DESCRIPTION (provided by applicant): A hallmark of early phonological development is the presence of both inter- and intra-word variability, phenomena that traditional linguistic theories often have difficulty accounting for. Recent evidence suggests that observed variability may be systematically influenced by lexical development. The overall objective of this project is to investigate lexical-phonological interactions in development. Specifically, the lexical characteristics of word frequency (WF), neighborhood density (ND), and age-of-acquisition (AOA) will be studied in relation to the accuracy and variability of single word productions by typically developing toddlers. The project will consist of a longitudinal transcription-based investigation (19-29 months) of production accuracy and variability in relation to the variables of WF, ND, and ADA. The theoretical framework adopted is that of Usage-based phonology which emphasizes the role of language use in the construction of a phonological system. The results of this study will enhance our understanding of lexicalphonological interactions in typical development, which may in turn help us to better understand the nature of phonological deficits and will inform our decisions regarding appropriate treatment methods and targets.

描述（由申请人提供）：早期语音发展的一个标志是词间和词内变异的存在，传统语言理论通常难以解释这种现象。最近的证据表明，观察到的变异性可能会受到词汇发展的系统影响。该项目的总体目标是研究发展中的词汇语音相互作用。具体来说，将研究典型发育幼儿的词频（WF）、邻域密度（ND）和习得年龄（AOA）的词汇特征与单个词产生的准确性和可变性的关系。该项目将包括对 WF、ND 和 ADA 变量相关的生产准确性和变异性进行纵向转录调查（19-29 个月）。采用的理论框架是基于用法的音系学，强调语言使用在音系系统构建中的作用。这项研究的结果将增强我们对典型发展中词汇语音相互作用的理解，这反过来可能有助于我们更好地理解语音缺陷的本质，并为我们决定适当的治疗方法和目标提供信息。
