Brain Research On Boys’ Preference For Video Games and Girls’ For Social Media

An anonymous reader quotes a report from The Wall Street Journal: Many parents of both boys and girls have witnessed striking differences in the way their kids use technology, with their sons generally gravitating to video games and their daughters often spending more of their screen time scrolling through social media. Emerging research indicates that brain differences between males and females help account for the split. According to a 2017 survey conducted by Pew Research Center, 41% of teenage boys said they spend too much time playing video games while only 11% of girls said they do. Marc Potenza, a psychiatry professor at Yale University, teamed up with researchers at universities in China to find out why. Using functional MRIs, which measure brain activity by detecting changes in blood flow, the team studied neural responses in young male and female gamers, particularly in the parts of the brain associated with reward processing and craving — a motivating factor in addiction. When the men and women were shown photos of people playing video games, those parts of the men’s brains showed higher levels of activation than those parts of the women’s brains. Brain regions that have been implicated in drug-addiction studies also were shown to be more highly activated in the men after gaming. The researchers said the results suggest men could be more biologically prone than women to developing internet gaming disorder. But girls and women aren’t free from problems when it comes to digital media. Data from Pew shows that, in general, women use social platforms such as Facebook, Instagram and Pinterest far more than men. Many girls and women are drawn to those photo-sharing sites because they like to form bonds and find similarities, says Rosanna Guadagno, a social psychologist at Stanford University. Even if women only use those sites more than men because that is where their friends are, many experts and parents say they have found that girls appear to have a greater fear of missing out, which compels them to keep up with what their friends are posting. Some recent studies show that girls feel the ill effects of too much social media use, such as depression and anxiety, more than boys do.
