项目摘要

DESCRIPTION (provided by applicant): This program considers the roles of complexity and of variability in sound error patterns and their possible interaction in the treatment of children with speech disorders. Complexity is appealed to as a universal property of language, defined here in terms of markedness. Based on previous treatment efficacy research, it is predicted that greater improvements will occur following treatment on more complex aspects of the sound system than on less complex sounds. The first goal of this project is to further evaluate the role of complexity in effecting change in children's sound systems. Variability is appealed to in terms of the number, extent, and type of errors that a child produces for a given target English sound. Based on previous research, it is predicted that greater gains will result from treatment on sounds that are produced more variably than on those produced less variably. Because no previous research has experimentally evaluated this prediction, the second goal of this project is to consider the role of variability in promoting change in children's sound systems. As of yet, no research has evaluated how complexity interacts with other variables for treatment sound selection. Because sounds that are complex can also be produced variably or non-variably, the third goal of this project is to experimentally evaluate the interaction between complexity and variability by determining the combined effects of the two variables on children's sound systems. Eighteen monolingual English-speaking children with speech disorders will participate, with each assigned to 2 combined treatment conditions based on variability and complexity. These conditions will be evaluated separately and in conjunction with one another. The results of this project will provide guidelines for effective treatment of speech disorders, and they will help in determining the additive (or precedence) relationships between different types of variability and relative complexity. Theoretically, the results will aid in establishing specific aspects of sound systems that contribute most to speech sound development.

描述（由申请人提供）：该程序考虑了复杂性和声音错误模式的可变性及其在言语障碍儿童治疗中的可能相互作用。复杂性被作为语言的普遍特性吸引，此处定义为标志性。基于先前的治疗效果研究，可以预测，在声音系统更复杂的方面，将在声音更复杂的方面进行更大的改善。该项目的第一个目标是进一步评估复杂性在影响儿童音响系统变化中的作用。从给定的目标英语声音产生的错误的数量，程度和类型的错误，对可变性有吸引力。基于先前的研究，可以预测，与产生的声音相比，产生的声音的处理将带来更大的收益，而这种声音比产生的声音更可变化。由于以前没有研究对这一预测进行了实验评估，因此该项目的第二个目标是考虑变异性在促进儿童音响系统变化中的作用。到目前为止，尚无研究评估复杂性如何与其他变量相互作用进行治疗选择。由于复杂的声音也可以多样化或不变产生，因此该项目的第三个目标是通过确定两个变量对儿童声音系统的综合效应来实验评估复杂性和可变性之间的相互作用。有18个单语英语的语音障碍儿童将参加，每个儿童都根据可变性和复杂性分配给2个组合治疗条件。这些条件将分别评估并彼此结合。该项目的结果将为有效治疗语音疾病提供指南，它们将有助于确定不同类型的可变性和相对复杂性之间的添加剂（或优先级）关系。从理论上讲，结果将有助于建立声音系统的特定方面，从而为语音发育做出最大的贡献。
