Causal explanations of dyslexia

The relationship between motor control and phonology in dyslexic children. Evidence from dyslexia and poor reading comprehension. Sixteen dyslexic and 16 control university students were administered a full battery of psychometric, phonological, auditory, visual and cerebellar tests.

Short- and long-term effects of training phonological awareness in kindergarten: Annals of Dyslexia,53, It is postulated that retarded or dysfunctional articulation would lead to deficient phonological representations. Training phonological awareness with and without explicit attention to articulation.

The reading speed of patients was measured before and after positional treatments in some cases to obtain information on the effect. Neuroimaging methods including functional magnetic resonance imaging fMRIelectroencephalography EEG, and event-related potentials or ERPsand magnetoencephalography MEGhave revealed the brain regions most consistently involved in single word reading.

Biological theories of dyslexia

The disorder has lifelong persistence, reading retardation being merely one of its manifestations. Journal of Research in Special Educational Needs, 6, We will therefore not discuss the visual and auditory theories independently. Stein argues that the visual system provides the main input to both the lexical and the sublexical routes for reading and therefore this should be seen as the most important sense for reading is vision.

Implications for early intervention. An introduction to the special issue on the double-deficit hypothesis. Wolf, M and Bowers, PG Response to intervention as a vehicle for distinguishing between children with and without reading disabilities: Wiring of the Brain In connection with the cell misplacement in the first theory, another theory is that dyslexia is caused by a unique wiring in the brain.

Originator of the term dyslexia". All poor readers are not dyslexic. In Schools in G.Finally, our data raise the question whether motor problems play any causal role in dyslexia. Contrary to the predictions of the cerebellar theory, we found no influence of motor/cerebellar performance either on phonology or on literacy.

This model is influential because it explains both dyslexia and literacy from causal and behavioural perspectives.

The low-level impairments proposed by the magnocellular and cerebellar explanations of dyslexia are present in many developmental disorders, and cannot be accepted as causal explanations of developmental dyslexia.
