Study: participants had to learn to identify the letters of a language they did not know. The learning was prompted in one of three ways: writing by hand, typing, or watching videos.
“At the end, after as many as six sessions, everyone could recognize the letters and made few mistakes when tested. But the writing group reached this level of proficiency faster than the other groups—a few of them in just two sessions.”
Researchers also wanted to know if and when the three groups could generalize this new knowledge: spell like a pro, write words, spell new words, etc.
“The writing group was better—decisively—in all of those things.
“The main lesson is that even though they were all good at recognizing letters, the writing training was the best at every other measure. And they required less time to get there.”
