According to the misinformation effect, exposure to misleading post-event information typically impairs memory for the original event. Such findings are generally obtained in the laboratory using the misinformation paradigm. One component of the typical misinformation paradigm is that most of the post-event information corresponds with the event information, implying that the context surrounding the misinformation is the same as that of the original event. The present experiments investigated the role of such implication by presenting the experimental conditions with misleading items in a narrative that differed from the original event (a slide show) to varying degrees; both the location of the event and the persons described were varied. A significant misinformation effect was obtained regardless of implication condition. Even when a relationship between the witnessed event and post-event narrative was not implied, memory was impaired by the presence of misleading information. The findings are discussed in terms of retrieval blocking.
