Write it out by hand, give your brain a boost

The old art of handwriting has been found to improve mental activity, Gwendolyn Bounds reports in The Wall Street Journal.

During one study at Indiana University published this year, researchers invited children to man a "spaceship," actually an MRI machine using a specialized scan called "functional" MRI that spots neural activity in the brain. The kids were shown letters before and after receiving different letter-learning instruction. In children who had practiced printing by hand, the neural activity was far more enhanced and "adult-like" than in those who had simply looked at letters.

"It seems there is something really important about manually manipulating and drawing out two-dimensional things we see all the time," says Karin Harman James, assistant professor of psychology and neuroscience at Indiana University who led the study.

It's good for grown-ups, too.

Adults may benefit similarly when learning a new graphically different language, such as Mandarin, or symbol systems for mathematics, music and chemistry, Dr. James says. For instance, in a 2008 study in the Journal of Cognitive Neuroscience, adults were asked to distinguish between new characters and a mirror image of them after producing the characters using pen-and-paper writing and a computer keyboard. The result: For those writing by hand, there was stronger and longer-lasting recognition of the characters' proper orientation, suggesting that the specific movements memorized when learning how to write aided the visual identification of graphic shapes. 

Handwriting affects how we think and develop ideas.

Virginia Berninger, a professor of educational psychology at the University of Washington, says handwriting differs from typing because it requires executing sequential strokes to form a letter, whereas keyboarding involves selecting a whole letter by touching a key. She says pictures of the brain have illustrated that sequential finger movements activated massive regions involved in thinking, language and working memory—the system for temporarily storing and managing information.

Interesting thought as I type this post on a laptop.
