刻板印象是重复的，一成不变的和无目标的行为模式，通常被认为是圈养动物福利差的标志。对陈规定型观念进行量化可能很困难，特别是在其发展的早期阶段，那时行为还很灵活。我们比较了两种方法，客观地量化发展的路线跟踪刻板在笼八哥。我们使用马尔可夫链和T模式分析（由软件包Theme实现）来识别鸟在笼子里占据的位置序列中的模式。这两种方法产生的模式指标与频率的既定措施的刻板行为和异常行为模式计数的视频记录，这表明这两种方法可能是有用的，以确定刻板的个人和量化刻板行为。我们讨论了这两种方法的相对优点和缺点。(C)2009 Elsevier B.V.保留所有权利。
Stereotypies are repetitive, unvarying and goalless behaviour patterns that are often considered indicative of poor welfare in captive animals. Quantifying stereotypies can be difficult, particularly during the early stages of their development when behaviour is still flexible. We compared two methods for objectively quantifying the development of route-tracing stereotypies in caged starlings. We used Markov chains and T-pattern analysis (implemented by the software package, Theme) to identify patterns in the sequence of locations a bird occupied within its cage. Pattern metrics produced by both methods correlated with the frequency of established measures of stereotypic behaviour and abnormal behaviour patterns counted from video recordings, suggesting that both methods could be useful for identifying stereotypic individuals and quantifying stereotypic behaviour. We discuss the relative benefits and disadvantages of the two approaches. (C) 2009 Elsevier B.V. All rights reserved.
