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. [ABSTRACT FROM AUTHOR]

Since Brown and Kulik's (1977. Flashbulb memories. Cognition, 5, 73–99. http://doi.org/10.1016/0010-0277(77)90018-X) seminal work, a central issue in memory literature is whether flashbulb memories (FBMs) hold a special status within autobiographical recalls. To address this issue, we refer back to Brown and Kulik's definition of FBM as a snapshot of the reception context of an important public news and propose a method to identify the contents of this snapshot. Although Brown and Kulik found that the majority of FBM's contents could be classified within six canonical categories (CCs), here we claim that assessing the presence of FBMs through guided CCs' questions – as done by most researchers in this field – can be misleading. We suggest, instead, to use free recall reports to identify the consistent perceptual elements of the snapshot. Across two test-retest studies, we show that the contents of FBMs assessed by free reports and the contents of CCs assessed by guided questions, do not exactly coincide. Moreover, a structural equation model supports results of previous research about the determinants of FBM and reveals that FBM facilitates the recall of more consistent explicitly requested CCs' contents. Theoretical implications concerning the qualitative contents of FBMs and the debate about their consistency are discussed. [ABSTRACT FROM AUTHOR]
