In Test 1 Mendelsohn and colleagues found that people in the PHA group (who could experience PHA) forgot more details from the movie than people in the non-PHA group (who could not experience PHA). But in Test 2, after the suggestion was cancelled, this memory loss was reversed. People in the PHA group correctly recognized just as many details from the movie as people in the non-PHA group. Somewhat surprisingly, however, the suggestion to forget was selective in its impact. Although people in the PHA group had difficulty remembering the content of the movie following the forget suggestion, they had no difficulty remembering the context in which they saw the movie.

Hypnosis, an enhanced state of inner focus, can be an effective tool for improving a range of symptoms, including those related to mood and learning. The ADHD drug methylphenidate (Concerta, Ritalin) has been shown to increase hypnotizability in a sample of patients with ADHD and thus may enable patients to benefit from adding hypnosis to their treatment regimens.
Braid soon assimilated Carpenter's observations into his own theory, realising that the effect of focusing attention was to enhance the ideo-motor reflex response. Braid extended Carpenter's theory to encompass the influence of the mind upon the body more generally, beyond the muscular system, and therefore referred to the "ideo-dynamic" response and coined the term "psycho-physiology" to refer to the study of general mind/body interaction.

Most relaxation techniques require daily practice to be effective. A variety of formats for teaching relaxation and meditation exist, including classes as well as individual sessions. Relaxation can be taught in 1 session by conducting and audio taping a relaxation session. Using the audio tape, patients can then practice the techniques daily at home. Methods such as progressive muscle relaxation are easy to learn; yoga, tai chi, and meditation can take years to master completely.
“I have been in the classroom for 22 years, both as a student and as a teacher. The Hypnotherapy Academy is the very best possible learning environment ever! The knowledge and expertise of the instructors are equally matched with their enthusiasm, clarity and humor. I found no other program that provides such comprehensive and thorough hypnosis training. The personal growth I experienced in THIS NURTURING ENVIRONMENT WAS PROFOUND!”
Cancer patients use relaxation and hypnosis. Evidence from randomized trials shows hypnosis and relaxation are effective for cancer-related anxiety, pain, nausea, and vomiting, particularly in children. Some practitioners also claim that relaxation techniques, particularly the use of imagery, can prolong life, although currently available evidence is insufficient to support this claim.
In the 2000s, hypnotherapists began to combine aspects of solution-focused brief therapy (SFBT) with Ericksonian hypnotherapy to produce therapy that was goal focused (what the client wanted to achieve) rather than the more traditional problem focused approach (spending time discussing the issues that brought the client to seek help). A solution-focused hypnotherapy session may include techniques from NLP.[13]
