Three experiments investigated memory distortions produced by scripts activated when hearing a story. In Experiment 1, participants heard a story with one of two alternative titles. At test, the words that were falsely recognised varied according to the title of the story, though the story itself was the same for all participants. Experiment 2 replicated this effect and found that words rated as central to a script were more likely to be falsely recognised than words rated as peripheral. Participants in Experiment 3 heard a cryptic story with a disambiguating title presented either before, after, or not at all. Script-based errors were observed only in participants given the title before the story. In all three experiments, falsely recognised words were frequently categorised as "remember" responses, based on illusory conscious recollection. These findings show that inferences produce a powerful illusion of memory that is not simply due to verbal associations.
