psychological torture as 'creative correction'

My dh and I help clean a church for some extra $. When dusting the books in the library I find myself tempted by the books talked about here (that I've previously not had the desire to read). This week's 5 minute waste of my time was the bible study version of "Creative Correction" (by Lisa Whelchel, published by FOTF).

I only read a few of her 'creative' ideas, but I was immediately struck by how similar her suggestions are to psychological torture.

I went through prisoner of war training when I was in the military. It was in the early 90s (pre-Gulf War I), and much of the tactics used were those of Vietman era P.O.W.s. Some of the instructors had been P.O.W.s. During our training, they did not/were not able to physically torture us (there where things they did that caused minor pain to indicate, had it been a 'real' situation, when they would be dislocating our shoulders or hanging us up by our toes or the like). They did, however do a large amount of 'psychological' torture - all of which are mentioned in one form or another in the book:

deny food
deny use of electricity
hand cuff you to another person
blindfold
have stand in a corner with nose high on the wall - if nose drops below a certain line, add to the time, but don't explain why
control use of toilet facilities (even if just to 'make a point who's in charge')
mock you while they do these things to you

It's all 'crazing-making' stuff. It's supposed to be crazy-making stuff. As a prisoner of war, they are trying to completely break your will so you will do exactly what they want, when they want you to do it. We were adults, and knew what we were getting into. Prior to the exercise, we went through classroom training to learn how to resist the crazy-making. How to maintain your self-will when someone has complete control over you. How to fight so you don't actually go crazy. We knew the exercise would last no longer than 96 hours, and it was a miserable 4 days. But after it I was much better equipped had I ever become a P.O.W.

Admittedly, I was looking for the 'worst' examples in my 5 minutes (I had a job to do, afterall). But how can these things be justified as 'biblical'? Why would we want to treat our children like they are an 'enemy combatant'? Is striving for 'absolute control' of our children the least bit rational?
