Cheryl Olson, a researcher specializing in child studies and computer games, stated that “(Fink). Video games clearly create common ground that young people can use to make friends.” (Fink) However, there are other potential benefits as well. Shawn, a psychologist at the University of Wisconsin, says “video games change your brain.” Playing computer games changes the physical structure of the brain in the same way as navigating a map, playing the piano, or learning. Games cause rewarding rushes and a powerful concentration of neurotransmitters such as dopamine that strengthen the neural circuits that build the brain. Although computer games can help children make friends online, communicating with strangers could be difficult.
