发展性阅读障碍学生的视觉认知能力研究

对发展性阅读障碍者在视觉认知中异常表现的研究属于该领域中的传统研究.国内对阅读障碍人群的视觉认知能力的研究较少,实验材料仅限于普通平面材料而未涉及立体线索.基于此,研究采用三维--不可能图形材料对发展性阅读障碍者视觉认知能力进行研究,研究发现:①在平面不可能图形材料辨识任务中,发展性阅读障碍学生判断正确性得分与对照组无显著差异.②在以彭罗斯三角原理构成的不可能图形材料辨识任务中,汉语环境下的发展性阅读障碍患者判断正确性得分优于对照组.

Abstract：

Traditional researches often focus on the abnormal visual cognitive ability of people with developmental dyslexia. In the past, there were few researches on dyslexia people's visual cognitive ability in China; moreover, they all used plane materials, not stereograms. In the present research, we conducted an experiment with stereograms which included impossible figures and tested the ability of subjects with developmental dyslexia. The results showed that when plane materials which included impossible figures were employed in the testing task, subjects with developmental dyslexia had similar scores to those of the control group, and that when we used impossible figures on the basis of Penrose Triangle Principia, subjects with developmental dyslexia in Chinese context had significantly greater correctness than the control group.
