Researchers at Stanford University, using brain-imaging in a study of video game players, have concluded that "the part of the brain that generates feelings of reward is more stimulated in men than in women." The conclusion is therefore drawn that this neural affect explains why men are more likely to become addicted to video games. Speaking of the 22 test subjects, 11 male and 11 female, "The females 'got,' the game..." said Allan Reiss, who headed up the study. "They appeared motivated to succeed at the game. The males were just a lot more motivated to succeed." The game played involved gaining screen 'territory' by completing simple tasks and the researchers point out the the male of our species is definitely more territorial than the female, which could explain why the men were more driven to succeed. I think we're just amused by simple games and way too competitive for our own good. The CBC has the story.
