In this study, the authors compared the morphological awareness abilities of children with speech sound disorder (SSD) and children with typical speech skills and examined how morphological awareness ability predicted word-level reading and spelling performance above other known contributors to literacy development.
Eighty-eight first-grade students--44 students with SSD and no known history of language deficiencies, and 44 students with typical speech and language skills--completed an assessment battery designed to measure speech sound production, morphological awareness, phonemic awareness, letter-name knowledge, receptive vocabulary, word-level reading, and spelling abilities.
The children with SSD scored significantly lower than did their counterparts on the morphological awareness measures as well as on phonemic awareness, word-level reading, and spelling tasks. Regression analyses suggested that morphological awareness predicted significant unique variance on the spelling measure for both groups and on the word-level reading measure for the children with typical skills.
These results suggest that children with SSD may present with a general linguistic awareness insufficiency, which puts them at risk for difficulties with literacy and literacy-related tasks.
本研究中，作者比较了语音障碍（SSD）儿童和具有典型言语技能儿童的形态意识能力，并考察了形态意识能力如何在其他已知的读写发展贡献因素之上预测单词水平的阅读和拼写表现。
88 名一年级学生——44 名有 SSD 且无已知语言缺陷的学生，以及 44 名具有典型言语和语言技能的学生——完成了一个评估工具包，旨在测量语音产生、形态意识、音韵意识、字母名称知识、接受性词汇、单词水平阅读和拼写能力。
SSD 儿童在形态意识测量以及音韵意识、单词水平阅读和拼写任务上的得分明显低于对照组。回归分析表明，对于两个组，形态意识预测了拼写测量的显著独特差异，对于具有典型技能的儿童，形态意识预测了单词水平阅读测量的显著独特差异。
这些结果表明，SSD 儿童可能表现出一般的语言意识不足，这使他们面临读写和读写相关任务的困难的风险。
