非利手动作电子游戏训练对发展性阅读障碍汉语儿
童影响的ERP研究
中文摘要
目的：探讨非利手动作电子游戏训练对视觉空间注意的影响机制、对阅读障碍的影响效果以及视觉空间注意与发展性阅读障碍的关系。方法：通过问卷在1225名儿童中筛选出发展性阅读障碍儿童8名为实验被试。被试进行9天共12小时的非利手动作电子游戏的干预，采用EGI-64导联脑电仪，分别记录干预前后完成有效提示、无效提示任务与汉字识别任务时的行为反应和EEG数据。结果：实验一结果，P1成分脑区主效应呈现显著差异，前、后测试与提示线索之间呈现显著差异；N1成分脑区主效应呈现显著差异，前、后测试与提示条件的交互效应在显著边缘；P2成分前、后测试、脑区、提示条件三者交互作用呈现显著差异；实验二结果，P1成分脑区主效应呈现显著差异，前、后测试与脑区的交互效应呈现不显著，N170成分脑区主效应呈现显著差异，前、后测试与脑区交互效应呈现不显著。实验一、二反应时均无差异，呈现不显著的结果的原因是由于被试过少以及干预训练时间相对较短造成，但数据结果均呈现良性趋势变化，反应时变短，被试的刺激位置的分析判断能力提高，文字识别能力有所呈现提升。结论：（1）非利手动作电子游戏训练对发展性阅读障碍儿童的视觉空间注意加工能力具有显著的改善作用。被试存在单侧视觉忽视问题，而大脑右侧顶叶损伤更容易造成单侧视觉忽视。通过训练后，单侧视
觉忽视问题有所改善。右脑区在处理相同任务时更具有优势，视觉注意范围以及注意集中度的调控能力有所提高，其调控着对非注意的抑制，支持右脑区顶叶控制着视觉空间注意。（2）非利手动作电子游戏训练对发展性阅读障碍具有改善趋势。发展性阅读障碍儿童前测试时左脑区激活程度小于右脑区，非利手动作电子游戏干预训练之后，在后测试时左脑区激活程度大于右脑区，文字加工存在左脑区优势。（3）与视觉空间注意和阅读障碍相关的“背侧通路”传导功能有所提高，右脑区顶叶和梭状回以及V1、MT区激活增强，随着视觉空间注意加工能力与发展性阅读障碍两者共同神经机制的激活增强，视觉空间注意加工能力提升与汉字识别能力提高呈现出正相关。

The Effect of Non-dominant Handedness Action Video Game Training on Chinese Children with Developmental Dyslexia:an ERP Study
Abstract
Objective:This study aims to explore the mechanism of non-dominant handedness action video game training on visual spatial attention,its effect on dyslexia and the relationship between visual spatial attention and developmental dyslexia.Methods:8children with developmental dyslexia were screened out from 1225children by questionnaire.The subjects were given12hours of non-dominant handedness
action video game intervention for9days.Before and after the intervention,the behavioral responses and EEG data of valid cue task,invalid cue task and Chinese character recognition task were recorded by using EGI-64lead Electroencephalogram Device.Results:in Experiment1,the main effect of P1in brain area showed significant difference and there was significant difference between the tests before and after the experiment and the cue;the main effect of N1in brain area showed significant difference and the interaction effect between the tests before and after the experiment and cue condition was on the significant edge; the interaction effect among the tests before and after the experiment,brain area and cue condition showed significant difference;in Experiment2,the main effect of P1in brain area showed significant difference and the interaction effect between the tests before and after the experiment and the brain area showed no significant difference,the main effect of N170in brain area showed significant difference,the interaction effect between the tests before and after the experiment and the brain area showed no significant difference.There was no difference in response time between Experiment1and Experiment2.The reason for the inconspicuous results was that there were too few subjects and the intervention training time was relatively short,but the data showed a positive trend.The response time was shorter,the ability of analysis and judgment of stimulus location was improved,and the ability of character recognition was improved.Conclusion:(1)Non-dominant handedness action video game training can significantly improve the visual spatial attention processin
g ability of children with developmental dyslexia.The subjects had unilateral visual neglect, and the right parietal lobe injury was more likely to cause unilateral visual neglect.
After training,unilateral visual neglect improved.The right brain area have more advantages in processing the same task,and the regulation ability of visual attention range and attention concentration has been improved.It regulates the inhibition of non-attention and supported the right parietal lobe to control visual spatial attention.
(2)Non-dominant handedness action video game training has a trend to improve developmental dyslexia.The activation degree of the left brain area was less than that of the right brain area in the pre-test of children with developmental dyslexia.After the intervention training of non-dominant handedness action video games,the activation degree of the left brain area was greater than that of the right brain area in the post-test.There is an advantage of the left brain area in word processing.(3)The conduction function of“dorsal stream”related to visual spatial attention and dyslexia is improved,and the activation of right parietal lobe and fusiform gyrus,V1and MT are enhanced.With the activation of the common neural mechanism of visual spatial attention processing ability and developmental dyslexia,the improvement of visual spatial attention processing ability is positively related to the improvement of Chinese character recognition ability.
