An Investigation Of The Effects Of Decisional Guidance And Cognitive Ability On Decision-Making Involving Uncertainty Data
Cognitive fit; Decisional guidance; Display format; Uncertainty
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 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. We 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. We 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. When decisional guidance restricted the display formats to match the task types, field dependency did not significantly affect performance. This suggests that cognitive ability or field dependency is not factor when the mental representation formulated is consistent with the problem representation. © 2002 Elsevier Science Ltd.
