I figure, if I genuinly wonder if it was me or her it was her. You know when it is you, that is the definition of a conscious action, you knowingly act.
I believe it's important to recognize parroting and then recognizing what is actual conversation between the tulpa and I don't think you should be afraid of parroting but rather learning for yourself what's parroting and what's not
Doing some cursory googling, it looks like it's the "prism test", an exercise to allow your tulpa to express independence. You visualize a prism, then visualize a feather on top of it, then visualize the feather moving back and forth like a seesaw, and while you're concentrating on that, if your tulpa does something, you know you weren't puppeting because you were focusing on something else.
No idea how effective it is or whether many people still do it, but that seems to be how people used the term.

It's a visualisation technique supposedly used to mitigate 'parrotnoia', by forcing your effort and attention on visualising a physics simulation in proximity to your tulpa's head, thus 'proving' your tulpa's independence when they continue to move or talk. In theory. In practice, it just pisses people off, host and tulpa alike. There's a reason it's largely relegated to the bin, and not even our written history.
