RESUMO

The detection and processing of novelty play a critical role in memory formation. The effect of novelty intervention in memory has been demonstrated with rodents in several lines of research; however, it has not been explored as extensively in humans. In this research, we evaluated the effect of novelty exposure on two types of emotional memory: visual (Study 1) and verbal (Study 2). Eighty healthy volunteers participated in both studies. First, all participants watched a video (session 1); seven days later (session 2), participants in the control group watched the same video and those in the experimental condition were exposed to a novel one. Immediately after exposure, all participants looked at 36 pictures (or listened to 36 words). Soon afterward, a two-task test was administered to evaluate memory (immediate free recall and recognition). A week later (session 3), the two-task test was run again (deferred free recall and recognition). Regarding emotional memory processing, the emotional information was more activating and better remembered than the neutral one, for both visual and verbal information. Regarding the novelty effect, the participants exposed to the novel video had better recall than the control on the deferred measures. Thus, our results provide evidence of the effect of novelty exposure on two different types of emotional memory, with great potentialities in clinical and educational settings.
