conclusions kannada children with rd were particularly poor on simultaneous and successive processing. our results support the heterogeneity view of rd. results independent-samples t tests (two-tailed) showed significant difference between the groups on all the pass component subtests. the pass scores of children with rd were scattered unevenly around the average to well below the average range...

The emerging etiological model for developmental disorders, like dyslexia, is probabilistic and multifactorial while the prevailing cognitive model has been deterministic and often focused on a single cognitive cause, such as a phonological deficit as the cause of dyslexia. So there is a potential contradiction in our explanatory frameworks for understanding developmental disorders. This paper ...

Three groups of children with dyslexia, mean age 8, 13 and 17 years, and three groups of normally achieving children matched for age and IQ with the dyslexic groups undertook three tests of motor skill. For peg placing and articulation rate, the children with dyslexia were significantly slower than their chronological age controls, and equivalent to their reading age controls. For bead threadin...

It has been commonly agreed that developmental dyslexia in different languages has a common biological origin: a dysfunction of left posterior temporal brain regions dealing with phonological processes. Siok, Perfetti, Jin, and Tan (2004, Nature, 431, 71-76) challenge this biological unity theory of dyslexia: Chinese dyslexics show no deficits in posterior temporal brain regions but a functiona...

Theories of developmental dyslexia differ on how to best interpret the great variety of symptoms (linguistic, sensory and motor) observed in dyslexic individuals. One approach views dyslexia as a specific phonological deficit, which sometimes co-occurs with a more general sensorimotor syndrome. This article on the neurobiology of dyslexia shows that neurobiological data are indeed consistent wi...

Dyslexia is a specific impairment in reading that affects 1 in 10 people. Previous studies have failed to isolate a single cause of the disorder, but several candidate genes have been reported. We measured motion perception in two groups of dyslexics, with and without a deletion within the DCDC2 gene, a risk gene for dyslexia. We found impairment for motion particularly strong at high spatial f...

Dyslexia is one of the most common learning disabilities, yet its brain basis and core causes are not yet fully understood. Neuroimaging methods, including structural and functional magnetic resonance imaging, diffusion tensor imaging, and electrophysiology, have significantly contributed to knowledge about the neurobiology of dyslexia. Recent studies have discovered brain differences before fo...

The emerging etiological model for developmental disorders, like dyslexia, is probabilistic and multifactorial while the prevailing cognitive model has been deterministic and often focused on a single cognitive cause, such as a phonological deWcit as the cause of dyslexia. So there is a potential contradiction in our explanatory frameworks for understanding developmental disorders. This paper a...

Dyslexia is a cognitive disorder that affects the evolutionary ability to read, write, and speak in people, affecting correct learning of large percentage population worldwide. In fact, incorrect caused because educational system does not take into consideration accessibility parameters people with dyslexia need maintain sustainable level equal others. Moreover, use mobile devices, such as smar...
