人格特质与自我网络动力学
Personality Traits and Ego-network Dynamics
摘要：
强大和支持性的社会关系对我们的福祉至关重要。然而，维护它们是有成本的，导致质量和数量之间的权衡，一个典型的策略是在少数高强度关系上投入大量精力，同时维护大量不太密切的关系。研究还表明，在这种模式中存在持续的个体差异;有些人在他们的网络中更均匀地分配他们的努力，而另一些人则强烈关注他们最亲密的关系。此外，有些人比其他人保持更稳定的网络。在这里，我们专注于个人的性格特征如何影响这一画面，使用移动电话通话记录和调查数据从移动领土实验室（MTL）的研究。特别是，我们看看人格特质和（i）社会签名的持久性，即在不同的时间间隔测量的个人的社会签名形状的相似性之间的关系;（ii）在自我中心网络的营业额，即在两个连续的时间间隔存在的改变集的差异;以及（iii）等级动态性，定义为自我中心网络中等级在连续时间间隔内的变化。我们观察到，一些特征的社会签名的稳定性，以及网络营业额和排名动态的影响。例如，在经验开放性特质中得分高的个体往往具有更高的网络周转率和更大的等级变化。从更广泛的角度来看，我们的研究表明，人格特质显然会影响个人维持个人网络的方式。
英文摘要：
Strong and supportive social relationships are fundamental to our well-being. However, there are costs to their maintenance, resulting in a trade-off between quality and quantity, a typical strategy being to put a lot of effort on a few high-intensity relationships while maintaining larger numbers of less close relationships. It has also been shown that there are persistent individual differences in this pattern; some individuals allocate their efforts more uniformly across their networks, while others strongly focus on their closest relationships. Furthermore, some individuals maintain more stable networks than others. Here, we focus on how personality traits of individuals affect this picture, using mobile phone calls records and survey data from the Mobile Territorial Lab (MTL) study. In particular, we look at the relationship between personality traits and the (i) persistence of social signatures, namely the similarity of the social signature shape of an individual measured in different time intervals; (ii) the turnover in egocentric networks, that is, differences in the set of alters present at two consecutive temporal intervals; and (iii) the rank dynamics defined as the variation of alter rankings in egocentric networks in consecutive intervals. We observe that some traits have effects on the stability of the social signatures as well as network turnover and rank dynamics. As an example, individuals who score highly in the Openness to Experience trait tend to have higher levels of network turnover and larger alter rank variations. On broader terms, our study shows that personality traits clearly affect the ways in which individuals maintain their personal networks.
