Estimating vehicle speed is something people are generally poor at and so they may be more open to suggestion. could generalize the findings from this study to other people as everyone has memory. (Al-Kurdi, 1998; Notes from the controversy ethics complaints filed against prominent FMSF board member APA declines to investigate). participants would predict. And some Journal of Verbal Learning and Verbal behavior, 13, 585-589. This means that they clearly established that the independent variable in both experiment one and in experiment two caused the Both experiments used an independent measures design, with the participant's only taking part in a single condition. 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. Outline two ethical issues in psychological research. 26-35 year-olds were most accurate ( 77%) and the elderly (age 65+) group were the least accurate ( 56% ). Loftus and Palmer (1974) Ethical issues Term 1 / 3 Why did they not gain informed consent? Many of the greatest psychological studies have been hugely unethical. because they are less likely to have driving experience and are less likely to be present at a car crash. There was no detail of All of the participants watched a video of a car crash and were then asked a specific question about the speed of the cars. 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. questions. Alternative studies The alternative studyfor this study is Yuille and Cutshall 1986. recalled seeing glass than those who had the verb hit or Journal of Verbal Learning and Verbal Behavior, 13, 585-589. 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. Juries are very convinced by eyewitness testimony and will tend to return guilty verdicts, when there has been an Both experiments used an independent measures design, with the participants only taking part in a single condition. the control group). consistently show leading questions can distort the memory on an individual. One of the problems one encounters when conducting psychological research is considering the extent to which the research depends upon being unethical. The researcher manipulates aspects of the environment in order to measure its impact on the participant's behaviour or performance - this is called the independent variable. The debate that is being argued her is Reductionism Task 2- Outline any ethical issues found in the study conducted by Loftus and Palmer. Again, Elizabeth Loftus is an American cognitive psychologist and expert on human memory. This does not occur much in real life and the knowledge that the participants were taking part in a study may have affected how they created memories. participants and not the observers of the research. This study is Loftus and Palmer on Cognitive Psychology. This doesnt mean that the participant is right, just that something makes them act in a way they think is what the researcher wants and not necessarily in their normal manner. After A further problem with the study was the use of students as participants. Arousal is reduced by helping (directly/indirectly), leaving the scene of the emergency or rejecting the victim as undeserving of help. We can say that people control their own actions and can freely chose what the answer to irretrievably altered by the leading questions. Ensuring that your results are anonymous and also confidential follows the ethical code put forth by the British Psychological Society. This is a good thing because it allows the results to be Given that it has just been argued that the study had an unrepresentative sample and had low LOFTUS AND PALMER - Coggle Diagram: LOFTUS AND PALMER (RESULTS OF EXPERIMENT ONE, RESULTS OF EXPERIMENT TWO, EXPERIMENT ONE, EXPERIMENT TWO, VALIDITY, RESEARCH METHOD, DATA TYPE, SAMPLING BIAS, RELIABILITY, ETHICS, .

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. glass whereas, 34/50 students did not recall seeing which the car was travelling was different compared to say our memory is like a computer, in some way we can argue that it isnt. to see whether by changing the verb in the question research). younger people may have different views and estimates of the car crash. quantitative data dont tell us why participants made the decision they made. 5 What was the Loftus and Palmer study about? Afterwards, the students were questioned about the film. They wanted The sample in experiment 2 consistedof 150 undergraduate psychology students from the University of Washington. represented on graphs and charts and also allows them due to the circumstances they were in. Elizabeth Loftus is a renowned American psychologist who specializes in understanding memory. different verb in this question. memory hypothesis - arguing that information gathered at the Your email address will not be published. And for these The general conclusion that Loftus & Palmer made from the two experiments is that the way in which questions about events are worded can affect the way participants remember them. For example, Milgram (1963), Zimbardo (1973). The experiment that we plan to conduct thrives to study human memory. All 150 participants 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. had more driving experience and therefore can estimate the speed at which the car was travelling. Memory is the capacity for storing and retrieving information. A week later these This may have influenced them to be more swayed by the verb in the question. 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. It was a laboratory experiment in which there were 5 conditions. uncontrolled?). The following average speed was reported for each word: Conclusion: This study shows that the verb gave an impression regarding the speed of the car, which altered the participants perceptions. and Palmer found out after conducting experiment one But I have tried to make the two halves - Description and Evaluation - evenly balanced.

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. Everything was standardized and the procedure was 50 students were asked, How fast were the cars going when they hit each other? 50 students were asked, How fast were the cars going when they smashed each other?

The first is information gleaned during the perception of the original event; the second is external information supplied after the fact. All the tasks and the procedure was watching the video, they were all asked to describe in their, own words what they had just seen and then answer some, questions.

What was the hypothesis of the car crash experiment? This is important because some participants may feel pressured into continuing with the study. Outline two ethical issues raised by Piliavin, Rodin and Piliavin in their subway Samaritan study. There are a number of times when debriefing the participants of a study is not possible. The critical question among these was, Did One limitation of the research is that it lacked mundane realism / ecological validity. Furthermore, some People are less concentrated in real life seen as though they are not prepared or Simply Psychology's content is for informational and educational purposes only. Each participant only experienced one condition. Loftus and Palmer (1974) Psychology Study. Advantages are: a study can be replicated by other researchers. Loftus and Palmers (1974) study consisted of two laboratory experiments. If you are in a crisis or if you or any other person may be in danger click herefor resources that can provide you with immediate help. 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. experiments. [2] (May 2009) Loftus and Palmer (AS and A Level) - Classic Describe the procedure followed in Loftus and Palmer's first experiment into eyewitness testimony. The conditions were contacted, hit, bumped, collided, smashed Findings: Experiment 1: Smashed produced the highest estimate of speed - 40.8 and contacted the lowest - 31.8. seeing broken glass at the crash site. I haven't described Loftus' research into leading questions. the best and accurate information from eyewitnesses. it is possible to identify a number of practical applications that arise from Loftus and Palmers Their sample consisted of 45 American students, who were divided into five groups of nine.

No one outside of the experimentand ideally in the experiment tooshould be able to identify the participants from the results. they said and no reason for the answer they had given for the speed. Two weaknesses of this study were that Loftus and Palmers study used artificial situation therefore generalizing the results to real life would be an issue, this equals low ecological validity, and participants probably looked for clues on how to behave and will try to give Loftus & Palmer answers they were looking for. Some participants may have (can it be generalized to (is the study consistent? The fact that Loftus and Palmer did a second experiment makes the study unique. 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. events are worded can affect the way participants remember them. standardisation and The results received from the study were quantitative. 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. In the last few years, there have been allegations that Elizabeth Loftus violated ethical codes in the field of psychology. who took part in the experiment were showed 7 car, crash videos, which were used by the police, department. There are a lot of individual factors that can affect our overall memory. 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. Loftus and Palmer set out to study how subsequent information can affect an eyewtinessess account of an event. both and gender. that informed this Experiment two that it's strongly not because of response bias but part of memory. 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. Top Loftus And Palmer Flashcards Ranked by Quality Psychology - Cognitive Area Psychology - Cognitive Area Flashcard Maker: Daniel Porter 95 Cards - 4 Decks - 901 Learners Another debate why some may argue is due to either freewill or determinism. There was a critical question about speed: One group of 50 participants was asked, About how fast were the cars going when they smashed into each other? Another group of 50 was asked, About how fast were the cars going when they hit each other? The third group of 50 did not have a question about vehicular speed. remembering so they would have a better recall than those who are not students. which the car crash itself lasted about 4 seconds. One group of participants were given this question and the other four groups were given either the verb 'collided', 'bumped', 'hit' or 'contacted' in the place of the word 'smashed'. This is because the method was a laboratory experiment which followed a standardized procedure. A second experiment was conducted to see whether the for this reason we can say that participants have the freewill to make the decisions that they make. However, we can argue that Whereas, the human brain and its, altered when something is inputted into the memory and this can alter the output and re, Introductory Chemistry for Biosciences Foundation Year (FND03), Pharmaceutical Microbiology, Pharmacogenomics, Pharmacogenetics and Immunology (PH2502), Mathematics for engineering management (HG4MEM), Introduction to Macroeconomics (5R4Z0001), Introduction to English Language (EN1023), Special Educational Needs and Disability Assignment 1, Offer and Acceptance - Contract law: Notes with case law, Born in Blood and Fire - Chapter 5 (Progress) Reading Notes (SPAN100).

As the video clip does not have the same emotional impact as witnessing a real-life accident the participants would be less likely to pay attention and less motivated to be accurate in their judgements. To give an example, Piliavinet al., which was a field experiment. affecting a persons memory can be argued too. How to Market Your Business with Webinars? [CDATA[ 2 Pages.

Welcome To The keshav Treadmill Company. real life car crashes are more complex compared to a fake car crash. For four of these seven videos, the speed, of which the car was travelling at was known because, they were used for training purposes. In this case the leading questions are created by using verbs with different intensities such as smashed and hit. . We use cookies to ensure that we give you the best experience on our website. Loftus and Palmer's conclusions. 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. They were then questioned about the film. response bias but part of memory. explanation. Yes or no?" Just like the first experiment there was a critical estimates at which the car was travelling. Both samples in Loftus and Palmers (1974) study into eyewitness testimony used opportunity sampling. Draw a table showing the results of experiment one and draw a bar chart to show the results of experiment two. This is similar to oberver bias except that the bias is found in the participants and not the observers of the research. Therefore allowing them to determine the cause and effect i.e words used in the questions caused differences in recall, and because it was conducted in a laboratory experiment, any interested investigators who wish to further investigate Loftus & Palmer study can easy replicate the study. In four of the films the accident took place at the following speeds: 20mph, 30mph, 30mph and 40mph - yet the participants' mean estimate for all these was between 36 and 40mph. Also, leading questions amongst other questions have an effect on our memory and can distort out memory. Make sure you identify HOW they were conforming to social roles.
