视障人群与正常人群听觉注意力稳定性比较

The Comparison of Attention Stability of Auditory between the Blind and the Normal Individuals

为了探究视障人群与正常人群在执行听觉任务时的听觉注意力稳定性的差别,设计了一个从临界带宽噪音中检测纯音的实验,分别由视力正常的大学生和视障大学生完成。从两组人群纯音检出率和反应时间的随实验时间变化这两个方面进行了分析,发现视障大学生检出率变化的稳定性优于正常学生,而反应时间的变化趋势也没有出现正常学生下降的情况,证明视障大学生的听觉注意力稳定性优于视力正常大学生。

A psychoacoustic experiment to detect tones masked by critical - band noise is carried out to study the stability of auditory attention between the visually impaired and the normal. The experiment is done by blind and normal university students. Analysis is made from the change of detection rate of tones and response latency. The result shows that the blind in- dividuals have advantages than the normal in the aspect of auditory attention.
