Why don t humans have memories before the age of three?

Why don't humans have memories before the age of three? First of all, the brain is not fully developed until the age of three, and the leaf forehead and hippocampus do not begin to grow until nine months of age.

As we grow older, many of our memories become blurry, but even if they are blurred, some fragments will be remembered, but the memory before the age of three seems to be gone, is the brain being manipulated?

Because before the age of three, the human brain is not fully developed and cannot store memories completely, so there is an illusion that the memory is lost and there is no memory before the age of three.

Because of immaturity. Before the age of three, some areas of the brain are not mature and do not have the ability to remember, and then the structure is complete.

Because brain development at that stage has just begun, there is no memory at all, so it is blank until the age of three. Even if there is a memory after the age of three, it is vague, and it can only be clear when the brain is fully developed.

Summary. Because people are still in early childhood until the age of three, their body organs and the nervous system that stores memories are in the developing stage. At this stage, their ability to perceive the outside world and their ability to organize language is relatively weak, and their understanding of things is a period of blind perception or initial ignorance.

Memories exist before the age of three, but most people can't remember the things they have experienced without cognitive awareness, which is like "throwing away".

Why don't people have memories before the age of three?

Because people are still in early childhood until the age of three, their body organs and the nervous system that stores memories are in the developing stage. At this stage, their ability to perceive the outside world and their ability to organize language is relatively weak, and their understanding of things is a period of blind perception or initial ignorance. Memories exist before the age of three, but most people can't remember the things they have experienced without cognitive awareness, which is like "throwing away".

As time increases, the previous memories become more and more blurry, which is also a process of losing memories!

Recall, do you remember what happened when you were one year old? Or do you remember what happened when you were three years old? Many times we will find that as we get older, our memory is not as good as day by day, even if it is something one minute, the next second may be forgotten.

Even if we have been trying to remember, we will find that the most we can remember is what happened in kindergarten, and then it seems to be a blank slate.

Everyone's memory is different, but the vast majority of people seem to have one thing in common, which is that the world seems to be a blank slate to us before the age of three. So why do we "lose" memories before the age of three?

Anyone who has children around you knows that even if you ask a two-year-old child what she did yesterday, she can know you, so children under the age of three have a memory, they know what they have done, and they have a certain understanding.

So for the question that most people can't remember before the age of three, the doctor explained that it's not that your memory really doesn't exist, it's just hidden. Because before the age of three, we record the things in our lives not by using language to remember, but more likely through feeling, touch, because the language system of three-year-old children is not very perfect, but when we grow up and recall, the language system is perfect. Therefore, the human brain develops the fastest at the age of three.

In addition, in the process of growing up, people have seen a bigger world and come into contact with more things, not only increasing the things in the brain, but also automatically correcting the previous wrong cognition, and it is not impossible for new memories to replace old ones, so our previous memories may just be replaced by new things.

Before the age of children, they are still in the stage of development, and the sensory system and language system have not yet matured, so they will not have too strong ability in memory, so they don't remember everything so clearly before the age of 3, or even forget everything. After the age of 3, you can remember things very clearly.

2. It is believed that human memory is not innate, but only acquired through learning. Just like when we talk and walk, we are not born with it, but we learn it slowly through the continuous teaching of our parents and family members. Different people have different teaching methods, and the effect of learning will be different.

3. The same is true of memory, which requires the cooperation of our sensory system and language system in order to maintain the formation of memory. If you don't have the cooperation between the two, then even if you can form a memory, it won't last long.

First of all, we will talk about the topic of "baby amnesia". This is also the concept of "childhood amnesia" proposed by Sigmund Freud, the father of psychology, 100 years ago: adults cannot extract the memory of situations and events before the age of 2-4, and with the passage of time, adults' memories before the age of 10 may be worse than imagined.

Everyone's first reaction must be to think for a long time, and then desperately search for memories related to it in their minds. We humans have evolved from the age of gorillas to people with the ability to think independently, and then from infancy to old age, in the long years in between, the fragments of events experienced by humans occupy our brains layer by layer. Except for some things that we remember deeply or habitually, which form a clear memory, other things have long been forgotten.

Secondly, let's talk about the topic of "whether there is memory before the age of three", which experts still cannot give a definite explanation after a lot of experimental research. Scientists have different views on this.

The first point of view: there are memories before the age of 3, but we can't remember clearly! With the passage of time, those memories are mostly forgotten, just as we forget every detail of the previous days, and the memories that came before are blank for us.

The second view: no memory before the age of 3. We need to recognize a new term – "hippocampus".

It is a substance that exists in our human brain and is specifically used to store memories. Before the age of three, infants and young children's brains are not fully developed, and the hippocampus, which is called a part-time body, is not yet mature, and the structure and function of the memory cortex cannot sustain long-term memory needs. That is to say, the things we have experienced cannot be stored in our brains in their entirety because of the memories they have experienced.

Before the age of three, people's brain development is not perfect, the development of thinking and memory function are not particularly strong, and the number of cells in the brain is relatively small.

People generally have no memory before the age of three, because the brain development is not very complete at this time, and it is normal to not remember the things when they were young.

The location of the hippocampus in the brain.

The neurons we have as children grow at a rapid rate. However, the hippocampus can only carry a certain number of neurons. So is it because new neurons replace old ones, so that we lose our memory?

Many scientists speculate that it is in this process of handover between the old and the new that our hippocampus will undergo a small range of circuit destruction and recombination, thus affecting personal memory. In other words, the rapid growth of nerves in infancy may be the cause of "childhood amnesia".

Because people's memory is limited, they can't store so many things, it's not a popularity bug, it's just the structure of people and the characteristics of people.

Because at that time, the brain was not fully developed and could not remember things; I don't think it's a human bug
