摘要
个体会随着社会环境的变化而改变自己。换句话说,一个人的身份是动态的,根据上下文(例如,个人在场、地点、任务)而变化。身份对一个人的行为有重大影响。研究人员一直感兴趣的是了解背景因素如何塑造身份,以及身份如何影响行为。基于代理的仿真模型是识别和预测与这些身份过程相关的行为的重要工具。此外,代理可以利用基于社会理论的身份相关机制,变得更具有社会可信度和与人类相似。社会认同方法(SIA)是涵盖个人身份的社会方面的最具影响力的理论之一,其许多概念被应用于社会模拟研究。本文形式化了基于SIA的基于agent的动态身份模型(Dynamic Identity Model for Agents, DIMA),提供了该模型的详细理论基础,并概述了其作为一个组件集成到社会agent体系结构中的情况。在DIMA中,行动者要么将自己视为独特的个体(个人身份),要么将自己视为社会群体的成员(社会身份),根据他们依赖于情境的主动身份行事。这里提供了两个模拟场景来说明该模型的使用,一个基于独裁者游戏,另一个基于垃圾收集任务。这项工作旨在指导其他想要用DIMA的身份突出机制来增强其代理人的研究人员。因此,他们不仅能够评估这种机制如何根据情境影响行为,而且还能够探索个人身份和社会身份之间的动态关系。
When "I" Becomes "We": Modelling Dynamic Identity on Autonomous Agents
: Individuals change who they are in response to their social environment. In other words, one’s identityisdynamic,varyingaccordingtocontext(e.g.,individualspresent,place,task). Identityhasasignificant impact on an individual’s behaviour. Researchers have been interested in understanding how contextual aspects shape identity and, in turn, how identity influences behaviour. Agent-based simulation models are great tools to identify and predict behaviour associated with these identity processes. In addition, agents can employ identity-related mechanisms based on social theories to become more socially believable and similar to humans. The Social Identity Approach (SIA) is one of the most influential theories covering social aspects of one’s identity, with many of its concepts being applied in social simulation research. This paper formalizes the Dynamic Identity Model for Agents (DIMA), an existing agent-based model based on SIA, providing a detailed theoretical foundation of the model, as well as an overview of its integration as a component into a social agent architecture. In DIMA, agents perceive themselves either as distinct individuals (personal identity) or as members of a social group (social identity), acting according to their context-dependent active identity. Two simulation scenarios are presented here to illustrate the use of this model, one based on the Dictator Game and the other on a trash collection task. This work aims to guide other researchers who want to enhance their agents with the DIMA’s identity salience mechanism. As a result, they would not only be able to assess how this mechanism influences behaviour based on the context, but they would also be able to explore the dynamics between personal and social identities.
期刊介绍:
The Journal of Artificial Societies and Social Simulation is an interdisciplinary journal for the exploration and understanding of social processes by means of computer simulation. Since its first issue in 1998, it has been a world-wide leading reference for readers interested in social simulation and the application of computer simulation in the social sciences. Original research papers and critical reviews on all aspects of social simulation and agent societies that fall within the journal"s objective to further the exploration and understanding of social processes by means of computer simulation are welcome.
