> early childhood I think this is a property of neural net style memories. Old data isn't "deleted" from the network; instead, new reinforcement makes older memories less accurate. This means memories that were particularly strong can persist for a long time; a lot of "overwriting" with unrelated data is necessary to dilute out a traumatic memory. This can start at any point in life, but memories that happened in childhood have more time to cause the problems you mentioned.
