Therapeutic Hypnosis - Considers "hypnosis" as "a state-relationship within which the therapist wishes to increase healing potential, and will do everything possible to maximize the relationship with the patient. Furthermore, he/she will change induction techniques, suggestions, interpretations, and all interventions to facilitate symptom improvement. The last thing he/she wants to do is apply a standardized technique equally to all patients. The therapist will build this relationship with the patient as strongly as possible over many sessions in which resistances and transference reactions are dealt with and resolved.
Investigative Hypnosis -The purpose of using Investigative Hypnosis is to refresh memory. In the forensic application, hypnosis is applied to recover the memory of the subject and is to be conducted with witnesses and preferably recorded by both audio and visual means with a witness present during the interview. This differs from therapeutic hypnosis where the session(s) may be conducted in private and are concerned with only the subject and therapist.
