In auditing having been given the suggestions by Hubbard about engrams, implanting et al people start to run them in session. In the TRs intense hypnotic states are achieved resulting in dissociation and the beginning of the construction of a cloned pseudo-identity. Scn'ists retreat into TRs when challenged, re-inducing the flat emotionless unresponsive state. Through Tone Scale drilling, people learn to pretend emotions. The downside is that they can lose spontaneity by doing so. They can lose the capacity for natural emotions.
With the CCHs, mimcry is used. The four basic forms of hypnosis or trance induction or heightening of suggestibility seem to be repetition, fixation, paradox (or confusion) and mimicry. On the objectives, people have dizzy dissociated feelings. Hubbard even said that on OpPro by Dup if the preclear says he feels as if he is "floating" to end off because s/he is "exterior". This spatial dissociation is a common fact know to all hypnotists (and Hubbard of course claimed great expertise as a hypnotist). Psychiatrists call it "depersonalization". Oddly enough, large doses of vitamin B-6 can also create this state. Don't try it, you'll end up in the funny farm.
Along side all this runs the loaded language. Scn had 1,000 pages of redefined and newly invented words (or neologisms if you want to get technical). This language redefines reality for the victim just as Korzybski said it would ("the map is not the territory - the word is not the thing itself). Margaret Singer quite rightly praises Orwell for his analysis of language in 1984 in her excellent Cults in Our Midst. Hubbard engaged greatly in doublethink. So words reverse in meaning (reasonable, for example) and the individual comes to think within the language - to map reality using Hubbard ideas. This is partly why Scn'ists don't recover unaided. They have been cognitively restructured.
Feel free to put this on the Net with my name on it but without my email address! There is much, much more to be said...
