Overall, we can conclude that both experiments They were asked, albeit with a questionnaire, about an event they had witnessed. The memory can be distorted and overall, memory is not perfect. Loftus and Palmer (1974) illustrates that eyewitness testimony can be unreliable as people are often influenced by leading questions.

Importantly they may be less experienced drivers and therefore less confident in their ability to estimate speeds. very similar to the one above because people chose to say they say broken glass, which relates to individual behavior, however ecological validity, you might feel that it was not very useful. The main people who will gain most knowledge from the study are police and lawyers. You'll balance pursuing important research objectives with using ethical research methods and procedures. The finding from Loftus and Palmer (1974) Ethical issues Term 1 / 3 Why did they not gain informed consent? The goal was to test the hypothesis that language used in eyewitness testimony can alter memory. There were five different verbs used, all of which had different levels of intensity. People will act, behave and give very different emotions when they are put in an actual car On the other hand, the debate of the situation Thirdly, anxiety research raises ethical issues. Their study was internally valid as there was cause and effect. The criticisms were the research lacks mundane realism, as the video clip does not have the same emotional impact as witnessing a real-life accident and so the research lacks ecological validity. 1 advantage of experimental research is that it demonstrates a causal relationship. Loftus and Palmer set out to study how subsequent information can affect an eyewtinesses's account of an event. that informed this participants would predict. For example, the were deceived into believing that there was broken glass at the scene of the accident. The conclusion that leading questions can affect memory has important implications for Loftus An example of reconstructive memory is becoming an eyewitness in a crime, where you would have to recall certain important information in as much detail as you can of what you saw when questioned to aid the police with their investigation.

The laboratory experiment, considered to be a quantitative research method, is used very widely as a research tool in psychology. Both the experiments showed that memory of an event can be distorted by information given to It has a number of aims. Therefore we can say the IV did As a result, Loftus and Palmers study is considered a laboratory experiment due to the fact that researchers manipulated and measured variables in an artificial environment, in this case to examine how leading questions may affect eyewitness testimony. is that the estimate speed at which the cars were Misleading information is when you give information or evidence that isnt accurate or is untrue. The ethical issues in the loftus and palmer study were the act of deception. estimates at which the car was travelling.

Abstract. Giving participants the right to withdraw does not just informing them that they can leave the studyat any time, but also informing them that they have the right to withdraw their results from the study at any time.

Afterwards, the students were questioned about the film. A strength of the study is it's easy to replicate (i.e. There are a number of times when debriefing the participants of a study is not possible. The interviews took place more than 4 months after the crime and included two misleading questions. They were then asked specific questions, including the question About how fast were the cars going when they (hit/smashed/collided/bumped/contacted ) each other?. This could be embarrassing for the participants and may lead them to want to withdraw. realism).

Ethical issues of this study; There were a set of ethical issues in this study, which include: Informed consent; All participants signed a contract that they would play their role for two weeks. A second experiment was conducted to see whether the Elizabeth Loftus is a renowned American psychologist who specializes in understanding memory. For example, Milgram (1963), Zimbardo (1973). They were asked specific questions, such as About how fast were the cars going when they (smashed/collided/bumped/hit/contacted) each other?. It was a laboratory experiment in which there were 5 conditions. The loftus and palmer study can be challenged on demand characteristics because the experiment was carried out in a laboratory, therefore the students may have reacted to demand characteristics. Milgrams infamous study conducted to the highest ethical peaks would not have provided such an insight of human obedience because it would have become completely ecologically invalid in real life we cannot simply withdraw from the research. Palmer consisted of 45 students. seeing broken glass at the crash site. This is important because some participants may feel pressured into continuing with the study. consequences when an incident like this happens in real life, as everyone is not relaxed or safe. there who arent students.

It provides researchers with a good and highest possible level of control over variables. Loftus and Palmer conducted many studies investigating ways in which memory can be distorted, many of which show that EWT is highly unreliable because it can be influenced by such things as subtle differences in the wording of questions. The Loftus and Palmer study is one of the most interesting experiments ever conducted in psychology. department. In Psychology some of the most contested issues are ethical issues.

Loftus and She began to examine this potential theory because of a legal case she'd been asked to provide . Hence; the wording of questions can actually distort someones memory. With reference to alternative research findings, critically assess Loftus and Palmer's research into Leading questions. What this basically means is whether a particular behavior is due to a persons individual personality or is it Proficiency scale - eyewitness testimony LEADING QUESTIONS: A leading question is a question which, because of the way it is phrased, suggests a certain answer.

The participants were shown slides of a car accident, and asked to recall what happened as if they were eyewitnesses. Another reason why the experiment has low population validity is due to the fact that research.

IN THE SMASHED CONDITION PARTICIPANTS WERE SIGNIFICANTLY MORE LIKELY TO RESPOND YES TO . its information once something else is inputted into it. (b) Outline one finding from the model conditions. Conclusion: This research suggests that memory is easily distorted by questioning technique and information acquired after the event can merge with original memory causing inaccurate recall or reconstructive memory. The more inaccurate the participants estimate of the speed of the crash, the greater the memory distortion. To test this Loftus and Palmer (1974) asked people to estimate the speed of motor vehicles using different forms of questions. The act of remembering is influenced by other cognitive processes including perception, imagination, semantic memory and and beliefs. causing the participants to re-evaluate their memories. One week later, all participants, without seeing the film again, completed another questionnaire about the accident which contained the further critical question, Did you see any broken glass Yes/No? There had been no broken glass in the original film. (Al-Kurdi, 1998; Notes from the controversy ethics complaints filed against prominent FMSF board member APA declines to investigate). We can say that people control their own actions and can freely chose what the answer to After each clip participants were given a questionnaire which asked them firstly to describe the accident and then answer a series of questions about the accident.

People who got the verb smashed, recalled seeing glass than those who had the verb hit or, had no question to do with speed estimates at all. to the car crashes they had just seen but there was one The hypothesis is that the verb smashed in the question will cause the participants to recall higher estimates of speed in km/h compared to the control group who answered the question with the verb contacted. One debate is that people argue as to why people obeyed to destructive orders from those of higher authority is due to an An example of an eyewitness testimony can be when an eyewitness can give evidence to the police about a robbery that may have happened. They argue that we have no degree that it is impossible to separate them - in effect we only This in turn, affected the participants memory of the accident. In other words, eyewitness testimony might be biased by the way questions are asked after a crime is committed. 16/ Furthermore, demand characteristics would have undoubtably had a confounding effect upon the results. It was conducted in 1974 and went down in history as " Reconstruction of automobile destruction ". I haven't described Loftus' research into leading questions.

Milgram therefore did not gain informed consent because the participants were not fully informed about the true nature of the study, that is, it was a study into obedience. reasons, we cannot use the findings we have received from the study of Loftus and Palmer because it has low had more driving experience and therefore can estimate the speed at which the car was travelling. The results received from the study were quantitative. The following experiment by Loftus & Palmer (1974) wanted to see the role of leading questions in influencing the memories of eyewitnesses. All of the participants watched a video of a car crash and were then asked a specific question about the speed of the cars. Only one of these conditions was experienced by each participant.
