| Abstract: | In their roles as users and providers of uncertainty data, decision-makers are confronted with choosing among a plethora of data formats offered by the decision support systems on most personal computers, but are offered little in the way of decisional guidance for choosing the most effective display format. This research investigated when and why decisional guidance should be provided. The authors found that in tasks involving uncertainty data, the decision-makers were more accurate and responded faster when symbolic tasks were matched with tabular displays and spatial tasks were matched with graphical displays. The authors also found that when subjects were provided with both matched and unmatched display formats, field independent individuals were more accurate for both spatial and symbolic tasks. |
