What are the fundamental criteria that determine the hierarchy of saved information in the brain?
I've discovered that our languages reflect some of those factors. One of them can be sex identification - I've noticed this when I was reading The story of your life, I couldn't really imagine the character of the main hero without the knowledge of her sex.
Another criterium could be time. In many languages, an event cannot be expressed without the knowledge of the time it had taken place.
Do we know what is the fundamental hierarchy of creating memories (I accept a very broad answer :)?
