DESCRIPTION (provided by applicant): The long-term goals are to understand how preschool children with functional (nonorganic) phonological delays acquire the sound system of language, and to identify the factors that accelerate phonological learning in clinical treatment. The specific aim of the proposed research is to extend models of spoken word recognition to the study of phonological learning in testing the hypothesis that the structure of words differentially affects children's acquisition of speech sounds. Project 1 evaluates the acquisition of novel (non)words as an apparent jumpstart to phonological learning. Project 2 assesses the effects of long-term priming as a potential learning mechanism that accelerates phonological learning. The planned studies utilize experimental single-subject design to induce phonological generalization in treatment, with the translational mission of improved efficacy of clinical practice. The theoretical contributions are to psycholinguistic and developmental theories in elaborating the effects of the statistical regularities of language on the acquisition process as realized in a population of children with atypical linguistic development. PUBLIC HEALTH RELEVANCE::The proposed research focuses on the success of clinical treatment for preschool children who have been diagnosed with speech sound delays with no known origin. The goal is to identify the treatment variables that will help children to learn and correctly produce speech sounds. Two treatment factors will be tested: (1) the kinds of words that are taught and (2) the methods of word presentation.

描述（申请人提供）：长期目标是了解有功能性（非器质性）语音延迟的学龄前儿童如何习得语言的声音系统，并在临床治疗中确定加速语音学习的因素。本研究的具体目的是将口语单词识别模型扩展到语音学习的研究中，以检验单词结构差异影响儿童语音习得的假设。项目1评估新（非）单词的习得作为语音学习的明显开端。项目2评估长期启动作为一种加速语音学习的潜在学习机制的影响。计划的研究采用实验性单受试者设计，诱导治疗中的语音泛化，以提高临床实践的疗效为转化使命。理论的贡献是心理语言学和发展理论，阐述了语言的统计规律对非典型语言发展儿童群体习得过程的影响。公共卫生相关性：*拟议的研究侧重于临床治疗被诊断患有不明原因的语音延迟的学龄前儿童的成功情况。目标是确定治疗变量，这将有助于儿童学习和正确地发出语音。将测试两个治疗因素：(1)教授的单词种类和(2)单词呈现的方法。
