在这篇文章中，我们提出了一种新的方法来估计儿童的总词汇量的基础上，在德语的语言语料库。我们从语料库中抽取了一个不同词汇量的虚拟样本，并让虚拟样本通过比较项目是否包含在虚拟词汇中来进行词汇测试。这使我们能够确定测试性能和总词典大小之间的关系。然后，我们将这一关系应用于儿童（1-8年级，6 - 14岁）和年轻人（18 - 25岁）的真实的样本的测试结果，并估计他们的总词汇量。平均绝对词汇量范围从一年级的5900个词元到成人的73，000个词元，除了一年级到二年级之外，相邻年级之间的词汇量显着增加。我们的分析还使我们能够观察词性和形态发展。研究结果为小学阶段词汇的发展提供了理论依据。
In this article we present a new method for estimating children’s total vocabulary size based on a language corpus in German. We drew a virtual sample of different lexicon sizes from a corpus and let the virtual sample “take” a vocabulary test by comparing whether the items were included in the virtual lexicons or not. This enabled us to identify the relation between test performance and total lexicon size. We then applied this relation to the test results of a real sample of children (grades 1–8, aged 6 to 14) and young adults (aged 18 to 25) and estimated their total vocabulary sizes. Average absolute vocabulary sizes ranged from 5900 lemmas in first grade to 73,000 for adults, with significant increases between adjacent grade levels except from first to second grade. Our analyses also allowed us to observe parts of speech and morphological development. Results thus shed light on the course of vocabulary development during primary school.
