Pseudomemory effects over time in the hypnotic setting
Article Abstract:
The phenomenon of pseudomemory, the recollection of an event that did not actually occur, has been the subject of much interest of late. In particular, the ability of hypnosis to distort memory has been examined. The mechanisms by which this may occur are not clear; genuine memory distortion, report bias, and perhaps a variety of other influences have been suggested to account for this phenomenon. Several studies have indicated that individuals who are highly or moderately suggestible to hypnosis are more inclined to report pseudomemory after a false memory is suggested while under hypnosis. The length of time that pseudomemory persists was examined in this study, which included 110 subjects. The individuals were grouped by their degree of susceptibility to hypnosis, including 36 highly, 26 moderately, and 48 minimally susceptible individuals. It was hypothesized that the effects of pseudomemory would persist for relatively long periods. The subjects were given suggestions while under hypnosis or while they were awake. A general memory performance test was administered after the suggested event (subjects had been shown a video). The subjects' memory of the suggested event was tested for recognition, structured recall, and free recall two weeks after the exposure. Those who were considered highly or moderately susceptible to hypnosis showed a persistence of pseudomemory over this time period. A variety of influences that may be involved in this observed effect are discussed. These results substantiate the fact that individuals who are highly or moderately susceptible to hypnosis are most inclined to develop pseudomemory, and that this pseudomemory may persist two weeks or longer.

Influence of rapport on hypnotically induced pseudomemory
Article Abstract:
A study to examine the importance of rapport in hypnotically induced pseudomemory was conducted. There were three studies made to explore the role rapport had in the study. Subjects for the entire study numbered 209 women and 99 men. Results indicate that rapport has great influence on cued recall. Rapport increases when subjects are positively reinforced and decreases when negatively reinforced. A number of alternative explanations are provided.
