Reading and writing development: report from an ongoing longitudinal study of language-disordered and normal groups...

This interim report provides information on an ongoing longitudinal study of 115 subjects, 78 language-disordered children and 39 children with no known language disorders as a control group. This follow-up study reports on a subgroup of the original subjects, 90 adolescents who completed a questionnaire, and 48 of the 90 who have been administered a full test battery compiled by the authors. Ongoing analyses indicate that early language problems are slow to resolve, persisting in one linguistic form or another in these adolescents who are now age 18 and about to leave school.
