Tests of central auditory function were performed variously on 64 patients with hemiplegia who had suffered a single stroke but with minimal or no aphasia symptoms and with essentially normal hearing. Both right and left hemisphere lesions were represented for comparison of effects on the tests. Reports of central auditory dysfunction generally assume localization in the temporal lobes. Since it was apparent that our tests were revealing positive findings in patients in whom there was no recognized evidence of temporal lobe involvement we deliberately selected for one study 34 patients without clinical signs of such lesions. The tests required selective listening in which patients had to a) perceive and repeat a prime message in the presence of a simultaneously competing meaningful message, either under earphones or in the sound field (loudspeaker), and b) repeat all words in a classic dichotic listening task. The tests reveal different dysfunctions in right vs left hemisphere damage and document that compensatory transfer of function from the usually dominant left side to the fight hemisphere usually occurs only in young children. The dysfunctions appear to be unrelated to temporal lobe lesions.
对64例偏瘫患者进行了多种中枢听觉功能测试，这些患者均为单次中风，失语症状轻微或无失语症状，听力基本正常。研究纳入了右侧和左侧半球病变的患者，以比较病变对测试结果的影响。关于中枢听觉功能障碍的报告通常认为病变定位于颞叶。由于很明显我们的测试在那些没有公认的颞叶受累证据的患者中发现了阳性结果，我们特意挑选了34例没有此类病变临床体征的患者进行一项研究。这些测试需要选择性听力，即患者必须：a）在同时存在竞争性有意义信息的情况下，通过耳机或在声场（扬声器）中感知并重复主要信息；b）在经典的双耳分听任务中重复所有单词。测试揭示了右侧与左侧半球损伤的不同功能障碍，并证明功能通常从占主导地位的左侧向右侧半球的代偿性转移通常仅发生在幼儿中。这些功能障碍似乎与颞叶病变无关。
