通过社会学习的新行为的出现和传播可以导致快速的人口水平变化，从而使个体之间的社会联系形成信息流。然而，行为可以通过不同的机制传播，人们对信息流如何依赖于个人使用的潜在学习规则知之甚少。本文通过比较四种不同的学习机制，模拟了野生大山雀在复制经验社会网络上的行为传播，探讨了个体社会性与行为习得顺序之间的关系。我们的研究结果表明，对于依赖于社会联系的总和和强度的学习规则，社会联系与习得顺序有关，社会联系增加和社会聚类减少的个体更快地采用新行为。然而，当行为采用取决于个体与知情个体和不知情个体的社会联系的比例时，社会联系与习得顺序无关。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可能在社会系统中传播、个体社会性和行为习得之间的关系，以及因此对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.
