Can you go from being less perceiving to more judging? Perhaps, as I've noticed myself change after cognitive therapy.

Before cognitive therapy, I would read my emotions literally. If you asked me, "Are you scared?" I'd simply inspect my emotional state, find fear, and reply, "Yes, I'm scared." But through the ingrained disputation practices of cognitive therapy, I now vet these emotions. If you asked me today, "Are you scared?" I'd first acknowledge my emotions, then I'd think about whether the offending object was something to be scared of. If the answer came back "no," then my internal dialog would change, and I would say, "No, I am not really scared of this. I may be spooked or rattled, but only so."
