This study demonstrates the
susceptibility of people witnessing an event to
remember a false detail by misinformation in post event interviews and
the
effect of emotions in accurately remembering memories. The
experiment
showed a sample of ninety students divided into three different groups
which
viewed either a negative, neutral or positive picture of an emotional
scene
(i.e. an accident). They were told to analyze the picture and
then an
hour later was subjected to ten questions. Five of the ten questions
for half
of the people in each of the three groups were dedicated to misleading
information with false details. Compared to the group witnessing
events
involving the neutral and positive based emotions, the negative
emotionality
groups outcome of the study consisted of more then half of the people
subjected
to the misleading questions, recalled the false detail an hour after
looking at
the picture. They also remembered fewer central details, more
peripheral
details and their memory was less accurate in recalling certain
information
from the picture.
I find this interesting because this study demonstrates conditions which involve eyewitness testimony, something that is crucial and constant in courts and police reports on a daily basis. Misleading questions can mislead your memory into believing something that did not happen. Due to the inaccuracy of eyewitness testimonies, this study demonstrates that witnesses of crime due to their emotions are vulnerable to suggestibility by questioning and may in fact mislead investigators of facts and can even lead to misidentifying criminals.
