A HyperCard-based tool for studying cognitive processes in complex problem solving

A computer-based system for research in decision making, based on the concept of human problem solvers as builders and users of mental models, is described. This description is presented in three sections: (1) an overview of the behaviors that constitute the cornerstones of human problem solving in realistically complex domains; (2) a brief discussion of the substantive domain selected for studying these behaviors (financial problem solving), detailing the rationale behind its selection; and (3) a comprehensive description of the computerized decision-making system itself. The merits of using HyperCard in such research are discussed in terms of the efficacy and type of data collection engendered.
