St. John \ ‘s, Canada, Most people are not able to recall childhood memories especially during infancy. Not because it has not been able to remember, but because at a certain age the brain has ‘re-format‘ so that previous memories erased.
As an experienced computer hard disk reformat, the data in human memory can be lost at a certain age. That is why, nearly all adults are not able to recall memories that happened while still under the age of 3 years.
Originally it was thought that the new long-term memory is formed at the age of 3-5 years, so that previous events were not recorded properly. At that age who work only a short-term memory is needed in the learning process.
However, recent research conducted by Prof. Carole Peterson of Memorial University of Newfoundland break that notion. According to this study, the memory has been formed since the baby but the memories in it can be removed at the age of 4-7 years and then replaced with a new memory.
In that study, Prof. Peterson interviewed 140 children aged 4-13 years who were divided into 2 groups, namely the age of 4-7 years and 7-13 years. All participants were interviewed 2 times, each given a fairly long pause, which was 2 years old.
Interviews are conducted to explore the old memories that can be remembered by children. 2-year lag time that is given aiming for results can be compared, if there are changes in the child’s memory over time.
In the group 7-13 years, most long memories can remember 2 times in the interview did not change. In the first interview and second, the average participant in the age group was only able to recall memories that happened at around the age of 3-5 years.
But in the age group 4-7 years, the first and second interviews are generally subject to change. Most of the memories that conveyed in the first interview was denied by the participants in the interview the next 2 years, saying it could not remember those memories.
“Memory longest in young children is always changing, but at a certain age will recall that experience crystallization and after that will not change again,” said Prof. Peterson, as quoted by WebMD, Friday (13/05/2011).
