Final answer:
The inability to remember personal experiences from early childhood is known as 'childhood amnesia'. Memory is fragile, and phenomena like encoding failure and memory transience play roles in such forms of forgetfulness. Childhood amnesia indicates complex interactions within our brain related to memory storage
Step-by-step explanation:
The inability of most people to remember personal experience from the first few years of their lives is technically called infantile amnesia.
Infantile amnesia is the phenomenon where adults have difficulty recalling events that occurred during their early childhood, typically before the age of 3 or 4. This lack of memory has been attributed to the immaturity of the brain during infancy and the limited development of language skills and concepts at that age.
For example, a person may not be able to remember their first birthday or their early interactions with their parents, even though they may have vivid memories from later childhood. This is a common experience shared by most people and is not considered a memory disorder or amnesia.
