the difference here: this to you from a textbook....

"modern psychoanalytic theory has moved away from Freud's original conception of psychic energy. In current thinking, the assumption is that it is the mind's capacity for processing information, rather than it's energy."

Can someone please explain to me the difference? I don't see one lol. If you don't have the capacity to process a peice of information, how will that not take energy to try to do so?

Yes this is may seem very irrelevent, but dang it Freud was right.
