Conversation so far:
What was the Seduction theory concerning?
had described to him, modified by what he called his "pressure technique" and his newly developed analytic technique of interpretation and reconstruction.
What was the "pressure technique"?
explained these at first as having the function of "fending off" memories of infantile masturbation, but in later years he wrote that they represented Oedipal fantasies.
What more can you tell me about the seduction theory?
Freud's proposing that unconscious memories of infantile sexual abuse were at the root of the psychoneuroses.

Question: When was he proposing this theory?
Self-contained rewrite: When was Sigmund Freud proposing Seduction theory?
