行为表型可以从多种角度进行研究。最近的发展集中在个体上，寻求随时间和/或跨不同环境(动物个性)稳定的行为模式。这项研究将这种理解个体行为变异性的方法应用于家养豚鼠。调查了两个行为领域：情绪性和社会行为。此外，还检查了个体的皮质醇应激反应和显性状态。成年雄性家养豚鼠生活在大的混合性别群体中，进行了两次一系列的行为和生理测试，测试间隔为8周。在社交行为、皮质醇反应性和支配地位方面，个体随着时间的推移而保持一致，而在情绪行为方面则没有检测到稳定性。此外，没有发现对上下文的稳定性。我们的结果表明动物人格的概念适用于家养豚鼠。这些数据是从非常丰富的、复杂的社会场景中从动物身上获得的，这一事实突显了这些数据的生态相关性。此外，我们的研究强调，行为本身不足以描述个体的表型一致性。应激反应等生理参数应包括在动物个性研究中。此外，支配地位--一种不是个人绝对属性的相对衡量标准--被证明随着时间的推移是稳定的，因此也揭示了个性。
Behavioural phenotypes can be studied from a variety of perspectives. Recent developments have focused on the individual, seeking patterns of behaviour that are stable over time and/or across different contexts (animal personalities). This study applied this method of understanding individual behavioural variability to domestic guinea pigs. Two behavioural domains were investigated: emotionality and social behaviour. Additionally, individual cortisol–stress reactivity and dominance status were examined. Adult male domestic guinea pigs living in large mixed‐sex colonies were subjected to a series of behavioural and physiological tests twice with an intertest interval of 8 wk. Individual consistency over time was found regarding social behaviour, cortisol reactivity and dominance status, whereas no stability regarding emotional behaviour was detected. Furthermore, no stability over contexts was found. Our results suggest that the concept of animal personality is applicable to domestic guinea pigs. The ecological relevance of these data is underscored by the fact that they were obtained in animals from a very rich, socially complex scenario. Moreover, our study highlights that behaviour alone is not sufficient to describe individual phenotypic consistency. Physiological parameters such as stress reactivity should be included in animal personality research. Furthermore dominance – a relative measure which is not an absolute attribute of individuals – proved to be stable over time and thus also shed light on individuality.
