Why are human memories lost before the age of 3, and are they really deliberately erased?

Each of us remembers what we did when we were younger, and we feel that our memories are fresh and memorable.

But strangely, we never seem to remember what happened before we were three years old. It can be said that although our intelligence was not high enough at that time, it was enough to understand the world around us. Why don't we have memories?

In fact, not only do we not have a way to explain the problem, but scientists are also confused. Psychologists have even invented a term specifically called childhood amnesia.

Everyone knows that both learning about the world and remembering things is done by the brain. Some scientists believe that our brains are not fully developed before the age of 3 and that the parts responsible for memory are the same. The most important part is the part called the hippocampus.

They believe that humans are not fully developed these parts before the age of 3, so they are unable to complete memory work, which leads to a lack of memory before the age of 3. The principle of memory formation is that synaptic connections are formed between neurons, and the deeper the memory, the stronger the synaptic connections, and those memories that are not used, the synaptic connections between them will be released, and the memories will begin to blur and disappear. This is also the reason why humans forget things, and the information you don't use for a long time will be deleted by the brain.

Differing views were also raised. Some experts say: in fact, before the age of 3, we will have the knowledge and memory of the world.

The problem, however, is that the way we remember before and after the age of 3 (not the exact 3 years of age, of course, which will vary from person to person) is inherently different. In adulthood, memories before the age of three are still stored in the brain in some form, but our new memory methods are no longer able to read them, so we behave as if we had no memories.

Like 20 years ago, people were still using floppy disks to store things. Although these things are still well preserved, today's computers no longer have floppy disk interfaces, so everyone doesn't know what's stored in them. In fact, this claim seems to be more reliable than the previous one, since there have been more than one instance that there are still special people in the world who can remember fragments of infancy. There are even some very special people who will bring them a lot of baby memories.

No, the main reason is that people's brain development before the age of three is not perfect, and the memory nerve cells are still not sound, so there is no memory of some things at all.

It's not deliberately erased, because the three-year-old baby has a memory but can't remember things, and has no memory of what happened to him.

Of course, it wasn't deliberately erased, but because I didn't remember much before I was 3 years old, and I think it's normal for this to happen at a young age.

Why do humans "lose" memories before the age of 3? Is there something in control? Due to insufficient brain volume, infants have limited ability to observe and remember.

If you were asked to take a test before the age of three, would you remember? How many can you think of? I think most people don't have a memory of things rising until they're three years old.

Even if they do, they may form a little impression in their brains after listening to someone else's description, but they rarely remember specific things. It is also possible that many people listen to other people's descriptions for so long that they form an image in their brains that gives the illusion that they still have a memory.

<> brain, as the highest part of the nervous system, is the command center of our body, mainly responsible for the functions of movement, sensation, language, emotion and execution, and is the material basis of all thinking activities. What we call observation, attention, memory, thinking, and imagining are all inseparable from the brain. So why don't most of us remember anything until we are three years old?

In fact, these are related to brain development and organization, let's understand it.

People often have difficulty recalling events early in their lives clearly, a phenomenon known as "childhood amnesia", which is often very vague when recalling experiences between the ages of 0 and 4. But in this case, people forget more episodic memories – that is, narrative memories about where and when events in their lives took place – than knowledge-based memories, like how to eat with a spoon or walk. The development of amnesia in children is related to the structural development of the brain, as well as the different neural regions of the brain.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you have any ideas, you can let us know in the comments below.

At this time, the Xiangye hippocampus in the brain is not fully developed, and does not have the ability to store it and nerve points, so before the age of 3, our brain is busy developing the nerves and tissues completely, and the hippocampus is also gradually growing, and after the age of 3, our hippocampus initially has this function. Therefore, before the age of 3, my brain does not have the concept of memory, so naturally it cannot store relevant memories.

We know that the weight of an adult's brain is about 1400 grams, while the weight of a child's brain before the age of three is only 350 grams to 400 grams, so humans will lose their memories before the age of three. By the age of three, children have learned the basic skills of talking, walking, and avoiding danger. The brain is an energy-consuming organ, and too many synaptic connections can exacerbate energy expenditure.

So the brain cleans itself up and clears out excess synaptic connections.

Precisely because we have no cognitive abilities before the age of three. In addition, memory is not fully developed. It's our system that's in control.

Here's a simple question for you: Do you remember memories from before you were 3 years old? I believe that few people can answer, and even if there is, it is only one or two fragmented scenes or words at most.

According to the survey, most people's memories before the age of 3 are almost blank, many people think that this is because the time is too long, the memory is blurred, but why the memory of adulthood is still clear in the mind even after thirty or forty years, but five or six-year-old children can not tell what happened three or four years ago. It can be seen that the lack of memories left in infancy and early childhood is not only due to the problem of age.

Studies have shown that 2-month-old babies can recognize things they saw 24 hours ago, while 1-year-old babies can recognize things a few days ago, and at the age of 3, they can even recall bits and pieces of things from 1 year ago. All in all, children generally do not retain memories for more than a year before the age of 3, and if the father comes home after a year of absence, the baby may treat him as a stranger. So why do humans lose their memories before the age of three?

Let's see what memory experts have to say!

Caroline Roy Collier, a memory expert, has shown that throughout a person's lifelong development, people will gradually lose their memory. And for babies, although their brains have a slower rate of information extraction and a less powerful amount of storage.

But they will remember certain deep memories(e.g. in case of danger and accidents)., and when they see a reminder related to their memory, their memory is reactivated. The more times a memory is retrieved, the longer that memory will be retained.

There are probably two reasons why most people can't recall the experience before the age of 3:

The consciousness before the age is not mature enough

Before the age of three, children are still in a period of growth and development, and especially in all aspects of organs such as the brain, are not fully developed. Since a memory system that is not fully developed does not leave any mark, it is likely that a three-year-old child has no memory because the brain is still developing.

Children before the age of 3 remember differently

The memory mode between children and adults before the age of 3 is different, as children continue to grow, their memory will also think about the memory mode of adults in the development to get closer, at this time there will be a process of choosing memory, and in scientific terms, it is to recall the memory of childhood after growing up, and can no longer read the memory coding before the age of three, but they still exist.

Even if we forget the memories we had before the age of 3, that's okay. Until one day, when the baby has grown into an adult and starts to take care of another baby, everything will be known.

Because the human brain has limited memory storage, the human brain needs to make room to store the later memories, so it will automatically reject the memories before the first three years of age.

Before the age of three, our minds are not yet mature, and even our memory functions are not fully developed. Unable to store memories.

Because the hippocampus and amygdala involved in memory during that period did not mature, permanent memories could not be formed.
