The New Hysteria

Via GeekPress: Nature reports on research into the origins of the psychological notion of repressed memory:

To see how long the idea of repressed memories have been around, a group of psychologists and literature scholars turned to historical writings.
They could not find a single description of repressed memory, also referred to as dissociative amnesia, in fiction or factual writing before 1800.

Apparently it was all just a Freudian slip...
