It highlights the important influence of early life experiences on mental and emotional wellbeing later in life. In research in animals, scientists have found that latent traces of early experiences remain in the brain for a long time, and can later be triggered by a reminder. For example, in studies in which young kids were taught to imitate an action, six-month-olds could remember what to do for 24 (but not 48) hours, while nine-month-olds could remember what to do one month (but not three months) later.ĭespite this memory loss, childhood experiences have been found to influence adult behaviour years later, which suggests that traces of these memories could be stored somewhere in the brain that isn’t easy to access.

This includes both procedural memories, which allow us to carry out tasks without thinking about them (e.g., how to walk) and memories of events that happened to us.Ī child’s ability to remember things for long periods of time improves progressively throughout childhood. Because so many new neurons are being produced and form connections with each other in memory circuits, they might disrupt existing networks of memories that have already formed.īut it turns out that infants and toddlers can and do form memories. Neuroscientists believe that the rapid rate at which brain cells are being produced in childhood could be the cause of infantile amnesia. In adulthood, new cells are still being produced, but the rate of production in the hippocampus slows down,” says Dr Jhaveri. “In the hippocampus, new neurons are constantly being created. This region stores autobiographical memories from specific events in our lives, such as the coffee we had with a friend last week, or a family holiday we took years ago. This increase correlates with a growth in the number of brain cells – called neurons – and the connections between these cells.Ī part of the brain that is particularly important in forming memories is the hippocampus, says Dr Dhanisha Jhaveri, a researcher at the Queensland Brain Institute at The University of Queensland. When we’re born, our brains aren’t yet fully developed they continue to develop through infancy into adolescence and young adulthood.Īt birth, a baby’s brain is only a quarter of its adult size, growing to three-quarters the size of an adult brain by age two. The answer lies in the way that our brain’s ability to store memories changes as we grow.

So why is it that we can’t remember being a baby, or a toddler? A photograph taken in 1974 of a baby girl standing in the garden, Western Australia.
