| Abstract: | The current study compared the effects of co‐witness information on memory with more widely studied methods of encountering post‐event information. Participants were shown a crime video and then exposed to both correct and incorrect post‐event information about the video through one of four methods: (1) leading questions, (2) media report, (3) indirect co‐witness information, or (4) co‐witness discussion. There was also a control condition in which participants did not receive any post‐event information. All participants were individually tested on their memories for the event 1 week later. Results suggest that co‐witness information had a particularly strong influence on eyewitness memory, whether encountered through co‐witness discussion or indirectly through a third party. That is, participants were more likely to report co‐witness information than post‐event information encountered through leading questions or a media report.
