In this study, we concurrently investigated 3 possible causes of dyslexia-a phonological deficit, visual stress, and a reduced visual attention span-in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of response accuracy (92.1% of the sample), speed (84.8%), or both (79.3%). Deficits in visual attention span, as measured by partial report ability, affected 28…

The results challenge the notion that a unifying deficit characterizes dyslexia and indicate a model where reading skill is explained by several distinct, additive predictors, or risk factors, of reading (disability).

What is Developmental Dyslexia?

It is argued that this theory is set at too high a cognitive level to be explanatory; it is discussed how the ‘magnocellular theory’ attempts to do this in terms of slowed and error prone temporal processing which leads to dyslexics’ defective visual and auditory sequencing when attempting to read.
