The research, which included both elementary school-age and college-age participants, found that children who exceeded the two hours per day of screen time recommended by the American Academy of Pediatrics were 1.5 to 2 times more likely to be above average in 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."
Collaborating with Swing on the research were ISU's Douglas Gentile, an associate professor of psychology and Craig Anderson, a Distinguished Professor of psychology; and David Walsh, a Minneapolis psychologist. Their study will be published in the August print issue of Pediatrics -- the journal of the American Academy of Pediatrics -- available online on Monday, July 5.
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.
Gentile 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.TV, video games may contribute to ADHD
"ADHD is a medical condition, but it's a brain condition," Gentile said. "We know that the brain adapts and changes based on the environmental stimuli to which it is exposed repeatedly. Therefore, it is not unreasonable to believe that environmental stimuli can increase the risk for a medical condition like ADHD in the same way that environmental stimuli, like cigarettes, can increase the risk for cancer."
"Although we did not specifically study the medical condition of ADHD in these studies, we did focus on the kinds of attention problems that are experienced by students with ADHD," added Swing. "We were surprised, for example, that attention problems in the classroom would increase in just one year for those children with the highest screen time."
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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
