Abstract: Developmental dyslexia is a specific disorder in reading acquisition, which will hinder the development of individuals. Many researchers focused on how to help the dyslexics to improve their reading skills. Traditional intervention methods are mainly based on phonological deficit of dyslexia, in which there are still some problems required to be solved such as consuming considerable time and labors in intervention implementation, and reading materials putting pressures on the dyslexic readers. In recent years, most of the relevant studies have indicated that an intriguing way of action video game intervention can significantly improve the dyslexics’ reading abilities, but its underlying mechanism remains unclear. Previous studies have explained these internal mechanisms from the aspects of visual spatial attention, cross-sensory attention shifting and visual motor processing. This article intends to integrate these explanations into the framework of the visual magnocellular deficit theory. Based on this theory framework, future research can further examine the internal mechanisms regarding the positive influence of playing action video games on reading skills, and can develop relevant intervention programs which are more suitable for the dyslexic readers.
