Abstract

This is a report of an experiment bearing on the problem of whether animals possess ESP ability. Six common household cats were the subjects. On each trial the animal went through a passageway at the end of which were two food cups. A concealed human observer tried mentally to influence the cat to eat from the cup that was the randomly selected target for the trial. The first part of the experiment was an exploratory study in which only one observer was present. During this period the cats showed a statistically significant positive deviation of choices in the direction of the experimenter\'s intention. In a second part of the experiment a second observer recorded the results without knowing which cup was the target. This section showed statistically significant trends in scoring.
