Each instruction from the hypnotist leads to either a “YES” or “NO” being emitted by the subject.
YES setting:
All right, I am cooperating, I understand what is being asked of me, I agree…
NO setting:
hm… I didn’t get it. I don’t agree with that. I’m not sure …
This inner attitude can manifest itself on a non-verbal level:
Arms crossed, micro-hesitation, gesture of refusal, incoherence…
It can manifest itself verbally:
Doubts are expressed, questions are asked or refusals are voiced.
Of course we need a YES from the test person as a prerequisite for success.
