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.

A proven method for effective textbook reading is the SQ3R method developed by Francis Robinson. The first is to survey (the S step) the chapter by reading the title, introduction, section headings, summary., and by studying any graphs, tables, illustrations or charts. The purpose of this step is to get an overview of the chapter so that you will know before you read what it will be about. In the second step (the Q step), for each section you ask yourself questions such as "What do I already know about this topic?" and "What do I want to know?" In this step you also take the section heading and turn it into a question. This step gives you a purpose for reading the section. The third step (the first of the 3 R's) is to read to find the answers to your questions. Then at the end of each section, before going on to the next section, you recite ( the second of the 3 R's) the answers to the questions that formed in the question step. When you recite you should say the information you want to learn out loud in your own words. The fifth step is done after you have completed step 2, 3 and 4 for each section. You review (the last of the 3 R's) the entire chapter. The review is done much as the survey was in the first step. As you review, hold a mental conversation with yourself as you recite the information you selected as important to learn. The mental conversation could take the form of asking and answering the questions formed the headings or reading the summary, which lists the main ideas in the chapter, and trying to fill in the details for each main idea.

D.While you are holding a mental conversation you select the important information. |
