Answer:
This would be an example of flashbulb memory.
Explanation:
Flashbulb memory can be described as a memory so vivid that the person remembering it feels like they are seeing a snapshot of the moment. Flashbulb memories are very detailed because of the emotion associated with the event that took place. In Serena's case, she was probably very much surprised by the news of such a famous person being chased and accused of murder. That feeling has allowed her to remember that moment vividly. Still, flashbulb memories must not be taken as perfect recollections. Studies have shown they too are flawed.
