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.

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 http://static01.nyt.com/images/2014/06/03/science/03JPWRIT3/03JPWRIT3-articleLarge.jpgwith 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.
