Pseudomemory effects over time in the hypnotic setting.
Highly (n = 36), moderately (n = 26), and low (n = 48) susceptible subjects were administered either hypnosis or waking instruction to examine the hypothesis that pseudomemory will occur for hypnotic subjects as long as 2 weeks after suggestions are given for accepting false events. Accuracy and confidence of memory were measured for all subjects, and memory was examined for free recall, structured recall, and recognition. Results indicated persistence of pseudomemory for the 2-week period for both highly and moderately susceptible subjects. Data highlighted the multifaceted operation of skill, contextual, and state instruction factors, and an hypothesis that ambiguity of communication when suggestion is delivered plays a part in the maintenance of pseudomemory over time is offered for further testing.
