A neuroscientific study from the University of Tokyo in Japan shows that the human brain shows significantly different activity patterns when reading paper books and reading on electronic screens. Among them, paper reading may have an advantage in understanding complex narrative information.The research team recruited 25 young subjects and asked them to read the same comic story on two different media, and then monitored their brain activity through magnetic resonance imaging (MRI), while examining their understanding and memory performance of the story content. Each subject read both on paper and on a tablet device, serving as their own control group in order to more directly compare the effects of different media on the same person.
In the experiment, participants read a special comic that unfolded from the perspective of two protagonists, and the story was divided into two parts. After reading, the researchers asked the subjects both simple plot recall and complex questions that required integrating two narrative threads to examine their grasp of the overall context of the story.
The comic content is provided in paper version and e-reader form respectively. When the subjects answered the questions, the research team used magnetic resonance imaging equipment to focus on monitoring the activity intensity and distribution of specific brain areas. Because the MRI equipment is in a strong magnetic field environment, the researchers could not bring the tablet directly into the scanning room, so they arranged for the subjects to first read the first half of the story on paper or tablet outside the scanning room, and then read the second half through a head-mounted LCD display device during the scanning process.
The results showed that there was no significant difference in the accuracy of the subjects' answers between paper and electronic conditions, but the reading order and media combination had a significant impact on the speed of answering questions. Participants who read the beginning of the story on a tablet and then the second half on paper took longer to answer complex questions that required integrating the entire plot.
More importantly, the brain imaging results revealed differences in the "force mode" of different reading media in activating language-related areas of the brain. Participants who first read the story on paper showed lower activation in the language-related brain areas of the frontal lobe when they later understood the plot. The research team believes that this may mean that paper reading helps the brain organize narrative details with a lower "load" during the initial input stage of information, thereby reducing the cognitive cost of subsequent processing.
This study is called by the author to be the first to clearly reveal the specific differences in brain activity patterns between paper and screen reading from a neuroscientific perspective, although the experimental design is quite complex. The person in charge of the study pointed out that one advantage of choosing comics as a material is that its rich visual narrative elements can help subjects construct scenes and form a coherent story picture in their minds. This is the basic commonality with the plot structure of written narratives such as novels, making the results have certain extrapolation value.
However, the research team also emphasized the limitations of this study: the sample size was small, the participants were mainly young people in their 20s, and the reading materials were limited to the specific genre of comics. It is worth noting that this age group is the main group of e-book consumers in markets such as the United States, which provides a practical reference for future extended research on larger samples, wider media and text types.
It's difficult to draw absolute conclusions from this study about the relative merits of paper versus electronic reading, but it raises several scientific questions worth pursuing further. For example, whether paper books better match the brain's working methods in information integration and episodic memory through a reading experience with a more spatial sense and tactile feedback, thereby showing potential advantages in complex story understanding.
The research team has begun to conduct follow-up experiments, trying to use similar methods to compare the differences in brain activity and cognitive effects between "handwriting" and "keyboard typing", which is regarded as a natural extension of the comparative study of paper and electronic devices. The neuroscientist in charge of the project pointed out that the advantages of paper may not only be reflected in memory, attention and emotional investment, but also closely related to the language and thinking process itself, because paper reading is often accompanied by a more detailed reading and thinking rhythm.
Relevant results have been published in the academic journal "PLOS One", and the University of Tokyo also issued a press release to introduce it. As the migration of reading from paper to screen becomes more and more common, this kind of research that examines the differences in reading media from the perspective of brain science may become an important reference in the fields of education, publishing and digital content design in the future.
