ABSTRACT
The perceptual cycle model offers a more comprehensive description of how SA is developed and maintained than the three level model. SA requirements analysis is used to determine exactly what it is that actually makes up operator SA in the task or environment under analysis. Real-time probe techniques involve the administration of SA related queries during the active scenario. SA requirements analyses are conducted prior to an assessment of operator SA in order to identify what exactly comprises SA in the scenario or environment under analysis. The simulation should possess the ability to randomly blank all operator displays and 'window' displays, administer relevant SA queries and calculate participant SA scores. In order to remove potential correlation between SA ratings and task performance, no performance feedback should be given to the participant until after the self-rating stage is complete. The Situation Awareness Rating Scales technique is a subjective self-rating SA measurement technique of which a number exist.
