Flashbulb memory has always been classified as a type of autobiographical memory, which is memory for one's everyday life events. Emotionally neutral autobiographical events, such as a party or a barbecue, were contrasted with emotionally arousing events that were classified as flashbulb memories. Memory for the neutral autobiographical events was not as accurate as the emotionally arousing events of Princess Diana's death and Mother Teresa's death. Therefore, flashbulb memories were more accurately recalled than everyday autobiographical events. In some cases, consistency of flashbulb memories and everyday memories do not differ, as they both decline over time. Ratings of vividness, recollection and belief in the accuracy of memory, however, have been documented to decline only in everyday memories and not flashbulb memories.
