Module 1: What Hypnosis Is and Isn't
What Hypnosis Is and Isn't
Knowledge check
Q1. Which of the following best describes the current scientific view of hypnosis?
- A. A special trance state in which the mind is completely controlled by the hypnotist
- B. A set of responses shaped by suggestion, focused attention, expectation, and imagination, which varies greatly among individuals ✓
- C. A form of sleep in which the subconscious mind becomes accessible
- D. A paranormal ability that only certain people can use on others
Why: Modern research generally views hypnosis as a psychological process involving focused attention, suggestion, and expectancy. Responses vary widely between people, and hypnotized individuals remain in control of their behavior rather than being mentally overpowered.
Q2. Which statement is a common myth about hypnosis?
- A. Suggestibility differs from person to person
- B. A hypnotized person can be made to do anything the hypnotist wants, even acts against their values ✓
- C. Hypnosis can be used to reduce pain in some clinical contexts
- D. Expectations about hypnosis can influence how someone responds to it
Why: The belief that hypnotized people lose all control and can be forced to act against their will is a popular myth. Research shows people do not carry out acts they find morally objectionable, and they can stop or refuse suggestions at any time.
Q3. What is the term for a person's capacity to respond to suggestions, which is a key factor in how well they respond to hypnosis?
- A. Hypnotic susceptibility ✓
- B. Cognitive dissonance
- C. Somnambulism
- D. Catharsis
Why: Hypnotic susceptibility (or hypnotizability) refers to how readily a person responds to hypnotic suggestions. It is a relatively stable trait that varies across the population, with some people being highly responsive and others showing little response.
Q4. Which of the following is a reason hypnosis is NOT the same as sleep?
- A. People under hypnosis are unconscious and cannot hear the hypnotist
- B. Brain activity during hypnosis resembles waking attention rather than sleep, and hypnotized people remain aware of their surroundings ✓
- C. Hypnosis always produces dreaming, just as sleep does
- D. Hypnotized people lose their memory of the entire session
Why: The word 'hypnosis' comes from the Greek word for sleep, but the state is not sleep. Hypnotized individuals stay aware and attentive, and brain studies do not show the patterns associated with sleep. Their focus is directed inward or toward the hypnotist's suggestions.
Q5. Which factor is most central to what happens during a hypnotic induction?
- A. The hypnotist's physical strength and eye contact
- B. The use of a swinging pocket watch to shift brain waves
- C. A participant's focused attention and responsiveness to suggestion ✓
- D. A chemical substance administered to induce a trance
Why: Hypnotic induction primarily works through focused attention and the participant's willingness to respond to suggestions. Props like pocket watches are not necessary and do not directly alter brain waves, and no drug is required for hypnosis.

Q1. Which 18th-century physician is most associated with the idea of 'animal magnetism' and is often considered an early precursor to modern hypnosis?
- A. Sigmund Freud
- B. Franz Mesmer ✓
- C. Jean-Martin Charcot
- D. Ivan Pavlov
Why: Franz Mesmer proposed that an invisible natural force, which he called animal magnetism, flowed through living things and could be manipulated to heal illness. His methods produced dramatic trance-like states, which later inspired the development of hypnosis.
Q2. What did the Royal Commission in Paris (1784) conclude about Mesmer's animal magnetism?
- A. That animal magnetism was a real physical force that could cure disease
- B. That the effects were caused by imagination rather than any magnetic fluid ✓
- C. That Mesmer should be awarded a state pension for his discovery
- D. That the effects were caused by electrical currents in the body
Why: The commission, which included Benjamin Franklin and Antoine Lavoisier, tested Mesmer's claims using blindfold and control experiments. They found that the effects depended on participants' expectations and imagination, not on any magnetic fluid.
Q3. James Braid is credited with coining the term 'hypnosis' in the 1840s. What does the word derive from?
- A. The Latin word for sleep, somnus
- B. The Greek god of sleep, Hypnos ✓
- C. The French word for trance, transe
- D. The Egyptian word for healing, sekhem
Why: Braid derived the term from Hypnos, the Greek god of sleep. He initially believed the state resembled sleep, though he later revised his view and emphasized that it was a distinct psychological state.
Q4. Which French neurologist at the Salpêtrière hospital worked with hypnosis in the 1870s and 1880s, contributing to its medical legitimacy?
- A. Hippolyte Bernheim
- B. Pierre Janet
- C. Jean-Martin Charcot ✓
- D. Émile Coué
Why: Jean-Martin Charcot used hypnosis to study hysteria and bring it into the realm of scientific study. His work drew wide attention, though his views on hypnosis were later challenged by the Nancy School led by Bernheim.
Q5. Which school of thought, centered in Nancy, France, argued that hypnosis was rooted in suggestion and was available to most people rather than being a sign of disease?
- A. The Vienna School
- B. The Nancy School ✓
- C. The Zurich School
- D. The Leipzig School
Why: The Nancy School, led by Hippolyte Bernheim and Ambroise-Auguste Liébeault, held that hypnosis was a product of suggestion and was not limited to hysterical patients. This view challenged Charcot's theory and shaped later understanding of the phenomenon.

Module 3: Suggestibility and Individual Differences
Suggestibility and Individual Differences
Knowledge check
Q1. Which term refers to the degree to which an individual responds to hypnotic suggestions?
- A. Hypnotic depth
- B. Suggestibility ✓
- C. Dissociation
- D. Trance induction
Why: Suggestibility is the measurable tendency to respond to suggestions, and it is the core individual difference studied in hypnosis research. Hypnotic depth describes the subjective intensity of trance, while dissociation and trance induction are related but distinct concepts.
Q2. Research on hypnotic suggestibility suggests that roughly what proportion of people are highly hypnotizable?
- A. Nearly everyone
- B. About 50 percent
- C. About 10 to 15 percent ✓
- D. Less than 1 percent
Why: Studies using standardized scales such as the Stanford Hypnotic Susceptibility Scale consistently find that around 10 to 15 percent of people are highly hypnotizable, with a similar proportion showing very low responsiveness. Most people fall in the moderate range.
Q3. Which standardized measure is most commonly used to assess hypnotic suggestibility in research?
- A. The Minnesota Multiphasic Personality Inventory
- B. The Stanford Hypnotic Susceptibility Scale ✓
- C. The Wechsler Adult Intelligence Scale
- D. The Beck Depression Inventory
Why: The Stanford Hypnotic Susceptibility Scale (SHSS) and its successors, such as the Harvard Group Scale, provide standardized suggestions and scoring procedures. This allows researchers to compare suggestibility across individuals and studies.
Q4. Which personality trait has been most consistently linked to higher hypnotic suggestibility?
- A. Neuroticism
- B. Absorption ✓
- C. Extraversion
- D. Conscientiousness
Why: Absorption, the tendency to become fully immersed in experiences such as imagination, music, or reading, correlates reliably with hypnotic suggestibility. Other traits show weaker or inconsistent relationships.
Q5. Which statement about hypnotic suggestibility is best supported by research?
- A. It is fixed at birth and cannot change over a lifetime.
- B. It is entirely determined by the skill of the hypnotist.
- C. It is a relatively stable trait that shows some genetic influence but can be influenced by experience. ✓
- D. It disappears completely after childhood.
Why: Twin studies suggest a substantial heritable component to hypnotic suggestibility, and it tends to be fairly stable across adulthood. However, environmental factors, practice, and expectations can still shape how a person responds, so it is neither purely fixed nor purely dependent on the hypnotist.

Q1. Which brain imaging technique measures changes in blood oxygenation as a proxy for neural activity and has been used to study hypnosis?
- A. Electroencephalography (EEG)
- B. Functional magnetic resonance imaging (fMRI)
- C. Positron emission tomography using radioactive glucose only
- D. Magnetoencephalography (MEG)
Q2. In neuroimaging studies of hypnotic suggestion, researchers have often reported changes in which brain network that is associated with attention and executive control?
- A. The default mode network only
- B. The visual cortex exclusively
- C. The cerebellum and brainstem
- D. Frontoparietal control network regions such as the anterior cingulate cortex
Q3. A study found that a suggestion to see a color was associated with altered activity in color-processing areas of the brain. What does this finding most directly suggest?
- A. Hypnosis creates entirely new sensory input from the eyes
- B. Hypnotic suggestions can modulate perception-related brain regions, though this alone does not prove a unique trance state
- C. Hypnosis has no measurable effect on the brain
- D. Only people with brain damage can be hypnotized
Q4. Why do many neuroscientists caution against interpreting hypnosis brain-imaging results as proof of a distinct altered state of consciousness?
- A. Brain imaging cannot detect any activity in the cortex
- B. Hypnotized and control participants often differ in expectations, motivation, and task engagement, which can explain the observed differences
- C. fMRI machines are too loud for participants to relax
- D. Hypnosis only occurs in sleep, so scanning is impossible
Q5. Which statement best describes the main limitation of EEG compared with fMRI for studying hypnotic states?
- A. EEG cannot record any brain signals at all
- B. EEG has excellent temporal resolution but poor spatial localization of deep brain sources
- C. EEG only works on children
- D. EEG measures blood flow more precisely than fMRI
Module 5
Module 5: Hypnosis in Clinical Practice
Hypnosis in Clinical Practice
Knowledge check
Q1. Which of the following best describes the role of hypnosis in clinical practice today?
- A. A standalone cure for major psychiatric disorders
- B. An adjunctive tool that may support treatment for conditions such as pain, anxiety, and habit disorders
- C. A method used exclusively to recover memories of past events
- D. A treatment that has been proven to replace all forms of medication
Q2. What does the term 'suggestibility' refer to in the context of hypnosis?
- A. The ability to remember events from early childhood
- B. The degree to which a person responds to suggestions and changes in perception, thought, or behavior
- C. A permanent personality trait that cannot be measured
- D. The tendency to resist all forms of persuasion
Q3. Which clinical application of hypnosis has the most consistent research support?
- A. Recovering accurate memories of childhood abuse
- B. Managing procedural and chronic pain as an adjunct to standard care
- C. Permanently curing schizophrenia
- D. Improving long-term memory capacity in healthy adults
Q4. Why is caution advised when using hypnosis to recover memories?
- A. Hypnosis always produces perfectly accurate recall of events
- B. Hypnotic procedures can increase confabulation and false memories, which may be held with high confidence
- C. Memories recovered under hypnosis are legally required to be destroyed
- D. Hypnosis permanently erases all memories from the period before treatment
Q5. What is a common misconception about people who are hypnotized?
- A. That they remain aware of their surroundings and can stop the session at will
- B. That they lose all control and will automatically act against their own values or wishes
- C. That they may experience altered attention and focus
- D. That response to hypnosis varies from person to person
Module 6
Module 6: Stage Hypnosis and the Myths of Control
Stage Hypnosis and the Myths of Control
Knowledge check
Q1. What is the most accurate description of why stage hypnosis subjects appear to act against their will?
- A. Hypnosis temporarily removes the subject's ability to refuse any suggestion
- B. Subjects are often willing participants who are responding to social expectations, role-play, and the suggestibility of the situation
- C. Stage hypnotists use a special drug in the subject's drink that induces compliance
- D. The hypnotist transfers a portion of their own will into the subject's mind
Why: Research on stage hypnosis points to volunteer selection, motivation to please, expectation, and role-play as key factors. Subjects who appear controlled are typically cooperating and interpreting cues as permission to behave in unusual ways.
Q2. Which of the following is a common myth about hypnosis that stage performances tend to reinforce?
- A. Hypnosis can increase suggestibility in some people
- B. Hypnotized people can be made to commit acts they find morally objectionable ✓
- C. Hypnosis is a state of focused attention and relaxation
- D. Suggestibility varies considerably from person to person
Why: The belief that hypnosis can override a person's morals is a popular myth. Experimental evidence shows that hypnotized subjects retain their values and will refuse suggestions that conflict with their principles, and that stage subjects are generally cooperating rather than helplessly controlled.
Q3. What does the term 'suggestibility' refer to in hypnosis research?
- A. The hypnotist's skill at delivering persuasive commands
- B. The degree to which a person responds to and experiences suggested changes in perception, memory, or behavior ✓
- C. The depth of trance a subject enters during an induction
- D. The number of times a subject can be hypnotized in one session
Why: Suggestibility is a trait describing how readily a person accepts and acts on suggestions. Researchers measure it with standardized scales, and it is a property of the subject's responsiveness rather than of the hypnotist's power.
Q4. Why do stage hypnotists typically select volunteers from the audience for their shows?
- A. Volunteers are required by law to participate in hypnosis demonstrations
- B. Hypnotists screen for people who are highly responsive, cooperative, and eager to perform, which makes the show more convincing ✓
- C. Only people with a specific brain condition can be hypnotized
- D. Audience volunteers are paid performers who are secretly working with the hypnotist
Why: Stage hypnotists pre-screen or select volunteers who show willingness and responsiveness. This selection effect means the observed effects reflect a self-selected group of enthusiastic participants rather than the general population.
Q5. Which statement best reflects the current scientific consensus on hypnosis?
- A. Hypnosis gives the hypnotist complete control over the subject's mind and body
- B. Hypnosis is a reliable tool for recovering accurate memories of past events
- C. Hypnosis can be a useful clinical tool for some people, such as in pain management, but it does not grant control over a person's will ✓
- D. Hypnosis has been proven to be nothing more than a form of sleep
Why: Mainstream research recognizes hypnosis as a real phenomenon with some clinical applications, particularly for pain and anxiety, while rejecting claims of mind control. It also cautions that hypnotically recalled memories can be unreliable and that hypnosis is not sleep.

Module 7: Evaluating Claims: Evidence, Limits, and Ethics
Evaluating Claims: Evidence, Limits, and Ethics
Knowledge check
Q1. Which of the following best describes the current scientific view of hypnosis?
- A. Hypnosis is a altered state of consciousness that allows people to access hidden memories perfectly.
- B. Hypnosis is a set of responsive suggestion-based experiences whose effects depend heavily on the person's expectations, motivation, and imagination.
- C. Hypnosis is a form of sleep in which the brain shuts down higher reasoning.
- D. Hypnosis gives the hypnotist direct control over a subject's will and behavior.
Q2. A claim states that a hypnotized person can recall events from childhood that they had forgotten, and these memories are always accurate. What is the most important reason to be skeptical?
- A. Hypnosis cannot affect memory at all, so the recall must be imagined.
- B. Hypnotic recall can increase confidence in memories without increasing their accuracy, and it can also introduce false or suggested details.
- C. Only trained psychologists can access memories, so the claim is automatically false.
- D. Childhood memories are never stored in the brain, so no recall is possible.
Q3. Which study design would provide the strongest evidence that a hypnosis technique produces a real effect beyond expectation?
- A. Asking participants after the session whether they felt the technique worked.
- B. Collecting testimonials from people who say the technique cured their symptoms.
- C. A randomized controlled trial comparing the technique to a credible control condition, such as a placebo or attention-matched procedure, with blinded outcome measurement.
- D. Observing a single highly responsive participant in depth over one session.
Q4. Why is it ethically important for a hypnotherapist to avoid promising guaranteed cures?
- A. Because hypnosis is illegal to advertise as a treatment in all countries.
- B. Because overstated promises can lead clients to delay or forgo effective medical care and can create unrealistic expectations and harm.
- C. Because hypnosis always makes people worse if they expect a cure.
- D. Because clients cannot consent to any form of suggestion-based treatment.
Q5. A stage hypnotist makes volunteers act silly on stage. Which explanation is most consistent with the evidence on hypnotic behavior?
- A. The volunteers' minds have been permanently altered and they cannot resist commands.
- B. Volunteers are typically selected for high suggestibility, and social motivation, role expectations, and the desire to cooperate with the performance strongly shape their behavior.
- C. The hypnotist is using a hidden drug that removes free will during the show.
- D. Volunteers are all actors who were secretly instructed beforehand to pretend.
