Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Children with language-learning disabilities (LLD) have language and reading skills that are weaker than those of typically developing children. In the school-age years, reading is a primary means of exposure to new vocabulary for typically developing children. Although these children would not be expected to master a new word through a single exposure to it in text, children show evidence of partial word knowledge growth (e.g., Wagovich \& Newhoff, 2004). The purpose of this project is to characterize the partial word knowledge growth of children with LLD, in comparison to children with typical language skills. Five forms of partial word knowledge (e.g., orthographic, word discrimination, syntactic, emotional content, and general semantic domain knowledge) are being measured. The study's hypotheses are that children with LLD, like typically developing peers, will demonstrate partial word knowledge growth from exposure to unfamiliar words in text, but that they will show a different pattern of growth across the five forms of partial word knowledge being assessed.
