Abstract

Recent experiments have demonstrated a significant change in the variance of ESP runs with changing test conditions. This paper attempts to develop a theory of the mechanism underlying such an effect, postulating that a psi-hit process triggers a psi-miss protective mechanism as a result of strain on the organism produced by the psi hits. This is conceived in a learning theory paradigm in which Hull\'s inhibitory effects suggest a parallel to the psi process. An experiment to test the theory is outlined.
