Why do some people become face blind? Is face blindness a psychological effect?

The prosopagnosia ratio is 2.5, which is actually not low.

Patients with prosopagnosia have defects in the development of the fusiform gyrus and adjacent areas of the brain responsible for facial recognition, so they are unable to recognize faces as a whole like ordinary people.

This type of patient can only distinguish different people with the help of prominent features. For example, A has a big chin, B has a strange hairstyle, C has unique clothes, D has a sexy walking posture, etc.

Most cases of face blindness are congenitally inherited, and people with face blindness often have relatives who are face blind. However, some patients with prosopagnosia are not only unable to distinguish different faces, but also the faces of their own relatives.

It is not a psychological effect, but a natural physiological phenomenon.

I am also face-blind. It is not a psychological effect, but I really can’t tell the difference. I am very distressed, but my memory is also very poor after postpartum depression, so when I meet outsiders, I only like to smile and don’t like to talk. . I have a shop at home, and I never talk to customers in depth because I can’t remember her, and sometimes I can’t tell who is who. It would be bad to ask the same question next time we meet. Especially older aunts like to wear instant noodle hairstyles, which is really distressing for me.

I have a very slight face blindness. In many situations, I dare not take the initiative to say hello to people. I am always worried about recognizing the wrong person. But if you communicate with me for a few dozen seconds, I will immediately react: Oh, we just met [face covering]

My former colleague also told me that she has face blindness, but this does not affect Her job, on the contrary, is to deal with all kinds of people, and she does it extremely well.

Latest research has found that prosopagnosia, which was thought to be extremely rare in the past, is actually relatively common around the world. (The above explanation of face blindness comes from the Internet)

I think everyone is overly worried, mainly because they don’t really understand face blindness. If we are worried that we can’t recognize it, we can identify different faces based on the characteristics of each person. people. For example: her character, voice, way of speaking, etc. And if we perform intensive training on memory, then there should not be much difference between us and normal people.

Prosopagnosia is not a psychological effect, it should be regarded as a partial defect in the brain.

I am a person with prosopagnosia. I don’t recognize people by their faces, but by other characteristics of their bodies.

For example, the height, shortness, fatness and thinness of the body, the walking posture, such as hairstyle, clothes, bags, shoes, such as the tone of voice and tone of speaking, etc.

Only people who are very close to you can remember faces, and basically no one else can remember faces.

Once I went back to my parents’ house. I grew up there and many people knew me. As soon as I got off the bus, a woman about my age called out my name and asked me to go home. See your parents? I kept my smile on my face and agreed verbally, while my mind was spinning rapidly: Who is this person? …

After a few words of greeting, we nodded goodbye and went back to our respective homes to find our respective mothers. When we broke up, I didn’t remember who she was... [face covering]

This kind of I have encountered too many situations in the past few decades, and they happen all the time. Even when my colleagues are away on business for a long time, I will forget that face. I used to be a little distressed and anxious, but later I got used to it and can't remember it. , Forget it if you can’t remember, I love so and so.

Gradually, many people around me came to know about my problem and stopped making things difficult for me. They would take the initiative to greet me.

What I have to say is that I still offended a lot of people. They thought I was arrogant and didn’t even say hello when they met...

Even though I was wronged, there was nowhere to complain. [Crying out][Crying out]

Prosopagnosia is also known as "face amnesia". This symptom is generally divided into two types: the patient cannot see other people's faces clearly; the patient loses the ability to recognize other people's faces.

Patients with "prosopagnosia" do not have poor memory. They can remember names, phone numbers, and even books they have read. But what is confusing is that they cannot remember other people's faces, or even the faces in the mirror. For example, Sellers often looks at herself in the mirror, but she just can't remember what she looks like. Scientists believe that a single defective gene may cause "face blindness" and enable it to be passed on to future generations. Until recently, this particular form of prosopagnosia was thought to be extremely rare, with only about 100 cases documented worldwide, mostly caused by trauma, stroke or brain disease.

There are many in the brain. All parts are involved in processing information about facial images, but imaging studies have shown that a part called the fusiform gyrus face area is particularly important. This is the temporal lobe of the brain

In the 20th century In the 1940s, at the Wenondale Sanatorium near Stuttgart, Germany, neurologist Joachim Bodamer examined two patients with severe head injuries during World War II and proposed that short circuits could selectively exist in the brain. of facial recognition systems. Bodamer noticed that although patients could see faces, they could not recognize them, eventually concluding that seeing and recognizing faces represented two different brain functions. In his 2001 paper, Bodamer coined the word "prosop-agnosia", which is composed of the Greek words "prosopon" (face) and agnosia (meaning not to recognize or not know).

Over the next many years, doctors observed this phenomenon in stroke patients and other patients with neurological diseases, particularly those with damage to the tissue between the occipital and temporal lobes. However, it was not until 1976 that congenital prosopagnosia appeared in the medical literature: a girl only recognized her classmates' voices and clothes after a month or two, and then only about ten over the next 25 years. Several cases have been reported.

There are many wonders in the world. Why do some people become face blind? Why is it me? It’s not like I am face blind. , give me the whole road blindness. Is face blindness plus road blindness a psychological effect? ??It is really not a psychological effect. In fact, people like us put in much more effort than normal people. Let me tell you. I can remember it if we meet every day or once a month even if we don’t say hello, but if we only meet once every six months, even if we had a very hit-or-miss relationship the last time we met, we would chat for two hours. But we haven’t seen each other for half a year, and I have no memory at all. The most classic case is that my daughter has two parent-teacher meetings every year for three years in high school. My daughter and her deskmate are still best friends to this day. I have not met my daughter’s deskmate’s father for three years. We met at least six times. I also traveled to Hangzhou with his wife and children for five days. I actually didn’t get to know my daughter’s best friend’s father every six months. The key is that we held parent-teacher conferences and kept communicating and chatting very happily. Hi. When the meeting was over, we would walk and chat until we said goodbye to each other at the school gate. Other parents thought our families were family friends, but when we turned around and sat at the same table half a year later, I didn’t recognize him again, and then he I took the initiative to introduce myself, and then I remembered it with an oh, and did it again and again six times. Fortunately, I asked my daughter to tell my best friend, otherwise my best friend’s father would think that I was alone. Let’s talk about the blind road, in front of my house. I have sat on the carousel and rotated it for ten years. As long as it rotates, no matter how hard I try to separate my hair, I still don’t know where to go. There is also the bank in front of my house. Every time I go in and do something, I come out. You have to wait at the gate for a while, and your brain is trying to search which way is which, and then you dare to decide which way to go. This has been like this for more than 20 years, so a self-reliant woman like me doesn't dare to learn. drive.

Face blindness is not a psychological effect. True prosopagnosia is a disease.

A simple Chinese name for this disease is "face blindness".

It is due to congenital inheritance or acquired accidental injury, which causes functional damage to a certain part of the brain, resulting in the patient being unable to recognize and distinguish faces.

Severe people can reach this level -

The reason why we emphasize "real" face blindness is because there is another kind of face blindness that we think of. What we think of as face blindness is not a real inability to recognize faces, but just a normal form of forgetfulness.

This kind of forgetfulness has nothing to do with psychological effects.

There is a common sense that can illustrate this point well.

We often hear people joking: "I think foreigners all look the same, and I can't tell who is who at the end of a movie..." If we attribute this to... If face blindness occurs, people over 90 will be face blind.

In fact, foreigners are the same.

Not only do we see foreigners being confused, but throwing a foreigner into a crowd of Chinese people will keep the foreigners busy for a while.

Let’s talk about another common sense.

"Oh, I look familiar, but I can't remember it..."

"When I walked over face to face, he didn't even call me or say hello..." .."

Don't worry, don't blame yourself. Everyone has a lot of things in their mind, and they are all in a mess. His own affairs alone are enough for him to worry about. How can he keep an eye on the people he meets on the street one by one and be ready to pay greetings to his elders at any time?

Impossible. To sum up, it is normal for most people not to recognize others, so there is no need to make a fuss.

I am face-blind, but it’s not as severe as others have described, to the point where I forget about my face as soon as I meet him. Generally speaking, I will remember this person if I can meet him frequently in a short period of time. But if it takes a little longer, I won’t be able to remember it. The most typical example when I was in school was when I came home during the holidays. Most of the people in our village looked familiar to me. Some of them couldn’t remember whether they were from our village, and some couldn’t remember what they should be called. And I am one of the few college students in our village. People in the village will ask me to say hello when they meet from far away: "It's holiday? How is the food at school? Have you got a boyfriend?" etc., and I always ask I tried my best to answer and at the same time racked my brains to figure out who this person is who is talking to me [cover face] [cover face] That’s embarrassing, so I don’t think it has anything to do with psychology, it’s just that I can’t remember it, it’s not that I don’t want to Remember, after all, no one wants to be embarrassed.

The most embarrassing time was when I returned to my hometown in the third year of my marriage and bumped into my husband’s uncle. I actually forgot who he was, causing him to come to my house to ask me. Seeing that he didn't [cover his face]

I am face-blind, and sometimes others mistakenly think it is intentional, and I don't like to talk to others. Strangers will never be able to remember each other if they have not met several times. I often feel like I’ve seen someone somewhere before, and who is in the wrong position?

When I was opening my shop, one time, I met a man I had met several times. I know my husband very well. It happened to be that parking spaces were tight for guests staying at my hotel that day. This man parked his car in front of my store. I asked him to move the car. I really didn’t recognize him at that time. He was very angry and said that I did it on purpose and pretended not to know him. Later, my husband said that you didn’t recognize him anymore, wasn’t he Xiaoqiu? I just remembered that he also introduced guests to us. No wonder people are dissatisfied and I feel so embarrassed.

Another time, I was in front of the store and a woman greeted me. It seems familiar to me too, but I just can’t remember who she is. I kept thinking hard, and I always felt like this person had been in close contact with me. There is no such person among relatives, and there is no such person among friends. How on earth do we know him? Later I went to the bathhouse to take a bath and saw her again, and finally knew who she was. She gave me a bath and was a bath master. No wonder she had close contact with her [face covering].

I can’t tell myself whether it’s because of my heart or a problem with my brain, which prevents me from remembering people and routes. I just remember things very clearly.
