This volume launches a series that will focus on providing chapters that advance our understanding of human performance in organizational systems as cognitive engineering principles are applied. Topics addressed in this volume include: a historical review of a cognitive engineering research at a national laboratory, an adaptive learning system approach to designing an integrated-embedded training system, application of PRONET, a method that provides a useful representation of sequences of behaviour in a human-machine interaction, application of CTA, a method to explain the mental processes involved in performing a task, application of human performance modelling technologies in system design and evaluation, a review of training critical thinking skills that individuals and teams require in changing environments, a review of commercial simulations for team research, and research paradigms for human performance research in complex systems.
