$this->bbcode_second_pass_quote('galacticsurfer', 'I') read an interesting article about intelligence in old age over the weekend which stated that scientists have discovered that our brain makes new neurons contantly(neurogenesis) as we learn. They do not just cointantly die off until we get old with half the brain gone. So it is not true that we cannot "evolve" as individuals after birth. I bet we could increase intelligence in any particular specialty area as an individual and new neurons would grow.
Read your sources more carefully. I think you'll find that what changes in the brain are
neural connections not numbers of neurons. You can easily observe the "practice effect" that you are incorrectly interpreting as an increase in intelligence.
Do you know the game "minesweeper"? It's a simple game that came packaged with some versions of Windows. You have a board composed of squares, and hidden beneath some of the squares are bombs (or mines). The squares that don't have mines on them contain a number showing how many mines are to be found among the adjacent squares. Your job is to uncover all the squares that do not have any mines, while not clicking on a mine square and getting blown up (game over).
The game comes on three levels, and I suggest the middle "intermediate" level for this test. The simplest level is too pathetically easy to be of any use except for demonstrating the game to a newbie. Working out hardest "expert" level involves too many decisions for which logic will be insufficient to solve the puzzle of where the mines are (i.e., you need both luck and skill to finish).
On the intermediate level, you'll probably take more than three minutes to finish your first game. But keep playing. You'll get faster. A week of regular daily practice should halve your time (to something like a hundred seconds). Another week of practice should get you into one-minute game territory.
No, you're not getting "more intelligent." You're
making use of the intelligence you always had. At some point, you'll top out in your game - minimizing the time you average to finish. For me, it was about 50 seconds: for a while, I was hitting routinely between 45 sec and 60 sec games.
Once you've gotten as fast as you can be at playing Minesweeper, stop playing for two weeks. Then go back and start playing again. Notice how your time has shot back up to 120+ seconds?
