最近在几个物种中发现了同种动物对声音学习的积极指导，包括一些鲸目动物和灵长类动物。然而，在斑胸草雀，Taeniopygia guttata，一种通常被研究的鸣禽中，声音学习传统上被认为是记忆和模仿歌曲模型的产物。直到最近，特定的社会反馈线索才被证明可以增强歌曲学习。是什么机制推动了与社会互动相关的上级学习？我们最近发现，“绒毛”，一个非声乐女性唤醒线索，促进歌曲学习时，播放视频偶然对青少年的歌曲生产在整个发展。然而，目前尚不清楚成年人是否会自然地对不成熟的歌曲做出偶然的反应，以及年轻的雀是否会将自然发生的反馈纳入歌曲学习。为了调查社会影响是否影响歌曲学习，本研究探讨了与歌曲发展相关的母亲和父亲线索的性质和意义。我们记录未操纵的斑马雀家庭在整个青少年的发展和分析他们的社会互动。我们发现，父母双方的行为与后代的歌曲结果有关。青少年的歌曲学习可以通过他们在整个发展过程中从母亲那里获得的偶然的“蓬松”行为来预测。父亲经常唱后立即少年唱了，和父亲的歌唱后少年歌唱与更准确的歌曲学习在他们的儿子呈正相关。相反，当父亲唱之前，少年唱，少年学歌不太准确。我们的数据表明，父母的声音和手势反馈在斑胸草雀的歌曲学习中起着加强的作用。有许多非鸟类物种，包括翼手目，厚皮动物和鳍足类，修改他们的发声在不同的发展或社会背景，但其发声学习的机制是未知的。我们的研究结果表明，这些物种应该仔细检查成人的敏感性不成熟的发声和发展能力，从社会反馈中学习。(c)2020动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Active guidance of vocal learning by conspecifics has recently been found in several species, including some cetaceans and primates. However, in the zebra finch, Taeniopygia guttata, a commonly studied songbird, vocal learning was traditionally considered the product of memorization and imitation of a song model. Only recently have specific social feedback cues been shown to enhance song learning. What mechanisms drive the superior learning associated with social interactions? We recently found that 'fluff-ups', a nonvocal female arousal cue, facilitated song learning when played over video contingently on juvenile song production throughout development. However, it is unknown whether adults naturally respond in a contingent fashion to immature song, and whether young finches incorporate naturally occurring feedback into song learning. To investigate whether social influences affect song learning, the present study addressed the nature and significance of maternal and paternal cues associated with song development. We recorded unmanipulated zebra finch families throughout juvenile development and analysed their social interactions. We found that behaviours of both parents were associated with offspring song outcomes. Juvenile song learning could be predicted by the amount of contingent 'fluff-up' behaviours they received from their mothers throughout development. Fathers often sang immediately after a juvenile had sung, and paternal singing after juvenile singing was positively correlated with more accurate song learning in their sons. Conversely, when fathers sang before the juvenile sang, juveniles learned song less accurately. Our data suggest that parental vocal and gestural feedback plays a reinforcing role for song learning in zebra finches. There are many nonavian species, including chiropterans, pachyderms and pinnipeds, that modify their vocalizations in different developmental or social contexts but whose mechanisms of vocal learning are not known. Our findings suggest that these species should be closely examined for adult sensitivity to immature vocalizations and developmental capacity to learn from social feedback.
