The objectives of this study are twofold. First, it aims to measure whether information presentation format and task characteristics affect the accuracy and speed of decision-making performance. Second, it aims to determine whether information users have the ability to select an information presentation format that corresponds to the content and complexity of the task. To achieve these two research objectives, a posttest-only true experimental design was conducted in a laboratory setting. The results of hypothesis testing using multivariate analysis of variance (MANOVA) showed that information presentation format did not produce significant differences in the quality of decision-making regardless of task content and complexity. Subjects selected information presentation formats corresponding to task content. However, subjects were unable to select information presentation formats corresponding to task complexity.
