They Do It All While Studying

At homework time, many students also are playing games, e-mailing friends and watching TV. Scientists say that is bad for learning.

If you think peace, quiet and uninterrupted focus are the keys to good study habits, 16-year-old Ryan Arnold may prove you wrong.

While doing his homework, the North Carolina high school junior typically does at least four other tasks as well -- among them listening to music, playing a PlayStation 2 game, sending e-mail and surfing the Web.

"It drives me crazy," his mother, Cindy Hensley, said of her son's many activities. "I can't do it. I say, 'If I can't do it, then how can you do it?' But he's a straight-A student, so I guess he does."

Time was, homework meant hunkering down in the library or a quiet study carrel. Today, instead of seeking to minimize distractions while studying, a majority of children are embracing them, according to a Los Angeles Times/Bloomberg poll.

Among respondents who had homework, 53% of children ages 12 to 17 said they did at least one other thing while studying, compared with 25% of adults ages 18 to 24, the poll found.

The youngest poll respondents did the most juggling. Twenty-one percent of the 839 respondents ages 12 to 17 who were polled said they generally kept busy with at least three tasks in addition to their assignments.

Girls ages 15 to 17 were the busiest: 59% said they liked to do at least one thing in addition to homework, and 27% said they liked to do at least three other things.

"I'll focus on my schoolwork, then if an e-mail pops up I'll change focus for a second, answer it, then go back to what I was working on," said Brittany Graham, 16, who also likes to surf the Web and listen to Christian rock while she studies in her family's home in Altamonte Springs, Fla.

Kids' fondness for multi-tasking is raising concerns among psychologists and educators. They worry that students are taking longer to complete their assignments while absorbing less information than they would if they were focusing solely on schoolwork.

Some scientists fear that multi-tasking could even stunt the development of adolescent brains. The ability to give up instant gratification in favor of long-term goals, for example, is largely controlled by the prefrontal cortex, the brain's "executive center." That's the same area of the brain that, among other things, determines correct social behavior and steers attention from one task to another.

"In kids, the prefrontal cortex is still developing," said Jordan Grafman, chief of the cognitive neuroscience section at the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health. "Developing strength in one's ability to stall immediate gratification is part of growing up."

But repeatedly choosing video games or instant messages from friends over homework could hinder that, Grafman said. Additionally, multi-tasking can prevent students from learning subjects in great depth, which is a process that stimulates reasoning, analysis and foresight.

Ulla Foehr, who surveyed teens on media consumption for a Kaiser Family Foundation study released last year while she was a Stanford University doctoral student, notes that multi-tasking is not a new phenomenon. For decades, some kids have studied to music or while watching TV.

But the computer's role as both an educational tool and a means for diversion, all wrapped in the same package, increases the allure of doing several things at once. AOL, for example, on Thursday released, a search engine to help with homework, but it also offers plenty of time wasters, including instant messaging and video clips.

"The computer really fosters it. It makes it hard not to multi-task," Foehr said. "It's the availability, combined with the innate desire to take a break. For teens, it's really driven by the social needs, the need to connect with their peers."

Distraction isn't everyone's cup of tea, the poll found. More than 2 in 5 respondents ages 12 to 17 said they preferred to focus completely on their homework and didn't multi-task at all.

Among those in that same age group who did other things while studying, many reported relatively passive diversions. Eighty-four percent said they listened to music as a side activity, 47% watched TV and 22% watched a movie.

But teenage respondents also enjoyed multi-tasking with things that required active participation, the poll found, including talking on the phone (32%), going on the Internet (21%), instant messaging (15%), sending or reading e-mail (13%), text messaging (13%) and playing a video game (6%).

Many teenagers and their parents believe that this generation is simply better at performing simultaneous tasks, because they do it so often. To watch a child study biology while cruising, chatting with five buddies on AOL Instant Messenger and listening to the TV drone in the background is to begin to suspect that today's youngsters must have sharper focus than previous generations.
