加倍：英国双语和单语幼儿的词汇量比较

我们使用家长报告的词汇问卷，比较了在英国（UK）长大的双语幼儿和年龄匹配的英国英语单语者（12-36个月大）在理解和生产方面的词汇量。我们发现双语幼儿的英语词汇量小于单语幼儿的词汇量。值得注意的是，这种词汇差距并没有发现时，组之间的概念词汇的理解。概念评分也缩小了产出中的词汇差距，但组间差异仍然显着。当两种语言的单词加在一起时，双语幼儿比单语幼儿知道更多的单词，无论是理解还是生产。这一巨大的总词汇量可以归因于双语者词汇中高比例的成对词（具有相同含义的跨语言词对）。这些研究结果进行了讨论，语言暴露，促进跨语言的重叠和成熟的词汇量的限制。
We compared vocabulary sizes in comprehension and production between bilingual toddlers growing up in the United Kingdom (UK) and age‐matched UK English monolinguals (12–36 months old) using parent‐report vocabulary questionnaires. We found that bilingual toddlers' vocabulary sizes in English were smaller than the vocabulary sizes of their monolingual peers. Notably, this vocabulary gap was not found when groups were compared on conceptual vocabulary in comprehension. Conceptual scoring also reduced the vocabulary gap in production but group differences were still significant. Bilingual toddlers knew more words than monolinguals when words across their two languages were added together, for both comprehension and production. This large total vocabulary size could be attributed to a high proportion of doublets (cross‐linguistic word pairs with the same meaning) in bilinguals' vocabularies. These findings are discussed in relation to language exposure, facilitation from cross‐linguistic overlap and maturation constraints on vocabulary size.
