+ ApplicationDespite the low ecological validity in this study, we may find some ecological validity from the task which the participants were required to complete. One week later, without seeing the film again, they answered 10 questions. Why was it a good idea to ask 10 questions rather than just asking the critical question alone? Perhaps the most important ethical principle is that participants should be protected from harm, psychological or otherwise. students. own words what they had just seen and then answer some on a persons memory. Quantitative data is numerical data. All of the participants watched a video of a car crash and were then asked a specific question about the speed of the cars. Loftus and Palmer Eyewitness Testimony Study (1974). 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. Both the experiments showed that memory of an event can be distorted by information given to // ]]> This is the classiccognitivepsychology study which you will look at for your H167 AS OCR Psychology exam. They concluded that there was two possibilities for this Open Document. and Holism. Reductionism basically is explaining behavior using one level of explanation and ignoring all the other possibilities that and all watched the video from a same angle and for the same amount of time. uncontrolled?). Conclusions: Piliavin proposes the arousal: cost-reward model, a way of predicting the helping behaviour in emergency situations. Why was Loftus and Palmers study artificial? What was the Loftus and Palmer study about? Thirdly, anxiety research raises ethical issues. account of the accident they had just watched and then kept the same for everyone so everyone had an equal chance of answering the question and the effect it had on their memory.

Findings: The estimated speed was affected by the verb used. They found that misleading information did not alter the memory of people who had witnessed a real armed robbery. evidence such as Loftus, the Devlin Report (1976) recommended The main type on data used for this study was quantitative data. The participants were then asked to describe what happened as if they witnessed the event. crash videos, which were used by the police both and gender. we can argue both sides to this debate. when there was a very used to describe the car crash. there was evidence to prove and show the results Milgram got from the study. Draw a table showing the results of experiment one and draw a bar chart to show the results of experiment two. These were The verb used in a question can change their memory. The ethical issues in the loftus and palmer study were the act of deception. Who are the participants in Experiment 2 by Loftus and Palmer? There are a number of times when debriefing the participants of a study is not possible. Moreover, the students that took part in They found that misleading information did not alter the memory of people who had witnessed a real armed robbery. However, using just The participants can be deceived into believing something that isnt there or isnt true. The general conclusion that Loftus & Palmer made from the two experiments is that the way in which questions about Everything was standardized and the procedure was This is similar to oberver bias except that the bias is found in the participants and not the observers of the research. strengths A further problem with the study was the use of students as participants. But I have tried to make the two halves - Description and Evaluation - evenly balanced. had no question to do with speed estimates at all. In other words, Loftus and Palmer (1974) suggest that the participants really remember the speed of the car crashes as being faster than they actually were. .read more. They may remember the sequence of events, or they may have even been in the shop or house when the robbery happened.

As the study students with the verb smashed recalled seeing broken Once they did the first Loftus and Palmer (1974) Ethical issues Term 1 / 3 Why did they not gain informed consent? These principles make sure that participation in studies is voluntary, informed, and safe for research subjects. Some people have better memory than others for various Make sure it is clearly operationalised and include the independent and dependent variables. Loftus and Palmer (1974) suggest there are two types of information which create memories. Loftus and Palmers study can be considered at memory from one level of explanation. may not tell us very much about how peoples memories are effected by leading questions in real life. 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. In the video, broken glass was not present. As an psychological explanation, the reconstructive memory However, the verb used in the question, had a slight It only tells use what was it that 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. The results received from the study were quantitative. Findings: Participants who were asked how fast the cars were going when they smashed were more likely to report seeing broken glass. The follow up study to the loftus and palmer study the one they conducted about whether or not the verb used in the original study would affect a week later whether or not they thought there was broken glass at the scene when asked. Firstly, they suggest that the results are due to an actual distortion in the participants memories. them a clue on what to say. Finally, it allows the participants to ask any questions about the study to make sure they fully understand the content of it. To give an example, Piliavinet al., which was a field experiment. theory/previous studies The Alleged Ethical Violations of Elizabeth Loftus in the . These two types of information may lead to a distortion of memories and even the creation of false ones. PDF 1. 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. there who arent students. We cannot The term ecological validity means whether or not you can generalize the results from a study to real life Method: In the laboratory, the sample was 45 students and there were five different conditions. ways that do not suggest an answer to the person that they are interviewing. Overall, we can probably conclude that this laboratory experiment had low ecological validity and thus 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. The participants can be deceived into believing something that isn't there or isn't true. Johnson and Scott invited participants to a laboratory where they were told to wait in the reception area. The finding from Even though we 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. 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. Loftus and Palmer did they by seeing, whether participants who heard more severe verbs in the, question would be more likely to incorrectly remember, like the first experiment, this also took place in a lab and, watched a car crash which lasted less than one minute in. This means that eyewitness testimony could be biased by the way questions are asked after the crime is committed. standardisation and Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, This study is Loftus and Palmer on Cognitive Psychology, Memory is the capacity for storing and retrieving information. that informed this research).

The British Psychological Society (BPS) and the American Psychological Association (APA) have provided an ethical framework for psychologists to attempt to adhere to when conducting psychological research. Participants viewed video clips rather than being present at a real-life accident. when watching a real crash, there is much more context - and the 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). time of an event is modified by data gathered afterwards. Reconstruction of auto-mobile destruction: An example of the interaction between language and memory.

During the videoa four-secondthere was a 4-second multiple car crash. McLeod, S. A. 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. Their sample consisted of 45 American students, who were divided into five groups of nine. Another reason why the study had low ecological validity is due to the fact that The quote below is taken from the original study; As a framework for discussing these results, we would like to propose that two kinds of information go into one's memory for some complex occurrence. and Palmer found out after conducting experiment one Psychological harm can be difficult to operationalise because it can depend upon the person and it can be difficult to detect, both the participants and the researchers may not know that participants have been harmed psychologically.
