The term was coined by Sigmund Freud, and the concept was the subject of his 1899 paper "Screen Memories".
Freud was struck by the presence, in himself and in other adults, of vivid but bland memories standing from early childhood; and he came to believe that their strength and their preservation both derived from their association with other, less innocent infantile occurrences.
As he concluded in his 1899 paper, "the falsified memory is the first that we become aware of: the raw material of memory-traces out of which it was forged remains unknown to us in its original form.
"[2] Later writers have emphasised the element of psychological trauma underpinning the screen memory, as well as the way it can encapsulate in miniature the core conflicts of childhood.
