The Psychology Chapter of the International System Dynamics Society was formed about a year and a half ago. In general, the goals of the chapter are to integrate relevant psychological concepts into System Dynamics models and to apply System Dynamics methodology to model individual and social psychological theories, by introducing feedback mechanisms as underlying causes of behavior. The Chapter currently is in its early stages of development. There are plans to survey the System Dynamics literature to find how others in the past have included psychological processes in their models. In addition, a list serve will be established for its members to share ideas about modeling psychological processes and to discuss behavioral principles might be needed to make some System Dynamics models more attuned to the current psychological literature. In the meeting in Boston, we will begin the process of writing the Chapter's bylaws, which eventually should lead to election of officers.
