André Muller Weitzenhoffer (1921 - 2004) was one of the most prolific researchers in the field of hypnosis in the latter half of the 20th century, having authored over 100 publications between 1949 and 2004. He was the recipient of several professional and academic awards, including the Distinguished Contributions to Scientific Hypnosis Award of the American Psychological Association in 1992.
Weitzenhoffer claimed that he became interested in hypnosis at age 12 after seeing a demonstration by a summer camp counselor and subsequently witnessing a stage hypnosis show.
Weitzenhoffer and Milton Erickson were friends and at times collaborators, with a mutual respect for each other's work.
At Stanford University, Weitzenhoffer collaborated with Ernest R. Hilgard in developing the Stanford Hypnotic Susceptibility Scale and the Stanford Profile Scales of Hypnotic Susceptibility, Forms I and II which are the most widely-referenced research tools in the field of hypnosis.
Joseph Wolpe (1915 - 1997) was one of the most influential figures in behavior therapy. Wolpe is most well known for his reciprocal inhibition techniques and systematic desensitization which revolutionized behavioral therapy.
Cognitive Behavioural Therapy (CBT) works on changing your negative thoughts, (or cognitions) about yourself or your circumstances into positive thoughts, which will allow you to approach life more positively.
Cognitive Behavioural Hypnotherapy (CBH) is where CBT is combined with hypnotherapy to produce a more effective form of therapy which often can produce more rapid results than standard CBT alone.
It helps people with negative, destructive or unhelpful thoughts to start creating only positive thoughts . This helps clients to deal with depression, self esteem issues, low confidence issues and self destructive behaviour. It is also is used in treating the other areas such as smoking cessation, weight loss, dealing with phobias etc.
