Representational effects on the solving of an unstructured decision problem

The use of graphic problem representations in problem structuring or formulation is considered, as well as the potential effects of incomplete representations on problem solving. Empirical results suggest that humans cannot reliably identify key problem elements and that the availability of incomplete graphic depictions can constrain the scope of problem-solving activity, harming overall performance. The nature of these process effects is investigated, with implications being drawn for decision-aiding practice. The analysis of how the adverse performance effects occur is shown to have significant implications for decision analysis, decision-support systems and other decision-aiding technologies
