A Computer Analysis of Written Language Variables and a Comparison of Compositions Written by University Students with and without Learning Disabilities

Abstract

The utility of computerized analysis of variables cited as predictors of success in written expression was examined. The analysis of compositions written by 423 university students revealed a three-factor structure on 17 variables associated with written expression. A comparison of compositions written by university students with and without learning disabilities was conducted on the three factors identified as vocabulary/fluency, syntactic maturity, and vocabulary/diversity. Students with learning disabilities differed significantly on the factors labeled vocabulary/fluency and syntactic maturity. Students with learning disabilities were not as fluent in word production and in the number of different words used in their compositions as their non-learning-disabled peers. They did, however, produce longer sentences and T-units. The findings of this study suggest that emphasis on the postsecondary level needs to focus on expanding the use of written vocabulary skills, and that the T-unit may not be the best determiner of syntactic complexity at the adult level.
