The Cross-linguistic Lexical Task (CLT; Haman, Łuniewska & Pomiechowska, 2015) is a vocabulary task designed to enable cross-linguistic comparisons both across and within (bilingual) children. In this paper we assessed the validity of the CLT as a measure of language proficiency in bilingual children, by determining the extent to which (i) age-matched, monolingual Spanish-speaking and Dutch-speaking children obtained similar scores, (ii) the CLT correlated with other measures of language proficiency in monolingual and bilingual children, and (iii) whether the factors underlying the CLT's construction, i.e., target words’ estimated Age of Acquisition and Complexity Index, were predictive of children's scores. Our results showed that, while the CLT correlated with other measures and is therefore a valid means of tapping into language proficiency, caution is required when using it to compare children's language proficiency cross-linguistically, as scores for Dutch-speaking and Spanish-speaking monolinguals sometimes differed.

测试跨语言词汇任务的有效性作为双语儿童语言能力的衡量标准

跨语言词汇任务 (CLT; Haman, Łuniewska & Pomiechowska, 2015) 是一项词汇任务，旨在实现跨（双语）儿童之间和内部的跨语言比较。在本文中，我们评估了 CLT 作为双语儿童语言能力衡量标准的有效性，通过确定 (i) 年龄匹配、单语西班牙语和荷兰语儿童获得相似分数的程度，(ii) CLT 与单语和双语儿童语言能力的其他测量值相关，以及 (iii) CLT 构建的基础因素，即目标词的估计年龄和复杂性指数，是否可以预测儿童的分数。我们的结果表明，
