Answer upon this article from __Joseph Riggio__ 
"Interesting article. I know this from the work we’ve done with soldiers. The fundamental design of our model was about using this same effect in reverse. The trainer would hold a positive state in place with the client for them so to speak, until that ability and sense of calm would replace the stress response.

Then when the client was matching the intentional state the trainer was holding, the trainer would model the specifics of how the client was in that calm state and develop a feedback loop. The key skills that the trainer had to bring online are the ability to access and sustain a state of calm in a more resourceful and resilient way than the client had to access stress, and the ability to use themselves simultaneously as an instrument to detect when the client’s state was changing in either direction. The modeling skills were also crucial, but useless if these other two critical skills weren’t in place first.

FWIW I personally learned a lot of this working with and training dogs. I had the unique experience of being involved in both learning and doing high level sophisticated dog training as I was simultaneously learning NLP. They’ve blended into a kind of singularity for me, and sometimes I feel more like I’m doing the work of the dog when I’m doing training with people than not."
