Flashbulb memories: Do they differ in intensity or accuracy?

When you can remember a lot of detail from a certain moment or incident which occurred in the past, then one tends to assume that the memory is accurate. There are many possible trains of thought which might lead to this assumption. It is possible that one thinks "I remember this happening so clearly, therefore it must have happened exactly as I see it in my mind." It has been assumed that flashbulb memories stay the same over time; that these memories cannot be falsified.

However, researchers have proved that these assumptions are false by studying the details which people recall regarding an incident very soon after it occurred, and then after a considerable amount of time has passed. Our textbook provides several examples of such studies. Here is an article about a study conducted on students from Duke University after the terrorist attacks during 9/11; this study was conducted to determine the accuracy of these memories.
Another much debated issue surrounding flashbulb memories is the claim that flashbulb memories are not a different kind of memories. We cannot argue that a memory is accurate by virtue of the fact that it is a flashbulb memory. It seems more likely that flashbulb memories are different from others only in the vividness and intensity of the memory- accuracy is not affected in the least by whether a memory is a flashbulb memory or not. Here is an article that further expounds this hypothesis.
