在双语儿童语言发展的研究中,早期语言环境的特点通常是根据父母的报告,孩子接触每种语言的相对量。关于两种语言中儿童导向言语的绝对测量与语言发展的关系,人们知之甚少。在这项针对3岁西班牙语-英语双语儿童(n=18)的研究中,将传统的父母报告估计的暴露量与儿童在自然主义录音期间听到的西班牙语和英语单词数量进行了比较。虽然这两个估计值中度相关,但观察到的儿童导向单词数量更一致地预测儿童的处理速度和标准化测试表现,即使在控制报告的暴露比例时也是如此。这些研究结果强调了照顾者参与双语儿童的语言成果的重要性,他们正在学习的两种语言。
In research on language development by bilingual children, the early language environment is commonly characterized in terms of the relative amount of exposure a child gets to each language based on parent report. Little is known about how absolute measures of child‐directed speech in two languages relate to language growth. In this study of 3‐year‐old Spanish‐English bilinguals (n=18), traditional parent‐report estimates of exposure were compared to measures of the number of Spanish and English words children heard during naturalistic audio recordings. While the two estimates were moderately correlated, observed numbers of child‐directed words were more consistently predictive of children's processing speed and standardized test performance, even when controlling for reported proportion of exposure. These findings highlight the importance of caregiver engagement in bilingual children's language outcomes in both of the languages they are learning.
