项目摘要

PROJECT SUMMARY/ABSTRACT Phonology (relating to the patterning of speech sounds) and morphology (relating to the formation of words) are known to interact cross-linguistically and in developing systems, and this phenomenon is referred to as morpho-phonology. For example, in English, the third-person singular morpheme -s is pronounced differently depending on the preceding sound: “eat[s]” vs. “see[z]” vs. “kiss[ɪz]”. Typically-developing children show differing levels of accuracy on this morpheme, and this is attributable in part to the surrounding phonological context. This proposed research program will evaluate the influence of morpho-phonological interaction in the language of children aged 4 to 6 years with phonological disorder (PD), those with developmental language disorder (DLD), and those children with co-occurring PD and DLD (PD-DLD) through manipulation of phonological and morphological complexity in the selection of treatment target words. Experiment 1 will evaluate effects of phonological complexity on speech-sound generalization learning following treatment of children with PD and PD-DLD when targets vary with respect to morpho-phonological complexity. Experiment 2 will evaluate morpheme generalization learning following treatment of children with DLD and PD-DLD when targets vary by phonological complexity. The proposed research will 1) bridge linguistic theory with clinical treatment to identify ideal targets for generalization learning across populations, 2) focus on both morphology and phonology, which are known to interact in normal systems, and 3) define how these principles together can inform the management of disordered systems. Upon completion of the proposed work, the nature of morpho-phonological interactions within and across these clinical populations will be identified, and the role of morpho-phonological complexity in driving change following treatment will be delineated.

项目摘要/摘要语音学（与语音的模式有关）和形态（与单词的形成有关）已知会在跨语言和开发系统中相互作用，这种现象被称为形态表达。例如，用英语，第三人称奇异词素-s的发音不同根据前面的声音：“饮食”与“见z”和“ kiss [ɪZ]”。通常会发育的孩子表现出来该词素上的准确性不同，这部分归因于周围的语音学语境。该提出的研究计划将评估形态表相互作用在 4至6岁儿童语言障碍（PD）的语言，有发育语言的语言障碍（DLD），以及通过操纵患有同时发生PD和DLD（PD-DLD）的孩子选择治疗目标单词的语音和形态复杂性。实验1将评估语音复杂性对处理后语音概括学习的影响当目标因形态学复杂性而变化时，患有PD和PD-DLD的儿童。实验 2将在治疗DLD和PD-DLD儿童后评估词素概括性学习目标因语音复杂性而异。拟议的研究将1）用临床桥接语言理论治疗以识别跨种群概括学习的理想目标，2）专注于两种形态和语音学，已知可以在正常系统中相互作用，以及3）定义这些原理如何一起可以告知无序系统的管理。拟议的工作完成后，将确定这些临床人群内外的形态表达相互作用，以及将描绘出在处理后驱动变化方面的形态表达复杂性。
