Back to School in a Wired World
Are electronic gadgets turning kids into multitasking pros, or are they just dragging them down?
It's no secret that today's children are growing up in a brave new world of
computers, cell phones, video games, and iPods. This year, kids will head back
to school with more gadgets than ever before.
"Young people today live media-saturated lives, spending an average of
nearly 6 1/2 hours a day with media," according to a 2005 Kaiser Family
Foundation study, "Generation M: Media In the Lives of 8-
And that's not all. Gone are the days when a youngster sat too close to the
TV, lost in a favorite show. Nowadays, multiple gadgets may compete for a
child's scattered attention.
"Kids are instant-messaging while they're watching MTV and taking cell
phone calls and playing a computer game with somebody in Japan," says
Kathleen Clarke-Pearson, MD, a pediatrician and spokeswoman for the American
Academy of Pediatrics' Council on Communications and Media.
"This is a complete experiment in the history of childhood and in the
history of the human brain," says Jane M. Healy, PhD, an educational
psychologist and author of Failure to Connect: How Computers Affect Our
Children's Minds -- and What We Can Do About It.
Not sure how to help your children cope with all of the distractions and
dilemmas that the new technology brings? Here's some expert advice.
Q.My teenager does homework, listens to an iPod, and sends instant messages on the computer -- all at the same time. Could this multitasking hinder learning?
A. Yes, says Russell Poldrack, PhD, a University of California, Los Angeles,
associate professor of psychology. "When the goal is learning, it's
important to focus," he says. "Learning and memory are pretty badly
reduced when you're multitasking."
In one of Poldrack's studies, 14 adults (average age 26) had to learn a new
task while simultaneously listening to a series of beeps and counting only the
high tones. Poldrack discovered that this type of active multitasking impaired
the subjects' ability to learn.
In real life, a teen is engaged in active multitasking if he or she sends
text messages or talks on a cell phone while reading a textbook.
What's the result? "You sacrifice ability to focus and general
performance," Poldrack says. "One of the most fundamental and
widespread findings in psychology is that whenever you have to switch back and
forth between doing things, you're not as good at them as if you had focused on
them. The brain has some pretty fundamental limits in terms of its ability to
do multiple things at once."
