Pro Attitude and Macro-PK: A Pilot Study Using Neuro-feedback and EMG Biofeedback

LANCE STORM AND NICHOLAS R. BURNS

ABSTRACT: Using the ProComp+ neuro-feedback apparatus, intermittent feedback was given to eight participants as they performed an alternating bimodal (i.e., normal and paranormal) task, switched at irregular intervals. During normal modes, participants were required to keep EEG alpha rhythm above threshold, and/or EMG amplitude below threshold, in order to elicit positive feedback of a ‘Spinning Man’ animation. The man spun only when one or both threshold contingencies were met. During paranormal modes, regardless of alpha and/or EMG amplitudes, the participants were required to keep the man spinning, but they were blind to the fact that their attempts could only elicit micro-PK changes (i.e., ‘anomalous perturbations’) on a single frame taken from the Spinning Man animation sequence. If psi was elicited during this mode, anomalies were expected as a result of participants’ focussed attention. It was hypothesised that (i) video anomalies might occur during the paranormal modes, and (ii) EEG alpha amplitude might be higher, and/or integrated EMG amplitude might be lower, during paranormal modes. Stills of the video frame caught during paranormal modes were later analysed. No evidence was found for (i) or (ii). Three un-hypothesised ‘anomalous’ effects occurred during the running of the experiment but, on parsimonious grounds, these were attributed to software flaws. It is argued that lack of biofeedback during paranormal modes may have been psi-inhibitive. Previous meditation and biofeedback experience had no effect on EEG alpha amplitude or EMG. Some participants showed evidence of waveform training. Transliminality correlated with alpha and EMG in the directions hypothesised, but only approached significance in the Transliminality/alpha correlation.

Pueblo Parapsychology: Psi and the Longbody from the Southwest Indian Perspective

BRYAN J. WILLIAMS

ABSTRACT: The concept of the longbody traces its origin to the language and spiritual tradition of Native American tribal cultures, particularly that of the Iroquois Indians. Within these cultures, it represents a worldview quite different from that of Western cultures, in that it posits a broad degree of spiritual interconnection between all things in the natural world, living and material alike. From this view, a tribal member’s experience of self is not solely limited to their individual living body, but also includes other family and tribal members (both living and deceased), the objects they possess, and the geographical locations that they inhabit or consider sacred. These can all be seen as extensions of the individual small body and the self that, when taken as a whole, comprise the larger tribal “longbody.” The concept was first introduced to parapsychology by Christopher Aanstoos (1986), and was adopted by William Roll (1987, 1989, 2005) as a metaphorical way to understand the interconnection between mind and matter that is suggested in one form or another by all the known types of psi phenomena. The concept does not seem to be unique only to the Iroquois; several Indian tribes of the American Southwest also have aspects of their oral-based spiritual tradition that reflect something very similar to the longbody. In this paper, the similar aspects from four Southwest tribes (the Hopi, the Navajo, Laguna Pueblo, and Zuni Pueblo) are reviewed, and their implications for tribal psi experiences and Roll’s longbody hypothesis are discussed. It is suggested that tribal oral tradition, which is based in memory, opens the way for psi as a means to ensure the survival of the tribes and their respective longbodies across space-time. It is further suggested that the geophysical properties of the location of certain Pueblos and sacred tribal sites may display anomalous activity similar to that observed in investigations of reportedly haunted sites, which may aid in giving rise to tribal psi through their possible energetic effects on the brain. Possible directions for future research are also offered.

The Assumption of Grand Identity and Belief in Reincarnation

MICHAEL A. THALBOURNE

ABSTRACT: Sometimes people in psychotic episodes purport that their identity has changed, and the most famous personage to whom there is a change is Jesus Christ. Clearly, even if true, the person has not arrived on Earth by celestial spectacle, but rather by being born in the normal way. This fact suggests that such people may be more likely to believe in reincarnation. In this research project belief in reincarnation was correlated with belief that one has on at least one occasion experienced being literally a famous person, such as Jesus Christ. The evidence, using a questionnaire approach and a total of 1,025 people, is that there is a positive and significant association between the two variables, r(1023) = .083, p = .008, but it is extremely small and must therefore act in concert with other more important variables to produce the assumption of grand identity.

Casting Shadow and Light on the Peer Review Process: A Reply to Neppe’s (2007) “Interpreting Key Variables in Parapsychological Phenomenology by Single vs. Screening Questions”

CRAIG D. MURRAY AND JEZZ FOX

ABSTRACT: In the previous issue of the Australian Journal of Parapsychology [A.J.Para.], Vernon Neppe presented a critique of the use of a single item to differentiate a sample into out-of-body experients and non-experients (Neppe, 2007). Although this is a discussion generally meriting attention, Neppe’s critique is made directly in response to his experience of reviewing our earlier paper, and of its subsequent inclusion in the December 2006 issue of A.J.Para. (Murray & Fox, 2006). Indeed he states that “As a referee of that article, it has led to a crucial debate. Is this approach legitimate?” (Neppe, 2007, p. 80).

Reviewer’s Response to Neppe (2007)

JIM HOURAN

ABSTRACT: Neppe’s (2007) criticism of Murray and Fox’s (2006) “From Dreams to (Virtual) Reality: Exploring Behavioural Embodiment in Out-Of-Body Experients” is correct but somewhat misleading. That is, Neppe (2007) is absolutely correct when he states that “No matter how well a single question is fashioned it could create both false negatives and false positives due to misinterpretation” (p. 82), and he correctly notes that the use of multiple questions give greater assurance that “what is subjectively measured is as appropriate a measure of the subjective phenomenon as possible” (p. 82). In some cases a single question might well suffice (e.g., “Did you ever get legally married?”), whereas establishing the presence of Out-of-Body Experiences might indeed require more than one question.

Peer Review and Phenomenological Analyses in Research

VERNON M. NEPPE

ABSTRACT: I was asked by the editor to contribute a response to Murray and Fox (2007) whose scientific work I respect. I comment on two issues: Peer review and phenomenology. Peer review is important. The object is to improve the quality of the submitted article and the quality of the current research and sometimes impact on future studies. Peer reviewers should not be regarded as the only experts. They are there to assist having been selected generally because, like the submitting authors, they, too, have expert knowledge in that discipline. Peer review optimally assists the authors in improving articles and their future research. Refereeing processes are not intended to be rewrites of articles. Certain interchanges in the review process are made available to authors, others only to the editor himself.

Science, Nonscience and Rejected Knowledge: The Case of Parapsychology

HARVEY J. IRWIN

ABSTRACT: Parapsychologists purport to apply scientific method to the investigation of the bases of commonly reported parapsychological experiences such as extrasensory perception. Despite over a hundred years of associated research effort the status of parapsychology as a scientific endeavour is disputed by a substantial section of the contemporary mainstream scientific community. This paper identifies some of the major chronological shifts in the rationale for dismissing parapsychology as nonscientific, examining several historical attempts by parapsychologists to establish the scientific legitimacy of their discipline and the concomitant strategies of orthodox scientists to marginalise the findings of parapsychological research as rejected knowledge.

Does Your Animal Know You Are Going Out? A Survey in Portugal about Belief in Psychic Pets

S. N. RAZENTE, C. SILVA, AND C. LOBO

ABSTRACT: Research was conducted on the relations between humans and animals to find out about animal behaviour and the types of beliefs associated with it. A survey in the form of personal interviews was carried out between February and March 2000, and comprised 1014 participants from five different regions of Portugal. R. Sheldrake’s (Brown & Sheldrake, 1998) questionnaire was used to examine pet owners’ beliefs about “psychic experiences” and the behaviour of their animals. Results showed that the majority of participants: (1) don’t agree that their pets get agitated before a family member arrives home, (2) recognise that their animals know they’re going to leave, and (3) disagree that their pets respond to their thoughts or silent commands. We advance the hypothesis that biases in environmental stimuli explain these alleged psychic experiences between owners and their pets.

Psi, Divination and Astrology: A Brief Introduction

LANCE STORM

ABSTRACT: Since it is alleged that astrology provides a method of gaining information about the personality of an individual, that might include advice and forecasts about future actions, the possibility exists that astrology depends on an anomalous process—a process that takes place outside the human brain, but nonetheless affects the human brain in ways so far undetermined. This short article is an introduction to the idea that ESP and astrology may be related.

Hopeful Findings, Unduly Neglected, on Stars and Human Affairs

SUITBERT ERTEL

ABSTRACT: In one of his careful astro-statistical studies, Arno Müller and Günter Menzer (1993) reported correlations between infants’ deaths in families of German nobles and Saturn positions at the infants’ birth hours. This result went unnoticed. Another neglected result of a well-controlled study is that of Timm and Köberl (1986) on astrologers. These major authors admitted that their participants’ interpretations of horoscopes were better than chance. They deemed this success due to paranormal (psi) effects. A recent case study on an astrologer’s efficiency at chart interpretation lead me to suspect that here, too, psi might be involved. Emergent phenomena like these should be taken as a challenge for further research.

Comment on Ertel (2007): Hopeful Findings Unduly Neglected

GRAHAM DOUGLAS

ABSTRACT: I am prompted to comment on some issues raised by Suitbert Ertel’s 2004 paper reprinted in Australian Journal of Parapsychology (Ertel, 2007). The first of his hopeful findings raises the question of a physical mechanism for parapsychological effects in general, an issue to which Spottiswoode (1997) and May (2001) have attached great importance. While looking at possible geophysical mechanisms we should not forget the equal need for a neurochemical pathway to explain such phenomena.

Planetary Effects and Psi, Related Through Geo- and Bio-Mechanisms? A Reply to Douglas (2007)

SUITBERT ERTEL

ABSTRACT: Speculations about mechanisms as expounded by Douglas (2007) are encouraging, but they also need to be thought over carefully and run through the appropriate tests. A connection between Gauquelin-type correlations of “neo-astrology” (Gauquelin, 1988) and Chizhevsky-type correlations of “helio-biology” (Chizhevsky, 1971) may exist. Neo-astrological correlations manifest themselves with birth peaks of eminent professionals after the rise or culmination of Mars (e.g., athletes), Jupiter (e.g., actors), and Saturn (e.g., physicians). Helio-biological correlations appear with peaks of social unrest and cultural-political revolutions during periods of high sunspot activity. I found sufficient evidence for neo-astrological (Ertel & Irving, 1996) as well as for helio-biological correlations (Ertel, 1996, 1997). But to my disappointment, I missed a connection between the two. Between the planetary and the solar or correlated geomagnetic processes no connection could be unearthed (Ertel, 1989).

Research Note: Interpreting Key Variables in Parapsychological Phenomenology by Single vs. Screening Questions

VERNON M. NEPPE

ABSTRACT: The article by Craig Murray and Jezz Fox (2006)—”From Dreams to (Virtual) Reality: Exploring Behavioural Embodiment in Out-Of-Body Experients”—is an example of how one question alone has been used for studying a key variable in parapsychological research. As a referee for that article, it has led to a crucial debate. Is this approach legitimate? More powerful would be a series of questions to establish whether the subjects’ experiences purport to what it should, and if it does not, to be able to establish why not.

Reincarnation Beliefs of the Gumini People of the Simbu Province of Papua New Guinea

JOAN D. JOHNSTONE

ABSTRACT: This article describes the traditional reincarnation belief system of the Guminis, a small group of people living in the southeast of the Simbu Province of the Highlands of Papua New Guinea. This system embraces the belief that the spirit of some humans is, after death, reincarnated within the body of another living person of similar age and probably of the same sex as the deceased. This person, a stranger, then represents the continuation of the life of the person who died in terms of his/her social and kinship relationships. It is demonstrated that this belief system was functional in traditional Gumini society, but may not continue to be so in future due to rapid changes in rural and urban life currently affecting the people of Papua New Guinea.

From Dreams to (Virtual) Reality: Exploring Behavioural Embodiment in Out-Of-Body Experients

CRAIG D. MURRAY and JEZZ FOX

ABSTRACT: Recent research has indicated that the body experience of people who report a prior out-of-body experience (OBErs) is qualitatively different on a number of body-image variables to that of non-experients (non-OBErs). The present study examined OBErs and non-OBErs Behavioural Embodiment during immersion in a Virtual Reality system. It was hypothesised that OBErs would, compared with non-OBErs, exhibit a disembodied behavioural interaction with the Virtual Environment (VE), characterised by the proportion of time spent navigating the environment from an elevated position and the number of collisions with virtual objects. It was also hypothesised that OBErs would score higher on measures of absorption, dissociation and somatoform dissociation. There were no significant differences between OBErs (n = 16) and non-OBErs (n = 28) on Behavioural Embodiment (i.e., the proportion of time spent navigating the environment from an elevated position and the number of collisions with virtual objects), although there was a positive correlation with number of OBEs and proportion of trial time spent navigating the environment from an elevated position. OBErs were found to score significantly higher than the non-OBErs on measures of absorption, dissociation and somatoform dissociation.

Meta-Analysis in Parapsychology: II. Psi Domains other than Ganzfeld

LANCE STORM

ABSTRACT: The present article completes the two-part review on meta-analyses in parapsychology (for Part I, see L. Storm, 2006). The reviewed literature other than ganzfeld/autoganzfeld studies, includes meta-analyses on: (i) biological systems (DMILS), (ii) forced-choice ESP, (iii) free-response ESP, (iv) dice-throwing, (v) micro-PK (RNG), and (vi) dream-psi. Meta-analyses by T. R. Lawrence (1993), E. Haraldsson (1993), and R. G. Stanford and A. G. Stein (1994) are also reviewed. Results indicate that these meta-analyses provide considerable evidence that there is an anomalous effect in the field of parapsychology in need of an explanation. It is concluded that these and other meta-analyses in parapsychology have revealed significant non-zero effects across studies, although these tend to be rather small, but process-oriented research will further our understanding of these anomalies.

Belief in, and Alleged Experience of, the Paranormal in the Portuguese Population

MICHAEL A. THALBOURNE, C. F. SILVA and S. N. RAZENTE

ABSTRACT: Belief in, and alleged experience of, the paranormal in the Portuguese population were gauged via a random telephone survey of 750 persons, using a Portuguese version of the 18-item forced-choice Australian Sheep-Goat Scale (Thalbourne, 1995).  Belief and experience tended to be on the low side, as shown both by the low average scores obtained for each of the 18 individual items and by the tendency of Scale-scores to occur at the low end of the range. There were significant and moderate correlations with selected other variables such as belief in reincarnation and claimed recall of a previous life, and significant but rather weak correlations with belief in astrology and religious variables.

ESP under the Ganzfeld, in Contrast with the Induction of Relaxation as a Psi-Conducive State

ALEJANDRO PARRA and JORGE VILLANUEVA

ABSTRACT: Ganzfeld stimulation is associated with an increase in attention to internal imagery. Investigators have suggested the association with a view to developing an “experimental hypnagogic” technique in order to facilitate the study of hypnagogic imagery. The present experiment uses a telepathy-focused, non-ganzfeld condition, the findings of which were compared to the ganzfeld technique, in counter-balanced order. One hundred and thirty-eight participants attended two GESP trials at the Institute for Paranormal Psychology, in Buenos Aires. The majority of the participants (93.5%) reported previous personal experiences suggestive of psi. The first author was the experimenter and the second author was the sender for the entire sample. Two questionnaires were administered before, and one after, the ganzfeld session, to evaluate mental activity, bodily changes, pleasant experiences, and change in state of awareness. A CD-R containing 3,500 high-resolution colour pictures was used to provide image-targets. We would conclude that this experiment offered some support to the claim that ganzfeld stimulation is psi-conducive, to the extent that there was a significant difference between the two test conditions, in a direction favouring the ganzfeld condition. Expected percentage of hits was 25%. The ganzfeld gave 41.3% hits, p < .001, the non-ganzfeld 27.5%, and the difference between the two conditions was also significant, p = .016. No relationship was found between prior psi experiences and ESP scores. Nevertheless, we did not conclude that the “good” ESP results using ganzfeld were related to a modified state of consciousness because these results might depend upon other variables independent of the non-ordinary state.

Research Note: A Statistical Test of the ‘Library Angel’

MICHAEL A. THALBOURNE

ABSTRACT: The term “Library Angel” was apparently coined by Arthur Koestler (Hardy, Harvie & Koestler, 1973, pp. 161-166). It is a coincidence “where a combination of serendipity and intuition appears to be operating to find [exceedingly relevant] books or source references” (Inglis, 1990, p. 8). Jane Henry (1993) gives a slightly different interpretation: “for example, after searching high and low for a reference one gives up, only to find that it ‘magically’ appears, perhaps falling off a shelf in front of one” (p. 98). I shall give the reader a personal example from my 1997 collection of book coincidences on the Internet entitled Bridge.

A Discussion of the Evidence that Personal Consciousness Persists After Death with Special Reference to Poltergeist Phenomena

WILLIAM ROLL

ABSTRACT: Humans have a dual mind, the mind of the left hemisphere and the mind of the right hemisphere. The left hemisphere has an organ for language and when awake can be conscious of things with linguistic labels. The right hemisphere is good at operating with mental images as in dreams. The functions of the right hemisphere include extrasensory perception and psychokinesis. However, the findings that have been advanced in favour of the idea that personality survives death have mostly been discussed in terms of the continuation of the left mind. This paper explores the pro and cons of this approach.

Human Levitation

SIMON HARVEY-WILSON

ABSTRACT: Human levitation occurs when the physical body rises into the air seemingly in defiance of the force of gravity. Traditionally most levitation reports have originated from seven groups: (i) mysticism, (ii) shamanism, (iii) people supposedly possessed by demonic spiritual entities, (iv) those subjected to poltergeist activity, (v) Spiritualism, (vi) people who believe they have been abducted by aliens, and (vii) martial arts such as qigong. So far almost no scientific research appears to have been conducted into this phenomenon. In order to persuade empirical scientists that human levitation warrants further investigation, this qualitative study contains two components. First, there is a thematic comparison of historical and modern levitation reports from the seven groups to see what physical, cultural and phenomenological circumstances they may have in common. Three kinds of evidence have been examined: general features of the seven groups; interviews with a sample of Christian priests and pastors, Spiritualists and qigong instructors; and interviews with six people who claim to have levitated. Second, to assist future researchers in their investigations, the present article includes a hypothesis-generating exercise that seeks clues from the thematic comparison and interviews as to how human levitation might work.

Meta-Analysis in Parapsychology: I. The Ganzfeld Domain

LANCE STORM

ABSTRACT: The present article is a review of the ganzfeld meta-analytic literature. It is found that significant results were obtained in all but one ganzfeld meta-analysis - that of J. Milton and R. Wiseman (1999). However, with combinatorial re-construction of the available databases and the uncovering of 11 studies overlooked by Milton and Wiseman, L. Storm and S. Ertel (2001) reconfirmed that the ganzfeld was still the paradigm that delivered one of the highest effect sizes of all the experimental domains in parapsychology. More recent studies support this finding. Parapsychologist and pioneer of ganzfeld research, Charles Honorton (Honorton, 1985) said that the ganzfeld demonstrates a “significant psi effect” (p. 81), and the evidence in the present article supports that claim.

Quasi-Experimental Study of Transliminality, Vibrotactile Thresholds, and Performance Speed

JAMES HOURAN, LARRY F. HUGHES, MICHAEL A. THALBOURNE, and PETER S. DELIN

ABSTRACT: Transliminality has been hypothesised to derive from weak or erratic cognitive mechanisms that are responsible for the active suppression (or gating) of irrelevant information from consciousness. It was therefore expected in a test of vibrotactile sensitivity that (i) individuals with high transliminality scores (HT) have lower thresholds than individuals with low transliminality scores (LT), (ii) the HT group take less time than the LT group to obtain a threshold, (iii) and the presence of a stimulus that competes for attention increases the time and thresholds of the HT group to a greater extent than those of the LT group. Fifty participants (17 HTs, 33 LTs) completed three repetitions of threshold testing using the CASE IV System while exposed to each of four competing auditory conditions (two Intensity x two Complexity). Results confirmed predictions, but only the intensity of the competing stimulus, rather than its relative complexity, interfered with the vibrotactile thresholds of the HT group.

The Marriage of Parapsychology and Normal Psychology

Michael A. Thalbourne

ABSTRACT: I would like to begin by sharing with you an anecdote—in fact a coincidence.  Unfortunately I have no dates for the two halves of this coincidence, but let that not cause us to dismiss it out of hand.  Thus, it was some years ago that I happened to wonder to myself at one time the strange thought of whether a decapitated head continued to have consciousness for a while.  It so happened that, at the time, I was reading the beginning of Nandor Fodor’s (1966) An Encyclopaedia of Psychic Science, scouring it for terms that I might include in my second edition A Glossary of Terms Used in Parapsychology. I recall that I did not advance very far into this book, but came at length to the entry under “Community of Sensation”, an old expression used in hypnosis to refer to a sort of sensory telepathy between hypnotist and subject, or, as we shall see, between the subject and another person.  And almost before I realised it, there was the following text as a bizarre example of community of sensation.

Chemical Induction of Precognitive Dreams

F. de Pablos

ABSTRACT: Rivastigmine, a potent partially reversible Acetylcholinesterase inhibitor used in the treatment of Alzheimer Disease, enhances both memory and REM sleep. It has been postulated that besides those normal properties it could also favour retrograde dream formation, i.e., precognitive dreaming.  An experiment was carried out with 10 normal participants, in a double blind design - five participants ingested 0.3 mg of Rivastigmine and five participants were on Placebo - over a period of ten consecutive nights. Participants recorded the dreams that they had during those nights. They were also instructed to write a life event protocol containing significant daily events. A longitudinal matching design between dreams and future daily events allowed the researcher to find positive matches between dreams and life-events that could be regarded as indicating precognition. Data comparison between the Rivastigmine and Placebo groups yielded two significant effects: (1) Rivastigmine increased dream productivity as measured by the number of dreaming episodes; (2) Rivastigmine increased precognitive dreaming as measured by the number of dream/future-event matches.

Psi Test Feats Achieved Alone at Home: Do they Disappear under Lab Control?

Suitbert Ertel

ABSTRACT: Extraordinary hit-rates from multiple-choice tests, obtained by participants alone in their homes, are ambiguous. On the one hand, their feats might in fact reflect psi power manifesting itself better under informal home than under formal lab conditions. Yet hit surpluses obtained without lab control might also be due to negligent or fraudulent conduct. One way out of this dilemma is to let participants run psi tests at home and to invite high scorers thereafter to do additional runs under lab control. This strategy has been endorsed using N = 238 (Sample 1) and N = 47 (Sample 2) of student participants. Sample 1 took the ball-selection test (version I). Fifty numbered table tennis balls (10 of each, numbered 1 to 5) are drawn from an opaque bag. Participants guess and draw out numbered balls blind, recording the data as they go (PMCE = 0.20). Participants put drawn balls back into the bag and they shake the bag prior to each trial. One test unit consisted of six or eight runs comprising 60 trials each (total: 360 or 480 trials). Sixteen high scoring participants of Sample 1 were also tested under lab control, again using ball test procedure (version I). Sample 2 took the ball-selection test (version II). This test resembles ball test I in almost every respect except that green or red dots are sprinkled over the balls, and participants guess numbers (five targets) and colours (two targets; MCE = 10%). Thirteen high-scorers of Sample 2 were also tested under lab control using the bead-selection test where each participant draws one of five colours (no numbers, MCE = 0.20). It was hypothesised that (i) hit-rates of high scorers in home tests decline (due to less psi-conducive conditions under lab control and regression towards the mean), and (ii) hit-rates of high scorers under lab control are still significantly above chance (due to genuine psi as was effective at home). Both hypotheses were confirmed with Sample 1 and replicated with Sample 2. Three participants obtained significantly higher hit-rates under lab control compared with their home performance. The issue of fraud and bias loses relevance in view of such findings. It is recommended that the first-home-then-lab-test strategy be introduced into parapsychological research on a broader scale.

Perceptual and Memory Capabilities of Witnesses to Anomalous Visual Phenomena

B. F. DEAR and A. L. JINKS

ABSTRACT: The perceptual and memory capabilities of witnesses to anomalous visual phenomena (AVP) were examined in four experiments. Experiments 1 and 2 tested witnesses’ abilities to access explicit and implicit memory, Experiment 3 explored witnesses’ abilities to discriminate between genuine and abstract objects, and Experiment 4 examined witnesses’ propensity to misidentify fragmented objects. No differences were found between witnesses and non-witnesses on any task. Nevertheless, a number of medium-and large-sized effects emerged. Together, these suggested that had power been greater, witnesses would have been shown to (1) require less time than non-witnesses to recall specific memories, (2) be more likely to identify abstract objects as legitimate, (3) require fewer presentations to identify fragmented and ambiguous objects and (4) be more likely to misidentify these same objects. Some evidence was also produced to suggest witnesses may actually outperform non-witnesses on the implicit memory task. Overall, the findings provide weak support for the involvement of perceptual and memory variables in the perception of AVP.

A New Theory on Place Memory

PAMELA RAE HEATH

ABSTRACT: Place memory appears to involve the storage of information by the environment, which can be retrieved through paranormal means. This concept has been around since the inception of parapsychology. In recent years, it has been generally accepted that it is the living, not the dead, that appear somehow to be involved in the creation of place memory. Unfortunately, although some theories have been proposed for how place memory works, none of them are definitive. Heath (2004) recently proposed that it might aid our understanding of the phenomenon to consider the possibility that there may be two ways by which place memory is created - one active, through psychokinesis, and the other ‘passive,’ occurring more often with proximity, recency, and frequency of repetition. The theory is discussed that resonance might be the mechanism of action for the creation of ‘passive’ place memory. Furthermore, recent advances in physics would suggest that this information, regardless of its method of creation, might not require any special “psi-field,” but could be stored via the configuration of the atomic electron cloud and the geometric structure of molecules, including water.

Automatic Writing Revisited

SUSAN B. MARTINEZ

ABSTRACT: The topic of automatic writing immediately elicits the question: Discarnate authorship or “subconscious imagination”? The present essay argues that the Oahspe bible, for which Dr. John Ballou Newbrough (JBN) stood as “amanuensis”, could not have been written by a mortal mind, but only by human hands acting as instrument of a higher power. Newbrough’s own descriptions of the experience (the speed of the typing, the veritable army of communicators, etc.) may help the student sort out the real from the imagined prodigy. And although classed as mental mediumship, the event was arguably telekinetic. The doctor, however, had to undergo ten years of study and discipline to bar the influence of his own thinking, followed by another ten years’ training and purification to sharpen his “etheric” sight and perceptiveness. The writing was done each day at dawn, that early hour selected as the most propitious time for clairvoyance.

The Possible Role of Psychokinesis in Place Memory

PAMELA RAE HEATH

ABSTRACT: The idea that the environment can store recordings made by living beings - also known as place memory - has been around for over a century. This paper reviews how the term ‘place memory’ has changed since it was first used by parapsychologists. It also considers what the research literature says regarding the recording and retrieval of place memory, and suggests that there may be more than one way in which information can be recorded by, or imprinted upon, the environment. The hypothesis is discussed that psychokinesis might be involved in some of these cases, particularly when stress or peak levels of emotion are involved, as is often the case in crisis situations.

Avoiding the Intervention Paradox

COLIN MITCHELL

ABSTRACT: The author aims to show that there are possible models of time for which the Intervention Paradox is not a barrier to the possible existence of a type of precognition in which the event precognised is avoided or changed. Two different configurations of the ‘block model’ of space-time are used to show how this could be done: one with multiple futures and one with another time dimension.

Mania and its Relationship to the Sheep-Goat Variable

MICHAEL A. THALBOURNE

ABSTRACT: In this study the focus was on the correlations between belief in, and alleged experience of, the paranormal (the so-called sheep-goat variable) and measures of hypomania and of mania. In all 4 analyses examined sheep were significantly more hypomanic than goats, and in 7 out of 10 significantly more manic. Mental health implications are discussed.

Are Musical Themes Better than Visual Images as ESP-Targets? An Experimental Study Using the Ganzfeld Technique

ALEJANDRO PARRA and JORGE VILLANUEVA

ABSTRACT: The ability to detect emotion in music has many educational and practical benefits. However, there appear to be few studies reported in the literature in which sounds have been used as stimuli in extrasensory tests. The present study was undertaken in order to compare auditory with visual stimuli and to explore whether psychological factors which appear to be favourable in music tests are related to ESP. Musical styles were chosen as targets in this experiment. Fifty-four participants attended two GESP sessions (each on a different occasion) at the Institute of Paranormal Psychology in Buenos Aires, Argentina. The first author (AP) was the experimenter, who received each participant, and the second author (JV) was the blind “sender” for all of the sample. A CD-R containing 3,500 high-resolution colour pictures and another CD containing 112 themes in MP3 format were used, on the two different occasions.

People Who Remember Things They Never Learned

KEITH CHANDLER

ABSTRACT: Explaining the unique skills of so-called “idiot savants,” now generally referred to simply as savants, has long puzzled psychologists. Savant Syndrome combines various brain pathologies with highly sophisticated behavioural abilities in such areas as graphic art and musical performance. As a mental realist, I contend that no view of memory or behaviour based on physical realist views can account for Savant Syndrome. I argue that it is related to other “structural” phenomena such as biological morphogenesis, the transmission of Jungian archetypes, and cognitive and sensory “formation rules” because all these classes of phenomena depend on the brain/body’s access to configurations in their respective universal field levels. For mental realism, all such levels derive from the Cosmogenic Field, the “first” (ontologically speaking) emanation of Cosmic Thought in mental realist ontology. While each of us has his or her own idiosyncratic set of modulations relative to the cerebral field level of the Cosmogenic Field, every human being also has access to a priori structural organizing patterns introduced in our phylogenetic and cultural heritage. Behavioural as well as cognitive skills depend on such a priori structures. Savant Syndrome is thus explained as a sharing of or participation in field memories of advanced behavioural skills.

The Concept of Coincidence

PETER. S. DELIN

ABSTRACT: This paper analyses the concept of coincidence as it is applied in everyday life, and examines the processes whereby we come to feel that some coincidences are “extraordinary”, or “remarkable.” It does so by pointing out, examining and illustrating three different senses of the word “coincidence.” The first, coincidence in sense A, is coincidence as a description of a situation or set of events, prior to any question of whether this outcome has arisen by chance, or through some as yet unidentified causal agency. Thus, we may suggest it is a “coincidence” that Kennedy’s secretary was called Lincoln, while Lincoln’s secretary was called Kennedy. The second sense, coincidence in sense B, is the one we invoke when we say such things as “it’s only a coincidence,” or “it was purely coincidental.” What we are doing is to accept that a coincidence in sense A has occurred, but to deny that any causal explanation for its occurrence is either necessary or appropriate. Coincidence in sense B, then, is coincidence in sense A arising by some chance process. Finally, coincidence in sense C is the sense of “coincidence” we are usually using when we say things like “It’s a very remarkable coincidence,” or “What an extraordinary coincidence!” Hovering in the background is the notion that it needs explanation in some causal or quasi-causal way; in other words that it is not a coincidence in sense B. We may even say something like “That can’t be just a coincidence!” In this paper, these three senses of coincidence are invoked in order to show that many of the events we think of as remarkable coincidences in sense C may not be quite as remarkable as we feel they are.

Harvey J. Irwin’s Introduction to parapsychology (3rd edition): A Reinterpretation in Terms of the Theory of Psychopraxia

MICHAEL A. THALBOURNE

ABSTRACT: One of the best, perhaps the best, textbooks of parapsychology is currently Harvey J. Irwin’s Introduction to Parapsychology (3rd edition). In this book Irwin uses as key concepts extrasensory perception (ESP) and psychokinesis (PK). The theory of psychopraxia (“the self accomplishing goals”) does not make use of these terms, considering instead the endosomatic functions (within the mind-body complex) and exosomatic functions (outside the mind-body complex) of a unitary principle called psychopraxia. In this article the author attempts to redescribe parapsychology in terms of psychopraxia instead of ESP and PK, using Irwin’s book as a vehicle for the reinterpretation.

The John Edward Phenomenon “I Want To Believe”

SUE-ELLEN KJELDAL

ABSTRACT: Much international interest has been generated by psychics such as John Edward who purport to communicate with the deceased. In this article, contemporary decision theory is used as a possible explanatory factor in determining why individuals unquestioningly believe this notion, whilst empirical support against the theory appears overwhelmingly negative at this stage in research into this phenomenon.

The I Ching and the Lotto Game: Trying to Beat the Odds Using an Ancient Chinese System of Divination

LANCE STORM

ABSTRACT: The I Ching (or Book of Changes) is an ancient Chinese form of divination. A numbered hexagram (or six-line symbol) and its associated reading or forecast, is generated using the modern ‘coin-throwing’ method (three coins are thrown, six times). In the present study, the coin-throwing method was adopted for the sole purpose of establishing a consistent means of generating ‘lucky’ numbers to be used in a form of gambling known as ‘Lotto’-a televised game in which eight ping-pong balls with winning numbers printed on them are drawn every Saturday night from a pool of 45 such balls. Participants in the present study took turns throwing coins to generate their own hexagram numbers. A total of eight numbers were entered for each Lotto game. Over a period of months, ten games were played. Half the games played (5 games) independently produced significant amounts of winning numbers (p < .05). Individual hit-rates for key players ranged from approximately 17% up to 36% over the ten games. It was concluded that such high success rates might bode well for the system, but a ‘control’ condition would be necessary in a replication study to confirm the viability of the procedure.

Personality Factors and Psi-Ganzfeld Sessions: A Replication and Extension

ALEJANDRO PARRA and JORGE VILLANUEVA

ABSTRACT: This is a report of a study of the relationship between personality factors and ESP scores obtained using the ganzfeld technique, which has had a modest but consistent number of successes in various laboratories. Eysenck’s (1967) linking of extraversion and arousal was deemed potentially important to ESP performance. The relationship between ESP performance and individual differences and several personality dimensions have been studied, according to Honorton’s model which predicts the personality characteristics of successful ganzfeld participants. One hundred and thirty-eight participants attended one ganzfeld session (telepathy-focused) at the Institute of Paranormal Psychology, Argentina. The first author (AP) was the experimenter, who received each participant, and the second author (JV) was sender for each participant. Two personality inventories (the Eysenck Personality Inventory and the Sixteen Personality Factor Questionnaire) were administered before each ganzfeld session. Overall results of this experi­ment offered some four personality profiles that arise from a combination of N and E scores. Though this study did not show significant results relating direct hits to E or N scores or the 16PF factors, they were found for sanguine females and choleric male subjects. Cholerics obtained more hits than did melancholics.

“Are you there, Spenser?” Attempts at ‘PK by Committee’ in a Séance-like Situation

LANCE STORM and COLIN MITCHELL

ABSTRACT: The term PK by committee refers to a group psi effect that was hypothesised by D. Scott Rogo (1986) as being more consistent than a psi effect produced by an individual psychic. The Philip group (Toronto, Canada), formed by I. M. Owen with M. Sparrow (1976), was essentially a ‘committee’ of individuals attempting to elicit PK effects. The Philip group inspired the formation of the Spenser group (Adelaide, South Australia), which was comprised initially of a team of eight professional and amateur paranormal investigators. The Spenser group attempted to generate a fictional entity, the sea captain Spenser Blake (1770-1850), with whom conversation was attempted. No visual manifestations of Spenser were sought or produced. Spenser group sitters’ attempts at table-tilting and table levitation met with failure. Doubt remains over the cause of some rapping and scratching sounds. Attempts at influencing a candle-flame psychokinetically produced a statistically significant effect. The more salient anomalous effects produced across a series of 27 sittings are reported and attempts to explain them in rational terms are presented.

Temporal Lobe Lability and Self-Reported Haunting Type Experiences: A Questionnaire Study with an Undergraduate Sample

DEVIN TERHUNE

ABSTRACT: This study examined the hypothesis that self-reported haunting type experiences are positively associated with the temporal lobe lability of the experient. Sixty-two participants completed a brief personal history questionnaire about brain trauma and drug usage, the Temporal Lobe Dysfunction Scale, and the Haunting Type Experiences Index. As expected, temporal lobe scores were positively correlated with haunting type experience scores, r(62) = .45, p < .001. High temporal lobe scorers also scored significantly higher on the Haunting Type Experiences Index than low temporal lobe scorers, t(60) = 4.27, p < .001. Brain trauma and drug usage showed no significant relationship to temporal lobe scores or haunting type experience scores. Exploratory analyses found that sub-samples, defined by gender and program of study (Fine Arts or Psychology), scored comparably on the Temporal Lobe Dysfunction Scale and the Haunting Type Experiences Index. The present results conceptually replicate previous research linking temporal lobe symptomatology and haunting type experiences, but further research is warranted given the methodological confounds in the present study.

“Out-of-Body Experiences” (OBEs) and Brain Localisation. A Perspective

VERNON M. NEPPE

ABSTRACT: Blanke et al. reported in Nature magazine how stimulating the right angular gyrus in a patient with a right temporal seizure focus with a 4mA or 5mA current, produced transitory out-of-body experiences (OBEs) involving seeing either legs or arms disappearing when she attempted to “inspect the illusory body or body part.” Despite their reporting that changes in visual attention and/or current amplitude in the angular gyrus could explain the “phenomenological modification”, this finding produced significant press interest, as a site for the OBE was postulated. This brief paper puts this and similar findings into perspective:

  1. The OBE described appears atypical for the type of subjective OBE described by Subjective Paranormal Experients (SPEs).

  2. The likely pathological angular gyrus in this patient cannot be compared with that area in normal individuals.

  3. Generalisation of this one case to other humans is not warranted.

  4. Additionally, a previous second case suggests more than one locality for provoking an OBE by electrocortical stimulation. When analysing comparable phenomena such as déjà vu and memory, no single localisation can be found.

  5. Even when findings on subjective paranormal experiences (SPEs) including OBEs are referable to specific anomalous brain functioning, they neither confirm nor deny the veridicality of the SPEs. These may have endogenous origins within the brain like pathological hallucinations do; or a particular brain function pattern may allow experience of an outside, usually covert, reality.

  6. At least four distinct nosological subtypes of déjà vu exist. Similar research on OBEs needs to be performed to demonstrate the likely subtypes that exist.

Methodologically, associative links do not imply causality. To consolidate the causality hypothesis, one should analyse SPEs and also the converse, like temporal lobe epileptic subjects. The reductionistic fallacy of OBEs being fully explained purely on the basis of stimulating a specific area of the brain is not tenable.

Analysis of Haunt Experiences at a Historical Illinois Landmark

JAMES HOURAN

ABSTRACT: Previous questionnaire and field research shows that the report and phenomenology of haunt experiences correlate with a number of perceptual-personality variables, suggesting that processes related to a shifting and focusing of attention mediate who will have an experience and who will not. There is additional evidence to suggest that Psychological Experiences and the perception of Physical Manifestations in haunts are mediated by different perceptual-personality variables. An investigation of a reported haunt at a historic mansion was conducted to conceptually replicate these findings, as well as to determine the relation of haunt experiences to aesthetic and environmental factors at the site. Twenty ‘experimentally-blind’ participants completed a battery of psychological measures and then visited three target and seven control areas. For each area, participants documented any anomalies they experienced on a checklist. The location of participants’ experiences corroborated independent witness accounts at the site, although participants also reported experiences at control areas. Consistent with earlier findings, the number of discrete experiences and the number of different categories of experience both correlated strongly with Participant Expectation and Traditional Paranormal Beliefs. However, Psychological Experiences and Physical Manifestations were not mediated by different sets of psychological factors. Basic features of the test areas showed no association with the cumulative pattern of participants’ reports. The probability of having a haunt experience might therefore derive from a noise-to-signal ratio. In this sense, perceptual-personality variables merely facilitate the perception of stimuli that produce haunt experiences, rather than inspiring witness reports. The haunt stimuli themselves in this case remain unidentified, but seem to be distributed probabilistically throughout the site.

Belief in, and Alleged Experience of, the Paranormal in Ostensible UFO Abductees

KEITH BASTERFIELD and MICHAEL A. THALBOURNE

ABSTRACT: It has often been asserted anecdotally that the UFO phenomenon is associated with reports of the paranormal. Thus far a statistical study has not been conducted. In the present research, a measure of belief in and alleged experience of the paranormal - the 18-item forced-choice Australian Sheep-Goat Scale - was administered to 21 self-selected ostensible UFO abductees and their responses com-pared with those of a control group - 301 students. It was found that abductees reported significantly greater belief in, and alleged experience of, the paranormal (ESP, PK and life after death). The anecdotal reports were thus confirmed. However, it should not be concluded until more research is carried out that the abductees are necessarily more psychic.

Is Scientific Investigation of Postmortem Survival an Anachronism? The Demise of the Survival Hypothesis

HARVEY IRWIN

ABSTRACT: The survival hypothesis, or the notion of postmortem survival, has been a key domain of parapsychological research since the inception of the Society for Psychical Research in the late nineteenth century. Parapsychologists nevertheless have made no definitive progress toward the verification of the survival hypothesis, and the continued centrality of this issue to parapsychology is a major impediment to the acceptance of the field as a scientific enterprise. A redefinition of parapsychology and the relegation of the survival hypothesis to minor status are advocated.

Scepticism and Credulity

PETER S. DELIN

ABSTRACT: Though scientific thinking has been in vogue since the seventeenth century, it represents only a minority view, and is essentially sceptical. The majority of mankind adopts a credulous attitude towards natural phenomena. The extremely sceptical and the extremely credulous have many psychological characteristics in common and both may be unreliable in assessing occasional phenomena.

Examining Macro-Psychokinetic Experiments

M. WILLIAMS and R. LANG

ABSTRACT: This paper deals with a method of creating macro-PK results in a replicable format. The methodology is referred to as “table-tilting”, though in older literature it may also be called “table-moving”. We present the information in two parts: the first part deals with a brief history of the phenomena, whilst the second part deals with our own experiments. Rather than simply give our opinion on some of the original experiments, we will give the verbatim accounts presented in the various literature of the time.

A Parapsychological Investigation of the I Ching: Seeking Psi in an Ancient Chinese System of Divination

LANCE STORM

ABSTRACT: The Chinese book of divination, the I Ching, has been used in two studies that featured an unorthodox use of the system (L. Storm & M. A. Thalbourne, 1998-1999, 2001a). Both studies (N1 = 93; N2 = 107), tested participants on 2 paranormal tasks using 3 coins: (a) generation of a hexagram (a six-line symbol with associated reading or ‘fortune’), and (b) generation of changing lines (gained by throwing 3-of-a-kind using 3 coins). The hexagram hit-rates (i.e., ‘hitting’) in both studies were significantly above chance, but the number of changing lines in both studies was not. In Storm and Thalbourne’s (1998-1999) initial study, a number of significant parapsychological correlations were found, but in Storm and Thalbourne’s (2001a) second study none of these correlations replicated. In a re-analysis of the data (see Storm & Thalbourne, 2001b), the 2 samples were pooled to form a larger sample (N1+N2 = 200). There was a return to significance in all but one correlation. Psychological correlations of transliminality with each of four 16PF factors replicated. The present article describes a third I Ching study using University of Adelaide psychology II students (N3 = 43) who took part in a practical in their psychology course. There were no significant paranormal findings, but 5 psychological correlations replicated for a third time. Pooling the new data with the earlier larger sample (N1+N2 = 200) and subsequent re-analysis of that data (N1+N2+N3 = 243) showed a return to significant results in virtually all tests.

Shamanism and Alien Abductions: A Comparative Study

SIMON HARVEY-WILSON

ABSTRACT: Some UFO researchers (ufologists) claim that being abducted by aliens can be compared with shamanic initiation experiences in traditional societies in that both types of experience may be similarly transformative, leading to a more spiritual or animistic world-view, a deep concern for the environment and the development of paranormal abilities such as healing. This qualitative study was designed to test the validity of such claims by investigating whether the experiences and subsequent world-view of eleven alien abductees (eight women and three men) from a Western Australian abduction support group were similar to those of the typical shaman. To do this, material gathered from in-depth interviews with the abductees was compared with the anthropological literature on shamanism, especially shamanic initiation experiences, from various parts of the world.

Examining the Evidence for Psi in the Context of Scientific Revolution

HANNAH JENKINS

ABSTRACT: This paper is concerned with the representation of psi in current philosophy texts. It undertakes an analysis of the current status of evidence for psi according to a Kuhnian scientific revolution. This is based on an analysis of the nature of the dispute between those who maintain that psi does not exist (the dominant one expressed in most modern philosophy texts), and those who believe that science will eventually be able to cope with the anomalous phenomena associated with psi effects. An appeal is made for a more even-handed representation in future philosophy texts using this interpretation to help ameliorate the representation of psi phenomena.

A Layperson’s Guide to the Theory of Psychopraxia

MICHAEL A. THALBOURNE

ABSTRACT: In this brief article, the author argues that use of the terms “ESP” and “PK” often leads to ambiguities as to which of the ostensibly two processes is occurring. A particularly clear case of this is the “telepathy” situation, where ESP (of various types) or PK or both could be involved. It is argued that the paranormal process is not dual but unitary in nature; the author calls this single process “psychopraxia” (“the self accomplishing ends”), and discusses it in the context of a new theory of the paranormal.

Paranormal Effects Using Sighted and Vision-Impaired Participants in a Quasi-Ganzfeld Task

LANCE STORM and MICHAEL A. THALBOURNE

ABSTRACT: An experiment on exosomatic psychopraxia was conducted in which 42 wholly or partially blind participants were matched for age and sex with 42 sighted participants. The experimental task was to describe, paranormally, a randomly selected drawing concealed in aluminium foil and a manila envelope. Every second participant was assigned to a relaxation treatment (audio tape). Following their attempted description of the target, participants were required to rank-order 4 drawings (1 the target, and 3 the decoys). For the whole sample, based on the rankings by participants (but not those of an independent judge), the sum-of-ranks statistic was significantly positive (z = -2.98, p = .002, two-tailed), as it was also for the sighted participants (z = -2.41, p = .016, two-tailed), whereas results for the vision-impaired were not significant. The relaxation tape appeared not to induce relaxation, at least as indicated by the heart rate measure, but the ‘relaxed’ groups (the whole sample, and the sighted group, but not the vision-impaired group) scored marginally better than the respective non-relaxed groups. Belief in ESP did not affect scores in the expected direction. We refer to the significant and marginally significant effects as evidence of exosomatic psychopraxia (the latter effects indicating that relaxation might have been conducive to psychopraxia). However, a specific mode of psychopraxia¾compensation¾was not found in the vision-impaired group.
