NY Times Thinks the gadgets are dumbing em down... you are correct. ...the effects of the deluge of data. Even after he unplugs, he craves the stimulation he gets from his electronic gadgets. He forgets things like dinner plans, and he has trouble focusing on his family. His wife, Brenda, complains, "It seems like he can no longer be fully in the moment."
This is your brain on computers.
Researchers say there is an evolutionary rationale for the pressure this barrage puts on the brain. The lower-brain functions alert humans to danger, like a nearby lion, overriding goals like building a hut. In the modern world, the chime of incoming e-mail can override the goal of writing a business plan or playing catch with the children.
"Throughout evolutionary history, a big surprise would get everyone's brain thinking," said Clifford Nass, a communications professor at Stanford. "But we've got a large and growing group of people who think the slightest hint that something interesting might be going on is like catnip. They can't ignore it."
...researchers were unsure whether the muddied multitaskers were simply prone to distraction and would have had trouble focusing in any era. But she added that the idea that information overload causes distraction was supported by more and more research.
...multitaskers took longer than non-multitaskers to switch among tasks, like differentiating vowels from consonants and then odd from even numbers. The multitaskers were shown to be less efficient at juggling problems.
Other tests at Stanford, an important center for research in this fast-growing field, showed multitaskers tended to search for new information rather than accept a reward for putting older, more valuable information to work.
The results also illustrate an age-old conflict in the brain, one that technology may be intensifying. A portion of the brain acts as a control tower, helping a person focus and set priorities. More primitive parts of the brain, like those that process sight and sound, demand that it pay attention to new information, bombarding the control tower when they are stimulated.
NOTE 2 SuperTechs: research shows some people can more easily juggle multiple information streams. These "supertaskers" represent less than 3 percent of the population, according to scientists.
