敏感期是鸣禽听觉学习的一个特殊时期。然而，很少有人知道的感知和歧视的歌曲在这一时期的发展。作者使用了去/不去操作性任务，比较歧视同种歌曲从反转的歌曲在少年和成年斑马firiches（Taeniopygia guttata），并测试可能的发展变化的感知音节结构和音节句法。在实验1中，有没有年龄或性别差异的能力，学习的歧视，和鸟类歧视的基础上，主要是当地的音节结构的正向和反向的歌曲。在实验2中发现了类似的结果，幼鸟饲养隔离的歌曲。实验三发现，幼年斑胸草雀可以根据音节顺序单独辨别歌曲，尽管这种辨别比基于音节结构的辨别更困难。结果显示，即使是对歌曲没有什么经验的斑胸草雀，其幼雀也具有发达的歌曲辨别和歌曲感知能力。
The sensitive period is a special time for auditory learning in songbirds. However, little is known about perception and discrimination of song during this period of development. The authors used a go/no-go operant task to compare discrimination of conspecific song from reversed song in juvenile and adult zebra firiches (Taeniopygia guttata), and to test for possible developmental changes in perception of syllable structure and syllable syntax. In Experiment 1, there were no age or sex differences in the ability to learn the discrimination, and the birds discriminated the forward from reversed song primarily on the basis of local syllable structure. Similar results were found in Experiment 2 with juvenile birds reared in isolation from song. Experiment 3 found that juvenile zebra finches could discriminate songs on the basis of syllable order alone, although this discrimination was more difficult than one based on syllable structure. The results reveal well-developed song discrimination and song perception in juvenile zebra finches, even in birds with little experience with song.
