圈养动物的刻板印象行为被认为是从受挫的自然行为模式中产生的，被认为在圈养动物中更常见。然而，关于形成刻板印象的早期阶段的数据目前很少。我们首次比较了人工饲养的八哥和放在单独笼子里的野生八哥的刻板路线跟踪和翻筋斗的发展。我们发现，被野生捕获的鸟类不那么活跃，但表现出更多的逃跑动机和更多的路线追踪行为的证据。此外，只有在野外捕获的鸟类中才能观察到翻筋斗。在笼子里的最初几天里，通过行为的细微差异来预测翻筋斗的发生，并在路线追踪行为水平较低的个体中发生。我们的数据表明，逃避动机在八哥刻板印象的发展中扮演了一个角色，此外，路线追踪和翻筋斗可能是受阻逃避的替代出路。与哺乳动物的观察结果相反，我们的结果表明，在野生捕获的八哥中，刻板印象更常见。(C)2011年威利期刊公司开发心理学杂志54：773784,2012年
Stereotypic behavior in captive animals has been hypothesized to emerge from thwarted natural behavior patterns and is thought to be more common in captive-reared animals. However, data on the early stages of developing stereotypies are currently scarce. We compared the development of stereotypic route-tracing and somersaulting in hand-reared and wild-caught starlings placed in individual cages for the first time. We found that wild-caught birds were less active but showed more escape motivation and more evidence of route-tracing behavior. Furthermore, somersaulting was only observed in wild-caught birds. Development of somersaulting was predicted by subtle differences in behavior during the first few days in cages and developed in individuals with low levels of route-tracing behavior. Our data suggest a role for escape motivation in the development of starling stereotypies and additionally that route-tracing and somersaulting may represent alternative outlets for thwarted escape. In contrast to observations from mammals, our results show that stereotypies are more common in wild-caught starlings. (C) 2011 Wiley Periodicals,Inc. Dev Psychobiol 54: 773784, 2012
