Fragmented Short Video Browsing is Harmful to the Brain, Tests Show Significantly Reduced Memory Accuracy
Short videos are changing people's lifestyles and subtly influencing how the brain works. Recently, on CCTV's "Full Explanation of Hard Science Technology" program, reporter Shuai Jun pointed out that a short video has barely begun when it's swiped away, with changing images, sounds, and emotions, the only constant being the upward swiping motion.
Seemingly immersed in a flood of information, it is actually difficult to leave a clear memory, like "carrying water in a bamboo basket," quickly emptied.
Recent scientific research shows that fragmented short video browsing is actually harmful to the brain and will slowly damage our reading and learning abilities.
Swiping away a short video after just a few seconds, with constantly changing images, causes the brain to switch frantically. It seems relaxing, but in fact, it's constantly "overtime."
Once the brain gets used to this fast, irregular switching rhythm, it becomes particularly difficult to concentrate on coherent content such as listening to lectures or reading books.
A research team from Central China Normal University conducted a related experiment: they prepared two video contents, each with a total duration of 10 minutes. One group was a complete documentary, and the other group split the same content into 7 short videos for subjects to watch one by one.
Scientists found that the former had an information memory accuracy rate of approximately 60%, while the latter only had approximately 40%.
The brain needs coherent and complete logic to form memories, while short videos are a pile of scattered fragments with no chronological order and no causal logic. You think you've learned a lot of knowledge, but in fact, your brain has been empty all along.
