Auditory processing disorder is a clinical entity that may be associated with several neuropathological disorders - learning disabilities among them.
To characterize and compare the performance of students with and without learning disabilities in speech tests with and without background noise, dichotic listening tests, alternating dissyllable test.
40 students of both genders, ranging from 8 to 12 years of age participated in this study. They were divided in two groups: GI - 20 students with learning disabilities and GII - 20 students with good academic performance matched according to gender, age and education with GI. The evaluation consisted of basic audiological evaluation and applying dichotic listening tests, alternating disyllable test and speech test in noise.
This is a cross-sectional study with a historical cohort.
The students of GI presented inferior performance compared to Group II (GII), both on dichotic listening tests and on alternating disyllable tests, and performance with no statistically significant difference on the speech in noise test.
The evidence found suggests that the group of children with learning disabilities shows inferior performance compared to the group without problems, reflecting difficulties on the processing of auditory information.
听觉处理障碍是一种临床病症,可能与多种神经病理学障碍相关,其中包括学习障碍。
对有学习障碍和无学习障碍的学生进行言语测试(包括有背景噪声和无背景噪声的测试)、双听测试、交替双音节测试,并对其表现进行描述和比较。
共有 40 名年龄在 8 至 12 岁之间的男女学生参与了本研究。他们被分为两组:GI-有学习障碍的 20 名学生和 GII-成绩良好的 20 名学生,根据性别、年龄和教育程度与 GI 相匹配。评估包括基本听力评估和应用双听测试、交替双音节测试和噪声中的言语测试。
这是一项具有历史队列的横断面研究。
GI 组的学生在双听测试和交替双音节测试中的表现均劣于 GII 组,而在噪声中的言语测试中表现无统计学差异。
研究结果表明,有学习障碍的儿童组的表现明显劣于无问题的儿童组,这反映了他们在听觉信息处理方面存在困难。
