Why is it difficult for the memory of baby to remain?

ByDonnie Ray Jones

People who remember when they were born babies are a minority, and many people lose their memory before maturity. This is hard to memorize before 3 years old "Infantile amnesiaAlthough it is known as "the state is not known clearly. Old are called father of psychologySigmund FreudHas been studying from 100 years ago, BBC is summarizing research on childhood amnesia.

The baby 's brain absorbs new information like a sponge, and although 700 new neural communication paths are formed every second, it is not known why humans can not hold the initial memory, Research is currently being conducted at many research institutes.

The latest research suggests that baby consciousness and memory are starting training from the time they are in the womb of a mother, and it is not that we can not hold memories before 3 years old at all. By contrast, unless there is an effort to "remember" even adults, the stored information is lost with time. In other words, attempting to memorize is an important point, but in this respect German psychologist of the 19th centuryHermann EbbinghausIs conducting experiments to investigate the limits of human memory.

The experiment of Ebbinghaus is to store innumerable words called "meaningless syllables" made of random characters such as "kag" or "slans". We know that if we leave subjects who have learned meaningless syllables, we know that we will forget half of what we learned within an hour and the amount we can remember after 30 days is only 2 to 3%. It is said that it was made by this experiment "Oblivion curveThis chart shows that there is a certain pattern in forgetting human memory. Experiments comparing with this forgetting curve are considered effective for how the baby's memory is formed.

There are individual differences in the age at which childhood amnesia begins, there are people who "have memory of about 2 years of age", and in some cases, "I do not remember almost anything before age 7". It is said that the average value is 3.5 years old, and it is known that the country tends to differ from the age at which "first memory" appears. As Cornell University psychologist Qi Wang gathered hundreds of childhood memory experiences from Chinese and American college students, the memory of Americans was overcome longer than the Chinese and was remarkably subjective, It is said that the memory of the Chinese had a concise and realistic tendency.

Specifically, it is different from "I had a tiger at a zoo" than "I had a tiger when I went to the zoo, but I was scared but I enjoyed it very much", which is remembered by those who focused on self It is simple, so to speak, self-centered, shows the possibility of favoring the formation of memories of early childhood. According to Mr. Wang, memory in early childhood is not regarded as important in China, but it is indigenous in New ZealandMāoriHe has a culture that emphasizes the past, and many Maori people were able to speak on average about memories from about 2.5 years old.

The Māori survey shows that culture influences memory, and there are many psychologists who assert that acquisition of language ability will help to form memories. On the other hand, some psychologists are skeptical of the relationship between language ability and memory, and I also know that the early memory of children who can not hear is not special late. From this, BBC says that we can not hold memories of childhood, simply because "the hippocampus, which is the field responsible for the memory of the brain, has not been developed".

A patient famous for the history of neuroscience "HM"I could not memorize new things after the medial temporal lobe including the hippocampus was removed for epilepsy treatment, but the hippocampus when my baby was also undeveloped as well It is thought that memory is hard to settle for because of it.

However, it is also true that there is something that affects people in the form of trauma etc. since the experience of a baby became bigger, and it is not that people can not memorize any childhood experience. Memory-related researcher at St. John's University, Jeffrey Phargen said, "Baby's memory is probably stored in a different location from the hippocampus, which is an unresolved place at this stage and demonstrates its location It is very difficult to do.
