Core vocabulary lists are frequently used to select vocabulary for early symbolic communicators who require augmentative and alternative communication (AAC). The current study extended existing work by investigating how core vocabulary lists overlap and diverge from typical language development.
We investigated when the words on seven core vocabulary lists emerge in typical language development, the composition of the lists based on their parts of speech, and how the composition of the words on the lists compare to the MacArthur Bates Communication Development Inventories (CDI).
On average, the words on the seven core vocabulary lists appear after the second year of life in children with typical spoken language development (25, 27, 37, 45, 47, 50, and 66 months). Verbs were the most prevalent part of speech in all but one of the core vocabulary lists. Core vocabulary words made up only a small percentage of words on the CDI.
The words on the core vocabulary lists do not emerge until later points in typical lexical development. Focussing on core words when working with early symbolic communicators who require AAC may lead to limited and variable lexicons with wide gaps.
核心词汇列表常用于选择需要辅助沟通（AAC）的早期象征性沟通者的词汇。本研究通过调查核心词汇列表与典型语言发展的重叠和分歧，扩展了现有工作。
我们研究了七个核心词汇列表中的单词在典型语言发展中何时出现，基于其词性的列表组成，以及列表中单词的组成与麦克阿瑟·贝茨沟通发展量表（CDI）的比较。
在具有典型口语语言发展的儿童中，七个核心词汇列表中的单词平均在 25、27、37、45、47、50 和 66 个月后出现。除一个列表外，动词在所有核心词汇列表中都是最常见的词性。核心词汇单词仅占 CDI 单词的一小部分。
核心词汇列表中的单词直到典型词汇发展的后期才会出现。在与需要 AAC 的早期象征性沟通者一起工作时，专注于核心单词可能会导致词汇量有限且变化，并且存在很大的差距。
