent variable. Results showed that late acquired words induced greater generalization, with an effect size four times greater than early acquired words, whereas the effects of word frequency were minimized. Results are discussed relative to hypotheses about the role of AoA in language acquisition and the relevance of this variable for phonological learning.
