Morphological Awareness Predicts Reading Comprehension in Adults

Abstract

We investigated the contribution of morphological awareness to university students’ reading comprehension ability. Although there is considerable evidence that morphological awareness contributes to children’s reading ability, there is much less evidence concerning adults; the few studies of adults have not controlled other known predictors of reading comprehension. Furthermore, there is little information about the predictors of morphological awareness. Measures related to word reading (phonological decoding, orthographic processing), language comprehension (vocabulary, inferences, working memory), morphological awareness, and reading (reading speed and reading comprehension) were administered to 71 undergraduate students. Hierarchical regression analyses indicated that (a) morphological awareness was predicted by orthographic processing and the three language comprehension measures, (b) morphological awareness was a significant predictor of both reading speed and reading comprehension, after controlling all of the other predictors, and (c) morphological awareness continued to predict reading comprehension after also controlling text reading speed. These results demonstrate that morphological awareness is still an important individual difference factor for proficient adult readers. We discuss the implications of these results for assessment and university instruction.
