Immersed in violence: How 3-D gaming affects video game players

 


Researchers found that people who played violent video games in 3-D showed more evidence of anger afterward than did people who played using traditional 2-D systems -- even those with large screens.

Playing violent video games in 3-D makes everything seem more real -- and that may have troubling consequences for players, a new study reveals.

Researchers found that people who played violent video games in 3-D showed more evidence of anger afterward than did people who played using traditional 2-D systems -- even those with large screens.

The higher anger in 3-D players was connected to the fact that, compared to 2-D players, they were more likely to feel they were "immersed in the game," said Brad Bushman, co-author of the study and professor of communication and psychology at The Ohio State University.

"3-D gaming increases anger because the players felt more immersed in the violence when they played violent games," said Bushman. "As the technology in video games improves, it has the ability to have stronger effects on players."

Bushman conducted the study with lead author Robert Lull, a graduate student in communication at Ohio State. They announced their findings on Sunday (10/19) during the New Horizons in Science briefings at ScienceWriters2014, an annual conference hosted this year by Ohio State.

Bushman discussed these new results as part of his presentation "Guns, gender, race and violent video games: Searching for the roots of modern aggression."

The study has been accepted for publication in the journal Psychology of Popular Media Culture.

Participants were 194 college students, about two-thirds of whom were women. All of the students played the video game Grand Theft Auto IV for 15 minutes. Half were instructed to play violently (kill as many people as possible in the game) and half played nonviolently (they went bowling).

They played on a 17-inch 2-D screen, a 96-inch 2-D screen or on a 96-inch 3-D screen while wearing appropriate 3-D glasses.

Later, all participants reported their mood on a variety of dimensions, including anger. For example, they were asked to rate how angry, annoyed and furious (among other adjectives) they felt on a scale of 1 to 5.

Results showed that for those who played nonviolently, it didn't matter if they played in 2-D or 3-D -- their levels of anger were relatively low and unchanged.

Those who played violently showed higher levels of anger than nonviolent players no matter how they played, 2-D or 3-D. But those who played violently on 3-D were significantly angrier than those who played violently on the 2-D systems.

Why did those who play violently in 3-D show more anger? Another result from the study gives the answer.

After playing the games, participants were asked several questions measuring how immersed they were in the game. For example, they were asked to rate on a scale of 1 to 7 how much they felt they "were really 'there' in the game environment" and how much they felt like other characters in the game were real.

Results showed that people who played in 3-D felt more immersed in the game than did those who played in 2-D, and that immersion was related to the increased anger felt by those who played violently.

"The combination of violent content and immersive technology like 3-D can be troublesome," Bushman said.

"This is something that needs to be considered by everyone involved -- electronics manufacturers, video game developers, consumers, parents and content ratings agencies."

Action video games bolster sensorimotor skills, study finds

 


One of the benefits of playing action games may be an enhanced ability to precisely learn the dynamics of new sensorimotor tasks. Such skills are key, for example, in laparoscopic surgery which involves high precision manual control of remote surgery tools through a computer interface.

University of Toronto study finds that action video games bolster sensorimotor skills

A study led by University of Toronto psychology researchers has found that people who play action video games such as Call of Duty or Assassin's Creed seem to learn a new sensorimotor skill more quickly than non-gamers do.

A new sensorimotor skill, such as learning to ride a bike or typing, often requires a new pattern of coordination between vision and motor movement. With such skills, an individual generally moves from novice performance, characterized by a low degree of coordination, to expert performance, marked by a high degree of coordination. As a result of successful sensorimotor learning, one comes to perform these tasks efficiently and perhaps even without consciously thinking about them.

"We wanted to understand if chronic video game playing has an effect on sensorimotor control, that is, the coordinated function of vision and hand movement," said graduate student Davood Gozli, who led the study with supervisor Jay Pratt.

To find out, they set up two experiments. In the first, 18 gamers (those who played a first-person shooter game at least three times per week for at least two hours each time in the previous six months) and 18 non-gamers (who had little or no video game use in the past two years) performed a manual tracking task. Using a computer mouse, they were instructed to keep a small green square cursor at the centre of a white square moving target which moved in a very complicated pattern that repeated itself. The task probes sensorimotor control, because participants see the target movement and try to coordinate their hand movements with what they see.

In the early stages of doing the tasks, the gamers' performance was not significantly better than non-gamers. "This suggests that while chronically playing action video games requires constant motor control, playing these games does not give gamers a reliable initial advantage in new and unfamiliar sensorimotor tasks," said Gozli.

By the end of the experiment, all participants performed better as they learned the complex pattern of the target. The gamers, however, were significantly more accurate in following the repetitive motion than the non-gamers. "This is likely due to the gamers' superior ability in learning a novel sensorimotor pattern, that is, their gaming experience enabled them to learn better than the non-gamers."

In the next experiment, the researchers wanted to test whether the superior performance of the gamers was indeed a result of learning rather than simply having better sensorimotor control. To eliminate the learning component of the experiment, they required participants to again track a moving dot, but in this case the patterns of motion changed throughout the experiment. The result this time: neither the gamers nor the non-gamers improved as time went by, confirming that learning was playing a key role and the gamers were learning better.

One of the benefits of playing action games may be an enhanced ability to precisely learn the dynamics of new sensorimotor tasks. Such skills are key, for example, in laparoscopic surgery which involves high precision manual control of remote surgery tools through a computer interface.

The research was done in collaboration with Daphne Bavelier who has appointments with both the University of Geneva and the University of Rochester.

Their study is published in the journal Human Movement Science.
