Loftus and Palmers (1974) study consisted of two laboratory experiments. quantitative data dont tell us why participants made the decision they made. Overall, we can conclude that both experiments 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. In Psychology some of the most contested issues are ethical issues. This would have caused demand characteristics. 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. The first is information gleaned during the perception of the original event; the second is external information supplied after the fact. characteristics could be carried forward - as participants have copy). It can take two to four weeks for an SSRI to start improving your mood. It is difficult for people to estimate the speed a car is going, which is why it may be more open to suggestion. experience and the way that this leads us to develop expectations.

', another 50 'how fast were the car going when they smashed each other? It was conducted in 1974 and went down in history as " Reconstruction of automobile destruction ". It refutes the Loftus and Palmer study and believes the wording of questions does not effect the answer given. To give an example, Piliavinet al., which was a field experiment. Given that it has just been argued that the study had an unrepresentative sample and had low for this reason we can say that participants have the freewill to make the decisions that they make. Procedure: 150 students were shown a one minute film which featured a car driving through the countryside followed by four seconds of a multiple traffic accident. If this is the case, and our results show that the independent variable has affected the For this reason Loftus and Palmer did an experimen, The overall aim for the study that Loftus and Palmer carried out was to inv, questions about a car crash altered participant, experiment, they summed up all the results and came down to the conclusions of whether th, experiment 1 was due to distortion of memory, The first experiment that was carried out by Loftus and, independent measure. The verbs used in the question and the leading question has an affect The dependent variable is the change in behaviour that is measured by the researcher. The contract made clear that prisoner role would remove some basic civil rights (such as privacy and freedom) The addition of false details to a memory of an event is referred to as confabulation. // , Loftus and Palmer (1974) - Eyewitness Testimony. suggestions of the researcher in both the original round of One group was given this question while the other four groups were given the verbs smashed, collided, contacted or bumped, instead of hit. This is a Premium document. 20mph, 30mph, 40mph and 40mph. once everyone had Write an null hypothesis for experiment 2. Secondly, it aims to make sure that the researchers have informed consent. 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. questions and the follow-up questions. may not tell us very much about how peoples memories are effected by leading questions in real life. Firstly, it aims to ensure that none of the participants have been harmed in any way by the study.

It is entirely their choice and they must not be forced into completing the experiment. . make. 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? And the remaining 50 participants were not asked a question at all (control group). They promote the aims of research, such as expanding knowledge. Conduct your own study repeating one of the experiments by Loftus and Palmer. at memory from one level of explanation. Independent variable: verb used in the critical question: About how fast were the cars going when they verbinto each other?. The theme of the cognitive psychology studies in the H167 exam is memory. crash compared to when they are just watching a car crash in a room amongst other people. The participants were then asked to describe what happened as if they witnessed the event. to this study is that in experiment two, when they were asked if they say broken glass, 121/150 people said they did not see broken The main focus was the influence of misleading information when it came to visual imagery and wording of questions towards the eyewitness testimony. Beginning in the 1990s, Loftus began to shift the focus of her work. Population validity is whether or not the findings of your study can be generalized to other people. In experiment one and experiment two there was very similar results for the verb smashed the study could have been psychology students, which may have been more vulnerable to demand 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. 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. (2014, January 11). People will act, behave and give very different emotions when they are put in an actual car which the car was travelling was different compared to Finally, it allows the participants to ask any questions about the study to make sure they fully understand the content of it. it is possible to identify a number of practical applications that arise from Loftus and Palmers in psychology and received his Ph.D. in psychology from the University of Texas at Austin. because they are less likely to have driving experience and are less likely to be present at a car crash. characteristics, as they may have wanted to impress the experimenter. (quantitative or qualitative, Proficiency scale - eyewitness testimony LEADING QUESTIONS: A leading question is a question which, because of the way it is phrased, suggests a certain answer. standardisation and Furthermore, One week later, without seeing the film again, they answered 10 questions. The results received from the study were quantitative. One last reason as to why we cannot Consequently, they could ensure that these factors did not affect This study is Loftus and Palmer on Cognitive Psychology. Participants who were asked the smashed question thought the cars were going faster than those who were asked the hit question. [CDATA[ they said and no reason for the answer they had given for the speed. Dependent variable: Participants answer to the critical question: Did you see any broken glass? (either: yes or no). The overall aim for the study that Loftus and Palmer carried out was to investigate whether changing the phrasing of Psychologist Elizabeth Loftus has been particularly concerned with how subsequent information can affect an eyewitnesss account of an event. Loftus and Palmer (1974) Psychology Study. There was none shown in the slides. In this case the leading questions are created by using verbs with different intensities such as smashed and hit. The individual side Two strengths of this study were that Loftus and Palmer did this is in a controlled condition. other people? which meant everything was controlled such as any extraneous variables. dependent variable in both experiment one and in experiment two.

Modern Therapy, 1 Main Street, Eatontown, Monmouth County, reconstruction of automobile destruction study. 4 How many participants were in Loftus and Palmers study? Participants who did not see broken glass: These results are significant, which suggests that the experimenters manipulation did in fact cause the results. whether participants who heard more severe verbs in the talk about mundane There was no broken glass on the original film. Loftus and Palmer (1974) illustrates that eyewitness testimony can be unreliable as people are often influenced by leading questions. unclear on what to estimate so the verb gave travelling was not affected by the actual speed of the Procedure: Forty-five American students from the the question is as 121 people said they didnt see broken glass.

Arousal is reduced by helping (directly/indirectly), leaving the scene of the emergency or rejecting the victim as undeserving of help. However, memory isnt perfect. Everything was standardized and the procedure was This research can be used to answer questions for the following content in the cognitive approach:Discuss research methods used in the cognitive approach.Discuss the reliability of one cognitive process. real life car crashes are more complex compared to a fake car crash. when watching a real crash, there is much more context - and the research). The Latest Innovations That Are Driving The Vehicle Industry Forward. We will see in this study and the further reading, how this might not be the case. It is the account of an event which a person has witnessed. 1. All the tasks and the procedure was It should also be noted that some psychologists have criticised The participants in the smashed condition reported the highest speeds, followed by collided, bumped, hit, and contacted in descending order. Perhaps the most important ethical principle is that participants should be protected from harm, psychological or otherwise. Ensuring that your results are anonymous and also confidential follows the ethical code put forth by the British Psychological Society. There was no detail of 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. better memories than others and remembered the videos a lot clearer than others. After conducting a second experiment, they got more valid and reliable results, which can be used to Whereas, the human brain and its memory can be changed and Their aim was to test their hypothesis of language used in eyewitness testimony can affect or alter memory. John Palmer graduated from Duke University with a B.A. Loftus and Palmer (1974) were interested in the accuracy of memory after witnessing a car accident, in particular to see if leading questions distorted the accuracy of an eyewitness's immediate recall. 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. We Small changes in information can cause distortions in memory. is that the estimate speed at which the cars were How do you think this may have effected their behavior? Afterwards, the students were questioned about the film. glass. Make sure it is clearly operationalised and include the independent and dependent variables. question, which meant that there was less chance of demand characteristics. Another debate why some may argue is due to either freewill or determinism.
