This paper examines research on three hypnotic phenomena: suggested amnesia, suggested analgesia, and “trance logic.” For each case a social-psychological interpretation of hypnotic behavior as a voluntary response strategy is compared with the traditional special-process view that “good” hypnotic subjects have lost conscious control over suggestion-induced behavior. I conclude that it is inaccurate to describe hypnotically amnesic subjects as unable to recall the material they have been instructed to forget. Although amnesics present themselves as unable to (...) remember, they in fact retain control over retrieval processes and accommodate their recall (or lack of it) to the social demands of the test situation. Hypnotic suggestions of analgesia do not produce a dissociation of pain from phenomenal awareness. Nonhypnotic suggestions of analgesia and distractor tasks that deflect attention from the'noxious stimuli are as effective as hypnotic suggestions in producing reductions in reported pain. Moreover, when appropriately motivated, subjects low in hypnotic suggestibility report pain reductions as large as those reported by highly suggestible hypnotically analgesic subjects. Finally, the data fail to support the view that a tolerance for logical incongruity (i.e., trance logic) uniquely characterizes hypnotic responding. So-called trance-logic-governed responding appears to reflect the attempts of “good” subjects to meet implicit demands to report accurately what they experience. (shrink)

This article examines the neurobiological basis of the healing power attributed to shamanic practices in the Andes and Brazil in light of the pharmacology of neurotransmitters and the new technological explorations of brain functioning. The psychotropic plants used in shamanic psychiatric cures interfere selectively with the intrinsic neuromediators of the brain. Mainly they may alter: (1) the neuroendocrine functioning through the adrenergic system by controlling stressful conditions, (2) the dopaminergic system in incentive learning and emotions incorporation, (3) the serotoninergic system (...) in modulating behaviors, and mood, and (4) basic functions implied in anxiety or depression. PET scans and functional magnetic resonance imaging studies of hypnotic trance and altered states of consciousness may provide a useful model for the neurophysiological phenomena of shamanic drum-and-dance trance. The reorganization of cortical areas and the direct interconnections between the prefrontal cortex and the dopaminergic reward centers in the limbic system are of particular significance for human social judgment and symbolic processing. Those centers—including the hypothalamus and the amygdala (associated with psychosomatic equilibrium, memory, and emotion) are enhanced. This arousal may be amplified in order to induce a cathartic crisis—the shamanic trance. It is suggested that through this holistic approach the shaman empirically interferes in neurobiological dysfunctions. (shrink)

In recent decades, the focus in autism research progressively expanded. It presently offers extensive material on sensorimotor disturbances as well as on perceptive-cognitive preferences of people with autism. The present article proposes not only a critical interpretation of the common theoretical framework in autism research but also focuses on certain experiences common to some people with autism and which can be appropriately understood by phenomenology. What I will call “hypnotic experiences” in autism are moments in which some individuals withdraw (...) into intense sensorial and perceptive experiences. Following their examples, I use the term “hypnosis” primarily to describe a trance state in which the individuals become highly alert to and awake for an experience of a totally new kind. Through a close analysis of autobiographical writings from people with autism I defend the idea that the particularity of hypnotic experiences in autism consists in a certain qualitative shift within experience itself: what changes, in the hypnotic moments, is the way a person with autism relates to his/her own bodily experiences. If this qualitative shift is indeed difficult to account for within a reifying and intellectualist research perspective, phenomenology offers a large conceptual framework for understanding it. Phenomenology, and precisely, phenomenological psychopathology, will thus emerge as a major device in accounting for such “hypnotic experiences”. The argument mainly draws on the twofold structure of experience which is traditionally used in phenomenological research: it claims that in hypnotic experience people with autism are inclined to focus on non-reified “sensings”, “perceivings” and “movings”, and thus leave aside the object itself and any intentional reification of it. Finally, I will claim that this restriction to mere non-reified sensings might lead to a completely new conception of self and world. In the hypnotic experiences of autism, neither the subject nor the object come to a full-blown and independent existence. A thorough phenomenological analysis of hypnotic experience in autism therefore also has to face the question of a corresponding ontology of these experiences. (shrink)

Social stimuli grab our attention: we attend to them in an automatic and bottom-up manner, and ascribe them a higher degree of saliency compared to non-social stimuli. However, it has rarely been investigated how variations in attention affect the processing of social stimuli, although the answer could help us uncover details of social cognition processes such as action understanding. In the present study, we examined how changes to bottom-up attention affects neural EEG-responses associated with intentional action processing. We induced an (...) increase in bottom-up attention by using hypnosis. We recorded the electroencephalographic µ-wave suppression of hypnotized participants when presented with intentional actions in first and third person perspective in a video-clip paradigm. Previous studies have shown that the µ-rhythm is selectively suppressed both when executing and observing goal-directed motor actions; hence it can be used as a neural signal for intentional action processing. Our results show that neutral hypnotic trance increases µ-suppression in highly suggestible participants when they observe intentional actions. This suggests that social action processing is enhanced when bottom-up attentional processes are predominant. Our findings support the Social Relevance Hypothesis, according to which social action processing is a bottom-up driven attentional process, and can thus be altered as a function of bottom-up processing devoted to a social stimulus.

As an artist I am interested in creative states of consciousness and the direct expression of altered states of consciousness in forms such as musical improvisation and the automatic writings and drawings of the Surrealist Artists. I have been investigating a particular spectrum of altered states characterized by an enhanced experience where out-of-the-ordinary information is accessed or an enhanced ability is realized beyond what would ordinarily be possible. Within this realm we would find the ‘peak performance’ state of athletes and (...) musicians, as well as a state of intellectual inspiration where a complex problem is solved and also the phenomenon of premonition. It is related to the ‘flow state’ as described in Flow, The Psychology of Optimal Experience (Mihályi Csíkszentmihályi, 1990) and the experience of the American clairvoyant Edgar Cayce who resolved complex medical ailments when in a self-induced hypnotic trance. Additional examples include Haitian Vodou ritualized possession and all experiences where healing and foretelling of the future takes place through a communion with spirits. It is a broad spectrum that has been described in various ways throughout history and within all cultures. But though the descriptions vary, this spectrum of consciousness shares the common characteristic of accessing extraordinary information or demonstrating extraordinary skill or ability. This article is an attempt to help clarify and define this particular spectrum of consciousness. (shrink)

The Voice of Laruelle, the philosopher What is a voice in the context of the arts and philosophy? In the space of the philosopher's voice, in the complex grammar of his language is played his philosophical timbre, his own space, his particular voice, composed of concepts, articulated by the laws of coherence of the common philosophical language, with hypnotic specificities. These specificities are precisely the fruit of processes formerly called rhetoric, which I call non-hypnotics, one of whose functions is (...) just to speak in a double space: the common reference space of the reader or listener, and the conceptual virtual space peculiar to the philosopher. To the extent that the reader must pay increased and permanent attention to this double space, the philosophical trance effect, equivalent to the Ericksonian hypnotic trance, is facilitated. The difficulty of this double reading is the incessant passage from one code to another, which is also a hypnotic fascination. Heidegger prolongs and renews its structures and draws some effects from them, which provoke in the mind of the reader as an over-flow, a saturation effect, which itself favors the philosophical trance. Thus, each voice seeks to captivate the mind by confusing it with concepts, which seem at first sight familiar, but which reveal themselves with the use which is made, like formidable concepts to the power of unaccustomed fascination. One of the pleasures of reading Lareuelle's philosophy is due to this type of fascination with the philosophical voice and its language. (shrink)

This paper is a historical study of stage hypnotism from the early nineteenth through the early twentieth centuries. The hypnotists' stage performances over this period reveal cultural tensions related to modernization. Public responses to these shows also indicate the shifting dynamics of reform. When mesmerists first toured the U.S. in the early nineteenth century, the hypnotic trance confirmed popular belief in the ultimate perfectibility of the individual and society. By the late nineteenth century, however, hypnotic shows seemed (...) more a model for human enslavement than liberation. Medical experts also began to express concern at the possible health damage hypnotism might inflict. Despite stage hypnotists' efforts to defend their art, hypnotism became increasingly marginalized as the growth of the middle class and of mass culture dictated an increasingly sanitized popular culture.

Although we are sympathetic to his central thesis about the illusion of will, having previously advanced a similar proposal, Wegner's account of hypnosis is flawed. Hypnotic behavior derives from specific suggestions that are given, rather than from the induction, of trance, and it can be observed in 90% of the population. Thus, it is very pertinent to the illusion of will. However, Wegner exaggerates the loss of subjective will in hypnosis.

In lieu of an abstract, here is a brief excerpt of the content:Matter and Spirit in the Age of Animal MagnetismEric G. WilsonDuring the Romantic period, writers on both sides of the Atlantic explored the sleepwalker as a merger of holiness and horror. Emerging when scientific thinkers for the first time were connecting spirit to electricity and magnetism, the somnambulist became to certain Romantics a disclosure of the difficulty of harmonizing unseen and seen, agency and necessity. This problem prominently arose (...) in Anton Mesmer's late eighteenth-century experiments in animal magnetism, in which the sleepwalker proved a paradox: an opaque revelation of transparent currents and an unconscious vehicle of sophisticated thought. Romantics such as Coleridge embraced the somnambulist as an embodiment of these troubles involved in relating motion and meaning. Coleridge and those who responded to him saw in the hypnotized human this sobering possibility: the invisible requires the visible to make itself manifest while the visible needs the invisible to become significant. 1 This is sublime and sinister: to elevate a material form to spiritual power is transcendence; to sink the boundless into a body is grotesque.Here I explore the philosophical implications of animal magnetism, the place of the sleepwalker in the history of ideas, and the role of the hypnotized human in Romantic writers, especially Coleridge. I also meditate on relationships between matter and spirit, machine and human, word and thing. Along the way, I place the history of ideas and the works of Romantic writers in mutually illuminating dialogues. The literary texts shed fresh light on philosophical problems while the ideas reveal hidden literary elements.The somnambulistic trance had been around long before Mesmer's magnetic sleeps. For centuries, shamans had used auto-hypnosis to sound [End Page 329] their souls and other-hypnosis to cure their tribe-members' ailments. However, somnambulism could not become a scientific phenomenon until Europeans in laboratories began to study electricity and magnetism. In the early modern period, Paracelsus argued that a vital fluid courses through the cosmos. The human being draws this flow like a magnet attracts force. When the body pulls to itself evil effluvia, it falls ill. To return patients to health, Paracelsus placed magnets on painful areas. He hoped to extract the unwanted current and return it to the cosmic swirl. 2 In "magnetizing" spirit, Paracelsus opened a door for empirical inquiry into the invisible world. In 1600, William Gilbert claimed that magnets correspond to the earth: both are animated by universal attraction and repulsion. 3 By the end of the seventeenth-century, Newton proposed that things are impelled by a force that draws and repels. Newton's theory of gravity inspired natural philosophers of the next centuries to search for a principle of which the magnet and the spark are manifestations. 4During the second half of the eighteenth century and the early part of the nineteenth, natural philosophers explored electricity and magnetism with unprecedented precision. In 1752, Benjamin Franklin revealed the mystery of lightning and perhaps the spark of life. 5 Inspired by Franklin, F. C. Oetinger, J. L. Fricker, and Prokop Divisch developed a theology of electricity, based on the belief that God is the electrical current. 6 Later in the century, Luigi Galvani and Alessandro Volta debated over whether the galvanic flow might be the origin and principle of life itself. 7 A few years before Franklin harvested lightning, John Michell argued that the magnetic force is not constrained to lodestones but is possibly pervasive. Some years later, Franz Aepinus suggested that magnetism and electricity manifest a deep energy. Soon after, C. A. de Coulomb discovered the mathematical law by which electrical and magnetic forces operate (Whittaker, pp. 50–59).These findings led to the breakthroughs of the nineteenth century. 8 In 1807, Humphry Davy hypothesized that chemical elements interact through electromagnetic affinity or repulsion. 9 In 1820, H. C. Oersted demonstrated the correspondence between electricity and magnetism. The same year, A. M. Ampere formulated the laws by which electrical and magnetic currents interact (Whittaker, pp. 81–86). Michael Faraday in 1831 revealed electromagnetic induction and thus inaugurated a second Copernican revolution: he showed that matter is not solid and discrete but a field of electromagnetic energy. 10 The dreams of [End...

The readiness potential (RP) is one of the most controversial topics in neuroscience and philosophy due to its perceived relevance to the role of conscious willing in action. Libet and colleagues reported that RP onset precedes both volitional movement and conscious awareness of willing that movement, suggesting that the experience of conscious will may not cause volitional movement (Libet, Gleason, Wright, & Pearl, 1983). Rather, they suggested that the RP indexes unconscious processes that may actually cause both volitional movement and (...) the accompanying conscious feeling of will (Libet et al., 1983; pg. 640). Here, we demonstrate that volitional movement can occur without an accompanying feeling of will. We additionally show that the neural processes indexed by RPs are insufficient to cause the experience of conscious willing. Specifically, RPs still occur when subjects make self-timed, endogenously-initiated movements due to a post-hypnotic suggestion, without a conscious feeling of having willed those movements.

We examined two potential correlates of hypnotic suggestibility: dissociation and cognitive inhibition. Dissociation is the foundation of two of the major theories of hypnosis and other theories commonly postulate that hypnotic responding is a result of attentional abilities . Participants were administered the Waterloo-Stanford Group Scale of Hypnotic Susceptibility, Form C. Under the guise of an unrelated study, 180 of these participants also completed: a version of the Dissociative Experiences Scale that is normally distributed in non-clinical populations; (...) a latent inhibition task, a spatial negative priming task, and a memory task designed to measure negative priming. The data ruled out even moderate correlations between hypnotic suggestibility and all the measures of dissociation and cognitive inhibition overall, though they also indicated gender differences. The results are a challenge for existing theories of hypnosis. (shrink)

have recently provided a compelling demonstration of enhanced attentional control under post-hypnotic suggestion. Using the classic color-word interference paradigm, in which the task is to ignore a word and to name the color in which it is printed (e.g., RED in green, say ''green''), they gave a post-hypnotic instruction to participants that they would be unable to read. This eliminated Stroop interference in high suggestibility participants but did not alter interference in low suggestibility participants. replicated this pattern and (...) further demonstrated that it is not due to a visual strategy (such as blurring or looking at a different location). As a historical footnote, we describe a ''case study'' from 18 years ago in which we observed the same result using a hypnotic instruction to a single highly suggestible individual that he could not read. The elimination of Stroop interference has important implications for both the study of attention and the study of hypnosis. (shrink)

According to the theoretical framework relating hypnosis to attention, baseline attentional functioning in highly hypnotizable individuals should be more efficient than in low hypnotizable individuals. However, previous studies did not find differences in Stroop-like tasks in which the measure indicative of the Stroop interference effect was based on response latencies. This study was designed to determine whether subjects with different levels of hypnotic susceptibility show differences in baseline attentional functioning. To assess this hypothesis, high, medium, and low hypnotizable subjects (...) performed a Stroop task designed to evaluate accuracy performance, before being subjected to hypnotic induction. Results showed that the Stroop interference effect was smaller in high hypnotizable subjects than in low hypnotizable subjects, whereas it was not different between high, and medium hypnotizable subjects. This outcome supports the notion that baseline attentional functioning is related to hypnotic susceptibility. (shrink)

The ‘default mode’ network refers to cortical areas that are active in the absence of goal-directed activity. In previous studies, decreased activity in the ‘default mode’ has always been associated with increased activation in task-relevant areas. We show that the induction of hypnosis can reduce anterior default mode activity during rest without increasing activity in other cortical regions. We assessed brain activation patterns of high and low suggestible people while resting in the fMRI scanner and while engaged in visual tasks, (...) in and out of hypnosis. High suggestible participants in hypnosis showed decreased brain activity in the anterior parts of the default mode circuit. In low suggestible people, hypnotic induction produced no detectable changes in these regions, but instead deactivated areas involved in alertness. The findings indicate that hypnotic induction creates a distinctive and unique pattern of brain activation in highly suggestible subjects. (shrink)

Studies in economic decision-making have demonstrated that individuals appreciate social values supporting equity and disapprove unfairness when distributing goods between two or more parties. However, this seems to critically depend on psychological mechanisms partly pertaining to the ingroup–outgroup distinction. Little is known as to what extent economic bargaining can be manipulated by means of psychological interventions such has hypnosis. Here we show that a hypnotic ingroup versus outgroup suggestion impacts the tolerance of unfairness in an Ultimatum Game. Specifically, the (...) ingroup suggestion was associated with significantly greater acceptance rates of unfair offers than the outgroup suggestion, whereas hypnosis alone exerted only small effects on unfairness tolerance. These findings indicate that psychological interventions such as hypnotic suggestion can contribute to ingroup favoritism and outgroup rejection. (shrink)

The hypnosis technique is currently used in the medical field and influences directly the patient's state of relaxation, perception of the body and its visual imagination. There is evidence to suggest that hypnosis state may help patients to better achieve the task of motor imagination, which is central in rehabilitation protocols after a stroke. However, the hypnosis technique could also alter the activity in motor cortex. To the best of our knowledge, the impact of hypnosis on the EEG signal during (...) a movement or an imagined movement is poorly investigated. In particular, how event-related desynchronization (ERD) and event-related synchronization (ERS) patterns would be modulated for different motor tasks may provide a better understanding of the potential benefits of hypnosis for stroke rehabilitation. To investigate this purpose, we recorded EEG signals from 23 healthy volunteers who performed real movements and motor imageries in closed eye condition. Our results suggest that the state of hypnosis changes the sensorimotor beta rhythm during the ERD phase but maintains the ERS phase in the mu and beta frequency band suggesting a different activation of the motor cortex in the hypnotized state.

The present study investigated how the magnitude the word blindness suggestion effect on Stroop interference depended on hypnotic suggestibility when given as an imaginative suggestion and under conditions in which hypnosis was not mentioned. Hypnotic suggestibility is shown to be a significant predictor of the magnitude of the imaginative word blindness suggestion effect under these conditions. This is therefore the first study to show a linear relationship between the imaginative word blindness suggestion effect and hypnotic suggestibility across (...) the whole hypnotizability spectrum. The results replicate previous findings showing that highs respond to the word blindness suggestion to a greater extent than lows but extend previous work by showing that the advantage for those higher on the hypnotizability spectrum occurs even in a non-hypnotic context. Negative attitudes about hypnosis may not explain the failure to observe similar effects of the word blindness suggestion in less hypnotizable individuals. (shrink)

Here, we describe how Casas Grandes Medio period (AD 1200 to 1450) shamanic practices of the North American Southwest used tobacco shamanism, a ritual stance called the Tennessee Diviner (TD) posture, and cultural expectations to generate trance experiences of soul flight and divination. We introduce a conceptual model that holds that specific trance experiences are the emergent result of human minds interacting with additional factors including entheogens, cultural expectations, physiological states, postures/movement, and sound/stimulation. Experimental and ethnographic evidence indicates (...) initiating trance with either tobacco intoxication or the TD posture accompanied with a rapidly beating drum or rattle corresponds with perceptions of soul flight, transformation, and divination/information acquisition. Both have similar results but pairing them together as they were during the Medio period likely helped ensure the culturally desired trance experiences. This practice of mutually reinforcing factors was likely part of tobacco‐based shamanism found in other New World cultures as well. We suggest our general model can be applied to other contexts to examine how various aspects of trance induction interact to produce the cultural patterns (and resulting cosmological and spiritual frameworks) anthropologists have documented in other cultures.

Altered States of Consciousness is an umbrella term applied in the study of psychological, sociological and religious phenomena that are regularly encountered experientially in the study of trance, possession, and shamanism, all of which have complex and problematic links with music. Beginning with trance, and stressing the pervasive sexual imagery invoked, this paper reviews the role ofASC in these three areas in the anthropology of religion.

The present study examined the trait-like nature of hypnotic suggestibility by examining the stability of hypnotic responsiveness in a test–retest design in which the procedures were administered either live or by audiotape. Contrary to the idea that hypnotizability is a largely immutable, stable trait, scores on the scale of hypnotic responsiveness decreased significantly at the second session. Measures of subjective experiences and expectancies accounted for a sizable portion of the variance in hypnotic responding, both at initial (...) test and at retest. Participants became disengaged with the hypnotic procedures at retest. Participants who received the hypnotic induction by audiotape did not differ from participants who received it live. The results are consistent with sociocognitive and altered state theories of hypnosis, and underline the important role of subjective experiences in hypnotic responding. (shrink)

Forming implementation intentions has been consistently shown to be a powerful self-regulatory strategy. As the self-regulation of thoughts is important for the experience of involuntariness in the hypnotic context, investigating the effectiveness of implementation intentions on the suppression of thoughts was the focus of the present study. Participants were randomly assigned to one of four conditions . Results showed that participants who received information included in the “Carleton Skill Training Program” and in addition formed implementation intentions improved their (...) class='Hi'>hypnotic responsiveness as compared to all of the other three groups on measures of objective responding and involuntary responding. Thus, in line with the nonstate or cognitive social–psychological view of hypnosis stating that an individual’s hypnotic suggestibility is not dispositional but modifiable, our results suggest that hypnotic responsiveness can be heightened by furnishing hypnotic instructions with ad hoc implementation intentions.

As understood by neodissociation and sociocognitive theorists, hypnotic responses are instances of self-deception. Neodissociation theory matches the strict definition of Sackeim and Gur (1978) and sociocognitive theory matches Mele's looser definition. Recent data indicate that many hypnotized individuals deceive themselves into holding conflicting beliefs without dissociating, but others convince themselves that the suggested state of affairs is true without simultaneously holding a contrary belief.

Religious practices centered on controlled trance states, such as Siberian shamanism or North African zar, are ubiquitous, yet their characteristics vary. In particular, cross-cultural research finds that female-dominated spirit possession cults are common in stratified societies, whereas male-dominated shamanism predominates in structurally flatter cultures. Here, we present an agent-based model that explores factors, including social stratification and psychological dissociation, that may partially account for this pattern. We posit that, in more stratified societies, female agents suffer from higher levels of (...) psychosocial trauma, whereas male agents are more vulnerable in flatter societies. In societies with fewer levels of formal hierarchy, males come into informal social competition more regularly than in stratified contexts. This instability leads to a cultural feedback effect in which dissociative experiences deriving from chronic psychosocial stress become canalized into a male religious trance role. The model reproduces these patterns under plausible parameter configurations. (shrink)
