The use of psi in such a way that the target at which the subject is aiming is “hit” (that is, correctly responded to, in a test of extrasensory perception; or influenced, in a test of psychokinesis), more frequently than would be expected if only chance were operating; the term is also sometimes used, misleadingly, to refer merely to nonsignificant positive scoring. Hence, “psi-hitter,” a subject who exhibits a tendency to psi-hit. Compare Psi-Missing. [Abbreviated to Ψ H by James Carpenter]
