Only Less Than 15 Minutes, Brain Already Recordable New Words
The brain will learn a new word in less than 15 minutes. Simply listen to these word as much as 160 times. According to scientists at the University of Cambridge, the brain will create new neural network to remember the word.
The findings of these scientists explain that the time it takes the brain to learn the words turned out to be much faster than expected.
Research done by placing electrodes on the head of 16 healthy volunteers. Their brain activity monitored during the test consisted of 2 stages.
In the first stage, the volunteers played on the words that are familiar. The second stage, they played on a foreign word that is called repeatedly.
At the beginning of the second phase, brain activity showed that the brain tries to recognize the word.But, after repeated 160 times in 14 minutes, brain activity can not be distinguished from brain activity in the first stage. "Virtually no difference," said Dr. Yury Shtyrov involved in research.
"To listen to alone is helpful to learn the language," says Dr. Shtyrov told The Telegraph. However, to say the word, need a new neural network, which is part of the brain that regulates speech.
However, this study does not aim to help tourists learn the language. According to Drs. Shtyrov, this research is to help restore the ability of stroke patients to speak.
To that end, the University of Cambridge took Cognition & Brain Sciences Unit of the Medical Research Council to develop an aphasia therapy that is named CIAT (Constraint-Induced Aphasia Therapy).
Aphasia is the loss of ability to speak due to illness, disability, or injury to the brain.
The next test will involve patients with stroke. As explained Dr. Shtyrov, rehabilitation can be faster by targeting parts of the brain for memory. "The key is repetition. The brain works better when the conditions relaxed and not trying to remember," he explained.
He gave an example in the field of sports. One can memorized the name of the players, teams, even good rules. "That's because every piece of information is always repeated and the people feel no need to memorize.
The brain can not memorize everything. Brain choose is important and the unimportant, "said Dr. Shtyrov.
