基于群体内外互动的社会规范共存
Coexistence of Social Norms based on In- and Out-group Interactions
摘要：
社会规范如何从个体之间的微观互动中产生的问题是社会科学解释集体行为的一个关键问题。在本文中，我们提出了一个基于代理的模型表明，随机分布的社会行为，通过本地的互动收敛到一个多模态分布的行为状态。这可以解释为不同社会规范的共存，这一结果超出了以往的调查。该模型在时间和空间上是离散的，行为特征在连续的状态空间中。每个代理人的社会行为的适应是基于代理人之间的友好和敌对关系所引起的吸引力和排斥力。该模型进行了分析，并通过时空计算机模拟。它提供了条件，在这些条件下，我们可以找到向单一规范的趋同，两种对立规范的共存，以及多种规范的共存。对于后者的情况下，我们还显示了行为的时空分布的演变。
英文摘要：
The question how social norms can emerge from microscopic interactions between individuals is a key problem in social sciences to explain collective behavior. In this paper we propose an agent-based model to show that randomly distributed social behavior by way of local interaction converges to a state with a multimodal distribution of behavior. This can be interpreted as a coexistence of different social norms, a result that goes beyond previous investigations. The model is discrete in time and space, behavior is characterized in a continuous state space. The adaptation of social behavior by each agent is based on attractive and repulsive forces caused by friendly and adversary relations among agents. The model is analyzed both analytically and by means of spatio-temporal computer simulations. It provides conditions under which we find convergence towards a single norm, coexistence of two opposing norms, and coexistence of a multitude of norms. For the latter case, we also show the evolution of the spatio-temporal distribution of behavior.
