LEXICAL AND SYNTACTIC DEVELOPMENT IN INFANCY

目前对中国的语言发展知之甚少。 语言前的婴儿和幼儿。然而，研究表明 证明婴儿确实在第一次学习他们的语言 几个月，特别是在语言的发音结构方面。 这里提出的研究的第一个目标是评估哪些元素 婴儿通过一般的心理学习来学习语言 利用婴儿在他们周围听到的语言的机制。这将是 通过对年轻人讲话语料库的计算建模来完成 儿童，并通过婴儿的知觉实验。第二个目标 这项研究的目的是创建一种能够评估个人的程序 儿童对单词的准确记忆的发展。此程序将 然后被用来调查儿童之间可能的变异来源 词汇学习中的词汇表征与理解效率 演讲。对一岁婴儿的纵向研究将检查 成人型词汇的发展，以及为什么个别婴儿可能 在早期的语言学习中有所不同。

At present very little is known about language development in prelinguistic infants and young children. However, research has demonstrated that infants do learn about their language over the first several months ,particularly in terms of the language's sound structure. The first goal of the research proposed here is to assess what elements of language are learned by infants using general psychological learning mechanisms capitalizing on the speech infants hear around them. This will be done through computational modeling of corpora of speech to young children, and through perceptual experiments with infants. The second goal of the research is to create a procedure capable of assessing individual children's development of accurate memory for words. This procedure will then be used to investigate possible sources of variation between children in word learning, word representation, and efficiency in understanding speech. Longitudinal studies of one-year-old infants will examine the development of adult like forms of words, and why individual infants may differ in early language learning.
