When I think about positive and negative effects of media I immediately think about video games. Video games have a great controversy around the globe because many people argue that they are actually good while others say that they create negative effects on teens. One of the video games that brings negative effects to teens is Call of Duty, while Brain Age, another video game, brings positive effects to them.
“Call of Duty” is a violent video game because you use different kinds of weapons to
kill your opponents in war. Violent games like Call of Duty cause an increase in emotional arousal . When they start playing these kind of violent games they get very addicted to them and they can’t just stop playing them. You have to solve many challenges in war games but you have to solve them with violence. When I first played Call of Duty, I played it for like four hours straight and then I just started felt like I wanted to look for a gun and start shooting. What you actually learn in this war game or in any other video game that has guns is that you can solve everything with violence. Many studies also show that all kind of violent games, not only Call of Duty, produces increases tendencies in kids.
In a recent research study, adolescents played two different types of video games for 30 minutes. Teens that played the violent game (right) showed increased activity in the amygdala, which is involved in emotional arousal.

While there’s violent games that affect teens, there are also video games like Brain Age that might bring positive effects to them. Brain Age is a video game in which you can solve math problems, play a challenging game of rock, paper, scissors, and you can also test your memory skills. This kind of games help teens to build their brain and be smarter instead of leading you to get a weapon and start shooting with violent games. Research has been conducted around the world and they actually show that teens in schools show more improvements in concentration and behavior after playing Brain Age. Brain Age exercises your mind by just playing it and is a good way to entertain yourself using media that would not harm any of you.
Many teens would chose to play Call of Duty instead of Brain Age because one has action and the other is about school material. But there is one difference between this two games: one is that Call of Duty brings negative effects to teens by leading them to a decrease in self-control and Brain Age brings positive effects to them by building their brains.
