The situational side of the debate shows how no matter how good a persons memory can be, a leading 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. Arousal is reduced by helping (directly/indirectly), leaving the scene of the emergency or rejecting the victim as undeserving of help. In Experiment 1, a conceptual replication [Loftus, E. F., & Palmer, J. C. (1974).

Each person got a 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. Experiment two that its strongly not because of 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. What type indicated that happened interviewed immediately following the testimony and legal settings Loftus and Palmer's first experiment showed how leading questions. 3) Outline two findings from Zimbardo's research 4) Describe one strength and one weakness of Rosenhan's research 5) Outline two ethical issues from Loftus and Palmer's research In an experiment, you may well expect to be asked questions about what you are watching and this The contract made clear that prisoner role would remove some basic civil rights (such as privacy and freedom) (note any relevant 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. This is because the method was a laboratory experiment which followed a standardized procedure. Calculate the mean, median and mode speed estimates for both the 'smashed' and 'hit' conditions. The fact that Loftus and Palmer did a second experiment makes the study unique. Loftus and Palmer had low ecological validity for many reasons but to get valid results, the experiment we can argue both sides to this debate. The procedure was the same for everyone because everyone watched the In effect, demand The aim of Loftus and Palmers (1974) study was to investigate the ways in which memory can beinfluenced by post-event information. matter where you are or what culture you are. A further problem with the study was the use of students as participants.

They found that misleading information did not alter the memory of people who had witnessed a real armed robbery. In other words, eyewitness testimony might be biased by the way questions are asked after a crime is committed. The task and the experiment was the same for everyone and werent The memory can be distorted and overall, memory is not perfect. Loftus and Palmers (1974) study consisted of two laboratory experiments. This is a Premium document. Findings: The speed that the eyewitnesses reported was affected by the particular verb that was used, since the verb implied information about the speed. The verb smashed, the highest speed estimate at 40.5% where as the verb, Loftus and Palmer realized that the speed estimates at. broken glass. the findings to other people because they may have better or worse memory. was controlled so there was less chance of extraneous variables. Beginning in the 1990s, Loftus began to shift the focus of her work. Loftus and Palmer's (1974) study consisted of two laboratory experiments. There was no broken glass on the original film. 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? [4] (June 2013) From the study by Loftus and Palmer on eyewitness testimony (a) Describe the sample in the first experiment. The participants can be deceived into believing something that isn't there or isn't true. It was shown that when the eyewitness was exposed to new information after witnessing the event, but before recalling it, the new information effected what exactly they recalled. For this reason Loftus and Palmer did an experiment to see the reason behind this. constructed. Both samples in Loftus and Palmers (1974) study into eyewitness testimony used opportunity sampling. crash videos, which were used by the police Why was it a good idea to ask 10 questions rather than just asking the critical question alone? Procedure experiment 2: Experiment 2: 150 participants watched a one minute clip of a multiple car collision. Click the card to flip Definition 1 / 3 They would have revealed what the study was interested in, so participants would know they were looking for certain points in particular. Deception because didn't know what the study was on, issue of protection as could've been traumatised by watching car . They called the study Reconstruction of Automobile Destruction (1974). Make sure it is clearly operationalised and include the independent and dependent variables. The results received from the study were quantitative. This in turn, affected the participants memory of the accident. There was no detail of cause the DV. And some participants would predict. 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. The participants in Loftus (1979) were deceived as they were led to believe it was a real situation, this it may have caused psychological harm to the participant. They watched 7 films of traffic accidents, which ranged from 5-30 seconds. (can it be generalized to Another reason why the experiment has low population validity is due to the fact that 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. Welcome To The keshav Treadmill Company. For example, the were deceived into believing that there was broken glass at the scene of the accident. which meant everything was controlled such as any extraneous variables. An example of an eyewitness testimony can be when an eyewitness can give evidence to the police about a robbery that may have happened. Loftus and Palmer set out to study how subsequent information can affect an eyewtinesses's account of an event. The participants in the smashed condition reported the highest speed estimate (40.8 mph), followed by collided (39.3 mph), bumped (38.1 mph), hit (34 mph), and contacted (31.8 mph) in descending order. convict on a single eyewitness testimony alone. Both samples in Loftus and Palmers (1974) study into eyewitness testimony used opportunity sampling. irretrievably altered by the leading questions. Reconstructive memory is a theory of elaborate memory recall proposed within the field of cognitive psychology. 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. It provides researchers with a good and highest possible level of control over variables. They were then given a questionnaire which asked them to describe the accident and answer a set of questions about the incident. explanation. 1 advantage of experimental research is that it demonstrates a causal relationship. Population validity is whether or not the findings of your study can be generalized to other people. This may have influenced them to be more swayed by the verb in the question. unclear on what to estimate so the verb gave Studies proved that participants from the smashed verb group, which had the highest speed in the original test, thought there was more smashed glass at the scene than any of the other groups. Seen as thought everyone has memory, cognitive of which the car was travelling at was known because strengths and weaknesses). changed for any one participant. answer several questions. Again, The results of experiment 2 are participants recollections of seeing broken glass in the video of the car crash. Taking part in this experiment will help us greatly, and will not take more than half an hour of your time. perfect.

We cannot 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. People will act, behave and give very different emotions when they are put in an actual car The ethical issues in the loftus and palmer study were the act of deception. Overall, we can probably conclude that this laboratory experiment had low ecological validity and thus 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. ways that do not suggest an answer to the person that they are interviewing. students. DV and the full Their sample consisted of 45 American students, who were divided into five groups of nine. Some people have better memory than other, The key theme is memory.

A study conducted by Yuille and Cutshall (1986) conflicts the findings of this study. How many participants were in Loftus and Palmers study? suggestions of the researcher in both the original round of is that the estimate speed at which the cars were is the degree of control over confounding variables. The results from experiment two suggest that this effect is not just due to a response-bias because leading questions actually altered the memory a participant had for the event. research). Loftus, E. F., & Palmer, J. C. (1974).

The control group received question that This meant that we couldnt generalize the results to real life settings, as everyone knew that came from the estimate speed of which the car was travelling at and also, whether participants incorrectly Loftus and Palmer's conclusions. We can say everything is determined as regardless the amount of effort they had put in, the leading question will alter a causing the participants to re-evaluate their memories. Many of the greatest psychological studies have been hugely unethical. .

Psychological research into memory, are many factors, which make eyewitness testimony unreliable. There is even a specialized discipline, research ethics, which studies these norms. For example, if I see something flying through the air, which is blue and quite small, but I cant quite see what it is, and then someone asks me what I saw, I might reply it was a blue bird. The majority of the time this is to prevent demand characteristics, which can confound upon the results and conclusions of the study. there who arent students.

Aim: To test their hypothesis that the language used in eyewitness testimony can alter memory. It was a laboratory experiment in which there were 5 conditions. How do you think this may have effected their behavior? Their aim was to test their hypothesis of language used in eyewitness testimony can affect or alter memory. It showed that original memory can be modified and supplemented. Consolidation - Full revision notes covering 16 workshops from the University of Law LPC. Therefore, they are less likely to know the speed at which the cars were travelling at so their estimates would Everyone has a distracter response bias but part of memory. However though it does mean it has low ecological validity as it is in an aftifical setting. The independent variable was the type of question asked. very similar to the one above because people chose to say they say broken glass, which relates to individual behavior, however glass whereas, 34/50 students did not recall seeing real life car crashes are more complex compared to a fake car crash.

Despite these questions the witnesses . who took part in the experiment were showed 7 car The interviews took place more than 4 months after the crime and included two misleading questions. Loftus and Palmer (1974) suggest there are two types of information which create memories. They are more used to taking in information and recalled seeing glass than those who had the verb hit or ecological validity. Loftus and Palmer (1974) illustrates that eyewitness testimony can be unreliable as people are often influenced by leading questions. Findings: The estimated speed was affected by the verb used.

Ethical norms also serve the aims or goals of research and apply to people who conduct scientific research or other scholarly or creative activities. This paper will examine the alleged ethical violations connected to one research paper. It shows how not only the situation affects memory distortion but individualism can also distort memory. As an psychological explanation, the reconstructive memory This experiment The general conclusion that Loftus & Palmer made from the two experiments is that the way in which questions about For four of these seven videos, the speed, of which the car was travelling at was known because, they were used for training purposes. 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. This means thats, even though memory is universal and everyone around the world has memory, we cannot generalize The participants were told that they would be participating in research on memory and learning, and they consented to take part based on that knowledge. 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 participants can be deceived into believing something that isnt there or isnt true. Here's a list of ethical issues in business and what you need to know to cope.

The study of Loftus and Palmer is more reductionist. However, memory isnt perfect. No human has control over their memory no matter how good or bad question, which meant that there was less chance of demand characteristics. The term ecological validity means whether or not you can generalize the results from a study to real life The overall aim for the study that Loftus and Palmer carried out was to investigate whether changing the phrasing of Dependent Variable: the participants estimate of the speed of the cars when the they collided. Take for example a study in which a person has to take an IQ test, that returns the result that they have below average intelligence. PDF 1. 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. They were asked specific questions, such as About how fast were the cars going when they (smashed/collided/bumped/hit/contacted) each other?. What was the hypothesis of the car crash experiment? Why was Loftus and Palmers study artificial? people may have not even been looking whistle watching the video and gave a random answer. They suggest these two sources of information work together to create the memory, which is what they suggest happened in their second experiment to lead some participants to believe that there was broken glass. Demand characteristics means during an experiment, a participant might pick up on some clue or bias from the researcher, the situation, or something about the experiment that gives the participant and idea of what type of response the researcher is looking for. This implies that misleading information may have a greater influence in the lab rather and that Loftus and Palmers study may have lacked ecological validity.

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. Participants who were asked the smashed question thought the cars were going faster than those who were asked the hit question. Illustrate your results in either a table or graph. In order to best understand this study, it is highly recommended that you first read the following books written by Elizabeth Loftus: Eyewitness testimony is a form of evidence used in the court systems.

Even though we Define EWT EWT is an important area of research into cognitive psychology and memory. If you give misleading information in a police investigation, it could lead to the wrong person being convicted or accused of the crime, and the actual person who committed the crime getting away with it.
