Mediumship - Research

Research

In Britain, the Society for Psychical Research has investigated some phenomena, mainly in connection with telepathy and apparitions. According to an article in the Journal of the Society for Psychical Research, in some cases media have produced personal information which has been well above guessing rates. One of the more noteworthy recent investigations into mediumship is known as the Scole Experiment, a series of mediumistic séances that took place between 1993–98 in the presence of the researchers David Fontana, Arthur Ellison and Montague Keen. This has produced photographs, audio recordings and physical objects which appeared in the dark séance room (known as apports). According to paranormal researcher Brian Dunning the Scole experiments fail in many ways. The seances were held in the basement of two of the mediums, only total darkness was allowed with no night vision apparatus as it might "frighten the spirits away". The box containing the film was not examined and could easily have been accessible to fraud. And finally, even though many years have passed, there has been no follow-up, no further research by any credible agency or published accounts.

The VERITAS Research Program of the Laboratory for Advances in Consciousness and Health in the Department of Psychology at the University of Arizona, run by Gary Schwartz, was created primarily to test the hypothesis that the consciousness (or identity) of a person survives physical death. Schwartz claimed his 2005 experiments were indicative of survival, but do not yet provide conclusive proof.

An experiment conducted by the British Psychological Society suggests that under the controlled condition of the experiment, people who claimed to be professional mediums do not demonstrate the mediumistic ability. In the experiment, mediums were assigned to work the participants chosen to be “sitters.” The mediums contacted the deceased who were related to the sitters. The research gather the numbers of the statements made and have the sitters rate the accuracy of the statements. The readings that were considered to be somewhat accurate by the sitters were very generalized, and the ones that were considered inaccurate were the ones that were very specific.

In a 1973 essay published in the University of the Witwatersrand medical school journal, “The Leech”, current director of the Pacific Neuropsychiatric Institute, Vernon Neppe proposed that the human personality survives bodily death and concluded that that the “dead” have communicated with the living. Neppe referenced A.C. Munday-Castle’s hypothesis on the neurophysiological implications of parapsychology; a timeless, spaceless universe in which all things or events exist but in a more dormant sense, where drugs such as LSD may free the cerebral cortex from the “modulating effect of the brain stem reticular activating system,” allowing the cortex to run free. Neppe described a possibility that under such circumstances the individual is exposed to a purely mental universe, independent of matter, that contains all mental events, which may in some way overlap or be interlinked with the ordinary physical four-dimensional universe. Neppe also proposed that scientific investigation of parapsychological phenomena regarding brain function may imply an attempt to test the validity of these experiences. Neppe describes one such scientific investigation:

In a study of twelve subjects, ten women and two men, ranging in age between 18 and 66 years, and consisting of eleven mediums and an “automatic writer” (all of whom volunteered through the agency of the South African Society for Psychical Research), G.K. Nelson adopted the following procedure: routine EEG examinations were carried out, usually with the subject in a separate room from the recording equipment. Photic stimulation was the only activating procedure applied in all cases. Six cases went into a trance after an initial few minutes of EEG monitoring.

In the resting EEG recordings, ten out of the twelve eases showed localized signs of temporal lobe instability. The young automatic writer showed a partial suppression of alpha rhythms on the left side. Asymmetries and or asynchronies of EEG activity were therefore present in 11 of the 12 subjects almost equally divided between the dominant and non-dominant hemispheres as far as the site of maximum effect was concerned. (Interhemispheric differences in amplitude of the alpha rhythm are by no means uncommon; indeed the alpha amplitude often tends to be lower in the dominant hemisphere. It is only when the amplitude in one hemisphere is less than half that in the other that one takes particular note of such a difference — the EEG of the automatic writer showed such a difference.

EEG abnormalities of the kind often found in the interictal EEGs of patients with epilepsy were seen in five cases in the form of paroxysmal bursts or focal spikes and sharp waves. Three other cases showed occasional sharp waves, raising the possibility of cortical hyperexcitability. Only four cases had EEGs of the kind usually associated with epilepsy and there were no reports of fits in the histories of any of the twelve volunteers. For these reasons the possibility exists that if the EEG signs are valid indices of temporal lobe dysfunction this is of a non-epileptic kind.

According to Neppe, although the validity of mediumistic experience is neither confirmed nor denied by the presence of an unusual anatomical or physiological characteristic in the brain, such findings show that parapsychological phenomena are at least partly a function of the brain, and could serve to strengthen the hypothesis that certain people by reason of their individual pattern of brain function may be in a position more readily to experience a mental universe which is independent of matter.
