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 under Psi; Retroactive PK; Recurrent Spontaneous Psychokinesis. [From the Greek psyche, “mind, soul,” + kinesis, “a moving, disturbance,” derived from kinein, “to set in motion”]
