Green and Lynn (2000) conducted a meta analysis of 59 experiments investigating the efficacy of hypnosis on smoking cessation. Their conclusions were: There is mixed, inconclusive evidence for whether hypnosis is any better than placebos. Hypnosis treatments were generally confounded with educational interventions and cognitive/behavioral interventions, ...

Hypnotic states are associated with increased theta wave activity. Hypnotically susceptible participants also exhibit hemispheric beta wave asymmetry, but non-susceptible participants do not (Sabourin, Cutcomb, Crawford and Pribram, 1990). References Sabourin, M. E., Cutcomb, S. D., Crawford, H. J., & Pribram, K. (1990). EEG correlates of hypnotic ...

Overall, while there are developing cognitive neuroscience theories of how hypnotic states are produced, there does not appear to be any known cognitive neuroscience basis for individual differences in hypnotic susceptibility based on a reasonable Google Scholar, Web of Science and Scopus search on the topic. There is at least some evidence to suggest that ...

Wearing those big headphone is indirectly a way to isolate yourself from the surrounding sound. That is usually a prelude for relaxation, or meditation. (In people with audiotory disorder, or with authism, this is a way they can feel good as that remove a big source of stimulis) On the other side for the heavy metal, study have found it can be a stress ...

The answer lies in what is known of the conscious, unconscious and the presconscious parts of the mind, with preconscious is the scientific name for the subconscious, however, for the purposes of this answer and because of how the theory of hypnosis is put together, I will refer to the preconscious as the subconscious. When I was learning about the basis of ...

Looking at the client testimonials on the website you provided it looks like it varies from 1 session to a few more. Like any other therapy it seems to depend on the client and problem being dealt with. You could ask the therapist how many sessions you are likely to need for your problem in order to find out whether you would like to go ahead or not. I am ...

Despite quite of lot of research looking for personality correlates of hypnotisability no very clear links have been found. There is evidence of weak associations between hypnotisability and absorption (the capacity to direct a great deal of attention to a narrow range of stimuli, such as getting caught up in film or book) and also of associations between ...

For scientifically supported texts, I would recommend the textbooks produced by the American Society of Clinical Hypnosis (linked here) as a good place to start. None of these are free (legally), though. They also produce a bibliography of articles and books (currently some 9 pages) that provide some additional handy references.

Answering your first question... This paper does a handy job of describing the situation. Specifically, it describes how "more effective" may not be the correct way of looking at the comparison between hypnosis and placebo. Specifically, these methods may function differently, depending on the activity of the individual's prefrontal cortex: "In ...

A literature review was conducted Barak et al. (2008) that compared the effectiveness of internet-based psychotherapy in general (not specifically hypnosis). From their abstract, the results indicate that: The overall mean weighted effect size was found to be 0.53 (medium effect), which is quite similar to the average effect size of traditional, face-to-...

I believe this question is impossible to "answer" because the inherent premises in the question are based on the assumption that there are two discrete dichotomous phenomena, "hypnotism," and "meditation," which can somehow be meaningfully "defined," and, then, "compared." Both "hypnosis" and "meditation" are figuratively vast conceptual collages of ...

There is no a single answer for this, but I will tell from what I have read of Milton Erickson's ideas. Everyone is suceptible to hypnosis. The difficult in being hypnoized depends on the person's experience more than a specific part of the brain, and this implies that the most important thing is how the hipnotist is capable of capturing the person's ...

I am studying hypnotherapy at University and this is what I have learnt. During the induction stages of hypnosis, the body becomes more and more relaxed and the brain enters changing levels of brain wave pattern. There are five brainwave frequencies, however there are four main different brainwave patterns when looking at hypnosis. These are Beta wave ...

Preamble First of all, I would like to point out that hypnosis, and therefore hypnotherapy, is generally considered pseudo-scientific within the scientific community and therefore this question can be classed as off-topic here by some. However, there are trained and licensed hypnotherapists who share the same question on whether or not to use hypnotherapy ...

There is a really nice and recent review about the current state of research regarding hypnosis, which also cites the resource of another answer here). I will quote here the part about EEG studies but would recommend to read the whole article (if you can't access the article, sci-hub can probably help you). 3.1. The EEG spectrum Historically, the ...

Before I give the answer to your question, I must point out that pursuits into recalling past events through hypnosis etc. can lead to mixed results. You can be lucky and gain true insight into a past event previously forgotten, but it cannot generally be relied upon in legal and forensic terms due to the risk of false memories being inadvertently implanted....

Since I vaguely remember a similar question not that long ago, let me use this one to quote from one the few peer-reviewed papers (doi link; preprint pdf). that discusses the notion of "mind control": Mind control is a common plot device in many genres of fiction. Its ubiquity is perhaps unsurprising: the prospect of the explicit, full control of the ...

It's highly plausible (judging from your description) that you induce some sort of hypnotized state. I highly doubt it's strongly related to heavy metal though. The state of mind you're hinting at is not really a state between the subconscious and conscious. It's your mind deceiving your body that you're asleep without losing awareness. The increased visual ...

Just to add to @what's great answer (that this is not a testable question), a while ago I watched a Derren Brown episode where he successfully hypnotizes someone to assassinate a co-conspirator. This was supposedly to test the Manchurian Candidate hypothesis (and incorporating a polka-dot dress) - a conspiracy theory that the CIA used hypnosis to train ...

I am studying hypnotherapy myself and from what I am led to believe, there is no "spectrum of how able people are to be hypnotised". Everyone who wants to be hypnotised can be. How quickly they are hypnotised depends on the experience of the hypnotherapist and their methods used. Take a look at Elman and Ericksonian Inductions in Google. There are good ...

Main difference is that the meditation is self-induced and with full self-awareness, whereas hypnosis is usually induced by another person (unless is self-hypnosis which is self-induced) and the person is in state of trance, amnesia or unconscious. Hypnosis is defined by the U.S government as "the bypass of the critical factor of the conscious mind and the ...
