Paper Manga Reduces Brain Load vs Tablet, Study Finds

6/13/2026

Summary

Paper Reduces Load

Professor Kuniyoshi L. Sakai reported in PLOS ONE that 25 Japanese students read a manga on paper or on a tablet of equal size.
After reading, they completed recall and integration tasks in an MRI scanner, showing equal accuracy but slower tablet responses and higher activation in left frontal language, right frontal support and right angular gyrus.
Researchers concluded that paper’s sensory anchors lower mental workload during narrative integration.

Summary

Sakai Defends Manga

Researchers say the study’s focus on visual narratives may not directly translate to plain-text novels, limiting broader applicability.
Researcher Sakai argues that conventional texts would likely produce similar brain activation patterns because narrative flow and contextual integration are comparable across formats.
He notes that manga’s rich pictorial information aids scene comprehension, suggesting the visual element may have amplified the cognitive benefits of paper reading.

Summary

Tablet Increases Load

Tablet reading required more cognitive effort and longer time than paper reading.
Tablets use a backlight while paper relies on reflected room light, a visual difference that may affect processing.
Turning a page takes a fraction of a second longer than tapping a screen, subtly changing rhythm.
Authors warn that despite identical accuracy scores, some may interpret the findings as proof that digital reading impedes learning.

Summary

Sakai Compares Writing

Researchers will compare pen writing versus keyboard typing as a follow-up to manga study.
The study, authored by Keita Umejima, Yuki Sunada and senior researcher Kuniyoshi L. Sakai, is titled “Manga reading on paper vs. digital devices: Prospective effects on core and supportive integration processes in the brain,” emphasizing neural integration.
Kuniyoshi L. Sakai called pen-vs-keyboard study a natural next step and said future research will explore drawing or note-taking.
