A
It doesn’t matter how clever you are or how much education you’ve had, you can still improve your mind. And improving your intelligence quotient(IQ) doesn’t have to mean studying hard. There are many methods that can help your brain. Here are three of them, from the British science magazine New Scientist.
Working memory
IQ is not decided by genetics. Some methods can help increase it.
Why: Until recently, a person’s IQ was thought to be determined by genetics. But recent studies suggest that a basic brain function called working memory could increase one’s IQ. Working memory is the brain’s short-term storage system. The amount of information the working memory can hold is related to general intelligence.
How: Training helps us expand the working memory. Common training tasks include: doing math questions that have intermediate(中间的) steps; remembering the position of objects on a map; or remembering a string of digits(数字), like a phone number, without writing it down.
Body and mind
Physical exercise can help the brain as well as the body. It’s good for those who hate studying hard.
Why: Physical exercise helps the growth of new brain cells. Until recently, it was believed that we produced no new brain cells in our lifetime. But, in 2000, US scientist Fred Gage showed that even adults could grow new brain cells. He also found that exercise was one of the best ways to achieve this.
How: Simply walking for half an hour three times a week can improve learning, concentration and reasoning by 15 percent. Even more gentle exercise like yoga can do good for your brain. A study last year showed that the best way to get a mental lift is to bend over backwards.
The Mozart effect
Music may tune up your thinking. But simply turning up the sound won’t make you clever.
Why: American scientist Frances Rauscher made waves by discovering in 1995 that listening to Mozart improved people’s mathematical reasoning. Last year, Rauscher reported that Mozart’s music seemed to increase activity in genes involved in nerve-cell signaling in the brain.
How: Listening to Mozart and taking music
