The Pros And Cons Of Situational Awareness

There are several measurements used today that measure situational awareness, each with its own uniqueness, pros, and cons. The first is the Situational Awareness Rating Technique (SART) which is a subjective measurement for SA developed by Taylor (1989). In SART, participants are asked to rate their own SA levels throughout the scenario, which allows to see how participants think they preform and to measure their perceived SA. However, when using subjective measurements, it is possible that the participants are unaware of information they do not know, which effects their SA ratings (Luft & Ingram, 1955). In addition, this study also assesses confidence levels which is a kind of subjective measurement for the objective SA measurement. Thus, in the current study we will use the Situation Awareness Global Assessment Technique (SAGAT) (Endsley, 2000) to measure participants SA levels and added confidence levels in the form of a 0 to 100% scale for each answer to test whether a relation between SA (accuracy) and confidence levels will emerge, and if so, will there be a difference in SA when participants are under or over confident. …show more content…
This measure combines an objective measure in the form of true/false probes and a subjective measure of 1-5 Likert scale confidence rating in the given answer. The computation is based on Single Detection Theory (SDT) which divides the answers in to four possible outcomes- Hit (knowing the answer is correct); Miss (thinking a right answer is wrong); False Alarm (thinking a wrong answer is correct); and Correct rejection (knowing a wrong answer is incorrect). This study will not use QUASA for several reasons. First, this questioner interprets results in terms of signal detection theory which is not completely appropriate for our form of
