Violent video games have been shown to influence violent behavior in teenagers in real life.

This is because violent acts are continually repeated throughout the video game. This method of repetition has long been considered an effective teaching method in reinforcing learning patterns.

In a murder case on August 2008, an eighteen-year old Thai student murdered a 54-year old taxi driver while trying to recreate a scene from the Grand Theft Auto computer game. Polwat Chino, who was said to be an obsessive player of the controversial game, stabbed the taxi driver ten times. 'He said he wanted to find out if it was as easy in real life to rob a taxi as it was in the game,' chief police investigator Veeravit Pipattanasak said.

This clearly shows that violent video games can in fact cause teenagers to perform extremely violent and aggressive acts in real life.

I agree that violent computer games are responsible for aggressive behaviour in teenagers.

A report on April 23, 2000, from Washington states that, playing violent video games like Doom, Wolfenstein 3D or Mortal Kombat can increase a person's aggressive thoughts, feelings and behavior both in laboratory settings and in actual life, according to two studies appearing in the April issue of the American Psychological Association's (APA) Journal of Personality and Social Psychology. Furthermore, violent video games may be more harmful than violent television and movies because they are interactive, very engrossing and require the player to identify with the aggressor, say the researchers.

"One study reveals that young men who are habitually aggressive may be especially vulnerable to the aggression-enhancing effects of repeated exposure to violent games," said psychologists Craig A. Anderson, Ph.D., and Karen E. Dill, Ph.D. "The other study reveals that even a brief exposure to violent video games can temporarily increase aggressive behavior in all types of participants."The first study involved 227 college students who completed a measure of trait aggressiveness and reported their actual aggressive behaviors (delinquency) in the recent past. They also reported their video game playing habits. "We found that students who reported playing more violent video games in junior and high school engaged in more aggressive behavior," said lead author Anderson, of Iowa State University. "We also found that amount of time spent playing video games in the past was associated with lower academic grades in college."

In the second study, 210 college students played either a violent (Wolfenstein 3D) or nonviolent video game (Myst). A short time later, the students who played the violent video game punished an opponent (received a noise blast with varying intensity) for a longer period of time than did students who had played the nonviolent video game.

"Violent video games provide a forum for learning and practicing aggressive solutions to conflict situations," said Dr. Anderson. "In the short run, playing a violent video game appears to affect aggression by priming aggressive thoughts. Longer-term effects are likely to be longer lasting as well, as the player learns and practices new aggression-related scripts that can become more and more accessible for use when real-life conflict situations arise."

"One major concern is the active nature of the learning environment of the video game," say the authors. "This medium is potentially more dangerous than exposure to violent television and movies, which are known to have substantial effects on aggression and violence."

I believe that violent computer games are responsible for aggressive behaviour in teenagers.

Recent acts of extreme violence involving teens and associated links to violent video games have led to an increased interest in video game violence. Research suggests that violent video games influence aggressive behavior, aggressive affect, aggressive cognition, and physiological arousal. Anderson and Bushman [Annu. Rev. Psychol. 53 (2002) 27.] have posited a General Aggression Model (GAM) to explain the mechanism behind the link between violent video games and aggressive behavior.

Another study conducted by Gentile, Lynch, Linder & Walsh (2004, p.6) "adolescent girls played video games for an average of 5 hours a week, whereas boys averaged 13 hours a week". The authors also stated that teens who play violent video games for extended periods of time: Tend to be more aggressive AND may engage in fights with their peers. Since violent acts are continually repeated throughout the video game teenagers would feel that it would be normal to behave as such to do it in real life as well. Hence, from these statistics, i conclude that violent computer games are responsible for aggressive behaviour in teenagers.

Yes, I agree that violent video/computer games are responsible for agressive behavior in children and teenagers. Teenagers and children who play violent video/computer games may see  those violent actions as normal actions. This is because, when they play violent video games, they may think that it is "Normal" for them to act that way as the characters they play can act like that, too ignorant to the real world.

Eventually it becomes "normal" in their thinking, as in gangs, and that situation is often brought up in court when young people commit crimes of violence similarly to the violent games that they play. This is because, they can be inspired by it, influenced by it due to the repetition of violent actions in violent video/computer games. They may want to try to do them themselves, as in in real life and not just in the computer games world.

For example, Gentile & Anderson (2003) state that playing video games may increase aggressive behavior because violent acts are continually repeated throughout the video game. This method of repetition has long been considered an effective teaching method in reinforcing learning patterns.

Thus, violent video/computer games are responsible for aggressive behaviour in children and teenagers as they can be affected by it in some ways. 

i agree that violent video games are responsible for aggressive behaviour in teenagers. firstly, i would like to make it clear that my stand on responsible is that it a sort of influence that makes the teenagers have violent thoughts.

Video games are excellent teaching tools because they reward players for engaging in certain types of behavior," study author Dr. Bruce Bartholow, associate professor of psychology at the University of Missouri, said in a written statement. "Unfortunately, in many popular video games, the behavior is violence."

For the study - published in the Journal of Experimental Social Psychology - researchers at the university had 70 young adults play either a violent or nonviolent video game for 25 minutes. After the game, the subjects looked at neutral pictures - like a man on a bike - or violent pictures - like a man with a gun - as the researchers measured their brain wave activity. It turned out that when shown a violent image, those who had played a violent game showed a smaller brain response than those who had played a tamer game. In other words, the violent games desensitized players to violent imagery - and subsequent testing showed that gamers who played violent games like "Killzone" and "Grand Theft Auto" behaved more aggressively against their gaming opponents.

maybe only one or two exposures to these kind of video games may not exactly cause a teenager to become a mass murderer, or else we would be having massacre almost everywhere. however, long term exposure may make long term influences on a teenager's mind that steers them to violent ways of dealing with problems

A new study conducted by Craig Anderson (PhD in Psychology), which analyzes 130 research reports on more than 130,000 subjects worldwide, proves conclusively that exposure to violent video games makes more aggressive, less caring kids, regardless of their age,sex or culture.

Exposure to violent video games is a casual risk factor for increased aggressive thoughts and behaviour and decreased empathy and prosocial behaviour in youths.Computer games have a negative impact on the development of children, especially contributing to aggressive and anti-social behaviour. Playing computer games has a greater negative effect because it involves interactivity which impacts on learning processes of the child.

The impact of computer games are especially influential since the games are highly engaging, children are rewarded by violent behaviour and they repeat this behaviour over and over as they play. Psychologists know that these three methods (active involvement, rewarding and repeating) improve learning. This is linked to a psychological term called "social learning" where a child learns by watching or imitating others, and its a process where a child's behaviour is negatively influenced by the aggressive, violent nature of computer games.

I agree that violent computer games are responsible for aggressive behaviour in teenagers.

I agree as violent video games have this system of risk and reward, let’s say if you are caught in a room in a game and u need to get out, the risk is if u didn’t manage to get out its game over and the reward is that you are able to kill and in the end able to get out of that room and continue to play. When these rewards are received immediately it will create an uncontrollable compulsion to repeat such a behaviour after which the game would have a similar scene which would promote violence, this caused a repetitive behaviour in violent video games. Once a person gets addicted to such games, it will slowly stimulate violence and thus enhancing the learning of violent behaviour. In a study, 210 college students were allowed to play Wolfenstein 3D, an extremely violent game, or Myst, a nonviolent game. After a short time, it was found that the students who played the violent game punished an opponent for a longer period of time compared to the students who played the non-violent game. Dr. Anderson concluded by saying, "Violent video games provide a forum for learning and practicing aggressive solutions to conflict situations. It the short run, playing a violent video game appears to affect aggression by priming aggressive thoughts." Despite the fact that this study was for a short term effect, longer term effects are likely to be possible as the player learns and practices new aggression-related scripts that can become more and more accessible for the real-life conflict that may arise.

On April 20, 1999, Eric Harris and Dylan Klebold launched an assault on Columbine High School in Littleton, Colorado, murdering 13 and wounding 23 before turning the guns on themselves. Although nothing is for certain as to why these boys did what they did, we do know that Harris and Klebold both enjoyed playing the bloody, shoot-'em-up video game Doom, a game licensed by the U.S. military to train soldiers to effectively kill. The Simon Wiesenthal Center, which tracks Internet hate groups, found in its archives a copy of Harris' web site with a version of Doom. He had customized it so that there were two shooters, each with extra weapons and unlimited ammunition, and the other people in the game could not fight back. For a class project, Harris and Klebold made a videotape that was similar to their customized version of Doom. In the video, Harris and Klebold were dressed in trench coats, carried guns, and killed school athletes. They acted out their videotaped performance in real life less than a year later. This shows that after playing violent video games that is a chance of yourself getting lost between the dream world and reality, making people unable to think straight and will promote violent actions.

Thus i agree that violent video games is responsible for aggressive behaviour behaviour in teenagers

I agree that violent computer games are responsible for aggressive behavior in teenagers.

According the American Psychological Association, violent video games can increase children's aggression. Dr. Phil McGraw points out that violent video games don't teach kids moral consequences. For example, if you shoot somebody in a game, you don't get sent to jail or penalized in some way. In fact, you get extra points! Teenagers who play these games tend to use more aggressive or foul language. Also, they have less ability to control their anger and they tend to inappropriately resolve anxiety by externalizing it. So when they have anxiety, they tend to externalize it.

Furthermore, the American Psychological Association says playing violent games correlates to teens being less caring and helpful toward their peers. These effects happen just as much for non-aggressive teens as they do for teens who already have aggressive tendencies. Teenagers spend a great deal of time with violent video games at exactly the ages that they should be learning healthy ways to relate to other people and to resolve conflicts peacefully. According to the National Institute on Media and the Family, teenage brains are in the midst of growth spurts, making teens very impressionable. Just when teens are wiring the circuits for self-control, responsibility and relationships that they will carry with them into adulthood, violent games activate their anger center while dampening the brain's "conscience."

I agree that violent computer games are responsible for aggressive behavior in teenagers.

For some teens, games are “everything.” That’s why there’s also growing concerns among parents about video games that range from: making kids more aggressive, developing sedentary lifestyles, squelching cognitive development or academic potential. After all, it’s very easy for teens to fall into the habit of spending too much time in front of those controllers.

Previous research has shown a connection between violent media and aggression, as well as violence and desensitization. But this study looks at how teenagers' brains specifically respond to violent media, said Jordan Grafman, senior investigator at the National Institute of Neurological Disorders and Stroke. Participants in the study were 22 boys ages 14 to 17. Each participant watched clips of violent scenes from 60 different videos, which included movies such as "World's Wildest Street Fights Vol. 1 and 2," Grafman said, and rated the aggression of the scenes. Researchers could observe their brain function because each boy watched these scenes while in a functional magnetic resonance imaging (fMRI) scanner.

These brain images showed that more aggressive violence was associated with desensitization in the lateral orbitofrontal cortex of the brain, which scientists believe has to do with emotions and emotional responses to events. They measured this by looking at the deoxygenation of blood in this area of the brain and how it changes over time.

Participants also wore electrodes on the fingers of one hand to measure the electrical conductance of the skin, which indicates emotion. This was used to look at how desensitized the boys were to different videos, depending on the level of violence. This electrical conductance test showed that the boys appeared to be more desensitized by the mildly and moderately violent videos than the ones with a low-level of violence. Boys who had the greatest level of exposure to violent media routinely showed the greatest desensitization in this study.

I agree that violent computer games are indeed responsible for the aggressive behaviour in teenagers.

After a study done by the University of Missouri (MU), they have proven that violent computer games are indeed responsible for aggressive behaviour in teenagers. The study provides one explanation for why this occurs: the brains of violent video game players become less responsive to violence, and this diminished brain response predicts an increase in aggression. During the study, 70 teenager participants were randomly assigned to play either a nonviolent or a violent video game for 25 minutes. Immediately afterwards, the researchers measured brain responses as participants viewed a series of neutral photos, such as a man on a bike, and violent photos, such as a man holding a gun in another man's mouth. Finally, participants competed against an opponent in a task that allowed them to give their opponent a controllable blast of loud noise. The level of noise blast the participants set for their opponent was the measure of aggression. The researchers found that participants who played one of several popular violent games, such as "Call of Duty," "Hitman," "Killzone" and "Grand Theft Auto," set louder noise blasts for their opponents during the competitive task -- that is, they were more aggressive -- than participants who played a nonviolent game. In addition, for participants that had not played many violent video games before completing the study, playing a violent game in the lab caused a reduced brain response to the photos of violence -- an indicator of desensitization. Moreover, this reduced brain response predicted participants' aggression levels: the smaller the brain response to violent photos, the more aggressive participants were. Participants who had already spent a lot of time playing violent video games before the study showed small brain response to the violent photos, regardless of which type of game they played in the lab. Bruce Bartholow, associate professor of psychology in the MU College of Arts and Science, said "More than any other media, these video games encourage active participation in violence," "From a psychological perspective, video games are excellent teaching tools because they reward players for engaging in certain types of behavior. Unfortunately, in many popular video games, the behavior is violence."

From the above evidence, you can tell that violent computer games are responsible for aggressive behaviour in teenagers as those who played violent games set louder noise blast for their opponent in the competitive round compared to those who played non-violent games. Also, participants who had not played many violent video games before, had a reduced brain response to the photos of violence as the smaller the brain response, the more violent participants were.

Therefore, violent computer games are responsible for aggressive behaviour in teenagers.

I agree that violent computer games are responsible for aggressive behavior in teenagers.

Scientists have known for years that playing violent video games causes players to become more aggressive. The findings of a new University of Missouri (MU) study provide one explanation for why this occurs: the brains of violent video game players become less responsive to violence, and this diminished brain response predicts an increase in aggression.

"Many researchers have believed that becoming desensitized to violence leads to increased human aggression. Until our study, however, this causal association had never been demonstrated experimentally," said Bruce Bartholow, associate professor of psychology in the MU College of Arts and Science

During the study, 70 young adult participants were randomly assigned to play either a nonviolent or a violent video game for 25 minutes. Immediately after-wards, the researchers measured brain responses as participants viewed a series of neutral photos, such as a man on a bike, and violent photos, such as a man holding a gun in another man's mouth. Finally, participants competed against an opponent in a task that allowed them to give their opponent a controllable blast of loud noise. The level of noise blast the participants set for their opponent was the measure of aggression.

Playing a violent video game can increase aggression, and when a player keeps thinking about the game, the potential for aggression can last for as long as 24 hours, according to a study in the current Social Psychological and Personality Science (published by SAGE).

Therefore, with these studies and research, i agree that violent computer games are responsible for aggressive behavior in teenagers.

I agree with the statement.

First of all, I would like to explain the meaning of the statement,

‘Violent video/computer games are responsible for aggressive behavior in children and teenagers.’

I would like to define it that not ALL the teenagers in the world who are violent are to blame violent video/computer games for their aggression, but rather if those teenagers are exposed to such games, then violent video/computer games ARE responsible for their aggressive behaviours.

Based on the studies done by Craig Anderson, a distinguished professor of psychology at Iowa State University and the director of Iowa State's Center for the Study of Violence, kids in both the U.S. and Japan who reported playing lots of violent video games had more aggressive behavior months later than their peers who did not, which appears in the November issue of the journal Pediatrics.

Then, while we get to the root of the problem and especially those who disagree with the statement might come upon this question, do children become more aggressive after playing video games or are aggressive kids more attracted to violent videos?

While this issue remains murky and controversial, there have been many studies that linked violent games to violent behaviours in kids.

One of the studies done by Dr. Anderson included three groups of kids; 181 Japanese students ages 12 to 15; 1,050 Japanese students aged 13 to 18; and 364 U.S. kids ages 9 to 12.

Japanese children rated their own behavior in terms of physical aggression, such as hitting, kicking or getting into fights with other kids; the U.S. children rated themselves too, but the researchers took into account reports from their peers and teachers as well.

In every group, children who were exposed to more video game violence did become more aggressive over time than their peers who had less exposure

What they found was that in all three samples, a lot of violent video game played early in a school year leads to higher levels of aggression during the school year, as measured later in the school year even after the kids were controlled how aggressive they were at the beginning of the year.

He also says that exposure to violent video games directly causes increased aggressive thoughts and behavior, and decreased empathy and prosocial behavior in the youths exposed to them. Anderson's team says these study conclusions hold true across geographies, cultures, and study methods.

they can now say with utmost confidence that regardless of research method, that is experimental, correlational, or longitudinal, and regardless of the cultures tested in this study [East-Japan and West-U.S], he get the same effects; that exposure to violent video games increases the likelihood of aggressive behavior in both short-term and long-term contexts.

Firstly, we have to understand the meaning of Responsible. Different people have various interpretation of the word responsible. In my point of view, responsible means “ being the primary course of something and so be able to be blamed or credited for it”. Therefore, I agree with the debate motion ‘ Violent games are responsible for aggressive behavior in teenagers’.

Violent video games have been available to consumers for the last 30 years. They are usually sandbox-styled. They are unique because they encourage players to become of the game’s ‘script’. Players are instigated to actively participate as a character by choosing how they will interact with other characters including which weapons will be used while fighting or attacking other characters. Weapons often include guns, knives, RPG‘s, bombs and even items in our daily household deemed to be deadly in the wrong hands.

Today’s sophisticated video games require players to pay close attention to the game as compared to passively watching television or movie. As active participants in the game’s script players strongly portray themselves with violent characters portrayed in violent video games. This action of merging with characters in video games increases a player’s ability to learn and retain aggressive thoughts and behaviors they see being portrayed in violent games. Furthermore, exposure to violent video games may input angry and hostile feelings into the affected while interacting with peers, teachers and adults. Also, violent video games reward violence as an effective way to handle conflict hence when teenagers get into brawls, they result to violence as a settlement. Moreover studies by Albert Bandura, a psychologist in Mundare, Alberta, Canada Social Science in Psychology at Stanford University stated that rewarding violent behavior is conducive to learning. Due to this, players who are continually rewarded for violent responses may experience an increase in their aggressive behavior and/or their perception of aggressive behavior.

Thus, without a doubt, I agree that violent video games are responsible for instilling aggressive characteristics in teenagers.

I agree to this statement, 'Violent computer games are responsible for aggressive behaviour in teenagers' . I would like to make a point that my views of this argument is solely based on facts and researches.

Dr. Craig A. Anderson, Ph.D., of Iowa State University in Ames, and his colleagues looked at how teen’s video game habits at one time point related to their behavior three to six months later.

The study included three groups of kids: 181 Japanese students ages 12 to 15; 1,050 Japanese students aged 13 to 18; and 364 U.S. kids ages 9 to 12.

The U.S. children listed their three favorite games and how often they played them. In the younger Japanese group, the researchers looked at how often the children played five different violent video game genres (fighting action, shooting, adventure, among others); in the older group they gauged the violence in the kids' favorite game genres and the time they spent playing them each week.

Japanese children rated their own behavior in terms of physical aggression, such as hitting, kicking or getting into fights with other kids; the U.S. children rated themselves too, but the researchers took into account reports from their peers and teachers as well.

In every group, children who were exposed to more video game violence did become more aggressive over time than their peers who had less exposure. This was true even after the researchers took into account how aggressive the children were at the beginning of the study -- a strong predictor of future bad behavior.

I agree that violent computer games are responsible for aggressive behavior in teenagers. The reason for my stand is based on the following articles:

1.On November 29, 2010 in South Philadelphia, Pennsylvania, 16-year-old boy Kendall Anderson bludgeoned his mother to death in her sleep with a claw hammer after she took away his PlayStation.

2.In September 2007 in Ohio, 16-year-old Daniel Petric snuck out of his bedroom window to purchase the game Halo 3 against the orders of his father, a minister at New Life Assembly of God in Wellington, Ohio, U.S. His parents eventually banned him from the game after he spent up to 18 hours a day with it, and secured it in a lockbox in a closet where the father also kept a 9mm handgun, according to prosecutors. In October 2007, Daniel used his father's key to open the lockbox and remove the gun and the game. He then entered the living room of his house and shot both of them in the head, killing his mother and wounding his father. Petric is sentenced to life in prison without parole, which was later commuted to 23 years in imprisonment. Defense attorneys argued that Petric was influenced by video game addiction, the court dismissed these claims. The judge, James Burge commented that while he thought there was ample evidence the boy knew what he was doing, Burge thought the game had affected him like a drug, saying "I firmly believe that Daniel Petric had no idea at the time he hatched this plot that if he killed his parents they would be dead forever."

3.On June 25, 2003, two American step brothers, Joshua and William Buckner, aged 14 and 16, respectively, used a rifle to fire at vehicles on Interstate 40 in Tennessee, killing a 45-year-old man and wounding a 19-year-old woman. The two shooters told investigators they had been inspired by Grand Theft Auto games.

The actions of the teens were incited by the video games. Therefore, it is apparent to me that violent computer games are responsible for aggressive behavior in teenagers.

I agree that violent video games are responsible for teenage violence,however this refers to the general population of teenagers that are avid gamers of violent video games.

According to an article from http://ithp.org/articles/violentvideogames.html

"97% of 12-17 year olds in the US played video games in 2008, thus fuelling an $11.7 billion domestic video game industry. In 2008, 10 of the top 20 best-selling video games in the US contained violence.Violent video games have been blamed for school shootings, increases in bullying, and violence towards women. Critics argue that these games desensitize players to violence, reward players for simulating violence, and teach children that violence is an acceptable way to resolve conflicts. " This shows the statistics to prove that there is a large amount of influence readily available to the teenage population in America. With such influence readily available, these avid gamers are exposed to violent media, these violent media often influence gamers and ause aggressive behavior in them.

The main objectives in these violent games is mainly to kill, and with successful killings, the gamers feel a sense of accomplishment. They then get addicted to this sense of accomplishment and implement violent behavior towards others to get a sense of accomplishment.

"Researchers at the Indiana University School of Medicine say that brain scans of kids who played a violent video game showed an increase in emotional arousal – and a corresponding decrease of activity in brain areas involved in self-control, inhibition and attention.(attached link) Mathews and his colleagues chose two action games to include in their research -- one violent the other not.

The first game was the high-octane but non-violent racing game “Need for Speed: Underground.” The other was the ultra-violent first-person shooter “Medal of Honor: Frontline.”

The team divided a group of 44 adolescents into two groups, and randomly assigned the kids to play one of the two games. Immediately after the play sessions, the children were given MRIs of their brains.

The scans showed a negative effect on the brains of the teens who played “Medal of Honor” for 30 minutes. That same effect was not present in the kids who played “Need for Speed.”

The only difference? Violent content.

What’s not clear is whether the activity picked up by the MRIs indicates a lingering — or worse, permanent — effect on the kids’ brains.

And it’s also not known what effect longer play times might have. The scope of this study was 30 minutes of play, and one brain scan per kid, although further research is in the works."

There has been scientific evidence to support my stand, the attached link clearly shows a large difference between the two MRI scans, this proves that violent video games have negative effects

I would like to agree to the topic that violent video games are responsible for aggressive behavior in children and teenagers.

An example would be two teenagers, Dylan Klebold and Eric Harris from Columbine high school. After playing the violent video game, grand theft auto, the two boys got seriously addicted to it. Unable to separate the virtual world from reality, they decided to imitate the video game's action and follow their actions in reality.

What they did was to try to plant bombs in the school and try to destroy the school. This plan was derived after thinking that the school is an enemy hideout.In grand theft auto, you are supposed to destroy your enemies headquarters by either shooting the people inside or destroying the whole building with bombs. At first, their bombs did not manage to get detonated so they decided to charge in with guns to kill the students which they thought were triad members from another mafia group so they charged into the school's cafeteria killing 13 and injuring 24. From this example, we could conclude that violent computer games are responsible for aggressive behavior in children or teenagers.

I agree with the debate motion stating that violent video games are responsible for aggressive behavior in teenagers.

One of the main concerns that has constantly been raised against video games is that most of the games feature aggressive elements. This has led many people to assert that this may have a detrimental effect on individuals who play such games. The one consistent finding is that the majority of the studies on very young children—as opposed to those in their teens upwards—tend to show that children do become more aggressive after either playing or watching a violent video games.

Video games have been available to consumers for the last 30 years. They are unique because they encourage players to become a part of the game's script. Players are encouraged to actively participate as a character by choosing how they will interact with other characters including which weapons will be used while fighting or attacking other characters. Weapons often include guns, knives, pipes, bombs, etc. Due to consumer demand over the last three decades, most video games produced and sold today are violent. Today's sophisticated video games require players to pay constant attention to the game as compared to passively watching television or a movie. As active participants in the game's script players strongly identify with violent characters portrayed in violent video games. This identification with characters in video games increases a player's ability to learn and retain aggressive thoughts and behaviors they see portrayed in violent games. Further research has suggested that exposure to violent video games may increase angry and hostile feelings while interacting with peers, teachers, and adults. Violent video game exposure may decrease compassionate feelings for others with whom they interact. In addition, the National Television Violence Study (1996) determined that 73 percent of violent video games reward violence as an effective way to handle conflict. Studies conducted by Bandura and Berkowitz have found that rewarding violent behavior is conducive to learning. As a result, players who are continually rewarded for violent responses may experience an increase in their aggressive behavior and/or their perception of aggressive behavior (Bandura, 1977; Berkowitz, 1993). This might in turn make these people think that they would somehow be 'rewarded' for doing things like killing due to them being rewarded in those games itself in the first place. This can also make them think that this is 'the right thing' to do. We are being punished for our various wrong-doings. However, instead of being punished in those games, they are being rewarded and praised! This can thus feel that by doing all these acts, they might feel rewarded and superior. Hence, an increase in violent behaviors and thoughtless actions.

In their book, Violent Video Game Effects on Children and Adolescents. Anderson, Gentile, and Buckley provide an in depth analysis some recent studies they conducted.

The first study was a cross-sectional correlational study of media habits, aggression-related individual difference variables, and aggressive behaviors of an adolescent population. 189 high school students completed surveys about their violent TV, movie, and video game exposure, attitudes towards violence, and perceived norms about violent behavior and personality traits. After statistically controlling for sex, total screen time and aggressive beliefs and attitudes, the authors found that playing violent video games predicted heightened physically aggressive behavior and violent behavior in the real world in a long-term context.

In the next study, Anderson et al conducted a longitudinal study of elementary school students to examine if violent video game exposure resulted in increases in aggressive behavior over time. Surveys were given to 430 third, fourth, and fifth graders, their peers, and their teachers at two times during a school year. The survey assessed both media habits and their attitudes about violence. Results indicated that children who played more violent video games early in a school year changed to see the world in a more aggressive way and also changed to become more verbally and physically aggressive later in the school year. Changes in attitude were noticed by both peers and teachers.

Thus, I conclude that violent video games ARE responsible for aggressive behavior in teenagers.

I agree that violent video games are responsible for teenage violence.

Many teenagers plays video games. They will stay up all night and try to go up a new level and usually they will not rest until they reach their goal. There has also been cases where the gamer refuses to eat with their family and take very short baths so that they have more time to game. This affects their mental and physical health. Without proper food and rest, the gamer will be weaker and emotionally unstable as he/her is often tired. The gamer will get sick more often and hence they will miss many days of school. Usually these people will spent their time on the computer instead. That increases the time gamers spent on the computer. Their academic results would drop drastically too. Their parents would be disappointed in them and most likely nag or scold them. The gamers too, might be disappointed in his/her own self. This will lead to many stress and frustrations as the gamers are already addicted to the game and cannot stop playing.

Everyone deals with stress and frustrations differently. This happens usually after the game character has been defeated or other players around the world has offended him/her in a way or another. However when action is taken upon the frustration and stress, and the action is taken out in anger and aggression, the results may be very harmful to both the aggressor and the person being aggressed against, mentally, emotionally, and even physically. Aggression is action, i.e. attacking someone or a group with an intent to harm someone. It can be a verbal attack--insults, threats, sarcasm, or attributing nasty motives to them--or a physical punishment or restriction. Direct behavioural signs include being overly critical, fault finding, name-calling, accusing someone of having immoral or despicable traits or motives, nagging, whining, sarcasm, prejudice, and/or flashes of temper. The crime and abuse rate in the United States has soared in the past decade. More and more children suffer from and are being treated for anger management than ever before. As gamers meet and play with other gamers from the world, They will not know who they are playing with hence they will not know if the person is easily offended or not.

Swear words are often seen on the net as a form of expression or aggression. This often leads to a quarrel on the net if the gamer is not careful with the words they are using. However, these gamers are not fearful or afraid of what might happen as they are anonymous. Which means that the other gamer will not know their particulars and hence not able to do anything to them. Even if the other gamer adds that gamer on Facebook, They will most probably be in different countries and it is not worth the money to fly to the other end of the Earth in search for the offensive gamer.

Hence, i agree that violent video games are responsible for teenage violence

I agree to the point that violent video games are responsible for the aggressive behavior that teenagers have.

On April 20, 1999, Eric Harris and Dylan Klebold launched an assault on Columbine High School in Littleton, Colorado, murdering 13 and wounding 23 before turning the guns on themselves. Although nothing is for certain as to why these boys did what they did, we do know that Harris and Klebold both enjoyed playing the bloody, shoot-'em-up video game Doom, a game licensed by the U.S. military to train soldiers to effectively kill. The Simon Wiesenthal Center, which tracks Internet hate groups, found in its archives a copy of Harris' web site with a version of Doom. He had customized it so that there were two shooters, each with extra weapons and unlimited ammunition, and the other people in the game could not fight back. For a class project, Harris and Klebold made a videotape that was similar to their customized version of Doom. In the video, Harris and Klebold were dressed in trench coats, carried guns, and killed school athletes. They acted out their videotaped performance in real life less than a year later. This case shows that teenagers learn from what they see and interact with, and violent video games are what caused this.

This other study shows that college students also have problems that are caused by violent video games. In the second study, 210 college students were allowed to play Wolfenstein 3D, an extremely violent game, or Myst, a nonviolent game. After a short time, it was found that the students who played the violent game punished an opponent for a longer period of time compared to the students who played the non violent game. Dr. Anderson concluded by saying, "Violent video games provide a forum for learning and practicing aggressive solutions to conflict situations. It the short run, playing a violent video game appears to affect aggression by priming aggressive thoughts." Despite the fact that this study was for a short term effect, longer term effects are likely to be possible as the player learns and practices new aggression-related scripts that can become more and more accessible for the real-life conflict that may arise.

These studies have shown that aggressive behaviour are caused by the type of games they play or things they interact with.

i would like to humbly agree that violent game are responsible for aggressive behavior in teenager.

Everyone deals with stress and frustrations differently. However when action is taken upon the frustration and stress, and the action is taken out in anger and aggression, the results may be very harmful to both the aggressor and the person being aggressive against, mentally, emotionally, and even physically. Aggression is action, i.e. attacking someone or a group with an intent to harm someone.

More and more children suffer from and are being treated for anger management than ever before. Now, one can't help but to wonder if these violent video games are even playing a slight part in the current statistics.

i would like to emphasis on this point.violent game is a game where people kill their opponent and earn point. For those aggressive teenagers, when playing this type of violent game, they can kill and earn point to their heart content. these aggressive people enjoy the bloody scene and gun shot of that violent game.Normally if these opponent in that game died, they would revive again wheres in the real world , such things would never happen.these would give those aggressive teenager evil thoughts of how to harm the person cruelly like how he kill his opponents in the violent game.

Calvert and Tan compared the effects of playing versus observing violent video games on young adults' arousal levels, hostile feelings, and aggressive thoughts. Results indicated that college students who had played a violent virtual reality game had a higher heart rate, reported more dizziness and nausea, and exhibited more aggressive thoughts in a post test than those who had played a nonviolent game do. A study by Irwin and Gross sought to identify effects of playing an "aggressive" versus "non aggressive" video game on second-grade boys identified as impulsive or reflective. Boys who had played the aggressive game, compared to those who had played the non aggressive game, displayed more verbal and physical aggression to inanimate objects and playmates during a subsequent free play session. Moreover, these differences were not related to the boys' impulsive or reflective traits. Thirdly, Kirsh also investigated the effects of playing a violent versus a nonviolent video game. After playing these games, third- and fourth-graders were asked questions about a hypothetical story. On three of six questions, the children who had played the violent game responded more negatively about the harmful actions of a story character than did the other children. These results suggest that playing violent video games may make children more likely to attribute hostile intentions to others.

From what kirsh investigation, even pure and innocent children could fall inside the violent game"trap" and thus making children more likely to attribute hostile intentions to others.violent game could encourage a non aggressive person to a aggressive person. what about those who are already aggressive and after playing those violent game, it could enable their behavior to be more aggressive.

Thus i strongly agree that Violent computer games are responsible for aggressive behavior in teenagers .

i honorably agree that Violent computer games are responsible for aggressive behavior in teenagers.

Excessive violence in video games has many significant negative effects on children and teenagers. The nature of today's gaming market doesn't seem to help the situation at all. Every year, hundreds of new games are released into stores, adding to an already abundant library of blood and gore, which leads to a decrease in the price of previous years' games. In addition, since the price of CDs and game related hardware is on the decline, it is becoming easier and more economical for children and teenagers to play these games in the comfort of their own home, instead of paying hourly fees at Local area network gaming centers. The latter allows gamers to spend much more time in front of their consoles, since they are shielded from the common distractions of PC rooms. By combining the latter reality with the fact that violent video games are the most popular type of games among children and teenagers, we can see that this is an ever growing problem (Bushman, 2005).

On the 11th of March 2009, Tim Kretshmer in camouflage, hijacked a car, and then took out his 9mm baretta unleashing a shooting rampage, killing 15 of his classmates in his school in Wennenden, Germany. This scenario is eerily similar to the video game "Far Cry 2", where the main character also uses camouflage as attire and goes around in his car shooting and killing people. Investigations of the incident revealed that 6 hours before the "massacre", Kretshmer had just finished playing a marathon of "Far Cry 2" under the user name "Jawspredator1".

Three major negative effects are manifested in the majority of gamers who play violent video games. To begin with, gamers show a weakening in their pro social behavior, which include poorer relationships and drug related problems. Secondly, users start to exhibit violent behavior which can manifest itself in their thoughts or physically. Finally, desensitization, the loss of proper response to violent images, also lurks behind these games.

violent video games are most infamous for triggering both aggressive feelings and behavior. The proverb "violence breeds violence" best describes the results of numerous studies. Research has shown that teenagers are more likely to kick, fight and hit their peers due to playing violent video games for as low as 13 hours of gaming per week. Increase in quarrels between students and their teachers have also been observed (Harding, 2009). In one study, secondary students were divided into 2 groups. One group was allowed to play violent video games for 25 minutes, before being released to the play ground for recess. The second group of students played for 25 minutes adventure and puzzle games that lacked any violent scenes or elements whatsoever . After being let out, their actions were recorded. Over the course of the study, the researchers discovered that some teenagers actually yelled more often, were more physical with one another (pushing, kicking etc...) and even got into more fights than those who played the non violent games (Ihori et.al. , 2007).

From these information we can conclude that how harmful is violent game.it enable aggressive behavior , anti social in teenagers. it also encourage violent behavior such as kicking fighting more often. this could "corrupt" those teenagers mind as they are still young , and if this continue for a long period of time, there would be heavy consequences to pay.

thus i believe that Violent computer games are responsible for aggressive behavior in teenagers

I do agree that violent video/computer games are responsible for aggressive behavior in children and teenagers. As we see, before all this violent video/computer games were created, there was not even one case where a teenager becomes violent and dangerous to other people which can even lead to deaths of innocent people. As you see, there are some proofs that violent video/computer games are responsible for aggressive behavior in teenagers. One is that as far as we know, these violent video games are based on a reward system like when we kill 10 people, we get a bonus or when we kill 50 people and so. So, kids who are always playing violent games will soon enough get used to this reward system hence trying to apply it to real life. This is when cases where people are getting murdered by teenagers happen. An example of such cases would be back in 1999 at Colorado high school where two ordinary teens named Dylan Klebold and Eric Harris opened fire where 20 people got shot and 13 of them dead. Then, the media soon told the public that the two teenagers often played violent video games such as DOOM and others. Hence this really do prove that violent video games are responsible for aggressive behavior in children and teenagers.

I agree that violent computer games are responsible for aggressive behaviour in teenagers. There is a huge hype surrounding the launch of every new game system - Game Cube, XBox, and Sony Playstation 2 being just few of the latest. Affecting children age 4 all the way to 45 year-old adults, these video games have called for concern in our society regarding issues such as addiction, depression, and even aggression related to the playing of video games. A recent study of children in their early teens found that almost a third played video games daily, and that 7% played for at least 30 hours a week, this shows that there has been a serious sign, telling people that more teens are playing games instead of studying, looking at violent video games. What is more, some of these games being played like Mortal Combat, Marvel Vs. Capcom, and Doom are very interactive in the violence of slaughtering the opponent. The video game industries even put signs like "Real-life violence" and "Violence level - not recommended for children under age of 12" on their box covers, arcade fronts, and even on the game CDs themselves, however people ignored their warning and hence started playing those violent games which affects the teens thinking.

In the modern popular game Goldeneye 007 bad guys no longer disappear in a cloud of smoke when killed. Instead they perform an elaborate maneuver when killed. For example, those shot in the neck fall to their knees and then face while clutching at their throats. Other games such as Unreal Tournament and Half-Life are gorier. In these games when characters get shot a large spray of blood covers the walls and floor near the character, and on the occasions when explosives are used, the characters burst into small but recognizable body parts, once teens look at those images, there may be thinking that it is right to do that, nothing is wrong, which may affect their thinking and thoughts. In spite of the violence, the violent video games are also the more popular games on the market, this shows that majority of them have been played by teens. When video games first came out, indeed they were addictive... however, there seems to be a strong correlation now between the violent nature of games these days and the aggressive tendencies in game players, misleading them.

One example of such cases: On April 20, 1999, Eric Harris and Dylan Klebold launched an assault on Columbine High School in Littleton, Colorado, murdering 13 and wounding 23 before turning the guns on themselves. Although nothing is for certain as to why these boys did what they did, we do know that Harris and Klebold both enjoyed playing the bloody, shoot-'em-up video game Doom, a game licensed by the U.S. military to train soldiers to effectively kill. The Simon Wiesenthal Center, which tracks Internet hate groups, found in its archives a copy of Harris' web site with a version of Doom. He had customized it so that there were two shooters, each with extra weapons and unlimited ammunition, and the other people in the game could not fight back. For a class project, Harris and Klebold made a videotape that was similar to their customized version of Doom. In the video, Harris and Klebold were dressed in trench coats, carried guns, and killed school athletes. They acted out their videotaped performance in real life less than a year later. Hence i would conclude that the video games itself give them a wrong mindset, did not give them a warning.

Another example:

In another study by Karen E. Dill, Ph.D. & Craig A. Anderson, Ph.D., violent video games were considered to be more harmful in increasing aggression than violent movies or television shows due to their interactive and engrossing nature.The two studies showed that aggressive young men were especially vulnerable to violent games and that even brief exposure to violent games can temporarily increase aggressive behavior in all types of participants.

The first study was conducted with 227 college students with aggressive behavior records in the past and who completed a measure of trait aggressiveness. They were also reported to have habits of playing video games. It was found that students, who reported playing more violent video games in junior and high school, engaged in more aggressive behavior. In addition, the time spent playing video games in the past were associated with lower academic grades in college, which is a source of frustration for many students, a potential cause for anger and aggression. Hence I would like to agree with this statement.

I would like to respectfully disagree with what phyllis has just said. She claimed that surveys were carried out on the topic. Although there were many results and findings, there was nothin stating who was the survey specifically conducted by. You only stated several marketing companies. But,are this really well known company or is it an unreliable company? Due to this ambiguity, the sorce may be inaccurate and untrue so i would like to disagree to your point

Yes, I agree that violent video games are responsible for aggressive behaviours in children and teenagers.

Violent video games cause behavior problems, because constant exposure to violence desensitizes the player. This exposure to violence also acclimates the player to performing violent acts in real life. When children and teenagers, participate in violent video games, they become immune to the true impact of violent behaviour. As violence in video games has no negative consequences and offers "winning" as a reward, they lose the ability to empathize with the victim and are encouraged to think that violence causes no harm to others. Then, it is very easy to transfer this video/game violence to real violence.

According to a research done by scientist in the year 2011, playing violent video games does cause players to become more aggressive. The findings of a new University of Missouri (MU) study provide one explanation for why this occurs: the brains of violent video game players become less responsive to violence, and this diminished brain response predicts an increase in aggression.

"Many researchers have believed that becoming desensitized to violence leads to increased human aggression. Until our study, however, this causal association had never been demonstrated experimentally," said Bruce Bartholow, associate professor of psychology in the MU College of Arts and Science.

During the study, 70 young adult participants were randomly assigned to play either a non-violent or a violent video game for 25 minutes. Immediately afterwards, the researchers measured brain responses as participants viewed a series of neutral photos, such as a man on a bike, and violent photos, such as a man holding a gun in another man's mouth. Finally, participants competed against an opponent in a task that allowed them to give their opponent a controllable blast of loud noise. The level of noise blast the participants set for their opponent was the measure of aggression.

The researchers found that participants who played one of several popular violent games, such as "Call of Duty," "Hitman," "Killzone" and "Grand Theft Auto," set louder noise blasts for their opponents during the competitive task (this shows that they were more aggressive) than participants who played a nonviolent game. In addition, for participants that had not played many violent video games before completing the study, playing a violent game in the lab caused a reduced brain response to the photos of violence (which is an indicator of desensitization). Moreover, this reduced brain response predicted participants' aggression levels: the smaller the brain response to violent photos, the more aggressive participants were. Participants who had already spent a lot of time playing violent video games before the study showed small brain response to the violent photos, regardless of which type of game they played in the lab.

This study shows that violent games does affect children and teenagers’ mentality and it increases the chance of them to have aggressive behaviours. Thus, violent video games desensitize the players to actual violent acts.

I would like to humbly disagree with the respectable speaker(nigeltham) of the proposition team. You brought up a specific case of violent games causing teenagers to behave aggressively. However, I believe that this is a case of extremity and not all teenagers would behave this way due to violent games. You cannot blindly judge the entire teenage population simply based on a single case. I think this is definitely an unfair judgement based on limited facts. Many teenagers can be exposed to these violent games but are still very disciplined in reality. Perhaps the two boys mentioned in the example were already inherent by violent nature way before the episode of actual violence, the computer games could just be a trigger to their violence but does not initiate their pre-existing violent nature.

I play video games myself. I play all types. Horror,Violence,Adventure..You name it. BUT I am NOT aggressive at all , and neither are any of my other gaming friends. In fact , I know a lot of people that game. They aren't aggressive either. I believe video games that involve fighting improve hand and eye coordination , better instincts , and they're amusing.

This statement is over.

Violent video games put ideas in children's mind that they wouldn't normally have thought of on their own. Most kids don't think about stabbing, shooting others, etc. with blood gushing all over the place. Violent games sometimes show the gamer that it's easy to solve your problems by using force. When kids play games like these the violent images/thoughts from these games can stay with them and if they idolized any of the characters from the game they might be tempted to try and imitate them in rl too. Kids really do love to imitate and can be very impressionable.

According to a new long-term study done by Brock university in Canada, teenagers who play violent video games over a number of years become more aggressive towards other people. That's why I agree that violent computer games result in more aggressive teens. For example, Callum Green fourteen years old teenager from Stockport, hanged himself after playing Call of Duty. In view that it will be better if teenagers stop playing such games. I believe that there a direct relationship between violent video games and aggressive behaviour

If a young child plays them, it creates a subconcious imprint of violence=reward. So, kill, kill, kill= level up and no killing= you get killed.

I agree that violent computer games are responsible for aggressive behaviour in teenagers.

Based on a article by Anne Harding from CNN. "About 90 percent of U.S. kids ages 8 to 16 play video games, and they spend about 13 hours a week doing so (more if you're a boy). Kids in both the U.S. and Japan who reported playing lots of violent video games had more aggressive behavior months later than their peers who did not, according to the new study, which appears in the November issue of the journal Pediatrics.In the new study, Dr. Craig A. Anderson, Ph.D., of Iowa State University in Ames, and his colleagues looked at how children and teen's video game habits at one time point related to their behavior three to six months later.

The study included three groups of kids: 181 Japanese students ages 12 to 15; 1,050 Japanese students aged 13 to 18; and 364 U.S. kids ages 9 to 12.

The U.S. children listed their three favorite games and how often they played them. In the younger Japanese group, the researchers looked at how often the children played five different violent video game genres (fighting action, shooting, adventure, among others); in the older group they gauged the violence in the kids' favorite game genres and the time they spent playing them each week.

Japanese children rated their own behavior in terms of physical aggression, such as hitting, kicking or getting into fights with other kids; the U.S. children rated themselves too, but the researchers took into account reports from their peers and teachers as well.

In every group, children who were exposed to more video game violence did become more aggressive over time than their peers who had less exposure. This was true even after the researchers took into account how aggressive the children were at the beginning of the study -- a strong predictor of future bad behavior."

This shows that violent computer games does and will affect teenagers in having aggressive behaviour. Thus, it is responsible.
