Eye Witness Testimony Flashcards
Eye Witness Testimony definition
Ability of people to remember the details of events, which they have observed
like i missed u changing ur pads…how dare u not invite me
Misleading information definition
Incorrect information given to the eye witness usually after the event
oh dey been fooled. damn. i would have severe trust issues after this. maybe thats where i went wrong. am i…the problem?
Leading questions
A question that suggests a certain answer
Post-event discussion
Occurs when there is more than one witness to an event
Witnesses may discuss what what they have seen with other co-witnesses
This effects accuracy
they b like. ha we got away w it and shi. then the ‘other witness’ pulls off his crocheted mask and says boohah i am de police officer U FOOL. den we all get arrested and b happy and die
Describe the Loftus and Palmer lil 1974 study
Aim = if asking leading questions affect the accuracy of recall
Method = participants shown car accident clip. Some asked how fast car travelling when it HIT other car. There were 5 groups asked (hit, smashed, contacted, bumped and collided)
Results = those who heard ‘smashed’ gave a higher estimated speed than those who heard hit (hit = 34.0pmh, smashed = 40.8mph)
Conclusion = it is ok to smash ur best friend and it wont b gay
well maybe
Leading questions will affect the accuracy of recall. The word smashed led participants to believe the car was going fast
What is the response bias explanation
Suggests wording of question has no real effect on participants’ memories but influences how they decide to answer
doesnt make sense. franky…i cried in my own arms about it. but thats ok. its lattice. move the fuck on
Describe the 2nd Loftus and Palmer experiment bout broken glass
WHO COULD SLICE THEIR THROATS QUICKER
i would win
Method: 150 participants were shown a short film that shower a multi-vehicle car accident and then they were asked questions about it. Participants were split into 3 groups (with 50 in each group)
1st = speed when hit
2nd = speed when smashed (very fast im very good at the smashing of my lovers)
3rd = asked nothing about speed
All groups returned a week later and were asked
“Did u see any broken glass?” even tho there was none in the film
das lying. lying is a sin
What were the results on 2nd experiment of Loftus and Palmer broken glass
Smash = 34 yes, 16 no
Hit = 7 yes, 43 no
Control = 6 yes, 44 no
What is the subsitution explanation
Supported by Loftus and Palmer 1974
Wording of leading question actually changes participant’s memory of from clip
Critical verb altered memory of incident
What is post-event discussion
When co-witnesses to a crime discuss it with each other
This means their eye witness testimonies may become contaminated
golly gosh this is a disgrace
icl u and me would do that and fuck up an entire police investigation
They may combine misinformation from other witnesses with their own memories
Describe Gabbert’s post event discussion experiment 2003
yo das when sistah was born whoop
Procedure = student participants in pairs
Each watched a video of the same crime but filmed from different point sof view
Meant each participant could see elements in event that other could not, e.g. only one participant could see the title of the book being carried by a young women
Both discussed what they had seen b4 individually completing a test of recall
Findings = 71% of participants mistakenly recalled aspects of event that did not see but had picked up in discussion
and that is why u should trust NO ONE
