The schocking state of "science" is astonishing.
"The researchers tested this by having the two groups keep a cursor within a white square as it moved around a computer screen. At first, both groups performed equally. As the participants continued to practice, the gamers showed far better and quicker improvement in keeping the cursor in the square than non-gamers."
"They tested participants using a driving simulator. One group played action games for 5 to 10 hours, and the other played slower-paced games. The study found that the action players performed markedly better in subsequent simulator testing than the non-action players.
This literally proves nothing except that the gamers were more proficient with a mouse due to gaming, aka the more you use any tool, the better you get."
Results in the driving simulator do not tell how the person would perform IRL.
We already know that performing any activity alters the structure of the brain. If you read a lot, you will develop the area/areas responsible for reading and processing, they will increase in size. If you stop reading, the changes will revert. So no, those results are not permanent, nor semipermanent. The area will eventually shrink, it just takes time. It took years to develop, it will take years to shrink, not just the six months when the study was performed.
This is not science, this is tier 3 garbage pseudo science.
