ABSTRACT: This talk will present models for the evolution of opinions, interpersonal influences, and social power in a group of individuals. I will present empirical data and mathematical models for the opinion formation process in deliberative groups, including concepts of self-weight and social power. I will then focus on groups who discuss and form opinions along sequences of judgemental, intellective, and resource allocation issues.  I will show how the natural dynamical evolution of interpersonal influence structures is shaped by the psychological process of reflected appraisal. Multiagent models and analysis results are grounded in influence networks from mathematical sociology, replicator dynamics from evolutionary games, and transactive memory systems from organization science.
