Towards Characters With A Dynamic Model of Social Identity

In this work we propose a dynamic agent-based model of social identity, named IDeA, whichis capable of creating characters that have an improved ability to handle and comprehend thesocial context in which a game situation takes place as well as the social identities involvedin that context. The model explores how a character can use identity processes that aregrounded on the social sciences literature as a tool for behaviour selection and filtering. Asa result, characters will choose to adopt different identities dependent on their resources andgoals as well as the relevant features of the contexts in which they find themselves in. A simpledemonstrator application was implemented using our model to illustrate how a charactercan make different decisions in the same game scenario. Using the implemented demonstrator,a study was conducted where participants observed and judged how the characterbehaves in different conditions regarding the context of the situation. The results obtainedrevealed the presence of a dominant identity among the alternatives.
