Abstract

Tested the capacity of the Defense Mechanisms Test (DMT) to predict performance of a free-response ESP task in the ganzfeld. The percipient -order effect hypothesis found by the 1st author (1972) in a previous study predicts that the scores of the 1st percipient will be lower than that of the 2nd percipient in each pair of Ss to participate in a session. After a pilot study with 8 Ss, 30 Ss with high and low scores on the DMT participated in 38 ganzfeld sessions. 10 direct hits and 28 misses were obtained. Results do not support the hypothesis; in fact, the relation of ESP and DMT scores was in a direction opposite to that found in forced -choice ESP experiments. (13 ref)
