Anastasi and Rhodes
· Showed 3 groups of participants (young, middle aged and
old) 24 photographs and asked them to rate them for
· Later on showed them 48 photos (24 originals along with
24 distractor photos) and asked them to pick out the
original 24 photos.
· Found that young and middle aged participants had a
much more accurate recall of the photos than older
participants. Also all 3 groups remembered faces of their
own age better than the other ages.
· This shows that younger people have a more accurate
recall than older people and that everyone remembers
faces of their own age group better than other age
groups…read more

Anastasi and Rhodes- evaluation
· High internal validity- participants shown same 24
photos the only change was the age of the person in
the photo (the IV) meaning that we can be sure that
the results are down to the IV and not another
confounding variable
· Good ethics- no harm caused as no violent crime was
· Low ecological validity- used photos won't produce
the same amounts of stress that witnessing a real
crime would so the results are invalid and cannot be
applied to actual crimes…read more

· Gave adults and children a story to read
· Afterwards asked them 20 questions about the
story, 15 of which were misleading
· Found that children were more influenced by
misleading questions than adults as they answered
more of the misleading questions incorrectly.
· This shows that children are less accurate in EWT
as they are more influenced by misleading questions.…read more

witnessing a real crime, anxiety may be higher in a
real crime
· Ethics- no harm caused by stress or distress as a
story was used and no violent crime…read more

· Studied old and young participants
· When the delay between an incident and its
identification was short (35mins) there was no
difference between the age groups and the accuracy
of their recall. However, when the identification was
delayed 1 week older participants had significantly
less accurate recall than younger participants.
· This shows that younger people are more accurate
with recall and therefore more reliable in EWT…read more
