The present experiment examined the effect of a subliminally presented symbiotic gratification and a magic of believing message on academic achievement. Graduate students were randomly assigned to one of the two experiemental message conditions, or to a control message condition, and received on the average 12 sessions, 10 exposurers per session, of 4-msec visual subliminal presentation of one of the three messages. Each session occurred immediately prior to a lecture in either a statistics or a measurement class. Each of the courses was taught in a traditional manner by the regular faculty, who were naive regarding the experimental conditions. Objective final examinations for each course revealed statistically significant differences in favor of the symbiotic gratification experimental condition over the control condition. No differences were obtained between the symbiotic and magic of believing conditions. Research and clinical implications of the findings are also explored.
