This article describes an experiment that examined the effects of two versus three-dimensional graphs for two modes of information presentation, paper or computer, for a managerial decision-making problem. The effects of these variables on the problem solving strategies and cognitive styles of experienced and non-experienced decision makers were also examined. The experimental results indicated that solution times were faster for computer than for paper presentations of information, no significant effects for dimensionality were found, and there was no significant correlation between solution time and cognitive styles (visual acuity, Myers-Briggs test) across modes of information presentation.
