Final answer:
A flashbulb memory is an exceptionally vivid and detailed memory of an important event that feels permanently etched into one's memory. They can be related to personal milestones or significant global events and involve a narrative recollection of the 'what, where, and when' of an event.
Step-by-step explanation:
A flashbulb memory is one of historical or personal importance that feels etched permanently into memory. This term refers to an exceptionally clear and vivid recollection of an important event, which people often remember with great detail. A prominent example provided by research is how most Americans who were at least eight years old during the 9/11 terrorist attacks can still recall where they were and what they were doing when they heard the news, even years after the event occurred.
Flashbulb memories are not limited to global events; they can also pertain to personal milestones or significant experiences shared within a smaller group, like a family or a school. It's important to note that while much of the research and conversation about flashbulb memories involve negative events, positive events can also create these vivid, long-lasting memories.
The characteristics of a flashbulb memory include strong emotional associations, a sense of permanence, and an often detailed narrative-like recollection of the 'what, where, and when' of an event, falling under the category of episodic memory.
