本研究旨在确定两耳分听的性能和两个特定的语言功能和CT扫描证据的病变位置之间的关系，以确定这些关系的性质是否会支持“优势效应”或“病变要么”的解释的两耳分听分数。25名失语症患者完成了我们的数字分听测试，波士顿诊断性失语症检查（BDAE），实验性句子理解测试，和数字即时记忆广度测试。右耳评分（和耳朵优势）准确地反映了除一名患者外的所有患者的中枢听觉结构的完整性，因此被解释为“损伤效应”。“这些相同的右耳分数也与BDAE的短语重复子测试的表现和我们的句子理解测试的分数比其他分析的语言测量更密切相关。这些关系保持即使在一般措施的听觉理解和即时记忆保持不变，通过使用偏相关。“显性”和“病变”效应的解释进行了讨论，但“病变效应”的解释更充分的特点的数据。也就是说，完整的后，上级颞区似乎是必不可少的知觉右耳刺激的数字两分测试和准确的性能在特定的语言测试。
This investigation sought to identify relations between dichotic listening performance and both specific language functions and CT scan evidence of lesion location in order to determine whether the nature of these relations would support either "dominance effect" or "lesion either" interpretations of the dichotic scores. Twenty-five aphasic patients completed our digit dichotic listening test, theBoston Diagnostic Aphasia Examination(BDAE), an experimental sentence comprehension test, and a digit immediate memory span test. Right ear scores (and the ear advantage) accurately reflected the integrity of the central auditory structures for all but one of the patients, and thus were interpreted as "lesion effects." These same right ear scores also were related more strongly to performance on phrase repetition subtests of the BDAE and to scores obtained on our sentence comprehension test than to the other language measures analyzed. These relations were maintained even when general measures of auditory comprehension and immediate memory were held constant through the use of partial correlations. Both "dominance" and "lesion" effect interpretations were discussed, but the "lesion effect" interpretation more adequately characterized the data. That is, the integrity of the posterior, superior temporal area seemed to be essential for perception of right ear stimuli on the digit dichotic test and for accurate performance on specific language tests.
