Writing on paper triggers more brain activity than using a tablet or smartphone

TOKYO, Japan — As digital devices become an everyday part of society, many probably view a pen and paper as things of the past. Despite the ease of tapping information into a smartphone or tablet, a new study finds you may want to keep those paper notebooks after all. Researchers in Tokyo have discovered that people writing notes by hand display more brain activity than their peers entering data into an electronic device.

A team from the University of Tokyo adds the unique and tactile information that comes from writing things on paper may also help writers remember the information better.

“Actually, paper is more advanced and useful compared to electronic documents because paper contains more one-of-a-kind information for stronger memory recall,” says corresponding author and neuroscientist Professor Kuniyoshi L. Sakai in a university release.

“Our take-home message is to use paper notebooks for information we need to learn or memorize.”

The pen is mightier than the tablet?

It’s a common belief that digital devices help people complete tasks faster. Despite this, the study finds people writing notes by hand actually finished their task 25 percent quicker than tablet users.

Researchers add that paper notebooks also contain more complex spatial information than a digital screen. Physical paper allows the writer to add tangible permanence to their important information. Writers can also use irregular strokes to convey special meaning and uneven shapes — like a folded corner of a page. Study authors say “digital paper” is much more uniform. There is no fixed position when scrolling and the information disappears from view when users close the app.

What happens to the brain when you write on paper?

The study gathered 48 volunteers to read a fictional conversation between two people talking about their future plans. The discussion included 14 different class times, assignment due dates, and scheduled appointments. Researchers also sorted the participants — all between 18 and 29 years-old from university campuses or the NTT Data Institute of Management Consulting — into three groups, according to memory skills, personal preferences of digital or paper methods, gender, and age.

The groups then recorded the fictional schedules using a paper notebook and pen, a calendar app using a tablet and stylus, or an app on a smartphone using the touch-screen keyboard. The participants did not take extra time to memorize the information after completing the task.

After a one-hour break and an “interference task” to distract the volunteers from thinking about their notes, researchers gave participants a test on the conversation. The multiple choice questions also ranged in difficultly from simple to more complex. Simple questions asked “when is the assignment due?” while others included “which is the earlier due date for the assignments?”

During this test, study authors examined brain activity using functional MRI (fMRI) scans. During this procedure, scientists say increased blood flow in specific brain regions is a sign of higher neuronal activity.

The results reveal young adults using paper completed their note-taking in just 11 minutes. Tablet and smartphone users finished in 14 and 16 minutes, respectively. Volunteers using pen and paper also scored higher on the multiple choice test. However, researchers say the participants’ brain activity reveals even greater differences.

Volunteers using paper displayed more brain activity in areas with a connection to language and imaginary visualization. They also show more activity in the hippocampus, a brain region vital to memory and navigation.

Writing on paper may also be better for kids and creativity

Study authors say the fact that writing on paper triggers activity in the hippocampus shows analog methods contain richer spatial details which make hand-written notes easier to remember.

Digital tools have uniform scrolling up and down and standardized arrangement of text and picture size, like on a webpage. But if you remember a physical textbook printed on paper, you can close your eyes and visualize the photo one-third of the way down on the left-side page, as well as the notes you added in the bottom margin,” Sakai explains.

The team notes that it is possible to personalize digital documents, using highlighting, underlining, circling, and drawing arrows. People who prefer a digital pad can even leave virtual sticky notes that mimic analog-style spatial enrichment.

Although the experiment only included young adults, researchers believe the link between paper writing and brain activity will be even stronger in children.

“High school students’ brains are still developing and are so much more sensitive than adult brains,” Sakai adds.

“It is reasonable that one’s creativity will likely become more fruitful if prior knowledge is stored with stronger learning and more precisely retrieved from memory. For art, composing music, or other creative works, I would emphasize the use of paper instead of digital methods.”

The study appears in the journal Frontiers in Behavioral Neuroscience.
