通过社会学习产生和传播的新行为可以导致人口水平的迅速变化，从而使个人之间的社会联系塑造信息流。然而，行为可以通过不同的机制传播，人们对信息流如何取决于个人使用的基本学习规则知之甚少。在这里，比较四种不同的学习机制，我们模拟行为传播复制经验的社交网络的野生大山雀，并探讨了个体的社会性和行为收购的顺序之间的关系。我们的研究结果表明，学习规则依赖于社会联系的总和和强度，以知情的个人，社会连接与收购的顺序，与个人增加社会连接和减少社会集群采用新的行为更快。然而，当行为采纳取决于一个人的社会联系的比例，知情与不知情的个人，社会连接是不相关的收购顺序。最后，我们展示了特定的学习机制如何限制网络内的行为传播。这些发现对于理解行为是否以及如何在社会系统中传播，个人的社会性和行为习得之间的关系，以及社会性的成本和收益具有重要意义。
The emergence and spread of novel behaviours via social learning can lead to rapid population-level changes whereby the social connections between individuals shape information flow. However, behaviours can spread via different mechanisms and little is known about how information flow depends on the underlying learning rule individuals employ. Here, comparing four different learning mechanisms, we simulated behavioural spread on replicate empirical social networks of wild great tits and explored the relationship between individual sociality and the order of behavioural acquisition. Our results reveal that, for learning rules dependent on the sum and strength of social connections to informed individuals, social connectivity was related to the order of acquisition, with individuals with increased social connectivity and reduced social clustering adopting new behaviours faster. However, when behavioural adoption depends on the ratio of an individuals’ social connections to informed versus uninformed individuals, social connectivity was not related to the order of acquisition. Finally, we show how specific learning mechanisms may limit behavioural spread within networks. These findings have important implications for understanding whether and how behaviours are likely to spread across social systems, the relationship between individuals’ sociality and behavioural acquisition, and therefore for the costs and benefits of sociality.
