Factors effecting accuracy of eyewitness testimony
Post-event discussion is a potential source of misleading information where witnesses discuss what they saw after an event.
we exclude other information about the situation.
In a state of anxiety, we tend to focus on whatever is making us feel anxious
Loftus and Palmer
leading questions affect the accuracy of EWT
“How fast were the cars going when they (hit/smashed/collided/bumped/contacted ) each other?”
lab experiment with five conditions
Independent measures design
Asked specific questions,
Pps shown slides of a car accident involving a number of cars and asked to acxt as eye witnesses to the crash
45 US students
easy to replicate
used laboratory experiment which followed a standardised procedure.
results cant be generalised
Students are not representative of the general population .
used students as participants.
lacks ecological validity
video doesn't have the same emotional impact as witnessing a real-life accident
lacks mundane realism
Pps who were asked the “smashed” question thought the cars were going faster than those who were asked the “hit” question.
The estimated speed was affected by the verb used.
