Why get some people joy from physical activity while others like to stay on the couch?
Why have some kids problems with the Marshmallow test while others don't?
My guess is that i goes down to the internal reward system. If your brain rewards itself when you have successfully solved a puzzle, you are more likely to seek other puzzles - instead of going for a run like the one who gets a runners high.
I expect a part of that to be innate but also that brain plasticity allows for education to work on those reward systems by triggering one reward with another. When you get affection for problem solving, after a while problem solving will be its own reward, even without external reinforcement. And it may be important if you get rewarded for correct answers instead of fast answers.
and
Thermodynamics: we think whatever is easiest to think. Our brains require a lot of energy, however we are adapted to conserve energy rather than to use it recklessly thinking about all kinds of intensive topics. We might need it for running or for building up fat. Therefore after a certain amount of thought without generous reward for that thought our brains turn against thinking by means of: distractions, depressions, manias, sleepiness, anxieties and so on.
I agree that neuroscience and motivation science are strong influencers of "belief".
There is indeed a tension in the brain between conserving glucose, and using glucose to experience situations that get us into the FLOW state. (We've got chemicals in the brain whose job it is to IMPEDE the creation of long term memories, because creating long term memories is a glucose-intensive activity.)
And yes Heyo, INTRINSIC motivation is the strongest / best type of motivation on the motivation hierarchy.
In terms of the old nature vs nurture debate, I think nurture plays a HUGE role in how a person develops cognitively. When I was a kid, my Mom took me to the library every week, thanks Mom!! I've talked to a lot of people about this and I know I was extremely fortunate in this regard. At an early age I learned how much fun learning / reading / discovery could be.
We're on the religious forums, so of course I have to bring this up. While many religious people had the sort of library-enhanced good fortune that I had, it's also the case that MANY kids brought up in religious homes were indoctrinated with religion, and often this indoctrination suppresses exploration and creative thinking. There are a lot of people who have primarily been exposed to one book in their lives!!! Yikes!
You can guess where this rant is going: It's easier for the indoctrinated to believe than for those who were taught to explore.
