Seems to be a fear-fueled behavioral reaction to stimulus.
Take show horses. Some love it when the gooseneck backs up and the ramp unfolds. They know they're going to go somewhere new and fun and sparkly. Others balk and hide and gnaw at themselves because it's another day where they're going to get their mouths popped, their sides dug, and someone's going to point out every fault they have.
If VW is at least mostly fun, someone will enjoy it, but if they're going to get hauled around the floor, or maybe simply because THEY don't know how to do it well- it goes both ways- they're going to hate it.
To recondition a horse, one would start at the beginning and breeze through all of it up until the point of contention, then take it specifically apart and see just where the fissure starts, drop back below it, work up slowly through and slightly beyond to correct it, and keep things consistent.
But then, this is myself, speaking as someone who's never fallen and busted her ass during VW (only tango, partner-reversal, but my partner was a hottie, so falling on him wasn't *so* bad

LOL), and that perspective might change if/when I do.
