STUTTERING AND DISORDERED PHONOLOGY IN YOUNG CHILDREN

描述：（改编自申请人摘要）主要目的 这个项目的目的是研究口吃和 幼儿的语音障碍。 据推测， 口吃但语音发育正常的人：（1）口吃 由于话音速率性能和话音速率之间的不一致 能力;和（2）证据声音/音节重复包含适当的 CV或VC转换。 相比之下，口吃的孩子， 语音障碍并存：（1）口吃，因为困难 控制、正确地产生和稳定言语;（2）证据 声音/音节重复，CV或VC缺失或不适当 过渡。 受试者将是120名3-7岁的儿童，在四个 年龄和性别匹配的口吃者和非口吃者组， 没有同时存在的语音障碍。 听觉和感知数据 从孩子们与母亲的交谈和命名的录音中 将用图片回答以下问题：（1）做四个 不同的组在说话和/或diadochokinetic率？ (2)做四个 不同的组在过程中丢失或不适当的过渡的频率不同， 声音/音节重复和/或启动声音发声的能力 什么？ (3)这两组口吃者的频率是否不同， 声音/音节和/或单音节单词重复或百分比 口吃是一种发音上的障碍吗 （4）统计 言语和舒张运动速率、频率/性质之间的关系 语音不流利，正确发音的百分比以及 频率和性质的语音过程中证明了这四个 团体？ 研究结果旨在：（1）澄清 儿童语音障碍和口吃;（2）查明因素 导致正常和有障碍的儿童口吃 语音;（3）识别儿童的知觉和声学指标 “非典型”和“典型”的不流利，以及有前途的领域， 临床管理

DESCRIPTION: (Adapted From The Applicant's Abstract) The primary objective of this project is to study the co-occurrence of stuttering and phonological disorders in young children. It is hypothesized that children who stutter but evidence normal phonological development: (1) stutter because of a disparity between speech rate performance and speech rate ability; and (2) evidence sound/syllable repetitions containing appropriate CV or VC transitions. In contrast, children who stutter and have co-existing phonological disorders: (1) stutter because of difficulties controlling, correctly producing and stabilizing speech; and (2) evidence sound/syllable repetitions with missing or inappropriate CV or VC transitions. Subjects will be 120 children, 3-7 years of age, in four age-and sex-matched groups of stutterers and nonstutterers, with and without co-existing phonological disorders. Acoustic and perceptual data from recordings of the children conversing with their mothers and naming pictures will be used to answer the following questions: (1) do the four groups differ in speaking and/or diadochokinetic rate? (2) do the four groups differ in frequency of missing or inappropriate transitions during sound/syllable repetitions and/or ability to initiate phonation of sound prolongations? (3) do the two groups of stutterers differ in frequency of sound/syllable and/or monosyllabic word repetitions or in percentage of stutterings that are sound prolongations? and (4) are there statistical relationships between speech and diadochokinetic rates, frequency/nature of speech disfluencies, percentage of sounds produced correctly and the frequency and nature of the phonological processes evidenced among the four groups? Findings are intended to: (1) clarify relationships between disordered phonology and stuttering in children; (2) pinpoint factors contributing to stuttering of children with normal and disordered phonology; and (3) identify perceptual and acoustic indexes of children's "atypical" and "typical" disfluencies as well as promising areas of clinical management.
