Good news for people who have difficulty in remembering things. A memory technique invented by the ancient Greeks has recently been proved to be able to greatly improve ordinary people's memory ability. You may even become a memory champion if you practice hard enough.

This is according to a study published in the journal Neuron. Researchers fro

Radboud University Medical Center in the Netherlands found that memory champions aren't all that different to us. People with an average memory can greatly improve their memory ability by using what's known as the“ mind palace” method.

The method is the secret weapon (武器) of the fictional (虚构的) character Sherlock Holmes.

In order to do this, you need to picture a place you're familiar with, such as your living room. Then, you have to remember this place in as much detail as possible as this is your own mind palace.

Suppose you want to remember a shopping list. You can start by spreading out all the items around your living room in your mind. This means each item on your list is connected with a remembered place in your living room. You travel to that remembered place as you recall the list.

To explore the effects of this method on the brain, researchers gathered 51 participants with average memory levels and no previous memory training. After 40 days of daily 30-minute training sessions (一段时间), participants doubled the amount of words they could remember - they went from recalling an average of 26 words out of 72, to an impressive 62. Four months later, even without continued training, their recall performance remained high.

“Once you are familiar with these strategies and know how to apply them, you can keep your performance high without much further training,” Martin Dresler, assistant professor from Radboud University Medical Center, told the Daily Mail.

In addition, the training also affects the way our brain cells connect. After training, the way that the participants' brain cells connect began to be like those of memory champions compared to scans(扫描检查) taken before training. Researchers believe this could be responsible for their increased memory.

But what makes this research so fascinating is that it seems to prove that the talent to store things in your mind isn't down to genes. Dresler found there was no deference in brain structure between memory champions and normal people, which means memory champions are not born with different brains.

“They, without a single exception, trained for months and years using methods to achieve these high levels of performance,” Dresler told Science Daily.

It’s clear that more studies are needed to find out what's going on here, but the “mind palace” method might be your best bet to never forget an important name, date or appointment ever again.
