Quantitative Analysis of Situational Awareness (QUASA): Applying Signal Detection Theory to True/False Probes and Self-Ratings

摘要

This paper describes a technique for assessing the situational awareness of individuals such as warfighters participating in C2 experiments and exercises. Known as QUASA (quantitative analysis of situational awareness), the technique combines both objective queries (true/false probes) and subjective self-ratings of confidence for each probe response. The data so obtained are then analyzed and interpreted using the mathematical framework of Signal Detection Theory (SDT). The rationale behind the technique is described, followed by an example of its implementation and the results obtained. Further refinements of the technique based on recent research in experimental psychology are also considered.
