The most widely cited and accepted model of SA was developed by Dr. Mica Endsley, [25] which has been shown to be largely supported by research findings. [34] Lee, Cassano-Pinche, and Vicente found that Endsley's Model of SA received 50% more citations following its publication than any other paper in Human Factors compared to other papers in the 30 year period of their review.
Endsley has authored over 200 scientific articles and reports on situation awareness, [3] [4] decision making and automation and is recognized internationally for her pioneering work in the design, development and evaluation of systems to support human situation awareness and decision-making, based on her model of situation awareness. This ...
Endsley (2017) describes how high system reliability can lead users to disengage from monitoring systems, thereby increasing monitoring errors, decreasing situational awareness, and interfering with an operator's ability to re-assume control of the system in the event performance limitations have been exceeded.

[14] [31] [32] The most useful model in HPM is that of McCarley et al. (2002) known as the A-SA model (Attention/Situation Awareness). It incorporates two semi-independent components: a perception/attention module and a cognitive SA-updated module. [14] The P/A model of this A-SA model is based on the Theory of Visual Attention. [33] (Bundesen ...

The situational theory of publics theorizes that large groups of people can be divided into smaller groups based on the extent to which they are aware of a problem and the extent to which they do something about the problem. For example, some people may begin uninformed and uninvolved; communications to them may be intended to make them aware ...
The original conceptualization of objective self-awareness theory proposed by Duval and Wicklund suggested that a state of self-focused attention was an aversive state. That is, when people are drawn to focus on themselves like an external evaluator would, they are more likely to develop a negative mood state.
To date, systems that use context awareness to improve situational awareness can be characterised by: the context(s) that they collect from each user, and; the method by which they convey this information to other users; The most common context to obtain and share for the purposes of improving situational awareness is the user's location.
