An evaluation of Woodard's theory of perceptually oriented hypnosis

This article evaluates Woodard's theory of Perceptually Oriented Hypnosis, a welcome addition to theories of hypnosis that emphasize the centrality of subjective experiences in understanding and studying hypnosis. With a focus on subjective experience. Woodard's account of perceptually oriented hypnosis is based on elements of humanistic, client-centered, and perceptual psychology. However, we contend that improvements in the operational clarity and coverage of the theory are necessary to optimize its utility and heuristic value. We also argue that it is important for Perceptually Oriented Hypnosis to address hypnotic phenomena, e.g., individual differences in suggestibility, involuntary responding to suggestions, stability of responding over time, widely recognized as essential to understanding hypnotic experience and responding. With these refinements, we believe that Woodard's theory would have a greater potential to enrich our understanding of both the unique experiences of individuals who undergo hypnosis and of hypnosis in general.     

Perceptually oriented hypnosis: cross-cultural perspectives

Literature is reviewed and summarized relevant to present cross-cultural, shamanic, and spiritual aspects of hypnosis. Explanations are offered within the framework of Woodard's theory of Perceptually Oriented Hypnosis. Research on cross-cultural aspects of hypnosis could enhance understanding of phenomenological and perceptual aspects of hypnosis, increase knowledge of hypnotic phenomena, and expand understanding of perceptual awareness. A summary of the qualitative research methodologies to enhance understanding of multicultural hypnotic experiences is presented. This groundwork provides for further exploration of cross-cultural hypnosis. Surprisingly, some suggestions have remained underutilized or not published.     

Perceptually oriented hypnosis

This theoretical article explores postulates representative of a perceptual frame of reference for a better understanding of hypnotic experiencing. This author contends that Perceptual Psychology, a theory first conceptualized by Snygg and Combs, as revised by Combs, Richards, and Richards in 1988, and Perceptually Oriented Hypnosis provide an effective way of understanding hypnosis, the therapist-client relationship, and has some implications as well for better comprehending psychopathology. Perceptually oriented hypnotic principles are shown to enhance the characeristics of the adequate personality, expand the phenomenal field, change personal meanings, and change aspects of the phenomenal self in the context of hypnosis. Implications for understanding differing views and conflicting perceptions of reality held by scientists and researchers are discussed. Implications for Dissociative Identity Disorder are also addressed. Research utilizing Giorgi's research methodology and Wasicsko's qualitative procedure for assessing educators' dispositions is suggested.     

Response to Beshai's "Quantitative and qualitative research in hypnosis: comment on Woodard"

This paper clears up some misunderstandings of Woodard's Phenomenological and Perceptual Research Methodology presented by Beshai in a recent critique. Beshai's critique helps demonstrate and validate a number of themes in Woodard's Perceptually Oriented Hypnosis. First, for each of us, our historical learnings provide the basis for scientific progress but at the same time may impede new views and even a more comprehensive understanding of hypnosis. Second, hypnosis is fundamentally a process of differentiating personal meanings that can be vastly different for various individuals. Third, Beshai uses a quantitatively based approach to understanding phenomenon different from Woodard's qualitative research process. Last, holistic understanding of hypnosis is impeded when aspects of the phenomenal field are taken quantitatively out of context.     

Quantitative and qualitative research in hypnosis: a commentary on Woodard

In recent articles Woodard extended the Snygg and Combs theory of "Perceptually Oriented Hypnosis" to effect a rapprochement with a Phenomenology of Hypnosis. Both use the "Phenomenal Field" of consciousness, but they provide different interpretations and approaches to the essence of hypnosis. Snygg and Combs were heavily reliant on Gestalt psychology with a Cartesian dualism while Phenomenology maintains the unity of quality and quantity within consciousness. This commentary presents the philosophical basis for the two methods used to arrive at the essence of hypnosis in clinical practice.     

Hypnosis and clinical pain

Hypnosis has been demonstrated to reduce analogue pain, and studies on the mechanisms of laboratory pain reduction have provided useful applications to clinical populations. Studies showing central nervous system activity during hypnotic procedures offer preliminary information concerning possible physiological mechanisms of hypnotic analgesia. Randomized controlled studies with clinical populations indicate that hypnosis has a reliable and significant impact on acute procedural pain and chronic pain conditions. Methodological issues of this body of research are discussed, as are methods to better integrate hypnosis into comprehensive pain treatment.     

Uses of hypnosis in evaluating malingering and deception

Hypnosis, as a method of detecting deception, is examined with respect to its forensic applications. The degree of hypnotizability and whether formal hypnotic procedures may be employed are discussed with both the relevant clinical and legal issues in mind. Finally, the use of hypnosis in determining the authenticity of psychosomatic conditions is addressed.     

Does 'hypnosis' by any other name smell as sweet? The efficacy of 'hypnotic' inductions depends on the label 'hypnosis'

Hypnosis is associated with profound changes in conscious experience and is increasingly used as a cognitive tool to explore neuropsychological processes. Studies of this sort typically employ suggestions following a hypnotic induction to produce changes in perceptual experience and motor control. It is not clear, however, to what extent the induction procedure serves to facilitate suggested phenomena. This study investigated the effect on suggestibility of (a) a hypnotic induction and (b) labelling that procedure 'hypnosis.' Suggestibility of participants was tested before and after an adapted hypnotic procedure, which was either labelled as 'hypnosis' or as 'relaxation.' The hypnotic procedure produced a modest increase in suggestibility when it was called 'relaxation,' but a very significant increase if it was labelled 'hypnosis.' The results are important for both clinical and experimental applications and indicate that labelling an induction procedure 'hypnosis' is an important determinant of subsequent responses to suggestion.     

HYPNOSIS AS SUBJECTIVE EXPERIENCE

Å s , A. & O sstvold , S. Hypnosis as subjective experience. Scand. J. Psychol ., 1968, 9, 33–38.—Fifty female students were interviewed about their subjective experiences during experimental hypnosis. A majority of the experiences correlated positively with measured depth of hypnosis. A factor analysis suggested three experiential factors, differently correlated with hypnotic depth.     

Cultivating a “Chairside Manner”: Dental Hypnosis,Patient Management Psychology,and the Origins of Behavioral Dentistry in America, 1890–1910

Discussions regarding the use of hypnotism in dentistry featured prominently in dental journals and society proceedings during the decades around the turn of the twentieth century. Many dentists used hypnotic suggestion either as the sole anesthetic for extractions or in conjunction with local and general anesthetics for excavation and cavity filling. With the heralding of humanitarian dentistry and improved local anesthesia around 1905, a number of dentists advocated using suggestion psychology to calm nervous patients and increase their comfort and satisfaction levels while undergoing dental procedures. The practice of hypnotic suggestion with local and general anesthesia in providing patients with increasingly painless procedures constituted the earliest variety of behavioral dentistry, a discipline not fully developed until the closing decades of the twentieth century. Hypnosis and suggestion became driving forces for psychological applications in the formative years of behavioral dentistry.     

On the advantage of autobiographical memory pliability: implantation of positive self-defining memories reduces trait anxiety

This paper is devoted to the mechanism of the positive construction of autobiographical memory. Positive construction consists of the spontaneous transformation of memories in the direction of the subjective enhancement of self-competence in past activities to anticipate improvement over time. We speculated that trait anxiety may indicate a failure to exhibit this mechanism that results in a deficit of affirmative self-esteem. We hypothesised that the implantation of positive self-defining memories in anxiety-evoking domains would decrease trait anxiety. One hundred twenty adults recollected three negative self-defining memories. Then, half of the participants imagined episodes of desired behaviour that differed from the originally recollected ones either in discussion or in hypnosis. Thirty participants experienced a hypnotic state without any references to memories, and the rest formed the control group. Subjects from the “Memory Implantation in Hypnosis” group became unable to distinguish the originally reported memories from the imagined ones, exhibited decreased trait anxiety scores after a 4-month delay, and reported enhanced self-esteem. In contrast, the participants from the “Hypnosis with no reference to the past” group exhibited decreased scores at a short delay but later returned to their original scores. These findings highlight the power of cured episodic-like autobiographical memory for updating the self.     

Hypnosis and belief: A review of hypnotic delusions

Hypnosis can create temporary, but highly compelling alterations in belief. As such, it can be used to model many aspects of clinical delusions in the laboratory. This approach allows researchers to recreate features of delusions on demand and examine underlying processes with a high level of experimental control. This paper reviews studies that have used hypnosis to model delusions in this way. First, the paper reviews studies that have focused on reproducing the surface features of delusions, such as their high levels of subjective conviction and strong resistance to counter-evidence. Second, the paper reviews studies that have focused on modelling underlying processes of delusions, including anomalous experiences or cognitive deficits that underpin specific delusional beliefs. Finally, the paper evaluates this body of research as a whole. The paper discusses advantages and limitations of using hypnotic models to study delusions and suggests some directions for future research.     

Not all group hypnotic suggestibility scales are created equal: individual differences in behavioral and subjective responses

To examine the influence of hypnotic suggestibility testing as a source of individual differences in hypnotic responsiveness, we compared behavioral and subjective responses on three scales of hypnotic suggestibility: The Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS: A; Shor, R. E., Orne, E. C. (1962). Harvard Group Scale of Hypnotic Susceptibility. Berlin: Consulting Psychologists Press); the Carleton University Responsiveness to Suggestion Scale (CURSS; Spanos, N. P., Radtke, H. L., Hodgins, D. C., Stam, H. J., Bertrand, L. D. (1983b). The Carleton University Responsiveness to Suggestion Scale: Normative data and psychometric properties. Psychological Reports, 53, 523-535); and the Group Scale of Hypnotic Ability (GSHA; Hawkins, R., Wenzel, L. (1999). The Group Scale of Hypnotic Ability and response booklet. Australian Journal of Clinical and Experimental Hypnosis, 27, 20-31). Behavioral and subjective responses to the CURSS were significantly different than those on the HGSHS: A and GSHA. More participants were classified as "low suggestible" on the CURSS and they reported subjective experiences more similar to everyday mentation. Attitudes and expectancies of participants who received the GSHA were less predictive of responding, but rates of responding and subjective experiences were similar on the GSHA and the HGSHS: A. Discussion focuses on implications for the use of group hypnotic suggestibility scales.     

Literalism as a marker of hypnotic "trance": disconfirming evidence

The responses given by highly hypnotizable, hypnotic subjects and those of unhypnotizable subjects who simulated hypnosis to questions of the type, "Do you mind telling me your name?" and "Do you mind standing up?" were contrasted. The purpose was to examine Erickson's (1980) assertion that literalism (answering "yes" or "no" verbally or nonverbally without any cognitive elaboration) is a marker of hypnotic "trance." Simulators exhibited a greater rate of literalism than hypnotic "virtuosos" (i.e., extreme scorers on both group and individual hypnotizability measures). Hypnotized subjects and nonhypnotized subjects approached in the campus library responded comparably. Because less than a third of hypnotic virtuosos responded literally, our results strongly refuted Erickson's assertion that literalism is a cognitive feature of hypnosis.     

Conditional reflexes as related to hypnosis and hypnotic techniques.

Hypnosis has never been adequately explained in terms of conceptual framework of most schools of psychotherapy. The psychoanalytic concept that it consists of submission and surrender of important ego functions to the therapist does not explain all observed facts. During my wartime studies and since, I have been impressed by the observation that the patient's ego is by no means powerless and defenseless, even during a deep state of trance, i.e., in states of trance sufficiently deep to eliminate awareness of painful body injuries (1965). Erickson (1954) has shown on many occasions that in resistant subjects one of the best ways to induce trance is to encourage the patient to resist as much as he can. Haley (1963) has pointed out in detail that at the beginning of any hypnotic relationship there evolves a subtle battle for "one-upmanship." These observations certainly show that surrender in the psychological sense is by no means an aspect of even the most successfully induced trance states.

Cognitive flexibility in hypnosis: response to change communication from the hypnotist.

It was predicted that modification of response as it indexes cognitive flexibility in the hypnotic subject is related to susceptibility to hypnosis and the difficulty of the hypnotic task attempted. Experiment 1 isolated two distinct hypnotic tasks (easy and difficult); alternative forms of each item conveyed either clear or unclear structure concerning the response that was perceived as most appropriate. In Experiment 2, 101 subjects were administered hypnotic induction procedures and tested for modification of response on both items; for each subject, the hypnotist posed a conflict in communication by plausibly requesting an alteration in response from the behavior that the subject had chosen to indicate previously. Change data demonstrated that hypnotic subjects modified their behavior in hypnosis, but their cognitive flexibility was much more relevant to easy than to difficult tasks. Results highlight a further dimension of role enactment as well as the special role cognitive skills in play in our understanding of performance on hypnotic test items.     

A preliminary phenomenological study of being hypnotized and hypnotizing

This paper presents phenomenological research conducted following Woodard's phenomenological and perceptual research methodology for understanding hypnotic experiencing. The research emphasizes examining the internal experiencings of individuals involved in hypnotic experiencing. Examples are presented of Individual Situated Structures and the General Structures from both a group of 8 participants who hypnotized their clients and another group of 17 individuals who volunteered to be hypnotized. The explicated themes identified in hypnotic experiencing (the hypnotic relationship, phenomenology of trance, use of imagination, problem with psychic energy, a gestalt of experiencing, and linear-nonlinear experiencing) are discussed. The author discusses limitations of this study and suggestions for further work.     

Altered and asymmetric default mode network activity in a "hypnotic virtuoso": an fMRI and EEG study

Very highly hypnotizable subjects are rare, easily induced, and able to manifest the whole spectrum of hypnotic phenomena, including post-hypnotic amnesia. The aim of this study was to detect and localize by means of quantitative functional MRI and EEG changes in cortical activity during hypnosis induction and deep "pure hypnosis" in a hypnotic "virtuoso" subject. We focused on areas forming the default mode network (DMN), since previous studies found that very highly suggestible subjects in hypnosis showed decreased activity in anterior DMN. During undisturbed hypnosis, our "virtuoso" subject showed not only detectable changes in DMN, but also peculiar activations of non-DMN areas and hemispheric asymmetries of frontal lobe connectivity. Our findings confirm that hypnosis is associated with significant modulation of connectivity and activity which involve the DMN but are not limited to it, depending on the depth of the hypnotic state, the type of mental content and emotional involvement.
