Windsor, Jennifer; Hwang, Mina – Annals of Dyslexia, 1997
Knowledge of derivational suffix meanings was investigated in 10 subjects (ages 10-12) with language learning disabilities and typical peers. Students produced derived forms from nonce bases in an elicitation task and selected derived forms in a forced choice task. Elicitation task accuracy of subjects fell substantially below that of peers.…

Carlisle, Joanne F.; Stone, C. Addison; Katz, Lauren A. – Annals of Dyslexia, 2001
A study involving 18 children with reading difficulties (grades 4- 9), 33 children controls, and 19 adult controls found that poor readers have less difficulty reading words whose forms are phonologically and orthographically transparent than reading words the base forms of which undergo a phonological shift when a suffix is added.

Carlisle, Joanne F. – Annals of Dyslexia, 1987
Normal students (N=65) in fourth, sixth, and eighth grades were compared to 17 learning-disabled ninth graders on learning derivational morphology and spelling derived forms. Disabled students' knowledge of derivational morphology was equivalent to that of normal sixth graders, but spelling of derived forms was equivalent to that of fourth…

Champion, Ann – Annals of Dyslexia, 1997
A study measured and compared the semantic and syntactic knowledge of 20 sixth-grade students with reading disabilities, 20 fourth-grade typical readers, and 20 sixth-grade typical readers. Results indicate that students with reading disabilities were better able to demonstrate knowledge of suffixed words in oral language measures than in reading…
