I read one of Elizabeth Loftus' books when I was struggling after I began to have some particularly troubling memories from childhood that I had no prior recollection of.
As far as I can recall she is absolutely determined to convince the world that it is not possible to forget a trauma and then remember it at a much later date.
She is, of course, unable to prove that this is not possible for this to happen but what she did find was that it is possible for people 'remember' things that didn't happen.
She created a 'lost in the mall' experiment where people were told that a childhood scenario had happened to them and (some of them) began to believe it.
It was all linked to the 'false memory' debate of the 90s.
She worked very hard to undermine anybody who had experienced a trauma and forgotten it by saying the memories were 'planted' by therapists.
I read her work while I was trying to work out if what I was remembering was real or not. I also read plenty of work that supported that traumatic memories could be blocked out and remembered later, it was very common amongst holocaust survivors and there is plenty of research showing that children who have grown up with Social Care involvement will block out traumatic incidents that they then remember in later life and these are corroborated by their Social Services records.
I, myself, had my 'forgotten' traumatic memories corroborated also.
Elizabeth Loftus has dedicated her academic life to undermining the testimony of trauma survivors.
