Title: Cognitive Modeling in the Aviation Domain
Abstract: In our laboratory at George Mason University, we have been developing computational cognitive models of piloting behaviour with the combined aims of (1) testing how well a model can capture the demands of piloting and reproduce crucial aspects of pilot performance, and (2) using the models to predict the impact of interface changes or new training that might improve pilot performance. I will discuss our work in these areas and our attempts to empirically test the predicted improvements with pilots. Models of individual pilots were built using the ACT-R cognitive architecture to simulate a pilot acting alone and in concert with another pilot. The single pilot model simulated human performance in flying a descent using automated flight controls. Results of the simulation were used to propose and evaluate interventions designed to improve pilot performance. The model of crew interaction used two independent cognitive models to simulate two crew members working together to complete a checklist. Selected model parameters were systematically varied to determine their impact on the models performance and these data were used to make recommendations about pilot training. I will discuss the nature of the information models can provide in the design process as well as how the process of modeling people in complex domains provides insight into the modeling process itself.
