Situation awareness is the perception of environmental elements with respect to time or space, the comprehension of their meaning, and the projection of their status after some variable has changed, such as time, or some other variable, such as a predetermined event. It is also a field of study concerned with perception of the environment critical to decision-makers in complex, dynamic areas from aviation, air traffic control, ship navigation, power plant operations, military command and control, and emergency services such as fire fighting and policing; to more ordinary but nevertheless complex tasks such as driving an automobile or riding a bicycle. Situation awareness (SA) involves being aware of what is happening in the vicinity, in order to understand how information, events, and one’s own actions will impact goals and objectives, both immediately and in the near future. One with an adept sense of situation awareness generally has a high degree of knowledge with respect to inputs and outputs of a system, i.e. an innate “feel” for situations, people, and events that play out due to variables the subject can control. Lacking or inadequate situation awareness has been identified as one of the primary factors in accidents attributed to human error. Thus, situation awareness is especially important in work domains where the information flow can be quite high and poor decisions may lead to serious consequences (e.g., piloting an airplane, functioning as a soldier, or treating critically ill or injured patients). Having complete, accurate and up-to-the-minute SA is essential where technological and situational complexity on the human decision-maker are a concern. Situation awareness has been recognized as a critical, yet often elusive, foundation for successful decision-making across a broad range of complex and dynamic systems, including aviation, air traffic control, ship navigation, health care, emergency response and military command and control operations, and offshore oil and nuclear power plant management. Situation awareness is often studied in the context of leadership and roles involving time-critical applications, however it is often referenced in other fields as well. For example, in the study of influence, situation awareness is found to be a critical component. This is further extended into the animal kingdom, where very often the alpha pair demonstrates superior situation awareness with respect to the well being of those within the animal pack.
