Final Reflections: Situation Awareness Models and Measures

A response is provided to the many authors who commented on my initial paper for this special issue on situation awareness (SA) addressing remaining questions and observations on the Endsley 1995 model of SA. A discussion on historical perspectives on cognitive engineering and SA is included, along with future research needs for the construct. New models on sensemaking, distributed SA, and situated SA are also discussed, with remaining comments on their differences with the Endsley 1995 model of SA. Finally, a short discussion of SA measurement approaches is provided, addressing key issues raised in the commentaries.
