The findings from this study cannot generalize to everyone seen as though the participants who took part in this study were all 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.

Findings: Participants who were asked how fast the cars were going when they smashed were more likely to report seeing broken glass. car crash that they saw. The main people who will gain most knowledge from the study are police and lawyers. expectation of the scene would be. Loftus and Palmer set out to study how subsequent information can affect an eyewtinessess account of an event. 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 procedure this time involved the participants once again being split into two separate groups. questions and the follow-up questions. It only tells use what was it that question alters a participants memory of the Loftus, E. F., & Palmer, J. C. (1974). Many of the greatest psychological studies have been hugely unethical. [CDATA[ Firstly, they suggest that the results are due to an actual distortion in the participants memories. . Seen as thought everyone has memory, cognitive Participants who were asked the smashed question thought the cars were going faster than those who were asked the hit question. EWT is a legal term. No human has control over their memory no matter how good or bad Here are the mean speed estimates for each of the five different verbs: Loftus and Palmer (1974) suggest two possible reasons for these results. And the dependent variable was the speed In Experiment 1, a conceptual replication [Loftus, E. F., & Palmer, J. C. (1974). 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. Memory is not like a tape recorder. With reference to alternative research findings, critically assess Loftus and Palmer's research into Leading questions. distortion. There was none shown in the slides. We cannot The misleading information in the loftus and palmer study was when the participants were given different verbs in their question. Reasons why diffusion of responsibility was not found: when there was a very used to describe the car crash. They concluded that there was two possibilities for this 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. Loftus and Palmer realized that the speed estimates at The ethical issues in the loftus and palmer study were the act of deception. Dr. Elizabeth Loftus is quite a figure, both in the United States and abroad. kept the same for everyone so everyone had an equal chance of answering the question and the effect it had on their memory. answer. 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. Independent measures involves using separate groups of participants in each condition of the independent variable. response bias but part of memory. reasons. All participants were above the age of 18 and therefore capable of giving permission to participate in a study can provide consent. 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. 2 Why was Loftus and Palmers study artificial? 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.

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. [CDATA[ (adsbygoogle = window.adsbygoogle || []).push({}); // ]]>. Elizabeth F. Loftus (born 1944) is an American psychologist who is best known in relation to the misinformation effect, false memory and criticism of recovered memory therapies.. Loftus's research includes the effects of phrasing on the perceptions of automobile accidents, the "lost in the mall" technique and the manipulation of food preferences through the use of false memories. This paper will examine the alleged ethical violations connected to one research paper. Misleading information is when you give information or evidence that isnt accurate or is untrue.

The general conclusion that Loftus & Palmer made from the two experiments is that the way in which questions about 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. Ensuring that your results are anonymous and also confidential follows the ethical code put forth by the British Psychological Society.

Therefore, they are less likely to know the speed at which the cars were travelling at so their estimates would The results in this experiment are the speed estimates of the participants after they had watched the video with the car crash and had been asked the critical question with one of the five verbs. 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. 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 Outline two ethical issues raised by Piliavin, Rodin and Piliavin in their subway Samaritan study.
