The Competing Words Subtest is a commonly used dichotic listening test for assessing binaural integration in children suspected of having an auditory processing disorder. In 124 children, standard scores from the subtest suggested a binaural integration deficit in 23% of the children tested. Because standard scores are derived from the combined scores of both ears during the test, children with normal performance in one ear and weak performance in the other ear may be overlooked. For these children, a measure of interaural asymmetry may be a more sensitive indicator of a binaural integration deficit. When an age-appropriate criterion for interaural asymmetry from the Competing Words Subtest was used, the incidence of a binaural integration deficit increased to 51% of the children tested. Four typical patterns of dichotic listening performance were identified based on results from the two scoring techniques.
竞争词汇子测试是一种常用的双耳分听测试，用于评估疑似有听觉处理障碍儿童的双耳整合能力。在124名儿童中，该子测试的标准分数显示，接受测试的儿童中有23%存在双耳整合缺陷。由于标准分数是根据测试期间双耳的综合分数得出的，一只耳朵表现正常而另一只耳朵表现较弱的儿童可能会被忽视。对于这些儿童，耳间不对称测量可能是双耳整合缺陷更敏感的指标。当使用竞争词汇子测试中适合年龄的耳间不对称标准时，双耳整合缺陷的发生率增加到接受测试儿童的51%。根据两种评分技术的结果，确定了四种典型的双耳分听表现模式。
