The long-term objective of this research program is to examine the development of phonological categories by children with phonological disorders. The specific aims are to characterize the mental representation of phonological categories and to evaluate processing strategies used in categorization by this population. These goals will be accomplished by experimentally testing the course, types, principles, and limits of restructuring in phonological categories by these children. An interdisciplinary research approach is adopted, integrating theories and methodologies of cognitive psychology, linguistics, and speech-language pathology in the study of 72 children' Four main projects are planned, each involving phonological and acoustic descriptions of children's sound systems, assessments of children's judgments of phonological categories, and experimental clinical treatment. Project I examines the course of change in categories by evaluating the hypothesis that certain phonological categories are prerequisite for others in development. Project II differentiates types of change in categories by testing the hypothesis that some phonological changes are easier to induce clinically than others. Project HI takes up the issue of principles governing categories by examining the hypothesis that the degree and extent of clinically-induced change is influenced by a child's predetermined assumptions about the phonological system. Project IV tests the limits of category change by identifying children at risk for no phonological change. The outcome of this research program will contribute to an understanding of phonological categories, development, and change. There is strong applied significance in that the goal of clinical treatment is to induce such change. The findings to emerge will lead to treatment advances for facilitating the greatest change in sound systems. Theoretically, an integrated model of the development of categories as instantiated in the domain of phonology will result. Domain-specific properties of categorization, particular to phonology, will be distinguished from those that are attributable more generally to the cognitive capabilities of learners.

该研究计划的长期目标是检查 儿童的语音类别的发展 疾病。 具体的目的是表征心理 语音类别的表示并评估处理 该人群中使用的策略。 这些目标将 通过实验测试课程，类型，原理， 以及这些语音类别重组的限制 孩子们。 采用了跨学科研究方法， 整合认知心理学的理论和方法论， 在研究72名儿童的研究中的语言学和语言病理学 计划四个主要项目，每个项目涉及语音和声学 对儿童声音系统的描述，儿童的评估 语音类别和实验临床的判断 治疗。 项目我检查了类别变化的过程 评估某些语音类别是 发展中他人的先决条件。 项目II区分类型 通过测试某些语音学的假设，类别变化 比其他人更容易临床诱导变化。 项目嗨 通过检查统治类别的原则问题 假设临床引起的变化的程度和程度是 受孩子对语音的预定假设的影响 系统。 项目IV通过识别类别更改的限制 没有语音变化的孩子。 结果的结果 研究计划将有助于理解语音 类别，开发和变化。 有很强的应用 重要的是，临床治疗的目的是诱导这种 改变。 出现的发现将导致治疗进展 促进声音系统的最大变化。 理论上，一个 实例化的类别开发的综合模型 语音学领域将导致。 域特异性特性 特定于语音的分类将与 那些更普遍地归因于认知能力 学习者。
