Here’s Why We Can’t Remember Early Years of Growing Up

Many people have encountered the frustrating experience of attempting to recall memories from their toddler or infant years, only to be met with a hazy fog instead of clear recollections. This phenomenon, commonly known as infantile amnesia, is a common occurrence. But why does it happen?

Infantile amnesia is the inability of adults to remember events from their early childhood, typically before the age of three or four. Despite the numerous experiences and interactions during those formative years, most individuals retain very few, if any, memories from this period.

Unlike other forms of amnesia that result from brain injury or trauma, infantile amnesia occurs in neurologically healthy individuals. It specifically affects memories formed during early childhood. This distinction highlights the unique developmental aspects involved, such as incomplete brain maturation and limited language skills, contributing to the difficulty in recalling memories from infancy.

Brain development

One of the primary reasons behind infantile amnesia depends on the development of the brain during infancy and early childhood. The hippocampus, a brain region crucial for memory formation, undergoes rapid growth and maturation during these years. However, this development is not yet complete in infancy, which affects the encoding and storage of long-term memories.

Language development

Another factor contributing to infantile amnesia is the development of language skills. Language plays a vital role in how people remember events and experiences. As language skills improve with age, children become better equipped to encode and retrieve memories. The lack of developed language abilities in infancy may hinder the formation of coherent and retrievable memories.

Neural connections

During infancy and early childhood, the brain forms an abundance of neural connections. However, not all of these connections are maintained into adulthood. As the brain undergoes pruning -- a process where unnecessary connections are eliminated -- memories formed during infancy may be lost or inaccessible due to the restructuring of neural networks.
