    Providing Battlespace Information to Reduce Uncertainty: Will More Information Lead to Better Plans?2008In: Journal of Cognitive Engineering and Decision Making, ISSN 1555-3434, E-ISSN 2169-5032, Vol. 2, no 4, p. 295-310Article in journal (Refereed)
    Abstract [en]

    One basic assumption behind network-centric warfare (NCW) is that increased supply of information will reduce battlespace uncertainty and increase decision quality. The purpose of this study was to test this assumption. Swedish army captains formed 16 brigade-level planning teams and performed in a realistic planning task. Eight teams planned with access to NCW-similar (abundant) information on the enemy situation, and 8 teams planned using the information supply of today. Results showed a significant reduction in perceived uncertainty for the NCW-condition teams but no substantial differences in plan quality, plan confidence, plan variability, or planning time between the two conditions. These results indicate that even though more information may result in less perceived uncertainty among future military decision makers, an increased information supply needs to be coupled with changes in doctrine and training to provide a maximum benefit to the military planner.

    Visualizing a time-space constraint increases performance in a dynamic search task2010In: Journal of Cognitive Engineering and Decision Making, ISSN 1555-3434, E-ISSN 2169-5032, Vol. 4, no 4, p. 275-287Article in journal (Refereed)
    Abstract [en]

    This article presents a display manipulation designed to support search tasks in which the location of the target is unknown and changes over time. The problem is analogous to that of a naval search task when there is an initial sighting and then the naval force must guide its search vehicles to reestablish contact with the fleeing target. The display manipulation visualizes a dynamic constraint on the area where a fleeing target can be found and adjusts its shape to the environment and to the search efforts. Forty participants without prior knowledge of search tactics completed 12 trials in an experiment that compared performance with and without the visualization aid and controlled for learning effects. The results suggest that this visualization improves performance in the dynamic search task. They further suggest that the visualization was easy to learn but that the learning effect did not transfer to a condition without visualization. The results have practical utility for both military and civil search tasks, and they are consistent with other research that emphasizes that control interfaces should make constraints in the task environment perceptually available.
