The misinformation effect has long been studied, but little research has examined how misleading post-event information affects traumatic memory. Misinformation presented by a cowitness has been found to be particularly powerful, often producing the strongest effects on eyewitness memory. The current study sought to analyze the impact of co-witness misinformation on memory for a traumatic event. Participants viewed a short film displaying a gruesome murder and completed an immediate recall test. After a short delay, participants read a narrative summary of the film (accurate or misleading), with some being told the narrative was written by another eyewitness. A subsequent recall test was given. Significant misinformation effects were found despite the traumatic nature of the film. The co-witness information did not impact recall of misleading items as expected. Implications for eyewitness memory for traumatic events are discussed.
