“…Numerous studies have substantiated PoetzPs (1960) original claim that unreported elements of marginal stimuli often emerge in the content of subsequent fantasy products of the perceiver. While PoetzPs "fantasy" medium constituted dream reports, the effect has been variously obtained with other types of dreamlike or fantasylike materials, including daydreams (Shevrin & Luborsky, 1958), free associations (Allers & Teler, 1960;Haber & Erdelyi, 1967;Hilgard, 1962), and doodles and imagery (Eagle, Wolitzky, & Klein, 1966;Fisher, 1956;Fisher & Paul, 1959;Fiss, Goldberg, & Klein, 1963;Giddan, 1967). The generated fantasy material is used, in effect, as a detection indicator-the phenomenon being denned by a difference in measured availability between intential recall and fantasy.…”
