Dissertation/Thesis Abstract

Measuring situation awareness: Can the presentation of an online probe question change an operator's situation awareness?
by Bacon, L. Paige, M.S., California State University, Long Beach, 2011, 104; 1507621
Abstract (Summary)

Situation awareness (SA) is an operator's awareness of his or her environment and commonly referred to by air traffic controllers as "having the picture." Prior studies of SA measurement have examined the variety of techniques in terms of reliability, validity, diagnosticity, and usability. However, no previous research has investigated the intrusiveness of the online-probe technique (SPAM) to an operator's SA. Twelve student air traffic controllers served as participants. There were 3 question-event relationships administered prior to a scheduled flight plan deviation with two questions per scenario being one of the question-event relationships. The time to detect the flight plan deviation after the presentation of the question was collected. The results of the present experiment reveal that the type of question-event relationship preceding a scheduled flight plan deviation did not change the time it took participants to detect the flight plan deviation. Additional analyses, methodological implications, and future directions are discussed.
