OK, so we talked about this in last week's workshop, here's the info plus some links for follow up study.
Remember, like I said on the day, the important thing is not just having this in your head but having a physical / psychological understanding too. Next time you do any kind of movements drills, especially, reference back and see the process at work. Step outside of the drill, if you will, and observe. Then put yourself back in.
Too much "martial arts" work is about mindless repetition, getting increasing numbers of reps under your belt, or whacking each other about for a bit. All well and good but look to understand underlying principles and your work will improve dramatically in the real world, not the martial arts world..
Particularly watch how Vladimir and especially Mikhail work at speed in relation to these concepts
OODA Loop
The O.O.D.A. Loop is a process that defines how we react to stimulus.
Observe, Orient, Decide and Act,
Colonel John Boyd coined the term O.O.D.A. Loop, in the 1950’s. An F-86 pilot and commander of a fighter group during the the Korean War. The planes flown were inferior to the MIGs of the enemy. At a disadvantage a competent pilot could still overcome that disadvantage by “attacking the mind” of his opponent. Boyd's observations led him to a greater understanding of Human reaction time and the coining of the term O.O.D.A. Loop. He trained his pilots based upon his observations of human reaction time and as a result his pilots had a 10 to 1 kill ratio over the superior Mig-15’s.
Human reaction time is defined as the time elapsing between the onset of a stimulus and the onset of a response to that stimulus.
First Observe. Remembner that although we process approximately 80% of the information we receive with our sense of sight, we can and do make observations with our other senses.
You might hear a gunshot Once you look and see the source of the gunfire you are now in the Orient stage of the process. In the Orient stage you are now focusing your attention on what you have just observed.
The next step is the Decide step in which you have to make a decision on what to do about what you have just observed. The last step is to Act upon that decision.
Simple Reaction Time is generally accepted to be around 220 milliseconds. In simple reaction time experiments, there is only one stimulus and one response.
Reaction to Auditory Stimulus is faster than reaction to Visual. Auditory Stimulus only takes 8-10 Milliseconds to reach the brain but a visual stimulus takes 20-40 milliseconds to reach the brain
Brake Light Theory”
You “Observe” the brake lights of the car in front of you come on. This is a “Known Stimulus” you already have a predetermined response. From the time we Observe the brake light (Onset of Stimulus) to the time we begin to remove our foot from the accelerator, (Onset of a reaction to Stimulus) less time has elapsed than if we were responding to an Unknown Stimulus
Flash Bang Theory.
Our reaction time is slower when we are responding to “Unknown Stimulus” such as sitting in living room and an object fliesy through the window. Just before it (a flashbang) goes off , reaction time is slowed by the fact that you have to respond to unknown stimulus - and this does not include what the effects of the flashbang going off will further do to disorient
There are other factors that can affect your O.O.D.A. Loop
In 1952 a researcher named Hick confirmed that by going from one response choice (Decision Step) to two, response time increased by 58%. This is widely known as “Hick’s Law”
Factors that affect your O.O.D.A. loop during the Orient step:
Denial is when you refuse to accept this is happening to you.
Emotional Filter is you wish that this were not happening.
Cultural factors can also come into play, as well as previous experiences. Fatigue is also a factor.
Researchers found that not only does increasing the number of responses affect your reaction time, but also by increasing the complexity of the tasks, induces stress that can adversely affect your reaction time.
Everyone's OODA. Loop is affected by the same factors as yours. This is one of the reasons why almost every drill incorporates moving. This has the effect of resetting your opponent’s OODA. Loop and giving you still another advantage.
"The key is to obscure your intentions and make them unpredictable to your opponent while you simultaneously clarify his intentions. That is, operate at a faster tempo to generate rapidly changing conditions that inhibit your opponent from adapting or reacting to those changes and that suppress or destroy his awareness. Thus, a hodgepodge of confusion and disorder occur to cause him to over- or under-react to conditions or activities that appear to be uncertain, ambiguous, or incomprehensible. "
