Many college students have given up taking class notes by hand. Instead, they type on laptop or tablet computers. But scientists from Princeton University and the University of California say that that method is less effective.
If you need to remember something, write it. Writing notes by hand is much better for long-term memory of ideas, or conceptual information. That is the finding of a 2014 study published in the journal Psychological Science.
Unplug for a deeper understanding.
So, turn off your computer if you want to remember something. Computers can take your attention away from your work. They can be distracting. Computers provide the chance to send a quick message to a friend, check a sports' score, shop or watch a funny cat video.
It is really hard to resist a funny cat video.
But scientists say computers may hurt performance in school, called academic performance.
Here is what the research showed.
Students who type notes on a keyboard often transcribe, or write down what the professor says word-for-word. They may write without really thinking about what they are writing. These electronic notes contained more words. But scientists say it leads to "mindless transcription." Transcription means to record something exactly as you hear it.
However, students taking notes long-hand, or by writing them, need to first process the information they hear. Then they record just the main points, or summarize. They use fewer words. This is because people usually write slower than they type. This process of summarizing information leads to a deeper understanding, say the researchers.
In the study, students listened to a teacher and then took a test. Some took notes by typing on a computer. The others took notes by writing them down.
Both groups performed about the same in remembering facts. But students who typed their notes did much worse on conceptual questions. These questions required them to understand an idea.
Those who typed also could not stop transcribing even after they were told to try to avoid it. So even if you want to stop typing what you hear word-for-word, you might not be able to.
Also, researchers found that those who wrote their notes remembered conceptual information better a week later. Researchers believe that the students who wrote notes long-hand had a deeper understanding of ideas and concepts.
Hands off my computer.
Scientists know that students probably will still use their laptops and tablets in class. But they suggest using some of the available technologies for writing notes by hand on computer screens. They say this might be a good compromise between old school and new school.
This research was contained in a classroom. But the findings may be valuable for anyone wanting to remember more of what they read, hear or see.

所以，如果你想记住什么东西，关掉电脑吧。电脑能转移你在工作中的注意力，会分心的 。电脑让人给朋友发送即时信息，查看体育比分，购物或观看猫咪有趣的视频 。
然而学生们手写记笔记时，会先处理所听到的信息。然后只记下要点，或做总结 。他们写下的字数更少，这是因为人们通常写字速度慢于打字速度 。研究者说这种总结信息的过程会导致深层思考 。
