Writing by hand may increase brain connectivity more than typing
According to a small study that monitored the brain activity of university students, writing by hand may increase brain connectivity more than typing.
Typing may be faster than writing by hand, but it’s less stimulating for the brain, according to research published Friday in the journal Frontiers in Psychology.
After recording the brain activity of 36 university students, researchers at the Norwegian University of Science and Technology determined that handwriting might improve learning and memory.
At the start of the experiment, the students were told to either write words in cursive using a digital pen on a touchscreen, or to type the same words using a keyboard. When a word such as “forest” or “hedgehog” appeared on a screen in front of them, they had 25 seconds to write or type it over and over.
Meanwhile, a cap of sensors on their head measured their brain waves. The cap’s 256 electrodes attached to the scalp and recorded the electrical signals of the students’ brains, including where brain cells were active and how parts of the brain communicated with each other.
“Our main finding was that handwriting activates almost the whole brain as compared to typewriting, which hardly activates the brain as such. The brain is not challenged very much when it’s pressing keys on a keyboard as opposed to when it’s forming those letters by hand,” said Audrey van der Meer, the study’s co-author and a neuropsychology professor at NTNU.
