Abstract
Chinese children with developmental dyslexia (DD) have been found to show a deficit in processing multi-elements in a variety of visual tasks parallelly. Nevertheless, the potential mechanisms of this visual simultaneous processing deficit and its relation to the reading ability still remain unclear. The ability of simultaneously processes multi-character strings is restricted by different cognitive components, including perceptual processing speed, visual short-term memory capacity, selective spatial attention distribution pattern, and the ability to inhibit distractors. Therefore, this article attempted to explore the potential mechanisms underlying the visual simultaneous processing in Chinese children with DD in the framework of the theory of visual attention (TVA). Two experiments are conducted to investigate the fundamental cognitive components regarding the visual simultaneous processing skill, with further examining the relationship between these as A modified combined theory of visual attention (CombiTVA) to collect participants’ during the multi-element processing. Based on the response accuracy in each level of CombiTVA the four including processing speed (C), visual short-term storage (K), attentional ( ), and ( We four between hierarchical regression TVA two the from high and low grades reduced perceptual multiple parallel, significant differences in the selective spatial attention distribution between dyslexic and normal are only in Experiment 1 with Chinese characters as Experiment 2 with nonverbal symbols as multi-processing balanced in attentional distribution observed in DDs from both two grade groups; attentional weight of normal readers from right-lateralized Further hierarchical regression analyses reveals that the impaired components of visual simultaneous with different levels of the component of perceptual processing speed independently effectively accounts for the variance of the sentence reading while the of selective spatial attention distribution to the single-character reading speed. the modulation of specificity visual simultaneous processing skills to improve reading efficiency in the dyslexics.
