The influence of delusional ideation and dissociative experiences on the resistance to false memories in normal healthy subjects

The influence of individual differences in a measure of delusional ideation (Peters et al. Delusional Inventory; Peters et al., 1999) or dissociative experiences (Dissociative Experiences Scale; Bernstein & Putnam, 1986) on the production of false memories was examined. Using a modified DRM procedure, outcomes that were consistent with the activation/monitoring account of DRM false memories (e.g., Roediger et al., 2001) were observed. In addition, it was found that scores on both scales were associated with increased rates of false recall of the non-presented lure and with a poorer performance on a measure that assessed unsuccessful source monitoring. However, neither score was associated with veridical memory. These results contribute to better understand the influence of individual differences on the resistance to false memories.
