Preface. Cognitive engineering research at Riso from 1962-1979 (K.J. Vicente). Developing adaptability: a theory for the design of integrated-embedded training systems (S.W.J. Kozlowski et al.). Using pathfinder networks to analyze procedural knowledge in interactions with advanced technology (D.J. Gillan, N.J. Cooke). Some guidelines for conducting a cognitive task analysis (G. Klein, L. Militello). The application of human modeling technology to the design, evaluation and operation of complex systems (W. Zachary et al.). Training teams to take initiative: critical thinking in novel situations (M.S. Cohen, B.B. Thompson). Use of commercial, off-the-shelf, simulations for team research (C.A. Bowers, F. Jentsch). Understanding human performance in complex environments: research paradigms and emerging application areas (J.M. Hitt II, et al.).
