What is hyper vigilance? Is it a good thing or a bad thing? Should you have or should you avoid it? So many questions, so little time. Let’s jump in.
Hyper vigilance is a biological response to stress that causes your senses to go on high alert for danger. Your body goes on super alert status because it senses there is danger in the area. The hormones trigger biological changes that increase the acuity of your senses.
Stated another way, hyper vigilance can help your eyes see things that they might not have otherwise seen if you were not under stress. Likewise, hyper vigilance can help your ears hear things that they might not have otherwise heard if you were not under stress. And, for the sake of avoiding the annoyance of being repetitive, suffice it to say that all your senses are equally hyper aroused and on high alert. The stress of an emergency scene leads your brain to think there is danger in the area which makes your thinking (and in some cases your actions) primal.
Primal Goal #1: Survive!
The goal of the body and brain in a stress-induced, hyper aroused state is simple, Survive! What is out there that can kill you? Can you kill it? Can you outrun it? Those are the questions your brain is grappling with and your alert senses will help it make that determination. The human body is well-suited (based on genetic adaptation) to deal with these short-term stressors.
It was that kind of stress your cave-dwelling ancestors dealt with every day. Eat or be eaten. It was a pretty simple existence out there on the Serengeti. There were no worries about 401k plans, bad economies, looming mortgage payments or kids not doing well in school. The stresses of your daily lives are very different and in many ways – far more chronic and for more cumulative. On the upside, you don’t have to worry about a T-rex eating your kids when they leave the house.
So, we’ve established it. Hyper vigilance is a good thing! Well, don’t pop the Champagne corks yet. We’re not done.
The downside of hyper vigilance
Your brain is a wonderment of science, that is for certain. It can do things that no computer can duplicate. But it does have some limitations. One of those limitations is how much information it can take in, process, comprehend and recall at any one time. The question of just how much information that is intrigued the research community and in 1956 a cognitive psychologist at Princeton University named George Miller provided the shocking answer.
Seven! The average person can hold about seven pieces of unrelated information in their working (short term) memory, give or take two (for those slightly above and slightly below average performers). Miller’s studies have been robustly confirmed in numerous studies since. Coincidentally, it was the results of Miller’s research that led to the original seven-digit telephone numbering system in the United States.
This is where hyper vigilance can turn ugly in a hurry. Because your senses are hyper aroused, they are taking in more information about your surroundings. If your surroundings are simple and basic (like fighting a saber-toothed tiger in the jungle of the East Savannah (as your cave-dwelling ancestors did), then you didn’t have to worry about your brain getting overwhelmed with information.
But, put that brain on an emergency scene with dozens, maybe even hundreds of pieces of data coming at you and you are on the fast-track for overload. Some of the data is in writing, some audible, most is visual and nearly all of it is changing rapidly. It is easy to get overwhelmed in a hurry.
Drew Moldenhauer’s Advice
The solution to this problem was uncovered during the research conducted by cognitive psychologist Gary Klein, also known for his discovery of the Recognition-Primed Decision Making Process. Klein’s research involved trying to understand the decision making processes used by public safety commanders. One of the questions to be answered was: How do you make sense of it all? How do you process and comprehend so many clues and cues?
The answer was a stunner and entirely unexpected. The expert-level public safety commanders said they don’t try to process and comprehend all the information. In fact, there is just a small number of critical pieces of information essential for making a good decision. Commanders noted if they tried to comprehend it all, it would be impossible.
So, what should be on the short list for critical information to capture and process? Obviously, the answer would vary for each type of emergency you deal with.
The take-away lesson is: Stress causes hyper vigilance which increases your acuity. In a complex, fast-paced environment, that can accelerate cognitive overload. Less information, so long as it’s the right information, is your best ally. There are a couple more caveats about the information. The more complex the information, the more likely you are to be overwhelmed. The more detailed the information is, the more likely you are to be confused. And the more unfamiliar the information is, the more time you will need because you have to learn what the information means.
- Pick a type of emergency and detail the 7 (or less) critical pieces of information you think are essential to making a good decision.
- What tricks and secrets do you have for managing information in complex environments?
- Describe a situation where you realized, maybe even after the fact, that your senses were hyper vigilant and you heard or saw things that you might not have otherwise seen or heard.
