ABSTRACT
Naturalistic studies of problem-solving behavior have several specific missions in comparison with their counterparts carried out in simulated environments such as laboratories. As an end, they are to provide knowledge to designers on what strategies are likely to be adopted in the real world, what problems actually face practitioners, and what training and cognitive supports would be desirable (Bainbridge, 1983; Klein, 1989; Reason 1987). As a means, they are to provide laboratory investigators needed guidance to formulate experimental designs that cover the range of problems facing practitioners (Sheridan & Hennessy, 1984).
