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.

项目总结/摘要音韵学（与语音的模式有关）和形态学（与单词的形成有关）在开发系统时会进行跨语言交互，这种现象被称为形态音系学例如，在英语中，第三人称单数语素-s的发音不同这取决于前面的声音：“eat[s]”vs.“see[z]”vs.“kiss[zh]"。典型发育儿童节目这个语素的准确性不同，这部分是由于周围的语音上下文这项拟议的研究计划将评估形态音系相互作用的影响， 4 - 6岁语音障碍儿童的语言，发育性语言障碍儿童疾病（DLD），以及那些通过操作PD和DLD（PD-DLD）的儿童语音和形态的复杂性在治疗目标词的选择。实验1将评估语音复杂性对语音概括学习的影响， PD和PD-DLD儿童，当目标随形态-语音复杂性而变化时。实验 2将评估DLD和PD-DLD儿童治疗后的语素泛化学习，目标因语音复杂性而异。这项研究将1）将语言学理论与临床处理，以确定跨人群泛化学习的理想目标，2）专注于形态学和音韵学，已知它们在正常系统中相互作用，以及3）定义这些原则如何结合在一起可以告知管理混乱的系统。在拟议工作完成后，将确定这些临床人群内部和之间的形态-语音相互作用，以及形态音系的复杂性在驱动治疗后的变化将被描绘。
