This study examines the impact of heuristic-based approaches to the acquisition of task-related information on the selection of an optimal alternative during a simulated in-flight decision-related task. Features of naturalistic and normative decision making and strategies of information acquisition were integrated within a computer-based, decision support framework. The study comprised two phases. The first phase was designed to provide pilot participants with an opportunity to engage each of three heuristic-based strategies of information acquisition: frequency, elimination by aspects, and majority of confirming decisions. The second stage enabled participants to choose one of the three strategies of information acquisition to resolve a fourth (choice) scenario. The results indicated that task-oriented experience, rather than the information acquisition strategies, predicted the selection of the optimal alternative. The elimination by aspects information acquisition strategy was preferred by most participants over the other two strategies. These findings can be used in the development of decision support systems that adapt to user information processing capabilities and preferences.
