英语学习困难在我国存在普遍性和严重性,对英语学困生的干预和矫治已成为研究者亟待研究的课题。本研究使用国家专利产品“易学灵”(Enjoy Learning)人机对话系统对英语学困生进行为期三个月的干预。这一人机对话系统是国内第一个将计算机游戏与行为认知能力提升结合人机对话系统,获得我国技术专利,专利号:ZL2012 2 0181187.4。本研究采用实验组对照组前测后测设计,将32名初一英语学困生分为同质的两组,训练组接受历时一个学期的每天30分钟的“易学灵”人机对话系统训练,对照组则只进行常规学习生活,不接受训练。训练前后,两组被试均接受视觉oddball任务的注意力集中的脑电测试。在行为测验进步显著基础上,进一步以事件相关电位P300成分为脑电指标评估脑机制干预效果。结果发现,训练组的后测P300潜伏期比前测显著缩短,而对照组前后测P300潜伏期则无显著差异,表明“易学灵”人机对话系统能够提高英语学困生的信息加工效率。本研究利用P300来衡量认知水平经过干预研究之后是如何提升的。这是脑神经认知科学与人机交互课程培训的最新结合创新型的研究。
English learning difficulties exist in our country universality and seriousness, intervention and correction of English learning difficulties students have become the subject of urgent research. This research uses a national patent product “Enjoy Learning” man-machine dialogue system to intervene in English for three months. This man-machine dialogue system is the first in China that combines computer games and behavioral cognitive abilities with man-machine dialogue systems and has won our patent for technology. Patent No .: ZL2012 2 0181187.4. In this study, the experimental group control group before and after the test design, the 32 first-year English students with learning disabilities were divided into two groups, the training group to accept one semester for a period of 30 minutes a day “easy to learn spirit” man-machine dialogue System training, the control group only routine learning, do not receive training. Before and after training, both groups received attention-intensive EEG tests of the visual oddball task. Based on the significant progress of behavioral tests, the effect of brain mechanism intervention was further evaluated using the P300 component of event-related potentials as the EEG index. The results showed that the P300 latency of the training group was significantly shorter than that of the pretest and that of the control group before and after P300 latency was no significant difference, indicating that “Yi Xue Ling ” man-machine dialogue system can improve the information processing efficiency of English learning difficulties. The present study uses P300 to measure how cognitive levels improve following intervention studies. This is the latest combination of innovative research in the training of brain-based cognitive science and human-computer interaction courses.
