Name needed for psychological practice which uses objects that represent humans [dolls/pictures/etc.] during patient treatment What is the name of practice/method (if such exists) where psychologist uses a doll (or any other form of human-being representation) for patient to talk to?
I believe I have seen it in a movie or had read in a book (not exactly sure)
My guess would be that it could be used for patients that feel more comfortable talking to not alive objects that have human form or that portrait a human-being but that cannot respond (subconscious security for a patient that an object will not be judgmental towards patients issues or something like that..)
P.S. If such practice/method exists, which implications it has for the patient?
Example:

Movie: What about Bob?
forward to 1:40

EDIT:
What I found:

&quot;Puppets allow a child to displace feelings from the significant
persons with whom they were originally connected. In doing so, puppets
offer physical and psychological safety that, in turn, invites greater
self expression.&quot;

Thanks to caseyr547 for Play therapy term
It's often referred to as "doll therapy" or "play therapy" and applies to adults as much as it does to children. For example, this new product, the "Inner Critic Doll" enables adults to hold a physical manifestation of their inner critic and start a dialogue with it. It has a zipper mouth which can be zipped shut to physically silence this inner voice.

The doll enables adults to confront an otherwise "formless" part of their psyche and has proven to be highly effective.
It's used frequently by writers, artists, those suffering low self-esteem, etc., and I've even seen family members address each other on challenging topics via their inner critic doll, as it was easier than talking face-to-face.
