The role of attention in the differentiation of auditory processing disorders from attention deficit disorders is gaining considerable interest in both the clinical and research arenas. It has been well established that when attention is directed to one ear or the other on traditional dichotic tests, performance can be altered. However, preliminary studies in our laboratory have shown that dichotic fusion paradigms are resistant to shifts in ear performance associated with changes in attention. The purpose of this study was to assess the performance of normal listeners on a dichotic consonant-vowel and a dichotic rhyme (fusion) test. Both test procedures were administered to 20 young adults in three different listening conditions (free recall, attention directed to the left ear, and attention directed to the right ear). Results from this study supported the hypothesis that dichotic rhyme tests are resistant to alterations in the laterality of attention and have implications for the development of test paradigms that can be used to segregate attention from pure auditory deficits in the clinical domain.
在临床和研究领域，注意力在区分听觉处理障碍与注意力缺陷障碍方面所起的作用正引起人们极大的兴趣。众所周知，在传统的双耳分听测试中，当注意力集中于一只耳朵时，测试表现会发生改变。然而，我们实验室的初步研究表明，双耳融合范式对与注意力变化相关的耳朵表现变化具有抗性。本研究的目的是评估正常听力者在双耳辅音 - 元音和双耳押韵（融合）测试中的表现。两种测试程序在三种不同的听力条件下（自由回忆、注意力集中于左耳、注意力集中于右耳）对20名年轻成年人进行了测试。本研究结果支持了以下假设：双耳押韵测试对注意力偏向的改变具有抗性，并且对开发可用于在临床领域将注意力与单纯听觉缺陷区分开来的测试范式具有启示意义。
