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。 主要的关注点是默认的语言类别，这是假定的 是音响系统最基本的普遍属性，而 构成所有其他音系类别的积木。这个 需要检验的基本假设是，当一个孩子发起 收购过程中默认不是通用的，这会有 对后来对声音的阐述和重组的影响 太多了，以至于它实际上可能会阻碍学习，让孩子 面临变革的风险。两个项目，涉及60名儿童，年龄为3岁；0至7岁；6， 计划检查不同语言结构级别的默认设置 与摩擦音中的发音位置和辅音相关 集群。在这两个项目中，都将利用趋同的证据 习得中的默认状态，将包括音位 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 特定于子对象的默认性质，默认值在 表示和处理，以及缺省值的相似性 语言结构的层级。在临床上，其后果是 学习的缺省情况将被确定，并治疗的效果 在促使违约发生变化的过程中，将建立违约机制。

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.
