[edit[->0]] 1890s
The idea of psychoanalysis was developed in Vienna in the 1890s by Sigmund Freud[->1], a neurologist[->2] interested in finding an effective treatment for patients with neurotic[->3] or hysterical[->4] symptoms. Freud had become aware of the existence of mental processes that were not conscious as a result of his neurological consulting job at the Children's Hospital, where he noticed that many aphasic[->5] children had no organic cause for their symptoms. He wrote a monograph about this subject.[2] In the late 1880s, Freud obtained a grant to study with Jean-Martin Charcot[->6], the famed neurologist and syphilologist, at the Salpêtrière[->7] in Paris. Charcot had become interested in patients who had symptoms that mimicked general paresis[->8]. Freud's first theory to explain hysterical symptoms was the so-called "seduction theory[->9]". Since his patients under treatment with this new method "remembered" incidents of having been sexually seduced in childhood, Freud believed that they had actually been abused only to later repress those memories. This led to his publication with Dr. Breuer in 1893 of case reports of the treatment of hysteria.[3] This first theory became untenable as an explanation of all incidents of hysteria. As a result of his work with his patients, Freud learned that the majority complained of sexual problems, especially coitus interruptus[->10] as birth control. He suspected their problems stemmed from cultural restrictions on sexual expression and that their sexual wishes and fantasies had been repressed. Between this discovery of the unexpressed sexual desires and the relief of the symptoms by abreaction, Freud began to theorize that the unconscious mind had determining effects on hysterical symptoms.
His first comprehensive attempt at an explanatory theory was the then unpublished Project for a Scientific Psychology in 1895.[4] In this work Freud attempted to develop a neurophysiologic theory based on transfer
