Sensitivity to Subject-Verb Agreement in Children with Developmental Language Disorders: A comparison of developmental dyslexia with SLI

Abstract

"Developmental dyslexia refers to an impairment in reading and writing, despite average intellectual ability and normal educational opportunity. The average population risk of developmental dyslexia is around 3-10%. However, the risk of first-degree relatives of dyslexics is estimated to be 40% (Gilger et al., 1991), suggesting a genetic component to the disorder. Converging evidence suggests that the source of the reading and writing problems is in the phonological domain, even though visual deficits are also observed in developmental dyslexia (Lovegrove, 1994)"
