However, it appears that among different species of close-ended songbirds, there are some variations in the necessity of auditory feedback for maintaining stereotyped adult song. In zebra finches, the deterioration of adult songs following deafness depends on the birds＇ age. It is unknown whether this age effect is a general rule in other avian species as well. Therefore, we chose Bengalese finches, whose songs show more complexity and have much heavier dependency on auditory feedback than that of zebra finches, to compare the degree of song degradation after hearing loss in old （over 18 months old） and young adult birds （5 - 6 months old）. We found that both syllable sequence and syllable phonology were much less severely affected by deafening in old adults than that in young ones. Moreover, young adults almost lost their capability to sing trills over 6 months following deafening, while old birds continued to sing plenty of trills and trilled syllables after the same period of deafening. Our results suggest that age plays an important role in affecting the dependency of adult song maintenance on auditory feedback in Bengalese finches. Furthermore, the age dependency may be a general phenomenon in different species of close-ended songbirds [ Current Zoology 55 （3）： 212 - 218, 2009].展开更多
目的探讨语后聋成人人工耳蜗使用者感知音乐音调的能力。方法使用慕尼黑音乐经验问卷(Munich music questionnaire,MUMU)评估12例听力正常受试者(听力正常组,男5例,女7例)与12例人工耳蜗使用者(人工耳蜗组,男5例,女7例)的年龄与音乐经...目的探讨语后聋成人人工耳蜗使用者感知音乐音调的能力。方法使用慕尼黑音乐经验问卷(Munich music questionnaire,MUMU)评估12例听力正常受试者(听力正常组,男5例,女7例)与12例人工耳蜗使用者(人工耳蜗组,男5例,女7例)的年龄与音乐经验的匹配程度。使用Fitzgerald等开发的人工耳蜗音乐评估软件(MuSIC)中的音调辨差阈值测试、旋律辨别与和弦辨别测试评估人工耳蜗使用者的音乐音调感知能力。结果听力正常组与人工耳蜗组的年龄与音乐经验相匹配。人工耳蜗组F3调的音调辨差阈值平均为16.2个1/4音,C4调的音调辨差阈值平均为6.2个1/4音,均显著高于听力正常组(P<0.05)。人工耳蜗组的旋律辨别测试平均正确率为69.8%,和弦辨别测试的平均正确率为72.4%,与听力正常组比较差异无统计学意义(P>0.05)。人工耳蜗组耳蜗植入前助听器使用时间与其植入后聆听音乐的经验均与其音调辨差阈值显著相关(P<0.05)。结论语后聋成人人工耳蜗使用者的音调辨差阈值显著高于听力正常人,但个体差异较大,其音乐音调感知能力与人工耳蜗植入前助听器佩戴时间以及植入后聆听音乐的经验相关。展开更多
