     With large and small keyboards everywhere, neither children nor adults need to write much of

anything by hand.That's a big problem.Study after study suggests that handwriting is important for brain

development-helping kids get fine motor skills and learn to express and create ideas.Yet the time devoted

to teaching penmanship (书法) in most schools has shrunk to just one hour a week.Is it time to give up

handwriting? Have a look at the link between the brain and penmanship, and you may get the answer.

    A test among students in grades 2, 4 and 6 found that they not only wrote faster by hand than by

keyboard, but also created more ideas when composing essays with handwriting.And other research

shows that the finger movements required to write by hand activate brain areas involved with thought,

language, and shortterm memory.

  A recent Indiana University study had one group of children practice writing letters by hand while a

second group just looked at those letters.Then, both groups of kids entered a functional MRI (核磁共

振) that scanned their brains as the researchers showed them the same letters.Researchers found that the

brain activity in the first group was far more advanced and "adultlike".

  Handwriting also affects other people's way they think of adults and children.Several studies have shown

that the same average essay will score much higher if written with good penmanship and much lower if

written out in poor handwriting.These studies have also found that people judge the quality of a person's

ideas based on his or her handwriting.And the consequences are real: On standardized tests with

handwritten sections, like the SAT, all essay that is considered hard to recognize gets a big zero.

    Studies show that this isn't only an Englishlanguage phenomenon.Chinese and Japanese youths are

suffering from "character amnesia". They can't remember how to write characters, thanks to computers

and text messaging.Some experts fear that Chinese writing and reading are so closely linked in the brain

that China's reading ability as a nation could suffer.
