Flashbulb memory
A flashbulb memory is a vivid, detailed memory of where you were and what you were doing when you heard surprising, emotional news. Roger Brown and James Kulik named it in 1977. It feels like a photo, but studies show these memories change over time about as much as ordinary ones. What stays high is your confidence in them.

In more detail
Flashbulb memories are about the moment you heard the news, not the event itself: the room, who told you, what you were holding. Brown and Kulik thought surprise and personal importance switch on a special mechanism that prints the scene. Emotion does make the memory feel sharper, and people retell these stories often, which keeps them alive.
The accuracy has not held up. Ulric Neisser and Nicole Harsch asked students the day after the 1986 Challenger explosion how they heard the news, then asked again about two and a half years later. Many accounts had changed, some completely, and people were still sure of them. After 9/11, Jennifer Talarico and David Rubin (2003) tested 54 Duke students the day after and again 7, 42 or 224 days later. Consistency dropped as fast as for an ordinary memory from the same days. Only vividness and belief in accuracy stayed high.
The study lesson: confidence is not accuracy. The feeling that you know a chapter works the same way. A page you just reread feels familiar and clear, but that tells you little about whether you can produce the answer cold on exam day. Test yourself and let the result, not the feeling, decide what you review.
Flashbulb vs everyday memories after 9/11 (Talarico and Rubin, 2003)
| What was measured | Flashbulb memory | Everyday memory |
|---|---|---|
| Consistency of details over time | Dropped | Dropped at a similar rate |
| Vividness | Stayed high | Dropped |
| Belief that the memory is accurate | Stayed high | Dropped |
Example
Maya remembers the action potential lecture vividly: the professor's animation, the joke about sodium, where she sat. She is sure she understands it and skips it when she reviews. A 10-question quiz the next day shows she can explain depolarization but mixes up what happens during repolarization. The vivid memory of the lecture told her nothing about what she could actually answer.
How to use it
- 1
After reading, close the material and write down what you remember before you judge how well you know it.
- 2
Rate your confidence for each answer, then check it. Mark every spot where high confidence met a wrong answer.
- 3
Treat those confident mistakes as top priority. They are the ones you would never review on your own.
- 4
Retest a few days later, because an answer that was right once can still drift.
- 5
For AP Psychology, tie the term to its two key facts: vivid and confident, but not reliably accurate.

Common questions
Are flashbulb memories accurate?
Not as accurate as they feel. In studies after the Challenger explosion and after 9/11, people's accounts changed over months and years about as much as ordinary memories did. What set flashbulb memories apart was that vividness and confidence stayed high. Emotion strengthens the feeling of remembering more than the accuracy of the details.
What is the difference between flashbulb memory and episodic memory?
A flashbulb memory is a kind of episodic memory. Episodic memory covers any personal event tied to a time and place. Flashbulb memories are the special case linked to surprising, emotional news, and they feel unusually vivid. They also belong to autobiographical memory, the story of your own life.
