Psychoanalytic Theory is when you us the Freuds or Lacans Theory's.

Freuds Theory was based on how people's egos effect on what they do and he says there are three types there is the Ego its self which does all the work for the Super ego and the super ego is the one which make the decisions on which is can and can't do. which brings me to talk about the ID which is the naughty ego for say like thats the ego that tries making you doing all the wrong decisions like robbing a bank or killing someone and the ego tries to stop it and the super ego make the decision saying its wrong.
