Have you ever been an eyewitness at the scene of a crime? If you were, do you
think that you would be able to accurately describe, in precise detail,
everything that happened and remember distinct features of the suspect? Many
people believe that yes they would be able to remember anything from the events
that would happen and the different features of the suspect. Some people, in
fact, are so sure of themselves after witnessing an event such as this that
they are able to testify that what they think they saw was indeed what they
saw. However, using an eyewitness as a source of evidence can be risky and is
rarely 100% accurate. This can be proven by the theory of the possibility of
false memory formation and the question of whether or not a memory can lie.
There have been several experiments done to try to prove that false memories
can indeed be formed. One experiment, for example, was tried with a 14-year-old
boy. The boy was told four memories, one of which was falsely constructed but
similar to that of a true memory. The memories that were suggested took place
when the boy was about 10 years younger. As the false memory was retold to him,
he was asked to explain in detail what he had remembered from that event.
Surprisingly, he claimed to remember the event, even though it was falsely
created by the interviewer and his brother, and went on to explain what he
remember to have happened, details and all. After collecting everything he had
said about the four memories, he was told that one of the suggested memories
was made-up and he was asked to guess which one it may have been. When he
couldn’t decide which one it was, he was told that it was in fact the memory of
getting lost in a store. He was confused and had trouble believing the truth.
Similar studies were done to a different set of college students and they
tended to have the same results. After giving as much detail about each memory,
the students were interviewed about what they may have written done about what
they had remembered. During the last part of the experiment, each of the
students were debriefed and asked to guess which memory they believed was
false. Of the 24 students interviewed, a total of 19 students correctly chose
the false memory, sometimes because of process of elimination, as being the
false one (Loftus & Pickrell p 9 (5p)). This means that there are five
students, 21%, which “testified” that they remembered something that actually
never happened. How would you like to be the accused criminal with one of these
five students? Not quite as reliable as you may have hoped a memory would be.
