Abstract

Repetition of the same vocal stimulus during vocal learning may result in habituation. Therefore, selection may favor vocal tutors that produce vocal stimuli with characteristics that reduce the risk of habituation. Superb fairywren Malurus cyaneus mothers produce a two‐element (A and signature B) call to embryos, but embryos only produce one element type (B) after hatching. Why do mothers use the A element to embryos? We broadcast calls with one (B) or two (AB) element types and measured embryo response. Embryos habituated to calls with one element type and remained responsive to calls with both. We conclude that signal characteristics in tutors may guide learning to retain pupil attention during learning.

母鸟巢内鸣叫结构可降低鸣禽胚胎的习性风险

在发声学习过程中，重复相同的发声刺激可能会导致习惯化。因此，选择可能会偏向于产生具有降低习惯化风险特征的声音刺激的声音导师。超级仙女鸦（Malurus cyaneus）的母鸦会对胚胎发出双元素（A 和特征 B）的叫声，但胚胎在孵化后只会发出一种元素（B）。为什么母鸟对胚胎使用 A 要素？我们播放了含有一种（B）或两种（AB）元素类型的叫声，并测量了胚胎的反应。胚胎习惯了一种元素类型的呼唤，并对两种元素类型的呼唤都有反应。我们的结论是，导师的信号特征可能会引导学习，从而在学习过程中保持学生的注意力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
