Abstract/Summary

Emotional public events, relative to nonemotional ones, are typically remembered more accurately, more vividly, and with more confidence. However, the majority of previous studies investigating this have focused on negative public events and less is known about positive ones. The current study examined whether positive and negative public events were remembered in a similar manner by assessing individuals’ memory for the time when they learned the results of the United Kingdom’s 2016 Referendum on its European Union (EU) membership. Participants included U.K. participants who voted to leave the EU in the referendum and found the event highly positive, U.K. participants who voted to remain in the EU and found the event highly negative, and U.S. participants who did not vote and found the event neutral. Data from a total of 851 participants were assessed at four time points over the course of 16 months. Growth curve modeling showed that differences in memory between participants in the Remain group (who reported the highest levels of negative emotion) and those in the Leave group (who reported the highest levels of positive emotion) emerged over time. Specifically, Remain participants maintained higher levels of memory consistency than Leave participants, whereas Leave participants maintained higher levels of memory confidence than Remain participants. These results indicate that positive and negative public events are remembered differently, such that negative valence enhances memory accuracy, while positive valence results in overconfidence.
