I cannot make any comment about the AVRT program and the voice question under discussion because I have not looked into that program model. I have been reading various posts that mention the addictive voice and it sounds similar to the Freudian concept of the ID, that part of the human psyche that is interested in pleasures, risks, selfish gratifications. Is that comparison valid? And is the rational voice and view point seem similar to an Ego fortified with knowledge, aversion to danger, etc. I just wondered if there was a basis in human development psychology of the AVRT model?
