DEVELOPMENT OF PHONOLOGICAL CATEGORIES

描述：拟议的研究调查了 功能性语音障碍儿童的语音分类。 主要关注的是默认的语言类别， 是声音系统最基本的普遍属性， 所有其他音系范畴的基础。 的 一个基本的假设是，当一个孩子开始 收购过程中与默认以外的普遍，这将有 对随后的声音制作和重组的影响 系统，以至于它实际上可能会阻碍学习，把孩子 面临变革的风险。 两个项目涉及60名3岁至7岁的儿童， 计划检查语言结构不同层次的默认值 与摩擦音中的发音位置有关， 集群 在这两个项目中，将汇集证据， 在习得中的缺省状态，并将包括语音 描述，概念测试，学习模式和计算 分析。 从理论上讲，结果将解决普遍与 默认值的特定于子项的性质， 表示和处理，以及跨 语言结构的层次性。 临床上， 将确定学习的默认值， 在诱导默认值的变化将被建立。

DESCRIPTION: The proposed research investigates the development of phonological categories by children with functional phonological disorders. The primary focus is on default categories of language, which are presumed to be the universal properties most basic to a sound system, and the building blocks from which all other phonological categories emerge. The fundamental hypothesis to be tested is that, when a child initiates the acquisition process with a default other than the universal, this will have repercussions for subsequent elaboration and restructuring of the sound system, so much so that it may actually impede learning and put the child at-risk for change. Two projects involving 60 children, aged 3;0 to 7;6, are planned to examine defaults at different levels of language structure associated with place of articulation in fricatives and with consonant clusters. In both projects, converging evidence will be brought to bear on the status of defaults in acquisition, and will include phonological descriptions, conceptual testing, learning patterns, and computational analyses. Theoretically, the results will address the universal versus child-specific nature of defaults, the convergence of defaults in representation and processing, and the similarity of defaults across hierarchical levels of linguistic structure. Clinically, the consequences of defaults for learning will be determined, and the efficacy of treatment in inducing change in defaults will be established.
