We have all forgotten something at some point and time in our lives, some more than others. When tragic events happen, or something emotionally arousing, we seem to remember our feelings from that point and time in our lives. But there is some controversy on how much can we trust our memories. A multitude of studies have shown that our memory is not like a video camera, capturing everything play by play, but that it can change over time. Tragic events such as the Challenger (space shuttle) explosion, assassination of JFK and September 11th have impacted people's lives, but a few years after these events have occurred, peoples stories have changed on what they were doing and how they were feeling. Flashbulb memories deteriorate over time just like everyday memories. The only difference is that flashbulb memories come with great vividness and confidence although they can be very inaccurate. It has been documented that people who were involved in a flashbulb event have more accurate recollections compared to people that who were not involved in the event. Also, younger adults can form flashbulb memories more readily than older adults. Studies have also shown that flashbulb memories can also be created from non-surprising events. So how much can we actually rely on our memory?
