Psychokinesis – Parapsychological Definition:
Psychokinesis is a paranormal action; term coined by Henry Holt and adopted by J. B. Rhine to refer to the direct influence of mind on a physical system that cannot be entirely accounted for by the mediation of any known physical energy. See also Psi-Kappa; Retroactive PK; Recurrent Spontaneous Psychokinesis.
[From the Greek psyche, “mind, soul,” + kinesis, “a moving, disturbance,” derived from kinein, “to set in motion”]
Term used to refer to psychokinetic effects brought about on living systems; examples of such effects would be the paranormal speeding up or slowing down of the sprouting of seeds or of the growth of bacteria, the resuscitation of anæsthetized mice, and so on; may also include psychosomatic effects; symbolized “PK-LT” (“psychokinesis on living targets”) by J. B. Rhine; modern researchers refer to it as DMILS, or direct mental influence on living systems.
A disturbance characterized by bizarre physical effects of paranormal origin, suggesting mischievous or destructive intent: these phenomena include the unexplained movement or breakage of objects, loud raps, the lighting of fires, and occasionally personal injury to people; in contrast to a haunting, the phenomena often seem to depend upon the presence of a particular living individual, called the “focus,” frequently an adolescent or child; and apparitions are rarely seen.
[German: literally, “noisy ghost”]
Psychokinestic Metal Bending (PK-MB)
A psychokinetic effect in which metallic objects such as keys, cutlery and so on are subjected to more or less permanent deformation or other structural change.
Recurrent Spontaneous Psychokinesis (RSPK)
Expression coined by William G. Roll to refer to paranormal physical effects which occur repeatedly over a period of time, especially used as a neutral description of poltergeist disturbances.
Psychokinesis occurring in such a way as to be an instance of retroactive causation; to say that event A was caused by retroactive PK is to say that A would not have happened in the way that it did had it not been for a later PK effort exerted so as to influence it. Sometimes abbreviated to “retro-PK;” also referred to as “backward PK” or “time-displaced PK”.
