Previous research showed that chronic testosterone treatment of adult female canaries results in song development, demonstrating that vocal behavior is more dependent upon the presence of an appropriate hormonal stimulus than upon the genetic sex of the individual. We now report that in adult female canaries the importance of the left hemisphere for controlling testosterone induced song increases with singing experience. The occurrence of left-lateralized control of vocal behavior may prove to be a characteristic typical of animals capable of vocal learning.
先前的研究表明，对成年雌性金丝雀进行长期睾酮治疗会导致其歌声发育，这表明发声行为更多地依赖于适当激素刺激的存在，而非个体的遗传性别。我们现在报告，在成年雌性金丝雀中，左半球对控制睾酮诱导的歌声的重要性会随着歌唱经验的增加而增强。发声行为左侧化控制的出现可能被证明是能够进行发声学习的动物的典型特征。
