Abstract

Limited studies have examined demographic differences in children's vocabulary in longitudinal samples, while there are questions regarding the duration, direction, and magnitude of these effects across development. In this longitudinal study, we included over 400 Dutch children. Caregivers filled out N-CDIs when children were 9-11 months (measuring word comprehension, word production, and gestures) and around 2-5 years of age (measuring word production). At 2-5 years, we also administered a receptive vocabulary task in the lab. We examined demographic effects on vocabulary size across infancy and toddlerhood. We found a disadvantage for males in infants' gestures and toddlers' vocabulary production. We found a negative effect of maternal education on infants' caregiver-reported vocabulary, but a positive effect on toddlers' lab-administered receptive vocabulary. Lastly, we found a negative effect of multilingualism - but only for the lab-administered task. Examining predictors in large, longitudinal samples ensures their robustness and generalisability across development.

研究荷兰儿童在婴儿期和学步期的词汇量：人口统计学效应具有年龄特异性和任务特异性。

对纵向样本中儿童词汇量的人口统计学差异进行的研究有限，而这些影响在整个发展过程中的持续时间、方向和程度也存在问题。在这项纵向研究中，我们纳入了 400 多名荷兰儿童。在儿童 9-11 个月大时（测量词语理解能力、造词能力和手势）和 2-5 岁左右（测量造词能力），照顾者填写了 N-CDI。2-5 岁时，我们还在实验室进行了接受性词汇任务。我们研究了人口统计学对婴儿期和学步期词汇量的影响。我们发现男性在婴儿手势和学步期词汇量方面处于劣势。我们发现，母亲的教育程度对婴儿的照顾者报告词汇量有负面影响，但对幼儿的实验室接受词汇量有正面影响。最后，我们还发现了多语言的负面影响，但仅限于实验操作任务。在大型纵向样本中研究预测因素可确保其在整个发展过程中的稳健性和普遍性。

期刊介绍： A key publication in the field, Journal of Child Language publishes articles on all aspects of the scientific study of language behaviour in children, the principles which underlie it, and the theories which may account for it. The international range of authors and breadth of coverage allow the journal to forge links between many different areas of research including psychology, linguistics, cognitive science and anthropology. This interdisciplinary approach spans a wide range of interests: phonology, phonetics, morphology, syntax, vocabulary, semantics, pragmatics, sociolinguistics, or any other recognised facet of language study.
