The 20 questions
-
What was the main aim of Loftus and Palmer (1974) in Reconstruction of automobile destruction?
- To prove that eyewitnesses cannot recall any details at all
- To show that car crashes always cause serious injuries
- To test whether children remember traffic rules better than adults
- To show how the wording of a question can change a witness's memory of an event
-
In Loftus and Palmer's first experiment, participants watched films of car accidents. What was manipulated?
- The verb used in the question about how fast the cars were going
- The weather shown in the film
- The number of passengers in each car
- The colour of the cars in each film
-
What did Loftus and Palmer find about the verb 'smashed' compared with 'contacted'?
- Participants estimated higher speeds with 'contacted'
- Verb choice had no effect on speed estimates
- Participants estimated higher speeds when the question used 'smashed'
- Participants refused to estimate any speed
-
In Loftus and Palmer's second experiment, what did the 'broken glass' question test a week later?
- Whether the verb used earlier produced false memories of broken glass that was never shown
- Whether participants could recall the weather
- Whether participants could identify the car make
- Whether participants remembered the film's soundtrack
-
Which conclusion did Loftus and Palmer draw from their findings?
- Speed estimates are always accurate if the question is neutral
- Language used after an event can reconstruct and distort the witness's memory
- Witnesses should never be questioned after an event
- Memory is a perfect recording that never changes
-
Why is Loftus and Palmer's study described as a laboratory experiment?
- It was a case study of one witness over many years
- It took place in a real police station with real witnesses
- It used random allocation and controlled conditions to manipulate one variable
- It was a survey of attitudes towards crime
-
Which evaluation of Loftus and Palmer's study is strongest?
- The study proves that all eyewitnesses are unreliable in every case
- The study has perfect ecological validity because it used films
- The study has no internal validity because it used students
- The study has high internal validity but its artificial films may limit ecological validity
-
Why is the Loftus and Palmer study often used to illustrate reconstructive memory?
- It shows that films always produce accurate memories
- It shows that memory is never affected by language
- It shows that a witness's memory can be changed by information given after the event
- It shows that only adults remember car crashes
-
A witness is asked 'How fast were the cars going when they smashed?' and later reports broken glass that was never shown. What process explains this?
- Perfect storage of the event in long-term memory
- Random guessing that has no effect on memory
- Accurate recall of a real detail from the film
- Misleading post-event information altering the memory
-
Bradbury and Williams (2013) examined race effects in juror decision-making. Which broad area of research does this study belong to?
- Research on how juror characteristics and defendant race can affect judgements of guilt
- Research on the physiology of sleep
- Research on infant attachment to caregivers
- Research on childhood obesity and diet
-
Which methodological feature would be most important to evaluate in Bradbury and Williams' study of juror race effects?
- Whether participants were given a sticker afterwards
- Whether the study was published in a newspaper first
- Whether the researchers used a wooden desk in the study
- Whether the sample and mock-jury setting represent real jurors and real trials
-
What is the main strength of Valentine and Mesout's field study?
- High ecological validity because stress was experienced in a realistic setting
- Complete control of every variable in the attraction
- Freedom from any ethical concerns
- Guaranteed generalisability to all eyewitnesses
-
Which ethical issue is most relevant to a field study such as Valentine and Mesout's?
- Participants may experience distress or be unaware they are taking part, so consent and debriefing matter
- Participants never experience any stress at all
- No ethical issues arise in any field setting
- Participants are always paid too much money
-
Howells et al. (2005) evaluated brief anger management programmes with offenders. What was the main focus of this study?
- The structure of infant attachment in the Strange Situation
- The outcomes of brief programmes and the predictors of change in offenders
- The genetic basis of aggression in twins
- The effect of diet on memory in laboratory rats
-
Why is evaluating the predictors of change important in Howells et al.'s study?
- It proves that anger is always a biological problem
- It shows that every offender benefits equally from any programme
- It identifies which offenders are most likely to benefit, which can guide targeted treatment
- It removes the need for any follow-up measures
-
A brief anger management programme shows reduced reoffending at follow-up. What is the main limitation of concluding that the programme caused the reduction?
- The programme must have been delivered by a computer
- Follow-up measures are never valid in criminology
- Other factors, such as time served or support received, may explain the change
- Reoffending can never be measured accurately
-
Which contemporary study in criminological psychology is a field study on eyewitness identification under stress?
- Bowlby (1944)
- Valentine and Mesout (2009)
- Loftus and Palmer (1974)
- Rosenhan (1973)
-
What is a limitation of the mock-jury approach used in studies such as Bradbury and Williams'?
- Mock juries cannot be given any written material
- Participants know they are in a study and do not face real consequences
- Mock juries are always representative of the population
- Mock juries always contain professional judges
-
Which evaluation of Loftus and Palmer's use of student participants is most appropriate?
- Students make the study more representative of all ages
- Students are always more accurate witnesses than anyone else
- Students cannot give evidence in any setting
- Students may not represent all eyewitnesses, which limits generalisation of the findings
-
Why is it important that Loftus and Palmer used a film of an event rather than a real crime?
- It allowed the researchers to control the event so that every witness saw the same thing
- It meant participants had to act out the crime
- It made the event more dangerous for participants
- It removed the need for any measure of memory
