Flashbulb Memory Experiment

A flashbulb memory is an unusually vivid, snapshot-like memory of the circumstances in which you first learned about a shocking public event. Brown and Kulik coined the term in 1977 after studying people's memories of the assassination of John F. Kennedy — most Americans could describe exactly where they were, who they were with, and what they were doing at that moment.

Not necessarily. Follow-up studies, including Neisser and Harsch's 1992 research on the Space Shuttle Challenger disaster, found that people were highly confident in their flashbulb memories — but about a third of participants misremembered key details a few years later, sometimes completely. Vividness is a feeling of certainty, not a guarantee of accuracy.

Two factors stand out. First, the event is surprising and emotionally intense, which boosts attention and rehearsal — you replay the moment and talk about it with others. Second, the 'now print' quality proposed by Brown and Kulik suggests the brain may encode the surrounding context almost photographically at a moment of personal or collective significance. The result feels like a snapshot, even when details fade.

Researchers use the 'flashbulb event' method: shortly after a major public event (an assassination, a disaster, a national tragedy), they ask participants for the canonical details — where they were, what they were doing, who told them, how they felt — and then test the same people again months or years later. The gap between confidence and consistency is one of the most replicated findings in memory research.
