视觉、听觉注意力缺损与学习障碍关系探讨

Explore to the relationship between visual,auditory defects and learning disabilities.

【目的】探索儿童的视觉、听觉注意力缺损与学习障碍(learning disabilities,LD)的关系,为LD的诊治提供依据。【方法】对247例LD儿童和89名正常儿童进行持续视觉、听觉注意力测量。【结果】 LD儿童视觉、听觉注意力缺损百分率为48.51±25.13和56.48±22.04,而正常儿童组分别为:21.6±16.32和24.47±22.04,障碍组的视觉、听觉注意力缺损率显著高于正常儿童。研究还发现儿童随年龄每增加1岁,LD组和正常组的视觉注意力缺损率平均减少7.012%和3.964%,听觉注意力缺损率平均减少4.290%和3.046%。随着年龄的增长,儿童的视觉、听觉注意力缺损率均有所好转。【结论】视觉、听觉注意力缺损率增加导致儿童LD,应引起医务工作者的重视。

【Objective】 To explore the relationship between visualor auditory defects and learning disabilities of children. 【Methods】 Based on 247 cases of children with learning disabilities and 89 normal children sustained visual,auditory attention measure. 【Results】 In children with learning disabilities,percentage of visual,auditory attention defect were 48.51±25.13 and 56.48±22.04,whilein the normal children group were 21.6±16.32 and 24.47±22.04.The rate of visual,auditory attention defect in learning disabilities was significantly higher than normal children.it was also found that each additional one-year-old children＇s age,learning disability group and normal group of visual attention defects reduced averagely by 7.012 percent and 3.964 percent,auditory attention was reduced averagely by 4.290 percent and 3.046 percent.As the age increases,the defect rate of children＇s visual,auditory attention was greatly reduced. 【Conclusions】 The increasing of visual,auditory attention defect rate will lead to children＇s learning disabilities.
