From individual models of attitude change to patterns and dynamics of opinion landscapes — •Jan Lorenz — Uni Bremen, Bremen, Germany — Jacobs University, Bremen, Germany

We model the dynamics of attitude formation through social interaction in a large society. We consider attitudes on a one dimensional scale which represents either emotional valence towards a certain object or concept (e.g. "How good or bad is religion?"), the degree to which a certain value is important for a person, political left-right selfplacement, or adherence to certain social norms (e.g. "Murder is to be punished with death."). Individual attitude change during interaction with others is modeled with respect to a reinforcement theory, an information processing theory, a social judgment theory, and a polarity effect. We will answer the questions to what extend these indivual mechanisms contribute to the societal phenomena of extremal consensus, moderate consensus, polarization, fractionalization, maintenance of diversity, and cyclic behavior.
