A review of longitudinal studies on flashbulb memories. Where we started, are, and are going?

Abstract

Since Brown and Kulik (1977) coined the term ‘Flashbulb memories’ (FBMs), there are still heated debates about their nature. We thus considered it useful to take stock of almost 50 years of research by reviewing 57 test–retest studies on FBMs for public events. The review aimed to answer six research questions by examining the target events and populations investigated (RQ1); the methods used to assess differences among groups and the effect of time on memory (RQ2); the assessment of FBMs' contents (RQ3), consistency (RQ4), vividness and confidence (RQ5); the criteria used to draw studies' conclusions (RQ6). Results show a huge methodological heterogeneity which may have contributed to the different conclusions about the special status of FBMs. The in‐depth comparison of 9/11 studies suggests that results may differ depending on the methods used. Finally, the paper provides methodological suggestions for future FBMs studies and seeks to stimulate critical theoretical reflections.
