This article presents a summary of the findings of our ongoing research program on the fantasy-prone person. In seven studies, nearly 6,000 college students were screened in order to obtain five samples of 156 fantasyprone subjects. Fantasy-prone subjects (fantasizers) were selected from the upper 2%-4% of the college population on a measure of imaginative involvement and contrasted with non fantasizers (lower 2%-4%), and medium fantasyprone subjects (middle range). General support was secured for Wilson and Barber's construct of fantasy proneness: Fantasizers were found to differ from non fantasizers, and in many cases also from medium-range subjects, on measures of hypnotizability, imagination, waking suggestibility, hallucinatory ability, creativity, psychopathology, and childhood experiences. Differences in hypnotizability were most reliable when subjects participated in a multisession study and were screened not only with the screening inventory, but also with an interview that substantiated their fantasy-prone status. However, our findings indicated that less correspondence between fantasy proneness and hypnotizability exists than Wilson and Barber suggested. Hypnotic responsiveness is possible even in the absence of well-developed imaginative abilities, and not all fantasizers were highly hypnotizable. Fantasizers recollected being physically abused and punished to a greater degree than other subjects did and reported experiencing greater loneliness and isolation as children. Many fantasizers appeared to be relatively well-adjusted; however, a subset of fantasizers were clearly maladjusted based on self-report, Minnesota Multiphasic Personality Inventory (MMPI), and Rorschach test data. Because of the diversity inherent in the fantasy-prone population, it is misleading to think of individuals at the extreme end of the fantasyproneness continuum as conforming to a unitary personality type. was believed to facilitate a temporary absorption in sat-January 1 9 8 8 9 American Psychologist
