S-au scris lucrări despre felul în care televizorul ne „rescrie” creierul. I s-a spus mai apoi „tembelizor”. Pe bună dreptate. Sîntem cea mai informată generaţie care va fi trăit pe pămînt, dar cea mai deformată pe dinăuntru. Sîntem bombardaţi de imagini, dar fără imaginaţie şi putem continua cu observaţiile empirice. Ieri am dat peste un studiu care pare cel puţin interesant şi convingător, dacă nu foarte ştiinţific şi documentat.
Scientists say juggling e-mail, phone calls and other incoming information can change how people think and behave. They say our ability to focus is being undermined by bursts of information.
These play to a primitive impulse to respond to immediate opportunities and threats. The stimulation provokes excitement — a dopamine squirt — that researchers say can be addictive. In its absence, people feel bored.
The resulting distractions can have deadly consequences, as when cellphone-wielding drivers and train engineers cause wrecks. And for millions of people like Mr. Campbell, these urges can inflict nicks and cuts on creativity and deep thought, interrupting work and family life.
While many people say multitasking makes them more productive, research shows otherwise. Heavy multitaskers actually have more trouble focusing and shutting out irrelevant information, scientists say, and they experience more stress.
And scientists are discovering that even after the multitasking ends, fractured thinking and lack of focus persist. In other words, this is also your brain off computers.
“The technology is rewiring our brains,” said Nora Volkow, director of the National Institute of Drug Abuse and one of the world’s leading brain scientists. She and other researchers compare the lure of digital stimulation less to that of drugs and alcohol than to food and sex, which are essential but counterproductive in excess.
Technology use can benefit the brain in some ways, researchers say. Imaging studies show the brains of Internet users become more efficient at finding information. And players of some video games develop better visual acuity.
More broadly, cellphones and computers have transformed life. They let people escape their cubicles and work anywhere. They shrink distances and handle countless mundane tasks, freeing up time for more exciting pursuits.
For better or worse, the consumption of media, as varied as e-mail and TV, has exploded. In 2008, people consumed three times as much information each day as they did in 1960. And they are constantly shifting their attention. Computer users at work change windows or check e-mail or other programs nearly 37 times an hour, new research shows
Şi pentru meditaţii ulterioare iată aici un articol excelent din aceeaşi serie despre nerăbdare şi lipsa iertării.
Has high-speed Internet made you impatient with slow-speed children?
Do you sometimes think about reaching for the fast-forward button, only to realize that life does not come with a remote control?
If you answered yes to any of those questions, exposure to technology may be slowly reshaping your personality. Some experts believe excessive use of the Internet, cellphones and other technologies can cause us to become more impatient, impulsive, forgetful and even more narcissistic.
“More and more, life is resembling the chat room,” says Dr. Elias Aboujaoude, director of the Impulse Control Disorders Clinic at Stanford. “We’re paying a price in terms of our cognitive life because of this virtual lifestyle.”
We do spend a lot of time with our devices, and some studies have suggested that excessive dependence on cellphones and the Internet is akin to an addiction. Web sites like NetAddiction.com offer self-assessment tests to determine if technology has become a drug. Among the questions used to identify those at risk: Do you neglect housework to spend more time online? Are you frequently checking your e-mail? Do you often lose sleep because you log in late at night? If you answered “often” or “always,” technology may be taking a toll on you.
