This study examines the role of morphological awareness (MA) in literacy achievement and compensation in word reading of adults with dyslexia through an exploration of three questions: (1) Do adult dyslexics demonstrate a deficit in MA, and how is this potential deficit related to phonological awareness (PA)? (2) Does MA contribute independently to literacy skills equally in dyslexics and control readers? and (3) Do MA and PA skills differ in compensated and noncompensated dyslexics? A group of dyslexic and normal reading university students matched for age, education and IQ participated in this study. Group analysis demonstrated an MA deficit in dyslexics; as well, MA was found to significantly predict a greater proportion of word reading and spelling within the dyslexic group compared with the controls. Compensated dyslexics were also found to perform significantly better on the morphological task than noncompensated dyslexics. Additionally, no statistical difference was observed in MA between the normal reading controls and the compensated group (independent of PA and vocabulary). Results suggest that intact and strong MA skills contribute to the achieved compensation of this group of adults with dyslexia. Implications for MA based intervention strategies for people with dyslexia are discussed.
本研究通过探讨三个问题，考察了形态意识（MA）在阅读障碍成年人的读写成就及单词阅读补偿中的作用：（1）成年阅读障碍者是否存在形态意识缺陷，以及这种潜在缺陷与语音意识（PA）有何关系？（2）形态意识在阅读障碍者和对照阅读者中对读写技能的贡献是否相同？（3）在代偿性和非代偿性阅读障碍者中，形态意识和语音意识技能是否存在差异？一组年龄、教育程度和智商相匹配的阅读障碍大学生和正常阅读大学生参与了本研究。组间分析表明阅读障碍者存在形态意识缺陷；此外，与对照组相比，形态意识在阅读障碍组中能显著预测更大比例的单词阅读和拼写。还发现代偿性阅读障碍者在形态任务上的表现明显优于非代偿性阅读障碍者。此外，正常阅读对照组和代偿组在形态意识方面未观察到统计学差异（与语音意识和词汇无关）。结果表明，完整且较强的形态意识技能有助于这组成年阅读障碍者实现代偿。文中还讨论了基于形态意识的阅读障碍干预策略的意义。
