Barnett, Barbara J. (1993): Perspectives on Decision Analysis for Decision Support System Design. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. p. 1101.

“This symposium addresses the characterization of human decision making within a complex environment for the purpose of developing improved decision support systems. All of the work presented in this symposium was conducted under a Navy research program entitled "Tactical Decision Making Under Stress" (TADMUS). The overall objective of the TADMUS program is to improve tactical decision making of anti-air warfare (AAW) crew members within the Aegis cruiser's combat information center (CIC) under conditions of stress and uncertainty. The unique aspect of this effort is that each presentation addresses decision making behavior, within a single domain, from a different perspective. The goal of each effort is to characterize some aspect of expert decision making performance within the AAW task environment, and to make recommendations for the resulting decision support system design based upon these characterizations. The result is a multi-faceted, human-centered approach to information organization and interface display design for a decision support system.”

Perrin, Bruce M., Barnett, Barbara J. and Walrath, Larry C. (1993): Decision Making Bias in Complex Task Environments. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 1117-1121.

“This presentation summarizes the results of an empirical study examining human judgment bias under conditions of uncertainty and time pressure in surface Anti-Air Warfare (AAW). A substantial body of research has demonstrated that humans apply a limited set of heuristics to simplify decision making in complex and ambiguous situations. Most of this research, however, has used college students making logical, but unfamiliar judgments. This study was designed to assess whether Naval personnel, trained and experienced in AAW operations, exhibit these biases when performing their normal duties. Specifically, we studied whether the judgments of Naval tactical action officers in a realistic task simulation exhibit characteristics of the biases of availability, representativeness, anchoring-contrast, and confirmation. Our prediction that experienced subjects would disregard lack of reliability in otherwise representative data was only partially supported by the study. On the other hand, each of our other predictions was strongly supported. Our subjects ignored baseline trends when other case-specific information was available (representativeness and availability). They were significantly influenced by the order they received evidence, showing a recency effect characteristic of contrast. Additionally, as is characteristic of confirmation bias, they recalled much more of the information that was consistent with their final hypothesis and evaluated it as more informative than the inconsistent data, regardless of which hypothesis they had adopted. Implications for Naval decision support systems information and display are discussed.”

Barnett, Barbara J. (1989): Information Processing Components and Knowledge Representations: An Individual Differences Approach to Modeling Pilot Judgment. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 878-882.

“The study described here represents another step in an ongoing program of research (cf. Wickens, Stokes, Barnett,&Davis, 1987; Wickens, Stokes, Barnett,&Hyman, 1988). Specifically, the present study contrasts high-time and low-time pilot judgment performance, using information processing components and knowledge representations in long term memory (LTM) as individual difference measures to predict performance. The objective was to determine which of these two classes of measures predicted pilot judgment performance for groups of varying levels of experience. Thirty pilots (15 high-time and 15 low-time) completed a cognitive abilities assessment battery. This battery was comprised of two components: domain-independent information processing measures, and measures of domain-specific knowledge representations. These pilots then flew a cross-country flight on MIDIS, a microcomputer-based decision flight simulator. Each pilot's performance was assessed on a number of in-flight decisions. No significant differences in absolute performance were observed between high-time and low-time pilots, however the pattern of ability measures that predicted low-time pilot performance was different from those that predicted high-time performance. Specifically, high-time pilot performance was better-predicted by measures of domain-specific knowledge representations. Differences in predictor patterns suggest qualitative differences in decision-making strategies used by the two cohorts.”
