项目摘要

Project Summary/Abstract The first two years of a child’s life are marked by an increasing ability to learn new words and an exponential growth in their vocabulary. We also know that the context in which a child learns a new word affects the integration of that word into their lexicon and has cascading effects on language growth over time. However, the last decade has seen a rise in digital media as a source of language input, marking a shift in the contexts in which children encounter and learn words – from rich, three- dimensional, and interactive objects to moments that are less rich, less embodied, and more transient. Little, however, is known about how children map, retain, and generalize words in digital forms or the cascading impact digital media has on vocabulary growth. The goal of the current proposal is to identify how digital media alters the mechanisms of word learning and subsequently impacts the lexical foundation on which a child’s vocabulary is built. Specifically, the proposal aims to identify the impact of digital media on 1) the processes underlying real-time word learning, and 2) the processes of language generalization and vocabulary growth. Specific Aim 1 will use a novel word learning task to test children’s ability to map and retain new words within and between digital media (2D images on a tablet) and real world objects (3D objects). Specific Aim 2 will probe children’s novel label generalization abilities within and between 2D and 3D modalities using a novel noun generalization task. Further, individual differences in a child’s prior technology experience will be measured and used to predict overall vocabulary as well as performance within and between each task. The results will advance our understanding of language development by a) establishing whether the process of word learning from digital media qualitatively differs from learning with real objects, and b) quantifying how digital contexts alter the cascade by which lexical development supports vocabulary growth. Further, the findings will have implications for predicting long-term language outcomes and forming specific recommendations (or warnings) for educators, clinicians, and parents on when and how young children’s technology exposure impacts word learning during these critical years.

项目概要/摘要孩子生命的头两年的特点是学习新单词的能力不断增强，并且他们的词汇量呈指数级增长。我们还知道，孩子学习新事物的环境单词会影响该单词与词汇的整合，并对语言的发展产生连锁效应随着时间的推移。然而，过去十年，数字媒体作为语言输入来源的兴起，标志着孩子们遇到和学习单词的环境发生了转变——从丰富的、三- 维度和交互对象变成了不那么丰富、不那么具体、更短暂的时刻。然而，人们对儿童如何以数字形式或数字形式映射、保留和概括单词却知之甚少。数字媒体对词汇量增长的连锁影响。当前提案的目标是确定数字媒体如何改变单词学习的机制并随后影响词汇孩子词汇量的基础。具体来说，该提案旨在确定影响数字媒体的 1) 实时单词学习的过程，以及 2) language generalization and vocabulary growth.具体目标 1 将使用新颖的单词学习任务来测试儿童在数字媒体内部和之间映射和保留新单词的能力（2D 图像）平板电脑）和现实世界对象（3D 对象）。《Specific Aim 2》将探讨儿童小说的标签使用新颖的名词泛化在 2D 和 3D 模态内部和之间的泛化能力任务。此外，将测量和使用儿童先前技术经验的个体差异预测总体词汇量以及每个任务内和之间的表现。结果将通过以下方式增进我们对语言发展的理解：a）确定词的过程是否从数字媒体中学习与从真实物体中学习在本质上是不同的，并且 b) 量化如何数字环境改变了词汇发展支持词汇增长的级联。更远，研究结果将对预测长期语言结果和形成具体的语言结果产生影响向教育工作者、临床医生和家长提供有关何时以及如何年轻的建议（或警告）儿童在这些关键时期的科技接触会影响单词学习。
