人格研究中一个很大程度上被忽视的领域是一个人与他人一起行动和吃饭的倾向。我们使用PIT-tag系统监测了圈养斑胸草雀在大型围场中社会群体中的觅食行为，并单独分析了与社会伙伴一起在家庭笼子中的活动水平。我们发现，更活跃的个体更快地找到新的喂食者（探索得更快）。此外，我们发现更活跃的雄性比不活跃的雄性更少社交。我们的研究结果表明，斑胸草雀觅食行为的变化是由个性和社会因素共同驱动的。这项研究表明，社会性程度——个体与其他同类互动和协调活动的内在倾向——是人格的一个重要组成部分，需要在未来的工作中加以考虑。
One largely neglected area of personality research is an individual’s propensity to move and feed alongside others. We monitored the foraging behaviour of captive zebra finches in social groups in large enclosures using a PIT-tag system, and also separately assayed activity levels in a home cage with a social partner. We found that more active individuals found novel feeders more quickly (explored faster). Furthermore, we found that more active males fed less socially than inactive males. Our findings suggest that variation in foraging behaviour in the zebra finch is driven by both personality and social factors. This work suggests that degrees of sociality — the intrinsic propensity with which individuals interact and coordinate their activity with other conspecifics — is an important component of personality, and needs to be accounted for in future work.
