They have a propensity to need extreme structure in their lives and feel comfortable when someone they perceive as an "authority" stands over them and watches their behavior, rewarding them for good behavior and punishing them for bad.
I believe journey-on is correct about being institutionalized. But I think that is what causes the need for structure, not the other way around. I became very acclimated to structure and strict obedience as a born-in. I find that hard to break in myself now that I'm out. I have difficulty accomplishing or taking-on new tasks if there are not defined guidelines or persons to be accountable to for it. At the same time, I have come to have a sour taste for authority and the more I learn and become myself the more I am inclined to rebel against authority. The desire to be subservient was something the witnesses implanted in me, not a natural feeling that made be a witness.
