Utilization of Rough Sets Theory to Assess Physical andPsychological Fidelity within Scaled Worlds
Those who develop and apply scaled worlds in both research and practice are concerned about aspects of both physical and psychological fidelity. Physical fidelity centers on construction of an environment that is identical as possible to the work context. Psychological fidelity focuses on abstracting core components from the work environment and implementing those as an abstraction or as artifacts into the scaled world. Traditional statistical techniques for assessing both physical and psychological fidelity are often deficient. We describe rough sets theory, a technique that can be used to uncover relationships that exist in data between predictor variables and an outcome. After the introduction of the technique, it is applied to demonstrate how questions regarding the importance of team process, individual experience, and personality variables are related to performance within the C3 STARS (Command, Control, & Communications Simulation, Training and Research System) scaled world (Schiflett & Elliott, 2000).
