Sequential or simultaneous visual processing deficit in developmental dyslexia?
The ability of dyslexic children with or without phonological problems to process simultaneous and sequential visual information was assessed using two tasks requiring the oral report of simultaneously or sequentially displayed letter-strings. The two groups were found to exhibit a simultaneous visual processing deficit but preserved serial processing skills. However, the impairment in simultan...
متن کاملAttenuated hemispheric lateralization in dyslexia: evidence of a visual processing deficit.
There is controversial evidence that deficits in the processing of low contrast and low spatial frequency stimuli are of importance in the pathogenesis of dyslexia. Fifteen adult dyslexics and 19 controls were examined using visual evoked potentials (VEP) at varying spatial frequencies (2 and 11.33 cpd) and contrasts (0.2, 0.4, 0.6, 0.8). Our results show that the amplitude of VEPs following di...
متن کاملDeficit of visual contour integration in dyslexia.
PURPOSE The visual processing of text occurs spontaneously in most readers. Dyslexic persons, however, often report both somatic symptoms and perceptual distortions when trying to read. It is possible that the perceptual distortions experienced by those with dyslexia reflect a disturbance in the basic mechanisms supporting perceptual organization at the early stages of visual processing. Integr...
متن کاملVisual processing and dyslexia.
Magnocellular-pathway deficits have been hypothesized to be responsible for the problems experienced by dyslexic individuals in reading. However, research has yet to provide a detailed account of the consequences of these deficits or to identify the behavioural link between them and reading disabilities. The aim of the present study was to determine the potential consequences of the magnocellul...
متن کاملIs dyslexia caused by a visual deficit?
A number of studies have found that dyslexic readers suffer from visual deficits A causal relationship has yet to be established. One step toward establishing such a relationship would be to demonstrate that the degree of dyslexia can be altered by manipulating a purely visual variable. One such variable would be the size of the printed text. In a recent study (O'Brien, Mansfield, & Legge, 2000...
