This study examined (prospectively) the impact of the emotional content of visual scenes on memory accuracy and susceptibility to misinformation over time. After viewing a highly positive and highly negative photographic image, half of participants (N ϭ 80) were exposed to misinformation concerning the images and later responded to a series of questions about the details of each. After 1 week or 1 month, participants returned and were asked (unexpectedly) about the images. Overall, memories of misled participants were substantially less accurate than nonmisled participants, a pattern persisting at 1-week and 1-month follow-up, although the passage of time decreased accuracy of all participants. Relative to positive images, negative images were associated with a greater susceptibility to false memories for a major misleading detail at both sessions. Thus, relative to positive emotion, negative emotion specifically heightens suggestibility in the presence of major misinformation.
