What currently appears to be the best explanation for early childhood amnesia, and why is this explanation better than those that psychologists previously considered?
What will be an ideal response?
During early childhood, the hippocampus forms many new neurons. The new neurons make it easy to form new memories rapidly, but as that process happens, it reorganizes the hippocampus in a way that may erase previous memories. Therefore, learning is rapid, but so is forgetting. This is better than previous explanations because it focuses on why preschoolers forget their memories. Most of the previous explanations tried to explain why preschoolers don't form long-term semantic memories, but in fact they do form them. They just forget rapidly. This explanation is better than Freud's, because Freud assumed early childhood to be highly traumatic, when in fact it seldom appears to be. Furthermore, this new explanation accords with the fact that infant rats and mice also learn rapidly but forget rapidly.
