双眼皮有几种做法If you have ever tried a new sport or attempted learning a musical instrument, you are well aware that the hardest part is getting started. Once you figure out the technique, the skills return fairly easily, even if they are not ud for long periods of time. Most experts attribute this to “muscle memory”, which means the brain remembers the action and can recall it when needed. Now some rearchers from John Hopkins University believe there is another factor that may be as important in recalling previously learned motor skills—the errors made while learning the task.

自动化英语The study led by Reza Shadmehr, Professor of Biomedical Engineering, involved asking volunteers to play a simple video game: hitting a red target dot with a slightly smaller blue dot, similar to playing virtual games. What the gamers did not know was that as soon as the

What the scientists obrved was that though the volunteers did make mistakes every time the game was changed, they got successively faster at mastering it.
Shadmehr believes that this has something to do with the fact that in addition to delivering the task to muscle memory, the brain is also recognizing each wrong move and learning how to correct it. He compares it to having a coach that points out the mistakes and makes suggestions on how to improve.
What surpris the scientists most is that making mistakes not only trains the brain to perform better at a specific task, but also helps it learn faster from errors, even when the mistakes are made while learning a completely different task. The rearchers believe that the brain keeps a general databa of errors and draws_on them whenever a new motor skill is being learned, to ensure that mistakes are not repeated. This helps make successive learning process much faster.

I was appreciating my family photos on my computer, admiring my two beautiful babies, when I found a disturbing trend: my laptop was open in almost all the pictures. There was my daughter, 8 months old, playing at my feet while I was typing away on the couch. There was me and my son, with the laptop at my side as I held him in my arms.

I'd heard about the Internet addiction before, but always assumed it was something limited to socially challenged guys who played too much World of Warcraft (a computer game). Now it emed my Internet “habit” is slowly but surely crossing the line. Sometimes I find mylf up at midnight, surfing the Web while my family are sleeping. I read news, keep up with friends and write just for something to do.
It turns out that I'm not the only mama who is addicted to the computer. The moms are contributing to a growing global addiction. There's a movement among psychiatrists (doctors who specialize in mental dias) to recognize the Internet addiction as an official mental disorder. And a recent Stanford University national survey found that 14 percent of Internet urs find it hard to stay away from it for veral days at a time; 9 percent try to hide their “unnecessary Internet u” from their loved ones; 8 percent admit they u the Web as a way to escape problems.
You're likely not the kind of addict who doesn't bathe and abus drugs to help her stay “up” for more online time. You may have noticed, though, that going online has become a necessary part of your life, which, at least, means a load of clothes go unwashed. It may also mean you're missing much time with your baby—something you probably do care about.
