Playing video games has a strong correlation with the thickening of cortical matter of the left dorsolateral prefrontal cortex, or DLPFC, and the left frontal eye field, or FEF, as reported by David DiSalvo of Forbes. These two areas control decision making and hand-eye coordination.
Gamers have more opportunities to develop and hone their sensorimotor skills than those who don't play video games, according to Tech Times. While everyone possesses sensorimotor skills to some degree, constant practice allows them to become second nature. Once their skills develop, gamers can also learn new sensorimotor skills faster than others.
The link between improved hand-eye coordination and video gaming has real world applications, according to Beth Israel Deaconess Medical Center. A 2007 study revealed that surgeons who played video games out-performed their counterparts on laparoscopic surgery simulators, reporting that gamer surgeons committed up to 37 percent fewer errors. They were also 27 percent faster and scored 42 percent higher on other tests and drills.
A 2012 study by the University of Texas confirmed these findings by pitting high school students who moderately gamed against surgical residents who did not and measuring their hand-eye coordination, according to Beth Israel Deaconess Medical Center. Again, the high school students were able to outperform the medical residents. First-person shooting games such as Call of Duty are also correlated with a moderate increase in eyesight and contrast sensitivity.
