Go Tokyo Your Experience
With the diversification of entertainment choices, but people’s time has not increased, more and more people are also focusing on efficiency when enjoying entertainment, choosing to watch movies, TV dramas, or online videos in a “fast track” way. This behavior has sparked a lot of controversy, for example, some people believe that it is disrespectful to creators or may damage their self-discipline.
A commonly discussed viewpoint is that fast forwarding makes it difficult to truly understand the content of a film. So, is that really the case? Let’s take a look at the research of a Japanese high school student together.
Experimental analysis of high school students shows that when watching videos accelerated to 1.75 times, there is no significant impact on comprehension level
At a recent national science exhibition for high school students held in Japan, the research report by third year student Susumu Ueno from Hiratsuka Jiangnan High School in Kanagawa Prefecture caused a huge uproar.
Her research topic is “The Impact of Fast Forward Watching on Understanding and How to Effectively Utilize It” (Methods for Utilizing the Efficiency of the Impact of Double Speed Watching on Understanding). This study focuses on the increasingly common behavior of “fast switching to watching movies” among young people, exploring whether fast switching to watching affects comprehension and how this method can be used to improve learning efficiency.
Since the summer of second grade, I have been researching this topic to understand the impact of fast switching to watching movies on comprehension ability. This is because I have noticed that more and more students tend to watch movies or educational videos on fast switching. I hope to use this research to help fellow students who are accustomed to fast switching to watching movies find more efficient learning methods
Ueno’s research method is to have multiple participants watch the same film at different acceleration ratios, and then test their understanding and memory of the film content through multiple-choice questions.
The experimental results show that:
I originally thought that ‘the faster the video playback speed, the greater the impact on understanding’, but the experimental results showed that when the video was turned to 1.75 times faster, it actually had no effect on understanding. After increasing the experiment, I found that the presence of subtitles significantly improved understanding scores. Therefore, the conclusion is that the presence of subtitles has a significant impact on understanding when watching videos at fast speed
In the future, I hope to further confirm the differences in this phenomenon across different disciplines, as well as the impact of repeated viewing on understanding, in order to explore the most effective learning methods
This research result quickly sparked heated discussions among Japanese netizens, with many sharing their experiences of adjusting the playback speed of videos in their daily lives.
I usually tune it to 1.75 times when watching YouTube
I usually set it to 1.7 times, so my intuition was quite accurate
Twice the speed is indeed too fast, 1.75 times is just right for it
1.75 times is my limit, and I usually set it to 2 times when searching for specific scenes in my watched works
When there are subtitles, I can increase the speed by 4 times… For videos with limited content, staring at the subtitles for 20 seconds is considered complete
When I want to watch slowly, I adjust it to 1.4 to 1.5 times, usually 1.6 times
Watching movies at a normal speed can actually distract you from thinking about other things, but doubling it can avoid distraction
When there are no subtitles, the maximum adjustment is 1.5 times, and when there are subtitles, it can be about 2 to 2.5 times
The definition of ‘level of understanding’ is difficult, does’ emotion ‘count
I am curious about the performance of different age groups in this regard
For middle-aged men, 1.75 times the speed is really difficult and they may forget what they have done
After getting used to 1.75 times, do you feel that even faster speeds than 1.75 times are acceptable
Does seeing such research results prompt you to consider adjusting your viewing style?
