Abstract

Examined whether an exceptional male psi subject could remotely influence the performance of a female influencee on the "ESPerciser" computer game. The ESPerciser combines principles of forced-choice and free-response ESP and allows for testing in both clairvoyance and precognition modes. The experiment consisted of 8 sessions, each of which contained 10-trial runs. The S\'s task was to make the influencee score higher on targets with a white background than on those with a colored background, or vice versa. The influencee was misinformed that the S would try to make the score high on some runs and low on others. For half the sessions, the S actively tried to exert influence while observing the game over a video monitor; for the other half the S merely hoped for the correct outcome while engaging in other activities. The influence effect occurred only in the latter condition. Several alternatives for the psi source of this effect are discussed. The fact that the effect w!as suggestively stronger on precognition runs reinforces the designation of this particular S as the principal source. The results are interpreted as providing support for the experimenter psi hypothesis.
