Abstract
This article is based on language, memory andreading information gathered for a five yearfollow-up study of 30 children and adolescentswith Down syndrome, aged from 10 to 24 years atthe end of the study. At Time 1, 10individuals were classified as readers but byTime 2 this number had risen to 16. Readers significantly outperformed non-readerson tests of nonverbal ability, languagecomprehension and production, phonologicalmemory and phonological awarenesss. However,some of these differences could be accountedfor by readers' significantly lower hearingthresholds. Phonological memory and earlyletter knowledge at Time 1 were significantpredictors of reading scores for Time 2readers, after controlling for age, nonverbalability and corresponding Time 1 readingscores. There was no evidence that learning toread had a significant impact on later languagecomprehension, but early reading skills may besignificant predictors of MLU five years later,after controlling for age, nonverbal abilityand hearing.
