聋哑儿童视觉反应时对比研究

Comparative investigation on deaf-mute children's optical reaction time

目的 探讨聋哑儿童与正常儿童视觉反应时的差别及影响因素。方法 采用计算机反应时测试软件系统 ,对 93名 7～ 13岁聋哑学生进行了视觉反应时的测定及分析。结果 聋哑儿童视觉简单和视觉复杂反应时的各项测试指标均慢于正常儿童 ,2组间有非常显著差异 (P <0 0 1) ;视觉对比反应时的最快反应时、反应错漏率 ,2组间有显著性差异 (P <0 0 5或P <0 0 1)。结论 聋哑儿童视觉反应时慢于正常儿童。提高聋哑儿童视觉信息处理能力对其智力开发具有重要意义。

Objective To explore the difference of optical reaction t ime between deaf-mute children and normal ones,and the affecting facotrs.Methods 93 deaf-mute children who came from Shenyang ward deaf-mute school were selected to assess the comparative analysis in optical re action time by using the computer reaction time test system.Results there was marked difference in those test results determined by menstruating simple optical reaction time and complex optical reac tion time between two groups (P<0.01).Conclusion The optical reaction time of deaf-mute childre n was slower than that of normal ones.It was significant to measure reactio n time for directing the education to deaf-mute children and developing the functi on of brain.
