Cross-cultural studies have suggested that reading deficits in developmental dyslexia (DD) can be moderated by orthographic depth. To further explore this issue and assess the moderating role of orthographic depth in the developmental cognitive trajectories of dyslexic and typical readers, we systematically reviewed 113 studies on DD that were…

This article presents a theoretical overview at the cognitive level of the role of phonological awareness in reading development and developmental dyslexia across languages. It is argued that the primary deficit in developmental dyslexia in all languages lies in representing speech sounds: a deficit in phonological representation. (Contains…

Discussion of the teaching of writing, spelling, and reading using code-based literacy methods, such as Orton-Gillingham examines the cognitive challenge of the transition from spoken to graphic word and then reviews new research findings, such as the letter as model for sound variation, ease of spelling the low vowel, and the creation of word…

This literature-based review examines the relationship between the acquisition of segmental awareness and the acquisition of alphabetic literacy. Cited studies show that the segmental analysis ability of most dyslexics is very poor and suggest one factor may be related to the conscious representation of speech on which the analytic capacity…
