Using the internet and an obsession with e-mail are turning us into “lab rats”, an expert has claimed.
Nicholas Carr, former executive editor of the Harvard Business Review, said information overload is stopping people from concentrating on tasks as they search for “pellets of social interaction”.
The non-stop information overload also makes it impossible to think deeply, in a syndrome that has been christened Divided Attention Disorder, or DAD.
Carr, who wrote a book called The Shallows: What The Internet Is Doing To Our Brains, said that our basic instinct to search for new information makes us addicted to our inboxes. Many workers check their e-mail up to 30 times an hour.
“Our gadgets have turned us into hi-tech lab rats, mindlessly pressing levers in the hope of receiving a pellet of social or intellectual nourishment,” Carr told Esquire magazine.
“What makes digital messages all the more compelling is their uncertainty. There’s always the possibility that something important is... in our inbox… (which) overwhelms our knowledge that most online missives are trivial.”
He is just the latest expert to fear that the digital age may be having consequences on our brain’s health.
Recently, British neuroscientist Susan Greenfield said she believes constant computer and internet use may be “rewiring the brain”, shortening attention spans, encouraging instant gratification and causing a loss of empathy.
She believes technology may be behind the “alarming” rise in attention deficit hyperactivity disorder and the growth in the use of anti-hyperactivity drug Ritalin.
She warned that social networking sites such as Twitter and Facebook may hamper empathy.
Using search engines to find facts may hinder our ability to learn, while computer games in which it is always possible to start again may make us more reckless.
“We need to take control of our own lives and society. If we don’t, who else will?”
Maryanne Wolf, a cognitive neuroscientist at Tufts University in Massachusetts, said brain circuits honed by reading books and thinking about their contents could be lost as people spend more time on computers. “It takes time to think deeply about information and we are becoming accustomed to moving on to the next distraction,” she said. - Daily Mail
