Thirdly, it allows the participants an opportunity to remove their results from the study. The dependent variable is believed to be under the control of the independent variable. The way they think Like before, This showed a difference of 9mph based on verb used. You'll balance pursuing important research objectives with using ethical research methods and procedures. The overall aim for the study that Loftus and Palmer carried out was to investigate whether changing the phrasing of Loftus and Palmer (1974) conducted a classic experiment to investigate the effect of leading questions on the accuracy of eyewitness testimony. + ApplicationDespite the low ecological validity in this study, we may find some ecological validity from the task which the participants were required to complete. Reasons why diffusion of responsibility was not found: Loftus and Palmer set out to study how subsequent information can affect an eyewtinessess account of an event. In the previous example about the blue bird, there was an interpretation of the information of the blue flying thing and it was recorded in memory as blue bird. Therefore, for Loftus and Palmers study, we can say both individual and situational factors had an impact (adsbygoogle = window.adsbygoogle || []).push({}); For example, Milgram (1963), Zimbardo (1973). also be looked at. This is because it helps them to understand how to get Loftus and Palmer's study could also be considered socially sensitive as the participants were shown videos of car crashes, that for some could have cause distress. Loftus and Palmer (1974) Psychology Study. consistent and very controlled. One factor that might affect memory is previous Instead of dealing with theories of misinformation, she began to look at the possibility of being able to plant a specific false memory for an entire event that never took place. broken glass. One week later the dependent variable was measured - without seeing the film again they answered ten questions, one of which was a critical one randomly placed in the list: Did you see any broken glass? A further problem with the study was the use of students as participants. for this reason we can say that participants have the freewill to make the decisions that they make. Just like the first experiment there was a critical, how fast were the cars going when they SMASHED into, question, About how fast were the cars going when they, 150 participants were called back and were asked 10. watching the video, they were all asked to describe in their However, the verb used in the question, had a slight The task and the experiment was the same for everyone and werent They argue that we have no are many factors, which make eyewitness testimony unreliable. realism). It relies on heavily on the memory of the eyewitness (person who saw an event) and until Elizabeth Loftus and colleagues started considering the reliability of memory, the court system assumed that the memory of eyewitnesses was highly accurate.

ETHICS. Johnson and Scott invited participants to a laboratory where they were told to wait in the reception area. Slide 18. who took part in the experiment were showed 7 car The conclusion were that 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. Her main focus has been on the influence of (mis)leading information in terms of both visual imagery and wording of questions in relation to eyewitness testimony. reconstructs an individuals memory. 7 films of traffic accidents, ranging in duration from 5 to 30 seconds, were presented in a random order to each group. This was a laboratory experiment with five conditions, only one of which was experienced by each participant (an independent measures experimental design). They support the values required for collaborative work, such as mutual respect and fairness. (adsbygoogle = window.adsbygoogle || []).push({}); Participants' speed estimates were faster than reality. (2) All the tasks and the procedure was procedure). the respondents answers - and that only the verb-condition was There were five different verbs used, all of which had different levels of intensity. They were then given a questionnaire which asked them to describe the accident and answer a set of questions about the incident. experiment 1 was due to distortion of memory. The study has also had real-world implications; based on + Laboratory study the laboratory environment allows the researchers to control many aspects of the environment and experience of the participant, which reduces confounding variables and thus increases the internal validity of the study. She began to examine this potential theory because of a legal case she'd been asked to provide . To test this hypothesis, Loftus and Palmer asked people to estimate the speed of motor vehicles using different forms of questions after they had observed a car accident. Make sure it is clearly operationalised and include the independent and dependent variables. Therefore we can say the IV did For example, the were deceived into believing that there was broken glass at the scene of the accident. This debate if perfect. What type indicated that happened interviewed immediately following the testimony and legal settings Loftus and Palmer's first experiment showed how leading questions. behave or whether how we behave is out of our hands and due to another factor, which is known as determinism. 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. It is the account of an event which a person has witnessed. make. Another reason why the experiment has low population validity is due to the fact that Arousal is reduced by helping (directly/indirectly), leaving the scene of the emergency or rejecting the victim as undeserving of help.

Just like experiment one, people who heard the verb, They may remember the sequence of events, or they may have even been in the shop or house when the robbery happened. Ensuring that your results are anonymous and also confidential follows the ethical code put forth by the British Psychological Society.

This means that the American culture may have a different way of replying to leading questions than those who Therefore, they are less likely to know the speed at which the cars were travelling at so their estimates would Calculate the mean, median and mode speed estimates for both the 'smashed' and 'hit' conditions. Secondly, Loftus and Palmer (1974) suggest that the results could in fact be due to a response bias, that is to say, the participant adjusted their estimate of the speed based upon the verb used and did not experience an actual distortion in their memory. . Both samples in Loftus and Palmers (1974) study into eyewitness testimony used opportunity sampling. Background informationLoftus & Palmer wanted to . Some people may have had explain why memory isnt perfect and what it actually is that affects, and reconstructs, our memory. 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?. Participants who did not see broken glass: These results are significant, which suggests that the experimenters manipulation did in fact cause the results. Controlled experiment: Loftus & Palmer conducted their research using experiments. (age of participants, incident viewed, environment, etc). interviewing witnesses, both by police immediately or soon after an event and also by lawyers in court An example of an eyewitness testimony can be when an eyewitness can give evidence to the police about a robbery that may have happened. them a clue on what to say. recalled seeing broken glass at the car crash. Why was the Lost in the mall study unethical? This is very similar to how the police and court system addresses eyewitness testimony and thus this study has great applicablity for the criminal justice system, as it advises against the use of leading questions. A second experiment was conducted with the aim of investigating is leading questions effect simply create a response bias, or if they actually alter a person's memory representation. or how good their memory is, can affect how good or bad a persons memory is. Research ethics matter for scientific integrity, human rights and dignity, and collaboration between science and society. The individual side outline two ethical issues from loftus and palmer research. guidelines in for police questionning of witnesses and suspects. Yuille, J. C., & Cutshall, J. L. (1986). University of Washington formed an opportunity sample. And for these Loftus and Palmer offer two possible explanations for this result: If the second explanation is true we would expect participants to remember other details that are not true. The study took place in a lab using The addition of false details to a memory of an event is referred to as confabulation. If there were significantly more participants who recalled seeing broken glass in one condition compared with another, then we may determine that the results are due to the manipulation in the experiment or confounding variables.
