Background: There is emerging evidence that individuals with developmental dyslexia show deficits in visual-spatial attention. This study focused on visual searches and examined whether visual search deficits would be found in Chinese children with dyslexia. More importantly, we examined the associations between dyslexia and distinct types of…

Previous studies of visually symptomatic dyslexics have found that their contrast thresholds for pattern discrimination are the same as non-dyslexics. However, when noise is added to the stimuli, contrast thresholds rise markedly in dyslexics compared with non-dyslexics. This result could be due to impaired noise exclusion in dyslexics. Some…
