Wright, Mathews and Skagerberg
wanted to test how people influence others memories. They held three experiments. The first experiment tested the memory of
people who were presented with high-frequency words, low-frequency words and
non words with twenty words in each group.
They then recalled their memory by themselves and then put into pairs
with a confederate and were asked to respond to the stimulus. For the second experimental study, they were
shown one-hundred pictures of cars and rated them on a scale from 1 (being
average) and a 7(being most unique). The
same procedure in the first experiment was used for the second one. The model used to interpret the data was
based on the Multilevel Logistic Regression Model and the signal detection
theory. They also used ANOVA to interpret
their data. The participants were more
likely to rely and conform to the responses of the confederates for unseen
items as compared to seen ones. The
third experiment was shown pictures of white male faces to set the stimulus as homogeneous. This group were not paired with confederates
and responded to the stimuli individually.
They were asked which faces they had already seen and which ones they do
not remember. They used the same
techniques to interpret the data. On
average, the three experiments concluded that the participant’s responses were
influenced by the confederate for both new and old items. This demonstrates that that a person can be
easily affected by a false memory of a nonexistent event than to report a
memory of an actual one.
This
article is interesting because it shows how easily people’s memories can be
manipulated and influenced to become false.
It also demonstrates how easy it is for people who are unsure of seeing
something to conform to another’s view and accept it as their own. This is particularly important in eyewitness
reports and their validity and reliability.
The article gives the example of the Oklahoma City Bombing and the
witness of Timothy McVeigh purchasing a vehicle. The owner did not remember him but a mechanic
remembered him and falsely remembered an accomplice with him, soon everyone in
the shop reported to have a memory of both of the men. In reality he was by himself. This can also hold true for eyewitness
testimony for crimes. Why is eyewitness
testimony relied on so heavily, when we are aware that people’s memories are easily
manipulated? I think this study should
allow us to reevaluate the importance of eyewitness testimony in court cases
and convictions.
