ABSTRACT
This chapter examines the feasibility of using psycho-physiological measures to assess situation awareness (SA). The definition of SA used in this work is that commonly employed in the research community, namely the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future. Psycho-physiological data can be obtained continuously while the person focuses on the tasks at hand, thus removing the need for interference. The relationship between psycho-physiological measures with SA and other cognitive domains such as mental workload and fatigue have been studied for many years. The players, who were given specific tasks as part of the scenario, had to gain and maintain SA to achieve them. Central to the experiment was the ability to code the stimuli corresponding to the three SA levels.
