3～4岁听障儿童与健听儿童句子记忆测试结果比较

目的：探讨3～4岁经康复训练的听障儿童与健听儿童通过听觉记忆句子能力的差异。方法选取24例3～4岁经康复训练的听障儿童及14例同龄健听儿童，听障儿童再按助听时间1～2年（10例）和2～3年（14例）分为两组，以言语听觉反应评估（evaluation of auditory response to speech，EARS）中封闭式句子测试的两组图片分别对各组儿童进行测试，比较听障及健听儿童通过听觉完整记忆句子的正确率及平均次数。结果在记忆两组测试句的正确率方面，助听时间2～3年听障儿童第一组测试句的正确率是57．14％，与健听儿童的正确率（58．93％）接近，助听时间1～2年听障儿童的语句的正确率仅为32．5％，低于其他两组儿童；助听时间2～3年听障儿童第二组测试句的正确率是44．64％，高于助听时间1～2年听障儿童的正确率（22．5％），健听儿童的语句的正确率为55．36％，高于听障儿童组。健听、助听2～3年和助听1～2年听障儿童正确记忆第一组测试句的平均次数分别为2．36±1．08、2．29±1．68、1．30±1．25次，三组间差异无统计学意义（P＞0．05），但是在第二组测试句测试中，助听1～2年的听障儿童正确记忆句子的次数（0．90±0．57次）明显低于健听儿童（2．21±0．89次）（P＜0．01）和助听2～3年听障儿童组（1．79±1．89次）（P＜0．05），而助听2～3年的听障儿童组与健听儿童组之间差异无统计学意义（P＞0．05）。结论本组3～4岁听障儿童通过听觉正确记忆句子的能力随着助听时间的延长而提高，并逐渐接近同龄健听儿童，这一能力也受到测试内容的影响。

A Comparative Study of Auditory Memory in sentences between the Hearing-Impaired Children and Normal Children of 3~4 Years

Objective To investigate the differences of the correct memorization of a sentence with auditory between the hearing-impaired children after rehabilitation training and normal children.Methods Twenty-four hearing-impaired children and 14 normal hearing children at age 3~4 were selected.The hearing-impaired chil-dren were divided into two groups according to the length of the hearing device.The closed-set sentence test of e-valuation of auditory response to speech (EARS)was used.Results 1 .In the first test,the hearing-impaired chil-dren with hearing device 2 to 3 years whose correct rate was 57.14%were close to the normal children whose correct rate was 58.93%.The hearing-impaired children with hearing devices 1 to 2 years whose correct rate was 32.5%were worse than the children of other two groups 2 .In the second test,the hearing-impaired children with hearing devices 2 to 3 years whose correct rate was 44.64% were better than the hearing-impaired children with hearing devices 1 to 2 years whose the correct rate was 22.5%.The normal children whose the correct rate was 55.36%were better than the children of other two groups.3.There was no significant difference to correctly memorize a sen-tence between three groups in the first test,but there was significant difference to correctly memorize a sentence between the hearing-impaired with hearing device 1 to 2 years and the hearing-impaired children with hearing de-vice 2 to 3 years (P<0.05),and significant differences also existed between the hearing-impaired with hearing de-vice 1 to 2 years and normal children (P<0.05),but there was no significant difference between the hearing-im-paired children with hearing device 2 to 3 years and normal children (P>0.05).Conclusion The length with hear-ing device strengthens the ability of hearing-impaired children in correctly memorizing a sentence after rehabilitation training.And the content of test affects the result ,it provides reference to the hearing-impaired children's auditory training .
