Abstract
Decision making processes can be viewed as a form of problem solving. Approaches to the study of problem solving processes can then be applied to decision making. The approach presented here uses think-aloud protocols as data. A process model is constructed of the data, using the “limited rationality” approach, which assumes that behaviour is rational given constraints imposed by the task, the knowledge that people have and the capacity limits in their cognitive architecture. The method for constructing such models, collecting the think-aloud data and evaluating the model are outlined.
