Even adults need attention, as we're social beings. Nothing wrong with that. But I wonder if because you have your therapy set up to reward your negative behavior with negative attention (T's stern voice and what have you), could both of you be unconsciously encouraging it? Could you experiment with this, perhaps have your "negative attention" be pre-emptive, like a negative warning not to do the negative things?

I think most human behavior is rational, if we understand what we're getting out of even what looks like suffering. My son once told me that he wanted to be sick more often because I pay such good attention to him. Yikes, so I tried to devote myself more to him when he wasn't sick, then he told me to back off. Haha. There's parenting in a nutshell.
