I think it depends entirely on the situation.

There have been times I have acted out on purpose. I am the type of person that if you tell me "don't touch this... it's hot" I am going to touch it just to see how hot it really is. I almost always have to experience things first hand before they are truly engrained. I will test my boundaries, just to make sure they are truly there. Once I have determined that yes, that rule still does apply, I can go back to feeling safe and secure.

If we are talking about disobeying during edging specifically, I think this is also a very personal experience that is nearly impossible to compare. Say the task is to stop before going over the edge... on a scale of 1 to 10, where does this lie? 9? 9.5? 9.9? 9.9999999?? Different people might be going to different "edges".... each progressively more difficult to pull back from. And impossible to compare. At 9, you may still be in control.... at 9.9999999 your body starts to take over.

I know for myself, right before I cum I become almost incoherant. Rational thought is gone, and I will agree to nearly anything just to get what I want. There have been times I have broke down and sobbed when told "not yet." In that state, there is no "conscious" disobedience... there isn't any conscious anything.

So there is my addition to the confusion. You're welcome.
