Abstract
A battery of tests of various metalinguistic abilities was administered to children who were good and poor readers and to nonreading adults. The purpose of the study was to discover any such skills that might discriminate purely maturational factors in language acquisition from factors having to do with the development of reading skill. The results suggest that (a) there are no changes in analytical linguistic abilities between the ages of 5 and adulthood in nonreaders, (b) the ability of readers to analyze words phonologically and morphologically appears to be gained during the early years of reading experience, and (c) some syntactic skills previously associated with late cognitive maturation seem to be more causally tied to reading experience.
