Abstract

Early screening for language problems is a priority given the importance of language for success in school and interpersonal relationships. The paucity of reliable behavioral instruments for this age group prompted the development of a new touchscreen language screener for 2-year-olds that relies on language comprehension. Developmental literature guided selection of age-appropriate markers of language disorder risk that are culturally and dialectally neutral and could be reliably assessed. Items extend beyond products of linguistic knowledge (vocabulary and syntax) and tap the process by which children learn language, also known as fast mapping. After piloting an extensive set of items (139), two phases of testing with over 500 children aged 2; 0–2; 11 were conducted to choose the final 40-item set. Rasch analysis was used to select the best fitting and least redundant items. Norms were created based on 270 children. Sufficient test-retest reliability, Cronbach's alpha, and convergent validity with the MB-CDI and PPVT are reported. This quick behavioral measure of language capabilities could support research studies and facilitate the early detection of language problems.

评估两岁儿童的语言能力:从理论到实践

考虑到语言对学业成功和人际关系的重要性，早期筛查语言问题是一个优先事项。这一年龄段缺乏可靠的行为工具，这促使人们开发了一种新的触摸屏语言筛检器，用于两岁儿童，这种筛检器依赖于语言理解。发展文献指导选择适合年龄的语言障碍风险标记，这些标记在文化和方言上是中立的，并且可以可靠地评估。项目超越了语言知识(词汇和句法)的产物，挖掘了儿童学习语言的过程，也被称为快速映射。在试点了一系列广泛的项目(139)之后，对500多名2岁儿童进行了两个阶段的测试;0 - 2;11人进行了问卷调查，以选出最终的40项问卷。采用Rasch分析法选择最佳拟合项和最少冗余项。规范是根据270名儿童制定的。据报道，MB-CDI和PPVT具有足够的重测信度、Cronbach's alpha和收敛效度。这种对语言能力的快速行为测量可以支持研究并促进语言问题的早期发现。

期刊介绍： Infancy, the official journal of the International Society on Infant Studies, emphasizes the highest quality original research on normal and aberrant infant development during the first two years. Both human and animal research are included. In addition to regular length research articles and brief reports (3000-word maximum), the journal includes solicited target articles along with a series of commentaries; debates, in which different theoretical positions are presented along with a series of commentaries; and thematic collections, a group of three to five reports or summaries of research on the same issue, conducted independently at different laboratories, with invited commentaries.
