What’s Lost as Handwriting Fades

Does handwriting matter?
Not very much, according to many
educators. The Common Core standards, which have been adopted in most states,
call for teaching legible writing, but only in kindergarten and first grade.
After that, the emphasis quickly shifts to proficiency on the keyboard.
But psychologists and
neuroscientists say it is far too soon to declare handwriting a relic of the
past. New evidence suggests that the links between handwriting and broader
educational development run deep.
Children not only learn to read more
quickly when they first learn to write by hand, but they also remain better
able to generate ideas and retain information. In other words, it’s not just
what we write that matters — but how.
“When we write, a unique neural
circuit is automatically activated,” said Stanislas Dehaene, a psychologist at the Collège de France in Paris. “There
is a core recognition of the gesture in the written word, a sort of recognition
by mental simulation in your brain.
Handwriting is being dropped in
public schools — that could be bad for young minds. Google’s new hands-free computer
is finding its way into operating rooms. Breast cancer survivors find the start
of their new lives in a tattoo artist’s work.

“And it seems that this circuit is
contributing in unique ways we didn’t realize,” he continued. “Learning is made
easier.”
A 2012 study
led by Karin James, a psychologist at Indiana University,
lent support to that view. Children who had not yet learned to read and write
were presented with a letter or a shape on an index card and asked to reproduce
it in one of three ways: trace the image on a page with a dotted outline, draw
it on a blank white sheet, or type it on a computer. They were then placed in a
brain scanner and shown the image again.
The researchers found that the
initial duplication process mattered a great deal. When children had drawn a
letter freehand, they exhibited increased activity in three areas of the brain
that are activated in adults when they read and write: the left fusiform gyrus,
the inferior frontal gyrus and the posterior parietal cortex.
By contrast, children who typed or
traced the letter or shape showed no such effect. The activation was
significantly weaker.
Dr. James
attributes the differences to the messiness inherent in free-form handwriting:
Not only must we first plan and execute the action in a way that is not
required when we have a traceable outline, but we are also likely to produce a
result that is highly variable.

That variability may itself be a
learning tool. “When a kid produces a messy letter,” Dr. James said, “that
might help him learn it.”
Our brain must understand that each
possible iteration of, say, an “a” is the same, no matter how we see it
written. Being able to decipher the messiness of each “a” may be more helpful
in establishing that eventual representation than seeing the same result
repeatedly.
“This is one of the first
demonstrations of the brain being changed because of that practice,” Dr. James
said.
In another study, Dr. James is
comparing children who physically form letters with those who only watch others
doing it. Her observations suggest that it is only the actual effort that
engages the brain’s motor pathways and delivers the learning benefits of
handwriting.
The effect
goes well beyond letter recognition. In a study that followed
children in grades two through five, Virginia Berninger, a psychologist at the University of
Washington, demonstrated that printing, cursive writing, and typing on a
keyboard are all associated with distinct and separate brain patterns — and each results
in a distinct end product. When the children composed text by hand, they not
only consistently produced more words more quickly than they did on a keyboard,
but expressed more ideas. And brain imaging in the
oldest subjects suggested that the connection between writing and idea
generation went even further. When these children were asked to come up with
ideas for a composition, the ones with better handwriting exhibited greater
neural activation in areas associated with working memory — and increased
overall activation in the reading and writing networks.

brain, which didn’t happen when they traced or typed the letter. Credit Karin
