AN EXPERIMENTAL PROGRAM INVESTIGATING COLOR-ENHANCED AND GRAPHICAL INFORMATION PRESENTATION - AN INTEGRATION OF THE FINDINGS

A series of three laboratory experiments were conducted to assess the influence of graphical and color-enhanced information presentation modes on decision quality, decision-making time, use of information, and user perceptions. The experimental design allowed for the unconfounded study of line graphs and color using a variety of information presentation designs for the same decision-making task. Based on the findings of these studies, propositions about the impact of graphics and color on individual decision-makers are presented. The influence of presentation mode on human performance and the perceived value of information is found to be related to how well it supports the solution approach to a particular task.
