An example can be taken from education. Educationalists advocate allowing parents to take their children to cast a wide net to find points of interest.
For this reason, some parents take their children to learn various things in the hope of exploring their children's interests. As a result, they will find that even if their children show a strong interest in piano, after taking their children to practice piano, they will suddenly become
Like turns into dislike.
Do the brain's interests change?
From a medical point of view, going back to the most basic anatomy, anatomy has long told you that nerves will remodel, but it is difficult for nerve cells to grow again after they die, so there are many sequelae after brain damage. This shows that in a short period of time
It is impossible for the brain's points of interest to change back and forth.
The only reason that can explain the above phenomenon can only be: this interest is not that interest, and you have found the wrong interest.
Look at it this way, interest is so hard to find, and it will run away from you when you think you have found the result.
In fact, it is correct to cast a wide net in education, and it is also correct to observe the human body's emotional and other reactions to things to judge whether it is a point of interest. What is wrong is only the level of the observer.
To discover a person's interests, it is really difficult for ordinary people to do it at their intellectual level. Please refer to the purpose of many parents of students in pursuing good teachers.
Can a good teacher really understand the in-depth principles of discovering students' interests, that is, medical principles? Obviously not. This is why a teacher who claims to be a great teacher cannot make 100% of the students he teaches become all walks of life.
The academic master.
It can only be said that good teachers have fully understood some phenomena and encountered some luck.
Don't talk about teachers, doctors must have a thorough understanding of this medical principle, because if you understand the mystery, you will know that it is almost difficult to do.
The specific analysis is as follows. First, let’s clarify the definition of “interest” in medicine. As mentioned in the above experiment, it must be some kind of external stimulation that can increase brain function activity and thereby improve brain efficiency.
You can think of this external stimulus as a key to open sesame. Once you say it and do it, it opens the door to the brain treasure house of the human body. In other words, it connects the brain to a rare power source, making the brain instantly feel like it is loaded on a rocket.
The transportation capacity is running rapidly.
What a successful observer has to do is how to observe the key.
In medicine, we will first explore the person's previous experience, just like investigating the "medical history" to find out the past success history of this "patient", and find clues to the key. Finally, we will do verification to check whether this is the case.
Give the key.
Search again and again, sift again and again, and finally sift out a more accurate key.
The above is the process. When it comes to the specific steps, if you want to observe the key, you have to rely on the observer's eyes and brain to observe the reaction of the subject's brain to external stimuli.
For neurosurgeons, they can observe the coordination of a person's hands and feet, observe a person's emotional response to things, and even observe a person's eyeball movements, etc., and finally combine all reaction symptoms to make a comprehensive medical judgment.
The biggest difficulty here lies in the subtleties.
It is easy for doctors to see patients because the symptoms they exhibit are different from those of normal people.
What level of visual acuity does it take to observe normal details from a normal person?
Can instruments be used to replace the naked eye? Doesn’t it mean that fMRI scans can be used?
