摘要
采用因素实验设计,通过与正常学生与听力损伤学生对比实验研究,探讨汉语学习困难学生视觉加工速度和视觉瞬间信息整合的特征。结果表明:(1)汉语学习困难学生存在基本视觉加工速度不足以及汉语语言文字视觉加工的特异性困难;(2)汉语学习困难学生需要更长时间整合瞬间视觉信息,从而影响了其加工的速度;(3)适当延长视觉刺激整合的时间,可以有效提高其视觉加工的效率。这些结果对改善学生的汉语学习困难具有一定的指导意义。
Two experiments were conducted to explore the features of visual processing speed and temporal visual information processing in children aged 10-13 with Chinese learning difficuhies. In Experiment 1, the subjects were tested with pair-pictures cancellation, pair-phrasal cancellation and pair-similar-shape Chinese eharacted, cancellation, to compare the visual processing speed of poor readers, normal readers and hearing-deficit readers. The results indicated that the poor readers were much slower than the normal readers in processing the visual information, and even had more difficulty in reading with visual information of Chinese characters. In Experiment 2, the processing temporal visual information was tested by means of temporal integration tasks among three groups. The results showed that the deficit in temporal processing was characteristic of Chinese reading disabilities. It could also be the factor that affects the poor Chinese readers＇ visual information processing speed. The results also showed the poor Chinese readers＇ potential in Chinese learning if they had enough time to process the visual information.
