Doctors from the Renaissance period also practiced treatments that resembled emotional flooding for patients afflicted with
demonic possession. Paul Olsen says, "Possession was truly a diagnostic category of its day, encompassing practically any form of religi-culturally determined
psychopathology.” Practitioners frequently attributed many ailments, as well as most odd behaviors, now recognized as
mental diseases to
Satan and other
demons. This was particularly true when the ravings, actions, or
hallucinatory experiences could be considered
blasphemous or
heretical. Cures for possession by the devil focused on spiritual salvation and were aimed at getting to a person's unconscious and unacceptable impulses and wishes. Many people who confessed under the duress of torture may well have been releasing repressed material. In all likelihood, pain stimulated a flood of unconscious crimes, such as murderous rage against authority figures, incest wishes, or any number of socially determined offenses.
Exorcism rituals aimed at rescuing the soul from Satan. The effects of the procedure may have also relieved some of the body's anguish through release of emotional pain. These techniques resembled modern emotional flooding techniques. The emphasis on emotion was strong in exorcism techniques; the exorcist tried to temper its expression or to liberate it. ==Nineteenth century==
