Proceed with caution: using verbal protocol analysis to measure situation awareness.

Verbal protocol analysis (VPA) is often used to elicit information about the cognitive processes of operators as it provides rich data and can be used in naturalistic settings. Recently VPA has been used to investigate the acquisition and maintenance of situation awareness (SA), and to make comparisons between groups despite a lack of research regarding the efficacy of using VPA for this purpose. This train simulator experiment investigated whether VPA can effectively measure SA.

The Low-Event Task Subjective Situation Awareness (LETSSA) technique: Development and evaluation of a new subjective measure of situation awareness.

Situation awareness (SA) is an important component of an individual's ability to function in a complex environment. As such, it is essential to have effective measures of an individual's SA. The most widely used subjective measure of SA is the Situation Awareness Rating Technique [SART].
