When Misinformation Improves Memory

In two experiments, we explored the effects of noticing and remembering change in the misinformation paradigm. People watched slide shows, read narratives containing misinformation about the events depicted in the slide shows, and took a recognition test on which they reported whether any details had changed between the slides and the narratives. As expected, we found a strong misinformation effect overall. In some cases, however, misinformation led to improved recognition, which is opposite the usual finding. Critically, misinformation led to improved recognition of the original event when subjects detected and remembered a change between the original event and the postevent information. Our research agrees with other findings from retroactive-interference paradigms and can be interpreted within the recursive-remindings framework, according to which detecting and remembering change can enhance retention. We conclude that the misinformation effect occurs mostly for witnessed details that are not particularly memorable. In the case of more memorable details, providing misinformation can actually facilitate later recollection of the original events.
