PSI Glossary Terms I

PSI Glossary Terms

ALPHA

In the context of brain science: a distinctive brain-rhythm or brain-wave which occurs mainly in the occipital region of the cortex, and which is correlated, on the psychological level, with feelings of drowsiness, relaxation and disengaged attention on the part of the subject; it is of relatively high amplitude, and has a frequency range of between 8 and 13 Hz (Hertz, or cycles per second); of parapsychological interest as a possible physiological indicator of a psi-conducive condition in the subject. [From the Greek alpha, first letter of the Greek alphabet]

ALTERED STATE(S) OF CONSCIOUSNESS (ASC)

Expression popularized by Charles T. Tart which can refer to virtually any mental state differing from that of the normal waking condition; of parapsychological interest as possibly psi-conducive states; they include dreaming, hypnosis, trance, meditation of the yoga or Zen tradition, the hypnagogic-like state induced by the ganzfeld, and drug-induced states.

ANOMALISTIC PSYCHOLOGY

Term first used by Leonard Zusne and Warren Jones (1982) to indicate that part of psychology that investigates “anomalistic” psychological phenomena, that is, phenomena which have tended to be explained in terms of the paranormal, the supernatural, magic, or the occult; the term is also meant to include belief in UFOs, in astrology, and in such creatures as the Loch Ness Monster.

ANOMALY

Neutral term applied to a phenomenon which implies that the phenomenon is unexpected according to conventional scientific knowledge, but which does not commit the user to any particular type of explanation; sometimes sometimes preferred to “paranormal.”

AURA

A field of subtle, multicolored, luminous radiations said to surround living bodies as a halo or cocoon; the term is occasionally used to refer to the normal electromagnetic field forces surrounding the body. [Latin, from the Greek, “breath of air”]

BIOFEEDBACK

A technique which enables a person to monitor on-going changes in one of their own physiological processes; as a result of such information, the individual may be able to acquire some degree of control in regulating internal processes normally outside the range of voluntary influence; of parapsychological interest mainly in connection with altered states of consciousness and with the possibility of controlling the incidence of the alpha brain-rhythm.

ALLOBIOFEEDBACK

Term used by William G. Braud (1978) to denote the situation in which one subject, A, is attempting to influence, psychokinetically, the physiological processes of another person, B, aided by biofeedback to A concerning those processes in B. [From the Greek allos, “other,” + bios, “life,” + feedback]

CHANCE

The constellation of undefined causal factors which are considered to be irrelevant to the causal relationship under investigation; often spoken of as if it were a single, independent agency; the expression “pure chance” is sometimes used to describe a state characterized by complete unpredictability, that is, an absence of any cause-effect relationships. The term “chance” is frequently a short-hand expression for “mean chance expectation” as in “deviation from chance.”

CLAIRVOYANCE

Paranormal acquisition of information concerning an object or contemporary physical event; in contrast to telepathy, the information is assumed to derive directly from an external physical source (such as a concealed photograph), and not from the mind of another person; one particular form of extrasensory perception, it is not to be confused with the vulgar interpretation of “clairvoyance” as meaning “knowledge of the future” (for which see Precognition).

CLAIRVOYANT

As a noun, a person endowed with a special talent for clairvoyance; not to be confused with its colloquial usage meaning “a fortune-teller”; As an adjective, involving or pertaining to clairvoyance.

COINCIDENCE; IN THE PARANORMAL

Two events are said to constitute a coincidence if they occur in such a way as to strike an observer as being highly related as regards their structure or their “meaning”; to dismiss such an occurrence as a “mere coincidence” is to imply the belief that each event arose as a result of quite independent causal chains (that is, they are “acausal”) and that no further “meaning” or significance is to be found in this fortuitous concurrence; sometimes, however, a sense of impressiveness is engendered by the belief that the concurrence is so very unlikely as to have been the result of “pure chance” that there must be some cause or reason for the concurrence, thus investing the coincidence with a sense of meaningfulness. See also Synchronicity.

COLD READING

A set of statements purportedly gained by paranormal means but which in fact is wholly based on broadly accurate generalizations and/or on information obtained directly from the person seeking the reading, such as can be gleaned from facial gestures, clues in conversation, and so on.

CONTROL

(i) A personality purporting to be that of some deceased individual, believed to take control of the medium’s actions and speech during trance, and/or who habitually relays messages from the communicator to the sitter. (ii) In the context of scientific investigation, a control is something (a procedure, condition, object, set of subjects, and so on) which is introduced with the purpose of providing a check on (that is, of “controlling for”) the influence of unwanted factors.

DEJA VU

French for “already seen,” the feeling or illusion of having previously experienced an event or place actually being encountered for the first time; also called “false memory,” or “memory without recognition,” although the phenomenon could conceivably involve precognitive or clairvoyant information, in which case Frederic Myers gave it the name promnesia. [From the Greek pro, “prior to,” + mnesis, “memory”]

DERMO-OPTICAL PERCEPTION (DOP)

Term used by G. Razran to refer to the ability to discriminate color and brightness by means of touch. Also known as “skin vision,” “finger vision,” “dermal vision,” “digital sight” [From the Latin digitus, “finger, toe”], or “cutaneous perception” [From the Latin cutis, “skin”]. [From the Greek derma, “skin,” + optikos, “of sight,” derived from opsomai, “I shall see”]

DIAGNOSIS, PARANORMAL

The determination of the nature and circumstances of a diseased condition by means of extrasensory perception. See also Healing, Psychic

DISSOCIATION

A process in which a body of awareness (perceptual, memory, physical) becomes separated or blocked from the main center of consciousness; examples are trance-speaking, automatic writing, amnesia, multiple personality, and so on; thought by some to be a psi-conducive state.

DREAM, VERIDICAL

An apparently paranormal dream, inasmuch as some of the dream details give information about events normally unknowable to the experient

ELECTRONIC VOICE PHENOMENA (EVP)

Phenomena first reported by Raymond Bayless and popularized by Konstantin Raudive, consisting of sounds said to be the faint voices of deceased individuals, recorded on previously unused magnetic tapes.

EXCEPTIONAL HUMAN EXPERIENCE

Expression coined by Rhea White (see, for example, 1994, p. 5) as “an umbrella term for many types of experience generally considered to be psychic, mystical, encounter-type experiences, death-related experiences, and experiences at the upper end of the normal range, such as creative inspiration, exceptional human performance, as in sports, literary and aesthetic experiences, and the experience of falling in love.”

EXTRASENSORY PERCEPTION (ESP)

The acquisition of information about, or response to, an external event, object or influence (mental or physical; past, present or future) otherwise than through any of the known sensory channels; used by J. B. Rhine to embrace such phenomena as telepathy, clairvoyance and precognition; there is some difference of opinion as whether the term ought to be attributed to Rhine, or to Gustav Pagenstecher or Rudolph Tischner, who were using the German equivalent aussersinnliche Wahrehmung as early as the 1920s. [From the Latin extra, “outside of,” + sensory]

FANTASY-PRONENESS

A personality construct first described by Sheryl Wilson and Theodore Barber (1983, p. 340) to refer to a small percentage of the population “who fantasize a large part of the time, [and] who typically ‘see,’ ‘hear,’ ‘smell,’ ‘touch’ and fully experience what they fantasize”; such persons tend to be able to hallucinate voluntarily, to be excellent hypnotic subjects, to have vivid memories of their life experiences, and to report experiencing parapsychological phenomena.

GANZFELD

Term referring to a special type of environment (or the technique for producing it) consisting of homogenous, unpatterned sensory stimulation: audiovisual ganzfeld may be accomplished by placing translucent hemispheres (for example, halved ping-pong balls) over each eye of the subject, with diffused light (frequently red in hue) projected onto them from an external source, together with the playing of unstructured sounds (such as “white” or “pink” noise) into the ears, and generally with the person in a state of bodily comfort; the consequent deprivation of patterned sensory input is said to be conducive to introspection of inwardly-generated impressions, some of which may be extra-sensory in origin. [From the German for “entire field”]

GELLER EFFECT

The ability to bend metal by paranormal means; named after the Israeli stage performer Uri Geller, who was the first person to claim publicly the metal-bending ability; the term has been largely superseded by “PK-MB,” or, more simply, “metal-bending.”

GENERAL EXTRASENSORY PERCEPTION (GESP)

A non-committal technical term used to refer to instances of extrasensory perception in which the information paranormally acquired may have been derived either from another person’s mind (that is, as telepathy), or from a physical event or state of affairs (that is, as clairvoyance), or even from both sources; experimental parapsychologists rarely use the term “telepathy” because of the difficulty, in tests of so-called telepathy, of excluding the possible operation of clairvoyance
