Dyslexia is characterized by difficulties in learning to read and there is some evidence that action video games (AVG), without any direct phonological or orthographic stimulation, improve reading efficiency in Italian children with dyslexia. However, the cognitive mechanism underlying this improvement and the extent to which the benefits of AVG training would generalize to deep English orthography, remain two critical questions. During reading acquisition, children have to integrate written letters with speech sounds, rapidly shifting their attention from visual to auditory modality. In our study, we tested reading skills and phonological working memory, visuo-spatial attention, auditory, visual and audio-visual stimuli localization, and cross-sensory attentional shifting in two matched groups of English-speaking children with dyslexia before and after they played AVG or non-action video games. The speed of words recognition and phonological decoding increased after playing AVG, but not non-action video games. Furthermore, focused visuo-spatial attention and visual-to-auditory attentional shifting also improved only after AVG training. This unconventional reading remediation program also increased phonological short-term memory and phoneme blending skills. Our report shows that an enhancement of visuo-spatial attention and phonological working memory, and an acceleration of visual-to-auditory attentional shifting can directly translate into better reading in English-speaking children with dyslexia.
阅读障碍的特征是学习阅读困难,有证据表明,动作视频游戏(AVG)在没有任何直接语音或正字法刺激的情况下,可以提高意大利阅读障碍儿童的阅读效率。然而,这种改善的认知机制,以及 AVG 训练的益处是否会推广到英语深正字法,仍然是两个关键问题。在阅读习得过程中,儿童必须将书面字母与语音结合起来,迅速将注意力从视觉模式转移到听觉模式。在我们的研究中,我们在玩 AVG 或非动作视频游戏前后,测试了两组匹配的英语阅读障碍儿童的阅读技能和语音工作记忆、视空间注意力、听觉、视觉和视听刺激定位以及跨感觉注意力转移。玩 AVG 后,单词识别和语音解码的速度提高了,但非动作视频游戏没有。此外,只有在接受 AVG 训练后,集中的视空间注意力和视觉到听觉注意力转移才会改善。这种非传统的阅读矫正方案还提高了语音短期记忆和音素混合技能。我们的报告表明,视空间注意力和语音工作记忆的增强,以及视觉到听觉注意力转移的加速,可以直接转化为英语阅读障碍儿童更好的阅读能力。
