Witnesses to a crime repeat and discuss the event several times during the legal process. The repetitions and discussions may influence the quality of recall as well as the confidence a witness feels in the remembered information. To probe this matter, participants in the current study viewed a short film and then either repeatedly, over a period of three weeks, 1) discussed the event in the lab 2) discussed the event with a family member 3) repeated the event to a silent listener or 4) did nothing. Participants then free-recalled the events in the video, and answered a set of forced choice focused questions. Finally all answers were confidence-judged. For free recall, the repetition condition showed superior accuracy, confidence and calibration compared to all other groups. Discussions tended to result in higher quantity of information than all other groups, whereas accuracy, confidence and calibration remained similar to those in the control group. The groups did not differ on over/under confidence nor did they differ on slope. No group differences were found for the focused questions.
