     In a six-week study, experts found people who played online games designed to improve their cognitive

(认知的) skills didn't get any smarter.

     More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers

to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week. They

were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of

time surfing the Internet and answering general knowledge questions. All participants were given a sort of

I.Q test before and after the experiment.

     Researchers said the people who did the brain training didn't do any better on the test after six weeks than

people who had simply been on the Internet. On some sections of the test, the people who surfed the Net

scored higher than those playing the games.

     "If you're (playing these games) because they're fun, that's absolutely fine," said Adrian Owen, the study's

lead author. "But if you're expecting (these games) to improve your I.Q., our data suggests this isn't the case,"

he said during a press briefing on Tuesday.

     One maker of brain games said the company's games have been proven to boost brain power. "Their

conclusion would be like saying, 'I cannot run a mile in under 4 minutes and therefore it is impossible to do

so," Aldrich said in a statement.

     "There is precious little evidence to suggest the skills used in these games transfer to the real world," said

Art Kramer, who was not linked to the study and has no ties to any companies that make brain training games.

     Instead of playing brain games, Kramer said people would be better off getting some exercise. He said

physical activity can spark (激发) new connections between nerves and produce new brain cells."Fitness

changes the building blocks of the brain's structure," he said.
