Q

explain deception in Johnson and Scotts study

A

-believed they were in waiting room when experiment was already taking place

Q

evaluate the ethics in loftus and palmers study

A

-deception as unaware different verbs
-so no informed consent

17
Q

evaluate the methodology in loftus and palmers study

A

-lab experiment with an artificial task
-lacks mundane realism and ecological validity

18
Q

evaluate the application in loftus and palmers study

A

-suggests courts and police interviews should avoid leading questions to increase accuracy

19
Q

evaluate the sample in loftus and palmers study

A

-limited sample
-lacks population validity as results cannot be generalised

20
Q

define post event discussion

A

-occurs when there is more than one witness to an event
-witnesses may discuss what they have seen with co witnesses or with other people
-this may influence the accuracy of each witnesses recall

21
Q

procedure of Fiona gabberts study

A

-studied participants in pairs
-each participant watched a video of the same crime but filmed from different point of view so they saw different elements
-both participants discussed what they had seen
-individually completed recall test

22
Q

findings of Fiona gabberts study

A

-71% of participants mistakenly recalled aspects they picked up in discussion
-0% in control group with no discussion mistakenly recalled aspects

23
Q

conclusion of Fiona gabberts study

A

witnesses go along with each other either to
-win social approval
-or they believe the other witnesses are right and they are wrong (memory conformity)

24
Q

explain the source monitoring theory

A

-memories of the event are genuinely distorted
-the eye witness can recall information about the event but can’t recall where it came from (source confusion)

25
Q

explain the conformity theory

A

-recall changes to go along with the accounts of co witnesses
-to win social approval
-or because they genuinely believe other witnesses are right and they are wrong

26
Q

evaluate the ethics in Fiona gabberts study

A

-deception as unaware they watched different videos
-no informed consent

27
Q

evaluate the methodology in Fiona gabberts study

A

-lab experiment with an artificial task
-lacks mundane realism and ecological validity

28
Q

evaluate the application in Fiona gabberts study

A

-police would use the conclusion of this experiment
-the court would want to be aware of post event discussion

29
Q

evaluate the sample in Fiona gabberts study

A

-120 people
-60 students from Aberdeen university
-60 older participants from local community
-so cultural bias

30
Q

what are the 4 factors of cognitive interview

A

-recall/report everything
-context reinstatement
-reverse order
-change perspective

31
Q

describe the recall/ report everything technique

A

-a person should recall every minor detail from the event no matter how insignificant it may seem
-they shouldn’t select what information to report

32
Q

describe the context reinstatement technique

A

-interviewer encourages the witness to mentally recreate an image of the situation including details of the environment
-eg the weather, time (using their senses)

33
Q

describe the reverse order technique

A

-the witness is asked to recall the event in a different chronological order
-eg end to beginning

34
Q

describe the change perspective technique

A

-the witness is asked to mentally recreate the situation from different points of view
-eg the point of view of someone else who was present

35
Q

describe geiselmans study on cognitive interview

A

-89 students asked to watch a video of a crime
-two days later half interviewed with standard, half with cognitive interview

36
Q

results on cognitive interview study

A

mean number of items correctly recalled
-standard interview =35.58
-cognitive interview=41.67
mean number of items incorrectly recalled
-standard interview=8.61
-cognitive interview=8.57

37
Q

evaluate the research support for cognitive interview

A

-cognitive interview compared to standard interview showed more items were correctly recalled
-so it is more effective
-but number of incorrect recall was similar

38
Q

evaluate cognitive interview being time consuming and expensive

A

-takes significantly longer as focuses on 4 points
-police officers have to spend more of their hours doing it
-costs a lot to train police officers in it
-so takes away from other police roles

39
Q

evaluate cognitive interview having implications on the economy

A

-helps retrieve more accurate memories than standard interview
-so miscarriages of justice such as Ronald cotton are prevented
-stronger prosecution cases save police and legal system’s time and resources
