Your parents were right, don't study with the TV on. 你的父母是對(duì)的：學(xué)習(xí)時(shí)不要開(kāi)著電視。
Multitasking may be a necessity in today's fast-paced world, but new research shows distractions affect the way people learn, making the knowledge they gain harder to use later on.在如今快節(jié)奏的社會(huì)中，同時(shí)做幾件事也許是必須的，但新研究表明分心會(huì)影響人們的學(xué)習(xí)方式，使他們?nèi)蘸筝^難運(yùn)用到所學(xué)的知識(shí)。
"What's new is that even if you can learn while distracted, it changes how you learn to make it less efficient and useful," said Russell A. Poldrack, a psychology professor at the University of California, Los Angeles.洛杉磯加利福尼亞大學(xué)的心理學(xué)教授羅素?A?波德瑞克說(shuō)：“新的發(fā)現(xiàn)是即使你在受到干擾的情況下仍然可以學(xué)習(xí)，你的學(xué)習(xí)方式也會(huì)因此而改變，你的學(xué)習(xí)效率會(huì)變低，效果會(huì)變差。”
As Poldrack explains it, the brain learns in two different ways. One, called declarative learning, deals with learning active facts that can be recalled and used with great flexibility. The second is called habit learning.正如波德瑞克所解釋的那樣，大腦有兩種不同的學(xué)習(xí)方式，一種叫做敘述式學(xué)習(xí)，用來(lái)學(xué)習(xí)積極內(nèi)容，即人們可以回憶起來(lái)并能很靈活地加以運(yùn)用的東西。第二種叫習(xí)慣性學(xué)習(xí)。
For instance, in learning a phone number you can simply memorize it, using declarative learning, and can then recall it whenever needed.比方說(shuō)你記一個(gè)電話(huà)號(hào)碼，你可以直接通過(guò)敘述式學(xué)習(xí)方式把它記住，無(wú)論何時(shí)需要都能回憶起來(lái)。第二種就是習(xí)慣性地記住它。
"A second way to learn it is by habit, "punch it in 1,000 times, then even if you don't remember it consciously, you can go to the phone and punch it in," Poldrack said.“撥個(gè)1000次，不管你是否有意識(shí)地去記它，你走到電話(huà)前就能撥出那個(gè)號(hào)碼，”波德瑞克解釋說(shuō)。
Memorizing is a lot more useful, he pointed out. "If you use the habit system, you have to be at a phone to recreate the movements."他指出（敘述式學(xué)習(xí)方式的）記憶要有用得多，“如果你使用習(xí)慣性學(xué)習(xí)方法，你就得到電話(huà)機(jī)旁去重現(xiàn)場(chǎng)景。”
The problem, Poldrack said, is that the two types of learning seem to be competing with each other, and when someone is distracted, habit learning seems to take over from declarative learning.波德瑞克說(shuō)問(wèn)題就在于這兩種學(xué)習(xí)方法似乎會(huì)彼此抗衡，當(dāng)一個(gè)人分心時(shí)，習(xí)慣式學(xué)習(xí)方式似乎會(huì)取代敘述式學(xué)習(xí)方式。
