An outline and evaluation of research into the effects of leading questions on the accuracy of eyewitness testimony. It references key studies by loftus and palmer, and yuille & cutshall, focusing on the cognitive interview technique and the impact of anxiety. The document also includes mark schemes and possible content for exam questions, making it a valuable resource for students studying cognitive psychology and research methods. It explores ethical and methodological issues, offering insights into real-life applications and limitations of laboratory research. Designed to help students understand the complexities of eyewitness testimony and the factors that can influence its accuracy, such as leading questions and anxiety. It also emphasizes the importance of adapting questions to suit individual witnesses and protecting research participants from harm.

Eye Witness testimony memory questions Q1. Psychologists have carried out research into the use of cognitive interviews. One possible ethical issue which might arise during this research is protection of participants from harm.

However, an increasing number of police forces are now using the cognitive interview technique.

An American space shuttle exploded soon after it was launched. All of the astronauts on board were killed. Crowds of people were watching, including friends and relatives of the astronauts.

A researcher carried out an experiment to investigate misleading information. Participants were shown a photograph in which a man and a woman were talking. The photograph was then taken away and the participants were asked questions about it. Participants were randomly allocated to condition one or condition two. Participants in condition one were asked: Question A “How old was the youth in the photograph?” Participants in condition two were asked: Question B “How old was the man in the photograph?” (a) Why is Question A an example of misleading information? ........................................................................................................................ ........................................................................................................................ ........................................................................................................................ ........................................................................................................................

Some psychologists argue that there is always more information about an event in a person’s memory than can be recalled at any one time. This means that eye-witness recall can be improved by using certain techniques and methods. Describe and evaluate at least one way of improving eye-witness recall. Refer to evidence in your answer.

(a) One technique used in cognitive interviews is ‘report everything’. When using this technique, the police officer in this investigation read the following instructions to the participants: “Please tell me everything you can remember about what you saw in the film. Do not leave anything out, even the small details you think may be unimportant.” Identify one other technique which could have been used by the police officer in this cognitive interview. Write down the instructions that he could have read out to the participants.

Simply identifying or naming one or more potentially relevant ways of dealing with the ethical issue – maximum 1 mark. For example, confidentiality, anonymity, debrief. Further marks for explaining how psychologists could deal with this ethical issue. For example: Right to withdraw (1 mark) Participants should be reminded of their right to withdraw from the research (2 marks) If participants are showing signs of distress, the psychologist should remind the participants of their right to withdraw (3 marks).

blood (33%). Loftus and Burns (1982) found participants who saw a violent version of a crime where a boy was shot in the face had impaired recall for events leading up to the incident. However, in a real life study Yuille and Cutshall (1986) found witnesses who had been most distressed at the time of a shooting gave the most accurate account five months later. Also Christianson and Hubinette (1993) found victims of genuine bank robberies were more accurate in their recall than bystanders. AO2 = 6 Evaluation might relate to the contradictory nature of the research, possibly linked to lack of ecological validity in laboratory studies. Problems of control might also be relevant, eg in Yuille & Cutshall’s study those who experienced the highest levels of stress were closer to the event, which might have helped their recall. Ethical issues could also be relevant as could the practical applications of research. AO Knowledge and understanding

AO1 = 6 The main techniques used in the cognitive interview are summarised below. Context reinstatement – trying to mentally recreate an image of the situation, including details of the environment, such as the weather conditions and the individual’s emotional state including their feelings at the time of the incident. Recall from changed perspective – trying to mentally recreate the situation from different points of view eg describing what another witness present at the scene would have seen. Recall in reverse order – the witness is asked to recall the scene in a different chronological order eg from the end to the beginning. Report everything – the interviewer encourages the witness to report all details about the event, even though these details may seem to be unimportant. Other techniques, including those used in enhanced cognitive interviews, should be credited. In both cases, 1 mark for identifying an appropriate technique and 2 further marks for accurate elaboration. M6.

Laboratory based research has generally shown impaired recall in high anxiety conditions. In Loftus’s (1979) weapon focus experiment more participants correctly identified a person when they were holding a pen (49%) than when they were holding a knife covered in blood (33%). Loftus and Burns (1982) found participants who saw a violent version of a crime where a boy was shot in the face had impaired recall for events leading up to the incident. However, in a real life study Yuille and Cutshill (1986) found witnesses who had been most distressed at the time of a shooting gave the most accurate account five months later. Also Christianson and Hubinette (1993) found victims of genuine bank robberies were more accurate in their recall than bystanders. There is a range of acceptable answers to this question and marks should be given for effective use of the material. Answers which do not make explicit reference to this event should be awarded a maximum of 4 marks. 6 marks Effective explanation Accurate and reasonably detailed explanation of how anxiety might affect eye- witness testimony of this event that demonstrates sound knowledge and understanding of relevant research. 5 – 4 marks Less detailed but generally accurate Less detailed but generally accurate explanation of how anxiety might affect eye- witness testimony of this event that demonstrates knowledge and understanding of relevant research. 3 – 2 marks Basic Basic explanation of how anxiety might affect eye-witness testimony of this event has that demonstrates some knowledge of relevant research but detail may be muddled. 1 mark Very brief/flawed Very brief or flawed explanation of how anxiety might affect eye-witness testimony of this event has that demonstrates very little knowledge of relevant research. 0 marks No creditworthy information. M9. AO2 = 4 The answer should clearly relate to one or more of the main techniques used in a cognitive interview (other than report everything): Context reinstatement. Recall from a changed perspective. Recall in reverse order. And / or the main additional features of the enhanced cognitive interview: Encourage to relax and speak slowly.
