The author watched the Popular Science to Variety Show "Refueling to the Future" broadcast by CCTV on July 31 these two days, which has an impressive content, that is, Fu Yandong's magic trick led to a fragment of the theory of blind vision, and after the author thought deeply about the copywriting of the program, he inexplicably got goosebumps. Next, the author will analyze the strength of a wave, what made the author so moved at that time.
Regarding the phenomenon of blindness, the author first analyzes its origin and definition for everyone.
In the 1950s, an 8-year-old child injured his brain in a road accident. His left hindbrain was damaged, especially the primary visual cortex. As a result, most of his right field of vision was lost. Years after the accident, his neurologist discovered something unusual. The child can still see the food on the right, although he is not fully aware of this phenomenon.
The neurologist had him face the screen and stare at a small fork in the middle of the screen to fix his eyes. A small dot appeared in an area he couldn't see, and the doctor asked him to point out where the dot was. The little boy was confused, and he thought there were no dots of light on the screen. But then he made a wayward guess and pointed out the location of the small dot impartially. After trying again and again, when small dots flash in different locations in areas he can't see, he can most of the time pinpoint the location of the small dots accurately.
This eccentric phenomenon is called blindsight. British scientists Larry Weiskrantz, Nicholas Humphrey and other researchers discovered the phenomenon in the 1970s. The cause of this phenomenon is damage to the primary visual cortex, a complex region of the brain used to capture visual signals. Without this area, certain levels of vision are still there but conscious visual experiences are gone.
But most of the blindness we mention in our daily lives refers to variable blindness.
Blindness to change is a phenomenon that people cannot observe instead of observing large changes that are usually easy to notice. When we are able to perceive, recognize, and locate changes that occur in the world around us, this is called change detection. However, there are many times when we are not aware of this change, a phenomenon called blindness of change. In simple terms, change blindness refers to the phenomenon that the observer cannot detect changes in an object or situation.
In 1998, Harvard University and Kent State University targeted passers-by at universities about how alert they were to the immediate environment. In the experiment, an actor walks up to a passerby and asks him for directions. When passers-by pointed the actor in the direction, two people passed between the actor and the passer-by with a large wooden door, completely blocking their view for a few seconds. During that time, the original actor will be replaced by another actor, not only their height and physique are different, but even their clothing, hairstyle and voice are different. More than half of the participants did not notice the replacement change.
This experiment was one of the first to elucidate the phenomenon of "changing visual blindness", and it simply showed us that we were very selectively receptive to the visual scenes that existed to be offered—which seemed to show that we depended more on our memory and pattern recognition than we thought.
In 1999, a Harvard professor conducted an experiment called "Vanishing Gorillas" and published a famous article to reveal the principles of blind vision. In layman's terms, the phenomenon of blindness refers to the fact that when we have a lot of changes in front of our eyes, we will only pay attention to some parts that are prominent, or parts that we are interested in, and if something is less prominent or we are not interested, we will not notice its change.
The most complex action in our daily lives is driving (driving a car), and when you are attracted by your mobile phone while driving, you will ignore the observation of the road ahead, which is very dangerous. Therefore, the reason why we advocate driving as much as possible not to use mobile phones and not to chat with people is more because attention will be distracted and the dangers in front of us cannot be found, resulting in accidents.
But as I said at the beginning, this passage about blindness gave me goosebumps at some point. Not fear, but emotion. This kind of emotion is how the author feels when he thinks of something deeper.
The last sentence of "the tree wants to be quiet and the wind is not stopping" must be a cruel reality that many people do not want to encounter in their lifetime. However, when we are busy with our lives every day, and we are camping for every minute and every second of trouble, we often forget the people, parents, lovers, and children that we ignore. We always strive to show the best side to outsiders, but show the worst side to those who love us, pay too much attention to our work, career, and achievements, so we lose patience and Wenzhou for our family and friends.
The city that has been living for a long time wants to leave after all, or will come back again, listen to the tired song deleted for a long time and finally downloaded back, people who have been separated for a long time, maybe one day suddenly meet again, anything is possible, but the only time can not go back, and can not come back.
So don't be blinded by the things in front of you, you have to see what you are facing in front of you, you also have to see the people around you, you have to see the difficulties and sufferings, but also to find happiness and happiness. Be a happy mortal who is mediocre and idle in life.
