memory - misleading information (EWT) Flashcards
what is a leading question?
a question that suggests a certain answer because of the way it’s phrased
who researched leading questions?
Loftus and Palmer (1974)
watched film clips of a car accident
About how fast were the cars going when they hit each other?
contacted - 31.8mph
smashed - 40.5mph
response-bias explanation
the wording of the question has no effect on the memory, but influences how they decide to answer
substitute explanation
the wording of the question changes the participant’s memory
research support for substitute explanation
Loftus and Palmer repeated their experiment and participants with the verb ‘smashed’ were more likely to report seeing glass even though there wasn’t any
what is post-event discussion?
occurs when there is more than one witness - they discuss what they’ve seen which can influence the accuracy of their recall
who studied post-event discussion?
Gabbert et al (2003)
participants in pairs - watched same crime from different POVs, then discussed
71% of participants recalled aspects of the event they didn’t see
memory contamination
discussion causes their memory to be altered or distorted because they combine information from other witnesses with their own memories
memory conformity
witnesses go along with each other to win social approval or because they believe the others are right
actual memory is unchanged
strength - real-world application
leading questions and police
psychologists explain limits of EWT to juries at court trials
counterpoint - ethical implications
limitation - lab setting
Loftus and Palmer (1974) had participants watch film clips in a lab, which is significantly less stressful from witnessing a real event
Foster et al (1994) pointed out that there are far more important consequences for eyewitnesses’ memory in real life
limitation - evidence against substitution
Sutherland and Hayne (2001) studied leading questions and found participants’ recall was more accurate for central details and so resistant to misleading information
