Age and Eyewitness Testimony
AGE AFFECTS EYEWITNESS TESTIMONY
AGE DOES NOT AFFECT EYEWITNESS TESTIMONY
Parker and Carranza
lab experiment
compared primary school children and college students
correctly identify a target individual following a slide of a mock crime
Children less accurate than adults
EVALUATION
easily replicated
test-retest reliability
no ethical concerns because the study was a false one so no one was really harmed and therefore no lasting damage to people
not generalisable
not representative
not ecologically valid
Yarmey
stopped adults in public place and sked them to recall physical characteristics of a women they had just spoke to minutes ago for 15 seconds
no difference in accurate recall between age groups
EVALUATION
representative
generalisable
ecologically valid
difficult to replicate as there are many extraneous variables
Memon et al
studied two groups:16-33 and 60-82 years
when delay was short between incident and recall NO DIFFERENCE
when delay was a week (longer) older participants significantly less accurate
EVALUATION
generalisable
representative
replicable
not ecologically valid
no ethical concerns
Anastasia
Age own bias
people more accurate when remembering features of those similar to there selves
e.g. age, race, ethnicity, background etc
