I've never taken a SAT either. I'm guessing it has to do with the fact that people who use the quantity part of their brain are looking for numbers to plug into equations while people using the fact-driven part of their brain are trying to solve the problem.
I think it's the opposite. The people who accessed the left hemisphere area he mentioned were simply recalling the previously learned fact that 7-3=4, while those who accessed the right brain area that processes matters of quantity were the ones who were actually trying to figure out the difference between the two quantities, 7 and 3 from scratch. The latter is much more time and energy consuming.

It sounds to me like the moral is: the people who do better on the PSAT would be those who don't have to re-invent the wheel each time a wheel is called for. They just pull one off the shelf.
