ADHD儿童听觉注意能力及音素感知能力研究

Auditory attention and pure tone perception in ADHD children

目的了解ADHD儿童及正常对照儿童在音素感知能力上的差别,以及音素感知能力与儿童注意力和冲动性之间的关系。方法所有研究对象均接受:听觉持续性操作测试和纯音辨识测试。所有数据进行t检验,相关性分析和线性回归分析。结果(1)听觉CPT:ADHD组的错误数、漏报数和β值均高于对照组;ADHD组的反应时间较对照组延长;ADHD组的d’值低于对照组。差异具有显著性意义。(2)纯音辨识测试:ADHD组儿童完成情况较正常对照儿童差,差异不具有显著性意义。结论(1)ADHD儿童的听觉警觉性和听觉注意能力低于正常儿童。(2)控制注意力因素和冲动性行为后,ADHD儿童对纯音的辨识能力与正常儿童没有显著差异。

Objective To investigate the characteristics of Pure Tone Discriminating function in ADHD children and it＇s relationship with their attention and impulsion. Methods The Auditory Continuous Performance Test （CPT） and the Pure Tone Discriminating Test were administered to all the children. All the dates were statisticed with SPSSll. 5 in the computer. Results （1）The Auditory CPT： The commission errors, omission errors and the scores of β in ADHD children were higher than in control children （P 〈 0.05, P 〈 0. 001 and P 〈 0. 001 , respectively）. The mean hit reach time in ADHD children was longer than in control children （P〈0. 001）. The scores of d＇ in ADHD children were lower than in control children （P 〈 0. 001）. （2）Pure Tone Discriminating Test： The scores of pure tone detection and discrimination in ADHD children were lower than in the control children （P 〈 0.05）. Conclusions （1）The ability of alert and perception of ADHD children are weak than those of normal children. （2）There is no difference in the auditory perception of pure tone between ADHD children and normal children.
