BACKGROUND
In this paper the dichotic tests and the CERA (Cortical Evoked Response Audiometry) of children with dyslexia had been examined, in order to find out if there are auditory processing and perception disorders.
PATIENTS AND METHODS
33 children with dyslexia had been compared with 28 children without problems of writing and reading. The mean age of the children was 9 years. All of the children had been examined by the following audiometric measurements: tympanometry, pure-tone-audiometry, speech-audiometry, dichotic Tests by Uttenweiler and Feldmann and the Cortical Evoked Response Audiometry (CERA) rated according to Esser.
RESULTS
The intelligence quotients were in the group of dyslexic children significantly lower. The Uttenweiler and Feldmann tests were in dyslexic children significantly lower in the control group as well. The late cortical responses ware normal or near normal in both groups.
CONCLUSION
Dichotic speech tests indicate central auditory processing and perception deficits in dyslexia. These tests are confounded, however, by attention and memory deficits. The CERA rated according to Esser does not point out to these auditory disorders in dyslexia.
背景
本文对诵读困难儿童进行了双耳分听测试和皮层诱发电位测听（CERA），以确定是否存在听觉加工和感知障碍。
患者与方法
将33名诵读困难儿童与28名无读写问题的儿童进行比较。儿童的平均年龄为9岁。所有儿童均接受了以下听力测量：鼓室图、纯音听力测定、言语听力测定、由乌滕魏勒和费尔德曼进行的双耳分听测试以及根据埃塞尔标准评定的皮层诱发电位测听（CERA）。
结果
诵读困难儿童组的智商显著较低。在对照组中，诵读困难儿童的乌滕魏勒和费尔德曼测试结果也显著较低。两组的晚期皮层反应均正常或接近正常。
结论
双耳分听言语测试表明诵读困难存在中枢听觉加工和感知缺陷。然而，这些测试受到注意力和记忆缺陷的干扰。根据埃塞尔标准评定的CERA并未指出诵读困难中的这些听觉障碍。
