Therapeutic Hypnosis: Researchers Uncover More Of Its Scientific Basis

Hypnosis refers to a set of procedures involving an induction – which could be relaxing or actively imagining something – followed by one or more suggestions. The purpose of the induction is to induce a mental state in which participants are focused on instructions from the therapist, and are not distracted by everyday concerns. One reason why hypnosis is of interest to scientists is that participants often report that their responses feel automatic and effortless.

Most inductions produce equivalent effects. But inductions aren’t actually that important. Surprisingly, the success of hypnosis doesn’t rely on special abilities of the hypnotist either – although building rapport with subjects will certainly be valuable in a therapeutic context.

Rather, the main driver for successful hypnosis is one’s level of "suggestibility”. This is a term which describes how responsive we are to suggestions. We know that suggestibility doesn’t change over time.

Most people are moderately responsive to hypnosis. This means they can have vivid changes in behavior and experience in response to hypnotic suggestions. By contrast, a small percentage (around 10%) of people are mostly non-responsive. But most research on hypnosis is focused on another small group (15-20%) who are highly responsive.

Considerable evidence from brain imaging reveals that these individuals are not just imagining these responses. Indeed, the brain acts differently when people respond to hypnotic suggestions than when they imagine or voluntarily produce the same responses.

Preliminary research has shown that highly suggestible individuals may have unusual functioning and connectivity in the prefrontal cortex. This is a brain region that plays a critical role in a range of psychological functions, including planning and the monitoring of one’s mental states.

There is also some evidence that highly suggestible individuals perform more poorly on cognitive tasks known to depend on the prefrontal cortex, such as working memory. However, these results are complicated by the possibility that there might be different subtypes of highly suggestible individuals.

These neurocognitive differences may lend insights into how highly suggestible individuals respond to suggestions: they may be more responsive because they’re less aware of the intentions underlying their responses.

For example, when given a suggestion to not experience pain, they may suppress the pain but not be aware of their intention to do so. This may also explain why they often report that their experience occurred outside their control. Neuroimaging studies have not as yet verified this hypothesis, but hypnosis does seem to involve changes in brain regions involved in monitoring of mental states, self-awareness and related functions.

Although the effects of hypnosis may seem unbelievable, it is now well accepted that beliefs and expectations can dramatically impact human perception. In this light, perhaps hypnosis isn’t so bizarre after all. Seemingly sensational responses to hypnosis may just be striking instances of the powers of suggestion and beliefs to shape our perception and behavior. What we think will happen morphs seamlessly into what we ultimately experience.

Hypnosis requires the consent of the participant or patient. You cannot be hypnotised against your will and, despite popular misconceptions, there is no evidence that hypnosis could be used to make you commit acts against your will.

HYPNOSIS AS MEDICAL TREATMENT

Meta-analyses, studies that integrate data from many studies on a specific topic, have shown that hypnosis works well when it comes to treating certain conditions. These include irritable bowel syndrome and chronic pain.

As researchers gradually learn more, it has become clear that this captivating phenomenon has the potential to reveal unique insights into how the human mind works. This includes fundamental aspects of human nature, such as how our beliefs affect our perception of the world and how we come to experience better control over our actions and emotions.
