Two groups of brain damaged adults, those with cerebrocranial injury (CCI) and victims of cerebrovascular accident (CVA) were tested with the competing sentences test of Willeford (In: Central Auditory Dysfunction. New York: Grune and Stratton, 1977: Chap 2). The main purpose was the exposure of functional disorders of communication in such patients who test within normal or near-normal limits on routine audiological testing and also on tests for aphasia. Of 142 serially admitted CCI patients, 43%, many with diffuse lesions, gave abnormal responses, mostly at the left ear, with 19 of them showing total extinction at that ear. On two sound field competing message tests the CCI patients were significantly poorer than normal controls. CVA patients with confirmed right hemisphere lesions tended strongly toward left ear suppression, while left hemisphere damaged patients often showed bilateral drop in scores. It is clear that brain damaged patients can have central dysfunction of auditory processing despite normal findings on routine audiological tests and tests for aphasia. The implications for activities of daily living and for habilitation are discussed.
两组脑损伤成年人，即颅脑损伤（CCI）患者和脑血管意外（CVA）患者，接受了Willeford的竞争句子测试（载于《中枢听觉功能障碍》。纽约：格鲁恩与斯特拉顿出版社，1977年：第2章）。主要目的是揭示此类患者在常规听力测试以及失语症测试中结果正常或接近正常的情况下的交流功能障碍。在142例连续收治的CCI患者中，43%的患者（其中许多有弥漫性病变）反应异常，多数发生在左耳，其中19例在该耳表现为完全消音。在两项声场竞争信息测试中，CCI患者明显比正常对照组差。确诊为右半球病变的CVA患者强烈倾向于左耳抑制，而左半球受损的患者往往双侧得分下降。显然，尽管在常规听力测试和失语症测试中结果正常，但脑损伤患者仍可能存在听觉处理中枢功能障碍。文中还讨论了其对日常生活活动和康复训练的影响。
