Abstract
The purpose of the present study was to extend research on repetition and illusory truth to the domain of eyewitness suggestibility Specifically, we assessed whether repeated exposure to suggestion, relative to a single exposure, facilitates the creation of false memory for suggested events After viewing a video of a burglary, subjects were asked questions containing misleading suggestions, some of which were repeated Their memory for the source of the suggestions was tested The results show that following repeated (relative to a single) exposure to suggestion, subjects were more likely to (a) claim with high confidence that they remembered the suggested events from the video (Experiment 1) and (b) claim that they consciously recollected witnessing the suggested events (Experiment 2) The effects of repeated exposure were highly reliable and were observed over retention intervals as long as 1 week
