G'day Matt,
As far as controlling the actual Fight or Flight (FoF) (Aka Acute Stress response), there's not much you really can do. it is an automatic response and is controlled by the Sympathetic side of the Automatic Nervous System (ANS). Once it is triggered it is triggered it's kind of like trying to control a bullet that has been already been fired.
But there are things you can do that can influence the intensity and nature of the response as well as returning your system to a natural state quicker.
The first thing is to recognise that FoF is an Emotional response that is elicited most often by "E" situations for e.g. Emergency, Embarrassment, Exercise and Excitement. it is most often the emotional response to the emotion of fear. Emergency and Embarrassment produce fear, fear of dying, getting injured, pain, fear of humiliation, failure, loss of status, loss of identity and so on. With regard to exercise and excitement it is not so much fear the elicits the response ( and the response although physiologically similar or identical is psychologically different ) it has been suggested that exercise, for e.g., produces a FoF response because the exercise itself produces physiological (bodily) stress that is similar to that and associated with the actions of fight and flight, which is what FoF prepares the body to do. so just like smiling can produce a happy emotion, so can exercise. basically the body goes shit I must have missed something I better give this fellow a hand, enter FoF. this theory is supported by the notion of the "second wind" or "hitting ( and getting over) the wall" in running etc.
Also humans tend to turn to emotional motivation to continue performance, to push them selves that little further this could also explain the triggering of FoF for exercise and excitement.
....... wait a sec I'm going of track here lets get back to your question
Public speaking, presentations, sales pitching, and all of these things elicit the emotion of fear. You've probably heard that most people rate public speaking as more fearful the facing death (mind you I believe this is because most can't actualize facing death whilst speaking in front of a group is easily actualized. level of fear depends on the perceived degree of expectation and reality of the feared outcome, our own defence mechanisms often prevent us from acknowledging our own mortality ....... anyway back to topic)
We can do very little to control the FoF response once it is triggered, however we can reduce the intensity of the response by adjusting our perceived threat of the stimulus. this is what triggers the response, our perceived level of threat of the inducing stimulus. If we perceive a stimulus as a great threat then we experience a higher intensity FoF compared to a stimulus that is perceived as being only mildly threatening.
To reduce the intensity of FoF, what we need to do to is to regulate our emotion (fear) so that the threat is seen as less. Actually it is more accurate to say we need to regulate the induction of the emotion by the stimulus. ie to control the intensity and duration of FoF we need to change the emotion (or reduce it), to do that we need to change the perception of the stimulus.
there are a couple of ways to do this, and they apply to the regulation of most emotions especially those considered to be negative (fear, anger, sadness, guilt etc). there are 5 basic ways of doing this
-Situation selection
Here you basically avoid the fear (and thus response) inducing stimulus. not real helpful in the world of business through. you choose stimulus or situations that don't elicit the response, you may attend meetings but not voice an opinion, or you may find excuses to not attend or so on. As you can see this doesn't really do much for you if you have to attend and present at these meetings. personally this is a bit of a cop out method, It might be OK for those with intense phobias where the induced fear results in extreme/harmful stress, but then again those individuals wouldn't be in a position to have to attend these meetings anyway, they would have already used situation selection to find employment that does not require exposure to the stimulus..
-Situation modification
This is where you actively try to modify the situation/stimulus or alter it's emotional impact. Adrenal stress training in RBSD is one example of this, so is the treatment of phobias. Familiarization can lead to a reduced emotional response, the phrase "practice makes perfect" can be restated to "practice makes it easier." Familiarisation essentially provides reinforcement that the feared outcome is unlikely to occur. you could attend Toastmasters or some other public speaking group to help change the emotional impact of public speaking.
alternative you can change the stimulus itself, maybe you could run it in a more familiar location, in your domain so to speak. you can introduce other strategies such as providing a morning tea during the meeting, this will provide a more social atmosphere, thus changing the stimulus. You can change the format , location, time, atmosphere, the presentation type, rearrange the meeting room to make it less hierarchal, more open and so on. The idea is to not avoid the situation but change it in a way that allows a less powerful emotional impact.
-Attentional deployment
Here you distract your perception so that it does not produce an emotional response. concentrate on the job at hand rather then the possible thoughts of others. Thought stopping is an active stopping of the thoughts of that elicit fear, you simply stop thinking about the things that elicit the emotion. distract yourself with the info your providing. we can't think of two things at once so plan it so that you do not think of the emotion eliciting thoughts at all. this isn't the same as thinking about them naked (though if it works) it's more about guiding your attention towards the relevant thoughts instead of allowing them to drift. You deflect your attention away from potentially threatening stimuli.
-Cognitive change
This involves re-evaluating the situation/stimulus and thus changing the emotional response. Does it REALLY matter? is it really that scary? do they really care if I stuff up, or forget what I'm saying? are they really going to judge me or is it the idea they are judging, do you really care what they think?
One way to reduce the emotional impact is to use downward social comparison, instead of upward comparisons. in these meetings you are probably presenting your ideas to people who are above you in status or rank with in the organisation. these people may out rank you in the office but what about other aspects of life, do they out rank you in Martial Arts, are they better then you or just more experienced. remember that there are people lower then you are on the corporate ladder, the reason you are in front of the big wigs is because you are further up the ladder, and because you have something to offer. they may be higher rank but you are the leader of the meeting, in there they are lower ranked then you.
Reframe the situation, it is not a career ending meeting but an opportunity to show others what you have. Each meeting is but one of many that you will give. if you stuff up what is the worst that can happen, and how bad of a stuff up would it really have to be to make that come true.
Reduce the Importance of the meeting, it is not the last thing you will do on earth, remember they have asked you for the presentation because they think you can provide them with solutions ideas etc, not because they think you're going to fail.
-Response modulation
This is an after attempt to regulate the emotional impact, where you directly try to control or influence the emotional response. you can't stop a fight or flight and you can't change the intensity of it after it kicks off. but what you can to is attempt to influence the Para-sympathetic nervous system (the system that returns you to a normal state, among other roles).
Deep breathing, relaxation, wiggling the toes pacing etc anything that helps relive the sensation of the FoF response (the first two I mention are biggies). You can even turn to cigarettes, alcohol, and drugs but this would be considered a negative thing. What you want to do is convince your body that the threat is over, by consciously relaxing and attempting to restore your natural state. you do the things opposite to what happens in FoF i.e. instead of short shallow breaths you take long deep ones, use up the energy in your legs in a relaxed controlled manner, stretch to loosen the muscles and promote and re-establish full body blood circulation.
Obviously you can combine the above in any way. I've been specific to office meetings but you should be able to see how to transfer this to other emotional response eliciting stimuli.
Hope that helps.
noe tell the truth did you actually read it all.
