In this study, a user experiment was conducted to investigate the effects of information presentation factors (modality and structure) on decision making behavior, using a time-limited task. The time constraint required subjects to develop heuristic strategies to substitute the defined normative strategy. The two presentation factors have been shown to significantly affect the decision making performance, assessed by time efficiency and efficiency, due to its impact on the efficiency of information perception. By analyzing the subjective reports and the error distribution, the structure was shown to influence the selection of heuristic strategies. Consequentially, it affected both the time efficiency and the accuracy of decision making. The interaction between the time constraint and the presentation effects was also observed.
