I believe that understanding relationships between units (objects, people, etc.) explains high intelligence, especially in autism, more than most average thinkers assume. People tend to fixate on the unit, and presume a relationship apropos between units. So, if we give core focus to memorizing the relationship then the unit, we may actually reinforce the neural pathways for both units and the abstraction between them without additional repetition.

My long-term memory is more efficient when I learn something from multiple angles. So, I don't look at basic algebra and just think, "X and Y are placeholders for numbers." I also think, "X can contain the value Y expressed as X=!Y." and "X can be a function of X expressed as X=X(X++)." and so on. This kind of ad-hoc modeling is about testing and defining the context of a relationship between units. And in that respect, I can say, anecdotally, that I consume information quickly and rarely have recall errors.
