Flashbulb Memory

A flashbulb memory is one that is vividly imprinted on the brain due to an extremely unexpected or emotional event. The September 11 attacks and the JFK assassination are examples of events that can cause people to remember exactly where they were and what they were doing when the events occurred. The heightened emotional significance of these events causes our memories to become hyper-aware, which is why you can remember small details many years after the event has happened. The repetition that comes from the media is another reason that these memories can be so vivid and lasting.
