t the activity is caused from a strong repression of hostility. In the Middle Ages, the cause was frequently thought to be the Devil, or a demon possessing a person, but currently it is thought to be a manifestation of PK activity.Another type of PK activity is thought by those who experience it to be associated with death, danger or other emotional crisis. In such incidents persons reports falling pictures, clocks which stop, or stopped clocks which start, and shattering of glasses. The persons feels these incidents have indicated a death, or some highly emotional crisis.PK research is currently being done in the areas of meditation and other altered states of consciousness. Experiments also are being conducted to determine the existence of retroactive PK, or "retro-PK" where subjects try to influence an event such as a sequence of numbers as produced by a random event generator. The subjects try after the event has happened. However, it is impossible to rule out the possibility of the PK effect being unconsciously exerted by the subject or the experimenter on the generator during the number selection.Although PK is not generally acknowledged by scientists, many parapsychologists believe that well-controlled experiments have established its existence. Thus far laboratory tests have not established this exclusively. Results on the whole have been insignificant. But, the greater potential, many believe, that PK testing will open up wider capacities for mental ability. A.G.H.Sources: 29, Gertrude Schmeidler, The City College, New York, 61. ...
