在鸣禽中，学习唱歌是一个高度社会化的过程，可能涉及社会奖励。在这里，我们测试了一个假设，即在歌曲学习过程中，听到特定歌曲的奖励值预测了该歌曲最终被学习的程度。我们测量了早期的歌曲偏好的年轻男性斑胸草雀（Taeniopygia guttata）在操作性按键测定;每两个键与更高的可能性播放的歌曲的父亲或另一个熟悉的成年人（“邻居”）。为了最大限度地减少暴露对学习的影响，我们实施了一种新的强化计划，使我们能够在平衡每首歌曲的暴露的同时检测偏好。平均而言，青少年显着更喜欢父亲的歌曲在歌曲学习早期，在实际的歌唱发生在这个物种。当它们成年后，所有的鸟都模仿父亲的歌声。父亲的歌曲被模仿的准确性与歌曲学习的敏感期对父亲歌曲的偏好的峰值强度呈正相关。我们的研究结果表明，偏好的歌曲选择的导师，在这种情况下，父亲，预测声乐学习过程中的发展。
In songbirds, learning to sing is a highly social process that likely involves social reward. Here, we tested the hypothesis that during song learning, the reward value of hearing a particular song predicts the degree to which that song will ultimately be learned. We measured the early song preferences of young male zebra finches (Taeniopygia guttata) in an operant key-pressing assay; each of two keys was associated with a higher likelihood of playing the song of the father or that of another familiar adult (“neighbor”). To minimize the effects of exposure on learning, we implemented a novel reinforcement schedule that allowed us to detect preferences while balancing exposure to each song. On average, the juveniles significantly preferred the father’s song early during song learning, before actual singing occurs in this species. When they reached adulthood, all the birds copied the father’s song. The accuracy with which the father’s song was imitated was positively correlated with the peak strength of the preference for the father’s song during the sensitive period of song learning. Our results show that preference for the song of a chosen tutor, in this case the father, predicted vocal learning during development.
