Theoretical and methodological pitfalls in making comparisons between developmental and acquired dyslexia: Some comments on A. Castles & M. Coltheart (1993)
Snowling MJ., Bryant PE., Hulme C.
On the basis of a study of the reading skills of 56 developmental dyslexies, Castles & Coltheart (1993) have proposed that there are at least two varieties of dyslexia in children. In the first, there is an impairment of lexical reading and in the second, the operation of the sublexical procedure is impaired. We take issue with their, proposal on theoretical grounds and argue that methodological weaknesses in their study seriously weaken their claims. © 1996 Kluwer Academic Publishers.
