The areas in the brain responsible for memory consolidation and retrieval - the hippocampus and prefrontal cortex - are not fully developed in children. The most common explanation for childhood amnesia is the nature of neurological development. It is common and experienced by many people. However, he may often not be able to recall what happened before that. In the late 19th century, Sigmund Freud, the founding father of psychoanalysis, described the phenomenon of 'infantile amnesia', in which people cannot recall events that took place during early childhood.Īn individual generally has memories of events in his life from the age of about four years. Why is it that certain events from your childhood are etched in your mind, while you may have the vaguest memory of some others? Here, we examine this phenomenon. While other members of the family may remember those days, you may face difficulty recollecting them. Your parents or relatives may fondly remember a peculiar mannerism that you had or talk about a specific incident when you were naughty as a toddler. "They want to be cooperative," she says, "so you have to be very careful not to put words in their mouth.During a family discussion, the conversation may sometimes veer towards your childhood days. The key to using children as witnesses is to make sure they are questioned in a noncoercive way, Peterson says. But studies have shown that they can, and that "the amount they remember is staggering." In the past, she says, courts thought children couldn't tell the difference between fact and fantasy. "And he can remember the pattern of his teardrops on the linoleum."įindings like that are persuading courts to allow more eyewitness testimony from children, Peterson says. "He remembers crying on the floor of the kitchen, and he remembers how upset he was," Peterson says. It was the day his mother went to the hospital to give birth to a sibling. But a child in one of Peterson's studies recalled an event from when he was just 18 months old. So several years ago, Bauer and her colleague Marina Larkina decided to study a group of children to see what happened to their memories over time.įrancis Csedrik remembers details of being bonked hard on the head when he was 4, and having to go to the emergency room. More studies provided evidence that at some point in childhood, people lose access to their early memories. So, she wondered, "Why is it that as adults we have difficulty remembering that period of our lives?" "What we found was that even as young as the second year of life, children had very robust memories for these specific past events," Bauer says. Then, in the 1980s, Bauer and other researchers began testing the memories of children as young as 9 months old, in some cases using gestures and objects instead of words. But it's only in the past decade that they have begun to figure out when childhood memories start to fade, which early memories are most likely to survive, and how we create a complete autobiography without direct memories of our earliest years.įor a long time, scientists thought childhood amnesia occurred because the brains of young children simply couldn't form lasting memories of specific events. Scientists have known about childhood amnesia for more than a century. "Most adults do not have memories of their lives for the first 3 to 3 1/2 years," says Patricia Bauer, a professor of psychology at Emory University. That's a classic example of a phenomenon known as childhood amnesia.
