Violent Video Games Increase Aggression Long After the Game Is Turned Off, Study Finds

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).

Violent video game playing has long been known to increase aggression. This study, conducted by Brad Bushman of The Ohio State University and Bryan Gibson of Central Michigan University, shows that at least for men, ruminating about the game can increase the potency of the game's tendency to lead to aggression long after the game has been turned off.

The researchers randomly assigned college students to play one of six different video games for 20 minutes. Half the games were violent (e.g., Mortal Kombat) and half were not (e.g., Guitar Hero). To test if ruminating about the game would extend the games' effect, half of the players were told over "the next 24 hours, think about your play of the game, and try to identify ways your game play could improve when you play again."

Bushman and Gibson had the participants return the next day to test their aggressiveness. For men who didn't think about the game, the violent video game players tested no more aggressive than men who had played non-violent games. But the violent video game playing men who thought about the game in the interim were more aggressive than the other groups. The researchers also found that women who played the violent video games and thought about the games did not experience increased aggression 24 hours later.

This study is the first laboratory experiment to show that violent video games can stimulate aggression for an extended period of time. The authors noted that it is "reasonable to assume that our lab results will generalize to the 'real world.' Violent gamers usually play longer than 20 minutes, and probably ruminate about their game play in a habitual manner."

Sleep Makes Your Memories Stronger, and Helps With Creativity !

ScienceDaily (Dec. 17, 2010) — As humans, we spend about a third of our lives asleep. So there must be a point to it, right? Scientists have found that sleep helps consolidate memories, fixing them in the brain so we can retrieve them later. Now, new research is showing that sleep also seems to reorganize memories, picking out the emotional details and reconfiguring the memories to help you produce new and creative ideas, according to the authors of an article in Current Directions in Psychological Science.

"Sleep is making memories stronger," says Jessica D. Payne of the University of Notre Dame, who co-wrote the review with Elizabeth A. Kensinger of Boston College. "It also seems to be doing something which I think is so much more interesting, and that is reorganizing and restructuring memories."

Payne and Kensinger study what happens to memories during sleep, and they have found that a person tends to hang on to the most emotional part of a memory. For example, if someone is shown a scene with an emotional object, such as a wrecked car, in the foreground, they're more likely to remember the emotional object than, say, the palm trees in the background -- particularly if they're tested after a night of sleep. They have also measured brain activity during sleep and found that regions of the brain involved with emotion and memory consolidation are active.

"In our fast-paced society, one of the first things to go is our sleep," Payne says. "I think that's based on a profound misunderstanding that the sleeping brain isn't doing anything." The brain is busy. It's not just consolidating memories, it's organizing them and picking out the most salient information. She thinks this is what makes it possible for people to come up with creative, new ideas.

Payne has taken the research to heart. "I give myself an eight-hour sleep opportunity every night. I never used to do that -- until I started seeing my data," she says. People who say they'll sleep when they're dead are sacrificing their ability to have good thoughts now, she says. "We can get away with less sleep, but it has a profound effect on our cognitive abilities."

So sleep good friends !
