Allan Reiss and his fellow researchers have a good idea why your male counterpart can’t seem to put down his X-Box 360 controller. In a groundbreaking, imaging study, Stanford University School of Medicine scholars have found that part of the brain that generates rewarding feelings is more active in men than women while playing video games.
The differences between male and female brain-activity while playing video games may help us fully understand why males are actually much more likely to get addicted to Nintendo games than females. Over 100 million video games wer sold in 2005. According to a survey by Harris Interactive in 2007, younger males are at least 2 to 3 times more likely than females to feel addicted to playing video games!
While playing the computer game, 11 men and 11 women (a total of 22 young adults) were hooked up to an fMRI machine which allowed researchers to understand what was going on in each of the brains. Each of the participants played several 24-second games while hooked up to the fMRI machine. The fMRI machines were able to produce dynamic images showing activity in specific areas of the brain during the game playing.
While playing the games, participants were told to attempt to click on as many balls as possible. They were not told that they would gain or lose space (territory) on the screen depending on how successful they were with clicking. All participants learned quickly how to play the game and the purpose of it. All of the male and female participants wound up clicking on roughly the same number of balls. Though they were relatively even in ball clicks, the male participants gained a greater amount of territory than the women. This was due to the fact that men identified which balls – [the balls closest to the wall] – would help them acquire the most territory when clicked.
The females fully understood the concept of the game and they moved the wall in the right direction. The difference between the male and female territory at the end of the game was summed up by study leader Allan Reiss: “They (the females) appeared motivated to succeed at the game. The males were just a lot more motivated to succeed.”
After thoroughly analyzing the MRI imagery and data of the entire group of players (11 men and 11 women), the researchers learned that the participants’ brains showed activation in the mesocorticolimbic center – a region commonly associated with addiction and reward. The difference between the male and female brains was in the amount of activation in the mesocorticolimbic center. The brains of the 11 male young adults showed much greater activity. And, to top things off, researchers discovered that the amount of activity closely correlated with how much space (territory) they gained during the game. (This correlation didn’t happen to occur in the women participants). Three more key brain structures involved in our reward circuitry: the amygdala, the orbitofrontal cortex, and the nucleus accumbens – were also shown to influence each other in men much more than women. The better connected this circuitry, the better the males performed at the computer game!
