Multisyllabic words constitute a large portion of children's vocabulary. However, the relationship between phonological neighborhood density and English multisyllabic word learning is poorly understood. We examine this link in three, four and six year old children using a corpus-based approach. While we were able to replicate the well-accepted positive association between CVC word acquisition and neighborhood density, no similar relationship was found for multisyllabic words, despite testing multiple novel neighborhood measures. This finding raises the intriguing possibility that phonological organization of the mental lexicon may play a fundamentally different role in the acquisition of more complex words.
多音节词在儿童词汇中占很大一部分。然而，语音邻域密度与英语多音节词学习之间的关系却鲜为人知。我们采用基于语料库的方法，对三岁、四岁和六岁的儿童进行了研究。虽然我们能够重现广为人知的CVC词习得与邻域密度之间的正相关关系，但尽管测试了多种新颖的邻域测量方法，多音节词却未发现类似关系。这一发现引发了一个有趣的可能性，即心理词库的语音组织在更复杂词汇的习得中可能发挥着根本不同的作用。
