(LC) Memories of a Memory
Have you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell 16? Have you ever experienced a time when you couldn't really describe
something you saw in a way that others could understand? It so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific Inquiries and trials. New insights into human memory suggest
human memories are really a mixture of many non-factual things
First, memory is vague. Imagine your room at home or a classroom you see every day. Most Holy, you could describe the room very generally. You could name the color of the wails, the floors, the decorations. But the image you
describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may
recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."
Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day
at a Ibray you go to quite frequently, you witness an argument between a Ibrary patron and one of the librarians. Later, when telinga friend about the event, your brain may remember a familar librarian behind the desk rather than the
actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story
Third, your memory changes over time. It also changes the more you retall the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also
shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are rebelling a story, notice what you add, or what your brain wants to add to the account. You may also
notice that you drop certain details from previous tellings of the story
with individual memories at jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your tather throwing rocks into the
river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras If we want to record the true picture
