<unk> is the expression (as by speaking or writing) of the content of consciousness without censorship as an aid in gaining access to unconscious processes. The technique is used in psychoanalysis (and also in psychodynamic theory) which was originally devised by Sigmund Freud out of the hypnotic method of his mentor and colleague, Josef Breuer. Freud described it as such: "The importance of<unk> is that the patients spoke for themselves, rather than repeating the ideas of the analyst; they work through their own material, rather than parroting another's suggestions".
