How will I know if I am learning?
By the end of the lesson…
Will be able to define the own age bias.
C Will be able to explain how age affects EWT.
Will be able to evaluate research into the
effects of age on EWT.
Read the article on a child eye witness.
What does this suggest about children as eye
How reliable are they?
There is some potentially traumatic material in the article. If
you feel uncomfortable, leave the article and think about
the potential flaws of using children as eye witnesses.
Look in your envelope. There are lots of
cards with different pieces of research
into age and EWT. Sort them into research
that suggests older eye witnesses are
more accurate, and research that
suggests younger witnesses are accurate.
Summarise the findings in your table.
Older EW’s are most
Younger EW’s are most
How conclusive is the evidence? Why might this be?
Can you think of any
points of any of these findings?
Hint: What about ethical issues
The majority of studies have tested college age
students who were asked to identify same age
Studies which have tested older adults have also
used college students as targets.
Anastasi & Rhodes (2006) used individuals from
three age groups. They had to rate 24
individuals (from different age groups) for
attractiveness. Later they were presented with
48 photos: 24 they had seen previously, and 24
% of correct recognition in each age group.
What do these results imply about age of the participant
and age of the target?
Apparent age effects may be due to the fact that
people do best when asked to identify people of
their own age group.
Perhaps this is because we have more contact with
people who are a similar age to us. The lesser
experience we have, the greater the own age
When we encounter people of our own age group
more regularly we become better at processing
those faces and therefore have better memory

You’re a psychologist advising the police on how to deal
with their witnesses. An old woman and young man have
just been witnesses to a middle aged man holding a store
up with a gun. The old woman was behind the gun-man in
the queue but the young man was outside the shop and
could only see through the top half of a window.
With reference to this situation, advise the police on what
problems they might encounter and fill in the simple
advice grid below so they can work with it easily and
come back to it when they need to revise their knowledge.
Look at the table in your booklet.
Try to summarise all the information you have learned over
the past few lessons on factors which influence EWT.
To what extent does age influence the
accuracy of eyewitness accounts?
And finally – Using Psychological
research, answer the following question.
How does age influence the accuracy
of EWT (4 marks).
