Hypnosis

A state of focused attention and reduced peripheral awareness in which a person becomes more responsive to suggestion, typically entered through an agreed procedure led by a clinician or by the person alone.

Related: Hypnotic Trance, Suggestion
Hypnotherapy

The clinical use of hypnosis as an adjunct within a planned psychological or medical treatment, combining induction, therapeutic suggestion, and evidence-based intervention rather than hypnosis as a standalone cure.

Related: Hypnosis, Therapeutic Suggestion
Suggestion

A communication that invites a person to experience a change in perception, thought, feeling, or behavior without coercion or argument, often phrased to allow the person to accept or modify what is offered.

Related: Therapeutic Suggestion, Suggestibility
Suggestibility

A person's tendency to respond to suggestions, influenced by context, expectancy, rapport, and absorption; it is not a fixed trait and does not measure gullibility or weakness of character.

Related: Hypnotic Responsiveness, Absorption
Hypnotic Responsiveness

The degree to which a person shows the classic phenomena of hypnosis, such as analgesia, amnesia, or involuntary movement, when given standardized suggestions; it varies widely and is only moderately stable across time.

Related: Suggestibility, Hypnotic Phenomena
Absorption

The capacity to become deeply engaged in an experience while ignoring surrounding distractions; it is a measurable trait linked to, but not identical with, hypnotic responsiveness.

Related: Hypnotic Responsiveness, Hypnotic Trance
Hypnotic Phenomena

Observable responses classically associated with hypnosis, including analgesia, amnesia, age regression, catalepsy, ideomotor movement, and perceptual alteration; their presence supports but does not define hypnosis.

Related: Ideomotor Response, Hypnotic Analgesia
Ideomotor Response

An involuntary-looking movement produced by suggestion, such as a hand lifting when told it is becoming light; it is a common marker of responsiveness and is used in induction and assessment.

Related: Hypnotic Phenomena, Chevreul Pendulum Effect
Chevreul Pendulum Effect

The tendency for a held pendulum or similar device to swing in the direction a person expects or imagines, illustrating how expectancy and ideomotor action shape experience without deliberate movement.

Related: Ideomotor Response, Expectancy
Hypnotic Analgesia

Reduction of pain through hypnotic suggestion without loss of consciousness; it is used as an adjunct for procedural and chronic pain and is distinct from pharmacological anesthesia.

Related: Hypnotic Phenomena, Therapeutic Suggestion
Hypnotic Trance

A descriptive label for the subjective state often reported during hypnosis, such as relaxed focus or time distortion; the term is used loosely because no single physiological signature defines it.

Related: Hypnosis, Absorption
Expectancy

A person's anticipation about what will happen during hypnosis, which strongly shapes responsiveness; clinicians address it during preparation because unrealistic fears or hopes both affect outcomes.

Related: Suggestibility, Myths About Hypnosis
Myths About Hypnosis

Common misconceptions, such as that hypnosis is sleep, mind control, or a truth serum, or that a person can be forced to act against their will; correcting them during informed consent improves safety and rapport.

Related: Expectancy, Informed Consent
Informed Consent

The process of explaining the nature, purpose, risks, alternatives, and limits of hypnosis, confirming understanding, and obtaining voluntary agreement before proceeding, documented in the record.

Related: Myths About Hypnosis, Contraindication
Contraindication

A condition or circumstance in which hypnosis should be avoided, modified, or deferred, such as untreated psychosis, certain dissociative disorders, or use for recovering disputed memories.

Related: Screening, Informed Consent
Screening

A structured pre-hypnosis review of medical, psychiatric, and psychosocial history to identify risks, set goals, and decide whether hypnosis is appropriate, adapted, or should be postponed.

Related: Contraindication, Intake Interview
Intake Interview

The initial clinical conversation gathering presenting concerns, history, expectations, and goals; it establishes rapport and informs whether and how hypnosis will be integrated into care.

Related: Screening, Treatment Plan
Induction

The process of guiding a person into hypnosis using focused attention, relaxation, imagery, or eye fixation; it is a means to an end, not the therapeutic work itself.

Related: Deepening, Hypnotic Trance
Deepening

Techniques used after induction to intensify involvement, such as counting down stairs, imagery of descent, or fractionation; deepening is tailored to the person's response and comfort.

Related: Induction, Fractionation
Fractionation

A deepening method in which the person is briefly brought out of hypnosis and re-induced, often repeatedly, to increase depth; it is used only when the person tolerates the transitions well.

Related: Deepening, Emergence
Therapeutic Suggestion

A carefully worded message aimed at a clinical goal, such as comfort, confidence, or reduced nausea; effective suggestions are specific, positively phrased, and congruent with the person's values.

Related: Suggestion, Ego-Strengthening
Ego-Strengthening

A set of suggestions designed to build self-confidence, resilience, and coping capacity, often used in brief therapy; it emphasizes the person's existing strengths rather than symptom removal alone.

Related: Therapeutic Suggestion, Self-Hypnosis
Guided Imagery

The use of suggested mental scenes, such as a safe place or healing light, to influence emotion and physiology; it is often paired with hypnosis and chosen collaboratively with the person.

Related: Therapeutic Suggestion, Relaxation Training
Relaxation Training

Structured practice in reducing physiological arousal through breathing, progressive muscle relaxation, or imagery; it is a common induction component and a standalone behavioral skill.

Related: Guided Imagery, Self-Hypnosis
Self-Hypnosis

A learned skill in which a person induces and uses hypnosis independently, often with a practiced cue and script; it supports generalization of gains between sessions.

Related: Homework Assignment, Ego-Strengthening
Homework Assignment

Between-session practice, such as self-hypnosis or imagery rehearsal, agreed with the person to consolidate skills; tasks should be brief, realistic, and reviewed at the next contact.

Related: Self-Hypnosis, Generalization
Generalization

The transfer of skills and gains from the therapy session to everyday settings; it is promoted through practice, varied contexts, and self-directed application.

Related: Homework Assignment, Self-Hypnosis
Emergence

The planned return from hypnosis to ordinary alertness, often with counting and orientation cues; it is conducted calmly and checked so the person leaves oriented and comfortable.

Related: Termination, Adverse Reaction
Termination

The structured ending of hypnotherapy, including review of gains, planning for maintenance, and closing the professional relationship; it is distinguished from emergence, which ends a single trance.

Related: Emergence, Treatment Plan
Adverse Reaction

An unwanted response to hypnosis, such as anxiety, dizziness, intrusive memories, or failure to emerge as expected; it is managed by reassurance, grounding, and follow-up, and documented.

Related: Emergence, Documentation
Abreaction

A sudden release of intense emotion or imagery during hypnosis, sometimes linked to distressing memories; it requires containment, grounding, and clinical judgment rather than continued probing.

Related: Adverse Reaction, Contraindication
Documentation

The clinical record of consent, screening, induction approach, suggestions used, responses, and any adverse events; it supports continuity, supervision, and accountability.

Related: Informed Consent, Scope of Practice
Scope of Practice

The boundaries of what a clinician is trained, licensed, and permitted to do; hypnosis does not extend those limits, and clinicians refer when a concern falls outside their competence.

Related: Documentation, Contraindication
Treatment Plan

A written outline of goals, target problems, planned interventions, session frequency, and measures of progress; hypnosis is included only where it serves those agreed goals.

Related: Intake Interview, Termination
Rapport

A trusting working alliance built through attentive listening, clear communication, and respect for the person's autonomy; it underpins safe induction and honest informed consent.

Related: Informed Consent, Intake Interview
Pacing and Leading

A communication approach that first matches the person's current experience and language, then gently guides toward a desired response; it supports rapport and acceptance of suggestions.

Related: Suggestion, Rapport
Age Regression

A suggested experience of returning to an earlier time; it is used cautiously for resource building or review, never to recover presumed historical facts, because memory is reconstructive.

Related: Hypnotic Phenomena, Contraindication
Hypnotic Amnesia

Suggested or spontaneous difficulty recalling events of the trance; it is a classic responsiveness marker and is not used to suppress material the person needs to process.
