学习困难儿童视觉搜索的眼动研究

本研究利用眼动记录技术,探讨学习困难儿童(学困儿童)视觉搜索过程的眼动特性。要求被试搜索结束后报告搜索结果。结果发现,与学习优秀儿童、学习一般儿童相比,学困儿童视觉搜索的效率低。在视觉搜索的眼动模式上,学困儿童注视次数多,与其他两组儿童差异显著。结果提示我们,学困儿童的眼动效率低与视觉搜索效率低关系密切。

A Research on Eye Movement of Children with Learning Difficulities in Visual Search

The method of recording eye movement is used to investigate the characteristics of cognitive processing and eye movement of children with learning difficulties(LD) in the process of visual search.The subjects are required to report the results of visual search.The results indicate that:(1) Compared with excellent children and average children,children with LD have poorer ability of visual search and lower efficiency in picking up useful information.(2) About the model of eye movement,children with LD have more fixation and less saccadic distance,which shows significant difference compared with excellent children and average children.These results suggest that the poor efficiency of eye movement of children with LD is closely related with the low efficiency of visual search.
