Content in This Guide. The future of any society depends on its ability to foster the healthy development of the next generation. Extensive research on the biology of stress now shows that healthy development can be derailed by excessive or prolonged activation of stress response systems in the body and brain. Learning how to cope with adversity is an important part of healthy child development. When we are threatened, our bodies prepare us to respond by increasing our heart rate, blood pressure, and stress hormones, such as cortisol.
The result is the development of healthy stress response systems.

However, if the stress response is extreme and long-lasting, and buffering relationships are unavailable to the child, the result can be damaged, weakened systems and brain architecture , with lifelong repercussions. The more adverse experiences in childhood, the greater the likelihood of developmental delays and later health problems, including heart disease, diabetes, substance abuse, and depression.
They get an idea that sounds good and they simply stop thinking. Within the context of social networks, many, including Metcalfe himself, have proposed.

However, although evidence exists to suggest a positive relation between SA and performance, this connection is probabilistic and not always direct and unequivocal Endsley, b. In other words, good SA does not always lead to good performance and poor SA does not always lead to poor performance Endsley, Thus, performance measures should be used in conjunction with others measures of SA that directly assess this construct.
Behavioral measures also "infer" SA from the actions that individuals choose to take, based on the assumption that good actions will follow from good SA and vice versa. Behavioral measures rely primarily on observer ratings, and are, thus, somewhat subjective in nature. This approach removes some of the subjectivity associated with making judgments about an individual's internal state of knowledge by allowing them to make judgments about SA indicators that are more readily observable.
Process indices examine how individuals process information in their environment, such as by analyzing communication patterns between team members or using eye tracking devices. Thus, since SA may be distributed via communication, computational linguistics and machine learning techniques can be combined with natural language analytical techniques e. Psycho-physiological measures also serve as process indices of operator SA by providing an assessment of the relationship between human performance and a corrected change in the operator's physiology e.
In other words, cognitive activity is associated with changes in the operator's physiological states. For example, the operator's overall functional state as assessed using psycho-physiological measures, such as electroencephalographic EEG data, eyeblinks, and cardiac activity may provide an indication as to whether the operator is sleep fatigued at one end of the continuum, or mentally overloaded at the other end Wilson, Other psycho-physiological measures, such as event related potentials ERP , event related desynchronization ERD , transient heart rate HR , and electrodermal activity EDA , may be useful for evaluating an operator's perception of critical environmental cues, that is, to determine if the operator has detected and perceived a task-relevant stimulus Wilson, In addition, it is also possible to use psycho-physiological measures to monitor operators' environmental expectancies, that is, their physiological responses to upcoming events, as a measure of their current level of SA Wilson, The multivariate nature of SA significantly complicates its quantification and measurement, as it is conceivable that a metric may only tap into one aspect of the operator's SA.
Further, studies have shown that different types of SA measures do not always correlate strongly with each other cf. Accordingly, rather than rely on a single approach or metric, valid and reliable measurement of SA should utilize a battery of distinct yet related measures that complement each other e. Such a multi-faced approach to SA measurement capitalizes on the strengths of each measure while minimizing the limitations inherent in each. She has trained EF fighter pilots and Canadair firefighters.
This situation awareness training aims to avoid losing SA and provide pilots cognitive resources to always operate below the maximum workload that they can withstand.

This provides not only a lower probability of incidents and accidents by human factors, but the hours of operation are at their optimum efficiency, extending the operating life of systems and operators. In first aid medical training provided by the American Red Cross , the need to be aware of the situation within the area of influence as one approaches an individual requiring medical assistance is the first aspect for responders to consider  Examining the area and being aware of potential hazards, including the hazards which may have caused the injuries being treated, is an effort to ensure that responders do not themselves get injured and require treatment as well.
Situation awareness for first responders in medical situations also includes evaluating and understanding what happened  to avoid injury of responders and also to provide information to other rescue agencies which may need to know what the situation is via radio prior to their arrival on the scene. In a medical context, situation awareness is applied to avoid further injury to already-injured individuals, to avoid injury to medical responders, and to inform other potential responders of hazardous conditions prior to their arrival.
In transport safety, a very important aspect is situational awareness. A loss in situational awareness has led to many plane crashes and numerous train disasters, including the Philadelphia train derailment as an example. Within the search and rescue context, situational awareness is applied primarily to avoid injury to search crews however being aware of the environment, the lay of the land, and the many other factors of influence within one's surroundings assists in the location of injured or missing individuals . In the United States Forest Service the use of chainsaws and crosscut saws requires training and certification.
Situational awareness in the forest context also includes evaluating the environment and the potential safety hazards within a saw crew's area of influence. As a sawyer approaches a task, the ground, wind, cloud cover, hillsides, and many other factors are examined and are considered proactively as part of trained sawyers' ingrained training. Dead or diseased trees within the reach of saw team crews are evaluated, the strength and direction of the wind is evaluated. The lay of tree sections to be bucked or the lean of a tree to be felled is evaluated within the context of being aware of where the tree will fall or move to when cut, where the other members of the saw team are located, how they are moving, whether hikers are within the area of influence, whether hikers are moving or are stationary.
Law enforcement training includes being situationally aware of what is going on around the police officer before, during, and after interactions with the general public  while also being fully aware of what is happening around the officer in areas not currently the focus of an officer's immediate task. In the law enforcement context, situation awareness involves keeping eyes and ears open and evaluating what is happening on the way to a specific task, remaining fully aware of one's surroundings during the commission of a task, and retaining one's awareness when exiting a specific task.
Situational awareness in a law enforcement setting seeks to ensure that a police officer does not become focused and engrossed on a specific task or problem to the exclusion of being aware of approaching potential hazards or to the exclusion of being aware of other tasks of higher priority. In cybersecurity, consider situational awareness, for threat operations, is being able to perceive threat activity and vulnerability in context so that the following can be actively defended: data, information, knowledge, and wisdom from compromise.
Empirical evidence about recovery and mental health
Situational awareness is achieved by developing and using solutions that often consume data and information from many different sources. Technology and algorithms are then used to apply knowledge and wisdom in order to discern patterns of behavior that point to possible, probable, and real threats. Situational awareness for cybersecurity threat operations teams appears in the form of a condensed, enriched, often graphical, prioritized, and easily searchable view of systems that are inside or related to security areas of responsibility such as corporate networks or those used for national security interests.
Different studies have analyzed the perception of security and privacy in the context of eHealth,  network security,  or using collaborative approaches to improve the awareness of users. As the capabilities of technological agents increases, it becomes more important that their actions and underlying rational becomes transparent. In the military realm, agent transparency has been investigated as unmanned vehicles are being employed more frequently.
In , researchers at the U. Army Research Laboratory designed three levels of situational awareness transparency based on Endsley's theory of prediction, comprehension, and projection. The greater the level of situational awareness, they claimed, the more information the agent conveys to the user. A publication from the U. Army Research Laboratory evaluated how varying transparency levels in the SAT affects the operator workload and a human's understanding of when it is necessary to intervene in the agent's decision making.
The researchers refer to this supervisory judgement as calibration. Scientists provided three standard levels of SAT in addition to a fourth level which included the agent's level of uncertainty in its decision in unmanned vehicles. The stated goal of this research was to determine how modifying levels of SAT affected user performance, situation awareness, and confidence in the agent.
The scientists stated that their experimental results support that increased agent transparency improved the performance of the operator and human confidence on the agent without a significant effect on the workload.
When the agent communicated levels of uncertainty in the task assigned, those involved in the experimentation displayed more trust in the agent. The ASM research was conducted by providing a simulation game in which the participant had to complete a training course with an ASM, a ground robot that communicates with infantry. The participants had to multitask, evaluating potential threats while monitoring the ASM's communications on the interface. According to that research, experimental results demonstrated that the greatest confidence calibration occurred when the agent communicated information of all three levels of SAT.
Army Research Laboratory developed transparency visualization concepts in which the agents can communicate their plans, motivations, and projected outcomes through icons. The agent has been reported to be able to relate it's resource usage, reasoning, predicted resource loss, progress towards task completion, etc. Crowdsourcing , made possible by the rise of social media and ubiquitous mobile access has a potential for considerably enhancing situation awareness of both, responsible authorities and citizens themselves for emergency and crisis situations by employing or using "citizens as sensors".
Since the National Information Sharing Consortium NISC has worked to provide "the right information to the right people at the right time" by use of common terminology among the emergency management community and first-responders with a mission of standardizing the structured geo-spatial data to be shared online over a variety of platforms. The result is to create a Common Operating Picture COP that generates accurate and timely information displayed visually, both at the strategic level for decision makers and at the tactical level for people on site.
The NISC promotes the sharing of code, data widgets, and training in order to increase the quality of the situational awareness. There are two training scenarios designed to increase the situational awareness skills of military professionals, and first responders in police and emergency services. The first, Kim's Game , has a more common place in the Marine Corps sniper school and police academies.
The name is derived from the novel Kim which references the game to a spy school lesson. The game involves a tray with various items such as spoons, pencils, bullets, and any other items the soldiers would be familiar with. The participants are given one minute to view all of these items before they are covered up with a blanket.
The participants would then individually list the items that they saw, the one with the most correct answers would win the game. The second method is a more practical military application of Kim's Game. It starts with a field area jungle, bush or forest of about five meters wide to 10 meters deep where various items, some camouflaged and some not, to be located in the area on the ground and in the trees at eyesight level.
Again, these items would be ones that are familiar to the soldiers undergoing the exercise. The participants would be given 10 minutes to view the area from one place and take a mental note of the items they saw. Once their 10 minutes is up, the soldier would then be required to do a repetition of certain exercises such as burpees , designed to simulate the stress of a physically demanding environment.
Once the participant completes the exercise, they would list the items they saw. The points would be tallied in the end to find the winner. From Wikipedia, the free encyclopedia.
