Douglas J Tataryn, John F Kihlstrom
Two experiments that studied the effects of hypnotic suggestions on tactile sensitivity are reported. Experiment 1 found that suggestions for anesthesia, as measured by both traditional psychophysical methods and signal-detection procedures, were linearly related to hypnotizability. Experiment 2 employed the same methodologies in an application of the real-simulator paradigm to examine the effects of suggestions for both anesthesia and hyperesthesia. Significant effects of hypnotic suggestion on both sensitivity and bias were found in the anesthesia condition but not for the hyperesthesia condition...

Paul F Dell
The author explores the nature of hypnosis, which he characterizes as a motivated mode of neural functioning that enables most humans to alter, to varying degrees, their experience of body, self, actions, and world. The essence of hypnosis is not to be found in hetero-hypnosis; instead, it lies in the spontaneous self-activation of that mode of neural functioning. The hypnosis field has substantially lost sight of spontaneous self-activation, because the word hypnosis is usually used to mean hetero-hypnosis...

Changes in the sense of agency are defining feature of hypnosis. The Sense of Agency Rating Scale (SOARS) is a 10-item questionnaire, administered after a hypnosis session to assess alteration in the sense of agency. In the present study, a Hungarian version of the measure (SOARS-HU) is presented. The SOARS-HU and the Phenomenology of Consciousness Inventory (PCI) were administered to 197 subjects following hypnotizability screening with the Harvard Group Scale of Hypnotic Susceptibility Scale, Form A (HGSHS:A)...

The classic Stroop task demonstrates the persistent and automatic effects of the meaning of color words that are very hard to inhibit when the task is to name the word color. Post-hypnotic instructions may enable highly-hypnotizable participants to inhibit the automatic access to word meaning. Here we compared the consequences of hypnosis alone and hypnosis with post-hypnotic instructions on the Stroop effect and its facilitation and inhibition components. Importantly, we studied the mechanisms of the hypnosis effects at the neural level by analyzing EEG frequencies...

The authors tested the hypothesis that hypnotic age regression produces a shift from secondary- to primary-thought processing in hypnotizable participants. Thirty participants were tested for hypnotizability using the Elkins Scale of Hypnotizability (EHS). Participants were exposed to a tailored hypnotic arm-levitation induction and a hypnotic suggestion to age regress to 5 years of age and to have a dream. Primary-process thinking was assessed using the Primary-Process Thinking Scale. An independent t test with 2 levels of hypnotizability (middle and high) showed high hypnotizables demonstrated higher ratings of primary thought processing than those in the middle group...

The division of cognition into primary and secondary processes is an important part of contemporary psychoanalytic metapsychology. Whereas primary processes are most characteristic of unconscious thought and loose associations, secondary processes generally govern conscious thought and logical reasoning. It has been theorized that an induction into hypnosis is accompanied by a predomination of primary-process cognition over secondary-process cognition. The authors hypothesized that highly hypnotizable individuals would demonstrate more primary-process cognition as measured by a recently developed cognitive-perceptual task...

This study examined the relationship between the Hypnotic Induction Profile (HIP) and several psychological tests: Tellegen Absorption Scale (TAS), Spontaneity Assessment Inventory-Revised (SAI-R), Dissociative Experiences Scale (DES), Short-Form Boundary Questionnaire (SFBQ), Mini Locus of Control (MLOC), Testoni Death Representation Scale (TDRS), and the Interpersonal Reactivity Index (IRI). Two hundred and forty volunteers were administered the above tests; 78 of them were also administered the HIP, and its scores were compared to those on the other tests...

This study investigated group hypnotizability in 167 adolescents (ages 13-17) in an inpatient behavioral healthcare setting through use of the Waterloo-Stanford Group Scale, Form C. It also investigated the influence of hypnotic inductions on group hypnotizability. Adolescents were randomly assigned to either a group session of hypnosis (n = 84) with a hypnotic induction or a comparison "no-induction" group (n = 83) that received identical suggestions without a hypnotic induction. Adolescents' imaginative absorption and dissociation were measured to examine their influence on hypnotizability...

REVIEW
Maria Paola Brugnoli
Hypnotic treatment in severe chronic diseases, for pain and symptoms relief, has proven efficacy as adjuvant therapy, and should be offered to any individual, who expresses an interest in this method. While some theorize hypnotizability as a changing attribute of the individual, there is a growing body of literature that indicates hypnotizability may be characterized as a constellation of potentially modifiable attitudes and skills, which are strongly influenced by related factors, as suffering, in severe chronic diseases...

Groups of participants (N = 164) were randomly assigned to three conditions: Group 1 received a trance induction, Group 2 received task-motivational instructions, and Group 3-"cold start" control-was simply told, "We will begin the hypnosis procedure now." All participants received the Creative Imagination Scale suggestions and then completed the Creative Imagination Scale and Inventory Scale of Hypnotic Depth. The three conditions did not differ significantly either on the Creative Imagination Scale or in reported hypnotic depth...

Anxiety is common among breast-cancer survivors. This analysis examined the effect of a hypnotic relaxation therapy, developed to reduce hot flashes, on anxiety levels of female breast-cancer survivors. Anxiety was assessed using a numeric analog scale and the Hospital Anxiety and Depression Scale-Anxiety subscale. Significant reductions in anxiety were found from pre- to postintervention for each weekly session and were predictive of overall reductions in anxiety from baseline to after the last intervention...

We evaluated the influence of hypnotizability, pain expectation, placebo analgesia in waking and hypnosis on tonic pain relief. We also investigated how placebo analgesia affects somatic responses (eye blink) and N100 and P200 waves of event-related potentials (ERPs) elicited by auditory startle probes. Although expectation plays an important role in placebo and hypnotic analgesia, the neural mechanisms underlying these treatments are still poorly understood. We used the cold cup test (CCT) to induce tonic pain in 53 healthy women...

Hypnosis has proven clinical utility, yet changes in brain activity underlying the hypnotic state have not yet been fully identified. Previous research suggests that hypnosis is associated with decreased default mode network (DMN) activity and that high hypnotizability is associated with greater functional connectivity between the executive control network (ECN) and the salience network (SN). We used functional magnetic resonance imaging to investigate activity and functional connectivity among these three networks in hypnosis...

According to recent findings, interhemispheric interactions and information connectivity represent crucial mechanisms used in processing information across various sensory modalities. To study these interactions, the authors measured bilateral electrodermal activity (EDA) in 33 psychiatric outpatients. The results show that, during congruent Stroop stimuli in hypnosis, the patients with higher hypnotizability manifest a decreased level of interhemispheric information transfer measured by pointwise transinformation (PTI) that was calculated from left and right EDA records...

The aim of this article is to complement the recently revised American Psychological Association (APA) definition of hypnotizability. It (a) lists a few differences in sensorimotor integration between subjects with high (highs) and low (lows) hypnotizability scores in the ordinary state of consciousness and in the absence of suggestions, (b) proposes that hypnotizability-related cerebellar peculiarities may account for them,

Earlier studies have shown hypnotizability-related postural effects of visual suppression and of leg and neck proprioceptive alteration. This study completes this investigation by demonstrating the postural effects of asymmetric tactile foot stimulation in standing participants with different hypnotizability scores. During this stimulation, body sway changed in medium-to-high more than in low-to-medium hypnotizable participants. Findings support the view that high hypnotizability is associated with higher vulnerability of posture to sensory alteration; together with earlier results, they suggest a role of the cerebellum in the observed hypnotizability-related differences and prompt investigation of cerebral structures and factors potentially responsible for both the cognitive and physiological aspects of hypnotizability...

Measuring hypnotizability is an integral part of hypnosis research and is also relevant for predicting effectiveness of hypnosis-based therapies. The Elkins Hypnotizability Scale (EHS) was designed to meet the needs of modern hypnosis research and clinical practice. Reliability, validity, and normative data were explored by subjecting 230 participants to the EHS and Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C). The EHS demonstrated adequate internal consistency (α = .78), its items showed good discriminating ability, and scores of the two scales were highly correlated (ρ = ...

Some highly hypnotizable individuals have reported changes in objects' color with suggestions given in normal waking state. However, it is not clear whether this occurs only in their imagination. The authors show that, although subjects could imagine colors, a posthypnotic suggestion was necessary for seeing altered colors, even for a hypnotic virtuoso. She reported posthypnotic color alterations also selectively in response to specific target shapes in briefly presented object arrays. Surprisingly, another highly hypnotizable person showed a very different pattern of results...

During the 19th century, high hypnotizability was considered to be a form of psychopathology that was inseparable from hysteria. Today, hypnotizability is considered to be a normal trait that has no meaningful relationship with psychopathology. Psychiatric patients generally manifest medium to low hypnotizability. Nevertheless, several psychiatric diagnoses are marked by an unexpectedly large proportion of patients with high hypnotizability. This is especially true of the diagnostic categories that were subsumed by the 19th-century concept of hysteria: dissociative identity disorder, somatization disorder, and complex conversion disorders...

Whereas numerous studies have investigated hypnotic analgesia, few have investigated hypnotic anaesthesia. Using magnetoencephalography (MEG) we investigated and localized brain responses (event-related fields and oscillatory activity) during sensory processing under hypnotic anaesthesia. Nineteen right handed neurotypical individuals with moderate-to-high hypnotizability received 100 vibrotactile stimuli to right and left index fingers in a random sequence. Thereafter a hypnotic state was induced, in which anaesthetic suggestion was applied to the left hand only...
