dcterms.abstract | Aims: This pilot study investigated perceptual and electrophysiological characteristics of dyslexic children, and evaluated the immediate and prolonged effect of visual perceptual training on these characteristics in these children. | - |
dcterms.abstract | Methods and procedures: Seven dyslexic children and seven controls aged 7-8 years were recruited and completed this study. All dyslexic children completed 10-weeks of visual perceptual training. The visual perceptual skills were assessed and binocular visual evoked potentials (VEP) were recorded with two different pattern stimulations initially (Baseline), 3 months after the first assessment (Evaluation I) and 6 months after first assessment (Evaluation II). | - |
dcterms.abstract | Outcomes and results: A significant reduction (p = 0.021) in VEP amplitudes in the dyslexic subjects in response to 15 Hz reversal frequency at 15% contrast stimulation was found, compared with controls, prior to perceptual training. A significant correlation (p = 0.005) was found between the VEP amplitude with 15 Hz reversal frequency and the total score of Test of Visual Perceptual Skills (non-motor) revised (TVPS-R). After training, dyslexic subjects scored higher in some of the visual perceptual tasks and these improvements persisted for 3 months. However, the VEP amplitude in the dyslexics showed no significant change after perceptual training. | - |
