STUDY OF CENTRAL AUDITORY TEST BATTERY ON CHILDREN WITH LEARNING DISABILITY

学习障碍儿童在中枢神经系统有一定的问题症状，同时在言语行为上也有一定的问题，对其进行中枢性听力功能诊断是非常必要的。本研究旨在开发一些测试电池来诊断高级听觉处理系统对语音和语言的处理功能。在平成7年和8年进行的工作之后，在平成9年，研究人员对学习障碍儿童进行了“过滤语音测听”、“时间扭曲语音测听”、“双耳融合测试”、“二分听力测试”、“交替语音测试”、“二分竞争信息测试”，并对每个测试词进行了检查。“全竞争测试”和“部分竞争测试”是对以前的二分听力测试中的双音节单词和四音节单词进行一些修改而发展起来的（吉野，1981;1985）。这些测试单元分别应用于因中枢神经系统缺陷而怀疑有感觉神经和/或听力损失的小学生，他们去听障儿童资源室。从“婴儿三音节单词”中选取“交替言语测试”的20个句子，从“日常生活句”中选取3个或4个短语，包括3个练习任务的13个句子。“交替言语测试”分为两部分：(1)“右耳/左耳/右耳”如“Gakkowa（右耳）/Yasumini（左耳）/Shimasyo（右耳）”，(2)“左耳/右耳/左耳”如“Denwade（左耳）/Takushiwo（右耳）/Yobimasyo（左耳）”。选择10个4 ~ 5岁儿童容易理解的三或四短语句子进行二分竞争信息测试。这些测试项目分别应用于11名有学习障碍的儿童，然后进行分析。

It is essential for children with learning disorders, who have a certain problematic symptom with central nerve system and who also have some problems in their verbal behavior, to be diagnosed the central hearing function audiologically. The study aimed to develop some test batteries to diagnose the processing function to the speech and language in Higher Auditory Processing System. The work conducted in the year Heisei 7 and 8 were followed in the year, Heisei 9, in which the researchers conducted and examined each testing words by applying "Filtered Speech Audiometry", "Time Distorted Speech Audiometry", "Binaural Fusion Test", "Dichotic Listening Test", "Alternatlng Speech Test", "Dichotically-Competing Message Test" to children with learning disorders."All Competing Test" and "Part Competing Test" were developed by giving some modifications to the words with two syllables and words with four syllables of the previous Dichotic Listning Test (Yoshino, 1981 ; 1985). These test batteries were applied individually to the elementary school pupils having been suspicious of sensory-neural and/or hearing loss caused by some deficiencies in central nerve system, who go to the resource rooms for hearing impaired chidlren. Twenty sentences of "Alternating Speech Test" were selected from the "Words With Three Syllables For Infants" and 13 sentences with tree or four phrases including three tasks for practice were selected from "Daily Living Sentences". "Alternating Speech Test" was divided into two parts : (1) "Right Ear/Left Ear/Right Ear" such as "Gakkowa (Right Ear) /Yasumini (Left Ear) /Shimasyo (Right Ear)", (2) "Left Ear/Right Ear/Left Ear" such as "Denwade (Left Ear) /Takushiwo (Right Ear) /Yobimasyo (Left Ear). Ten three or four-phrase sentences, which were easily understood by 4 to 5 year children, were selected for Dichotically-Competing Messages Test. These test items were applied to eleven chidlren with learning disabilities individually and later analyzed.
