Hypnosis and pseudomemories: the effects of prehypnotic expectancies.
Contrary to predictions, the pseudomemory rate of subjects who received prehypnotic information that hypnosis increased recall was indistinguishable from the pseudomemory rates of subjects who received information that hypnosis did not increase recall and of subjects who received no specific prehypnotic information. Indeed, by the last recall trial, none of the 47 subjects exhibited pseudomemory. Subjects exhibited faulty memory of events that actually occurred (i.e., pencils spilling), and were as uncertain of events that actually occurred, as they were of suggested events that did not occur during the session (telephone ringing). Subjects were generally consistent in their certainty, or lack of it, across events. Finally, subjects led to believe that hypnosis is an altered state of consciousness were less aware of external events, and had the lowest rate of recall of target suggestions compared with subjects in the comparison groups.
