"Digital tools have uniform scrolling up and down and standardized arrangement of text and picture size, like on a webpage. Researchers say that the activation of the hippocampus indicates that analog methods contain richer spatial details that can be recalled and navigated in the mind's eye. Volunteers who used paper had more brain activity in areas associated with language, imaginary visualization, and in the hippocampus - an area known to be important for memory and navigation. However, researchers say that the brain activation data revealed significant differences. Volunteers who used analog methods scored better than other volunteers only on simple test questions. Volunteers who used analog methods in their personal life were just as slow at using the devices as volunteers who regularly use digital tools, so researchers are confident that the difference in speed was related to memorization or associated encoding in the brain, not just differences in the habitual use of the tools. Tablet users took 14 minutes and smartphone users took about 16 minutes. Participants who used a paper datebook filled in the calendar within about 11 minutes. This is a technique called functional MRI (fMRI), and increased blood flow observed in a specific region of the brain is a sign of increased neuronal activity in that area. While they completed the test, volunteers were inside a magnetic resonance imaging (MRI) scanner, which measures blood flow around the brain. There was no time limit and volunteers were asked to record the fictional events in the same way as they would for their real-life schedules, without spending extra time to memorize the schedule.Īfter one hour, including a break and an interference task to distract them from thinking about the calendar, volunteers answered a range of simple (When is the assignment due?) and complex (Which is the earlier due date for the assignments?) multiple choice questions to test their memory of the schedule. Volunteers then recorded the fictional schedule using a paper datebook and pen, a calendar app on a digital tablet and a stylus, or a calendar app on a large smartphone and a touch-screen keyboard. Researchers performed pre-test analyses to ensure that the volunteers, all 18-29 years old and recruited from university campuses or NTT offices, were equally sorted into three groups based on memory skills, personal preference for digital or analog methods, gender, age and other aspects. In the study, a total of 48 volunteers read a fictional conversation between characters discussing their plans for two months in the near future, including 14 different class times, assignment due dates and personal appointments. "Our take-home message is to use paper notebooks for information we need to learn or memorize," said Sakai. In contrast, digital paper is uniform, has no fixed position when scrolling, and disappears when you close the app.
Physical paper allows for tangible permanence, irregular strokes, and uneven shape, like folded corners. The research was completed with collaborators from the NTT Data Institute of Management Consulting.Ĭontrary to the popular belief that digital tools increase efficiency, volunteers who used paper completed the note-taking task about 25% faster than those who used digital tablets or smartphones.Īlthough volunteers wrote by hand both with pen and paper or stylus and digital tablet, researchers say paper notebooks contain more complex spatial information than digital paper.
