Your comment reminded me of how a lot of sales training / pick-up artist gaming revolves around neuro-linguistic programming.

Mirroring & matching, imitating the body language, tone, speed, diction of those you interact with, is an important facet of NLP and subsequently the art of persuasion - and as an aside, having preset rules to follow makes one feel as though they are playing a 'role' and acting, thereby increasing confidence as well.
