TV, Video Games May Increase Attention Problems
Kids who spend more time than their peers watching television or playing video games appear to be at greater risk for problems related to attention. Those children who exceeded the recommended amount of 2 hours per day of combined video games and TV viewing were nearly twice as likely to have above average attention problems.
“There isn’t an exact number of hours when screen time contributes to attention problems, but the AAP recommendation of no more than two hours a day provides a good reference point,” said Edward Swing, an Iowa State psychology doctoral candidate and lead researcher in the study.
“Most children are way above that. In our sample, children’s total average time with television and video games is 4.26 hours per day, which is actually low compared to the national average.”
The researchers assessed 1,323 children in third, fourth and fifth grades over 13 months, using reports from the parents and children about their video game and television habits, as well as teacher reports of attention problems. Another group of 210 college students provided self-reports of television habits, video game exposure and attention problems.
Previous research had associated television viewing with attention problems in children. The new study also found similar effects from the amount of time spent with video games.
“It is still not clear why screen media may increase attention problems, but many researchers speculate that it may be due to rapid-pacing, or the natural attention grabbing aspects that television and video games use,” Swing said.
Douglas Gentile, an associate professor of psychology at Iowa State University, reports that the pace of television programming has been quickened by “the MTV effect.”
“When MTV came on, it started showing music videos that had very quick edits — cuts once every second or two,” Gentile said. “Consequently, the pacing of other television and films sped up too, with much quicker edits.”
He says that quicker pace may have some brain-changing effects when it comes to attention span.
“Brain science demonstrates that the brain becomes what the brain does,” Gentile said. “If we train the brain to require constant stimulation and constant flickering lights, changes in sound and camera angle, or immediate feedback, such as video games can provide, then when the child lands in the classroom where the teacher doesn’t have a million-dollar-per-episode budget, it may be hard to get children to sustain their attention.”
The study showed that the effect was similar in magnitude between video games and TV viewing.
Based on the study’s findings, the researchers conclude that TV and video game viewing may be one contributing factor for attention deficit hyperactivity disorder (ADHD) in children.
Swing points out that the associations between attention problems and TV and video game exposure are significant, but small.
“It is important to note that television or video game time cannot solely explain the development of attention problems,” he said. “Clearly other factors are involved.”
The researchers plan to continue studying the effects of screen time on attention. They also hope future research can identify what aspects of television or video games may be most relevant to attention problems.
Two hours per day of screen time is the recommendation made by the American Academy of Pediatrics.
Their study will be published in the August print issue of Pediatrics available online on July 5.
