ABSTRACT
L. Eilbert and Gertrude R. Schmeidler investigated the relationship between Extrasensory Perception (ESP) scoring and such factors as work habits, frustration, and attitude toward the experiment. The ESP symbols were displayed on a blackboard and the abbreviations written against each symbol. In addition to the attitude questionnaire and target lists for the clairvoyance tests, the experimental materials included standard record sheets with provision for recording ten runs of the subject's responses. The ESP record sheets of the subjects, along with the duplicates, were checked, and the correct responses were totalled independently by two different individuals. They were further checked in the Parapsychology Laboratory at Duke University. The method of scoring the questionnaire was worked out with the aid of the staff of the Parapsychology Laboratory, Duke University. The total ESP score of 590 runs of the subjects in the pilot group was 2,900 hits, a negative deviation of 50 below-chance expectation, which is not significant.
