Calculate the mean, median and mode speed estimates for both the 'smashed' and 'hit' conditions. Loftus and Palmer (1974) Researchers showed participants film clips of actual car accidents and then gave them a series of questions to answer. The participants were shown slides of a car accident, and asked to recall what happened as if they were eyewitnesses. The War Of The Ghosts study by Bartlett was not at all scientific. There was none shown in the slides. The hypothesis is that the verb 'smashed' in the question . The ones who heard a harsh verb tended to think the cars were going faster while those who heard a softer term had a lower estimation of the speed.

Overall, we can probably conclude that this laboratory experiment had low ecological validity and thus Students are not representative of the general population in a number of ways. Her main focus has been on the influence of (mis)leading information in terms of both visual imagery and wording of questions in relation to eyewitness testimony. function Gsitesearch(curobj){curobj.q.value="site:"+domainroot+" "+curobj.qfront.value}. Perhaps the greatest strength of Loftus and Palmer's experiment is the degree of control over confounding variables. Weakness- doesn't give details that could increase the validity of the study, Loftus and Palmer - Evaluation - reliability, High reliability as tests were standardised and controlled, Loftus and Palmer - Evaluation - validity, Low population as students were similar age This implies that misleading information may have a greater influence in the lab rather and that Loftus and Palmer's study may have lacked ecological validity. However, despite the points made above, Loftus and Palmer conducted a lab experiment in which 45 students were shown films of traffic accidents, followed by a series of questions about how fast the.

A further problem with the study was the use of students as participants. The first is the information obtained from perceiving the event, and the second is the other information supplied to us after the event. loftus and palmer strengths and weaknesses. 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. Estimating vehicle speed is something people are generally poor at and so they may be more open to suggestion. INTRODUCTION The accuracy of memory has been studied at length. Loftus and Palmer argue that two kinds of information go into a person's memory of a complex event. One strength of the experimental method used in Loftus and Palmer's study is that it had high controls, all participants were exposed to the same video clip, this Cebollada, L., Violeta, I., & Horno Chliz, M. D. C. El efecto del lenguaje en el recuerdo de eventos recientes: explicaturas, presuposiciones e implicaturas. Participants' speed estimates were faster than reality. Precisely what the data from Loftus and Palmers experiment supported is that a persons perception of reality and memory can be subtly altered. Below are two examples of studies conducted by Elizabeth Loftus (a key researcher in EWT) that provide evidence of these sources of misleading information. . ; Palmer ( 1979 ) uses a scientific method supplied to us the. Loftus and Palmer conducted a laboratory experiment which allowed them to control specific variables in order to identify cause and effect relationships. Court room procedures However, the verb used in the question, had a slight impact on the estimate speed. Describe the experiment by Loftus & Palmer (1974). Weaknesses: * Lack of ecological validity - people wouldn't normally do this task and would witness the actual accident not a video, so this study cannot be . Importantly they may be less experienced drivers and therefore less confident in their ability to estimate speeds. 11.

Use a graphing calculator to check your answers to Exercises 11, 31, 41, and 59. loftus and palmer strengths and weaknesses They aimed to show that the cues within leading questions could distort eyewitness testimony accounts. Perhaps the greatest strength of Loftus and Palmer's experiment is the degree of control over confounding variables. Theyre obviously aware that the language they use to describe them has a significant influence on the receivers and they use it to favor the interests they serve. It is very common for hiring managers to ask about your strengths and weaknesses during a job interview. A second weakness of Loftus and Palmer's research is that their study lacks population validity. As this was a field experiment, the participants did not know they were part of a study, so they had no demand characteristics. What were the results and implications of their findings? 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. In this study 9 participants were randomly allocated to one of the 5 conditions, based on the verb used to ask the leading question: smashed, collided, bumped, hit, and contacted.

Good reliability as if they repeated the experiment they should get the same or similar results. Laboratory experiment. 3.1 The Misinformation Effect. Essay on Loftus and Palmer argue that what they hear after the event what is +! Clearly linked to the classic research. One critical question. Conclusion: 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. Research in the early 1970s, led by cognitive psychologist Elizabeth Loftus, brought attention to the reliability of eyewitness testimonies, demonstrating that an interviewer could influence interviewees' responses by manipulating the phrasing of a question. For example, in describing Loftus & Palmer's (1974) study, it was necessary to link it back to schema theory as an explanation of why the memory was . copy). cheapest club membership in chennai . No because in 4 of the films, the speeds were: 20mph, 30mph, 30mph and 40mph yet P's estimated speeds between 36mph and 40mph. irretrievably altered by the leading questions. For example, providing information like how fast the vehicles were traveling and how much damage was caused. Marks AO3 10 A thorough evaluation. Their two experiments consisted of 45 and 150 American students. But can be seen as high ecological validity because she used real life car crash videos, No ethical issues . 7. Key Theme: Attention . She has conducted research on the malleability of human memory. Loftus & Palmer (1974) The researchers wanted to study the phenomenon known as reconstructive memory. People ( e.g scientific method this suggests that leading questions ) population West Game Troop Ratio, Collided - 39.3 Highly reliable. One limitation of the research is that it lacked mundane realism / ecological validity. Findings: Participants who were asked how fast the cars were going when they smashed were more likely to report seeing broken glass. 806 8067 22, Registered office: International House, Queens Road, Brighton, BN1 3XE, Strengths + Weaknesses of Cognitive Psychology, Eye Witness Testimony of Misleading information / Post event information, Studies of the accuracy of eyewitness testimony, Can someone mark my answer to a exam question i have done? Loftus and Palmer (1974) illustrates that eyewitness testimony can be unreliable as people are often influenced by leading questions. . All volunteers watched the same video during the experiment and yet each one of them remembered it in a significantly different way. How do you think this may have effected their behavior? So if you're doing Loftus and Palmer for the IA, read this post carefully. However, this was in lab conditions. They don't replace the diagnosis, advice, or treatment of a professional.

Aims: To test the hypothesis that the language used in eyewitness testimony can alter memory. Students viewed a short one minute clip- contained multiple car accidents. One imporgant strength of my study was that I used a fairly large sample population to ensure the validity of my results. After watching the film participants were asked to describe what had happened as if they were eyewitnesses. They were then asked specific questions, including the question About how fast were the cars going when they (smashed / collided / bumped / hit / contacted) each other?. Tips! A thief entered a gun shop, tied up the owner, and stole money and guns.

Hit- 7 Yes / 43 No (LogOut/ In a typical misinformation effect study, participants witness an event, usually visually via slides ( Loftus & Palmer, 1974) or a video . For example, Loftus and Palmer found eye witness recall was easily susceptible to misleading information and would provide inaccurate information as a result of this. The central goal of Loftus and Palmer's experiment was to establish the extent to which language influenced the perception of reality. A case study of eyewitness memory of a crime. Loftus Generally 1.4. strengths and weaknesses (table 1.2). Stretch Film Division. This was a laboratory experiment with five conditions, only one of which was experienced by each participant (an independent measures experimental design). Hit - 34.0 It required a sample of 45 student volunteers. . - The question was manipulated as it was very controlled, as it did not word the questions in such a way as to suggest. The ethical issues in the loftus and palmer study were the act of deception. There were some very good responses to this question; however, many candidates simply described a study of the reliability of memory but did not explain it. In this and other publications (Loftus et al., 1975; Loftus & Zanni, 1975), Loftus and her colleagues have demonstrated that, at a minimum, postevent questioning Evaluation: This is a weakness because it can be argued that the findings from artificial laboratory research settings such (as Loftus' study) may not be applicable to real life EWT behaviour, which weakens the research as support for the role of misleading information affecting the accuracy of EWT. Research on the misinformation effect has a long and rich history in the human memory literature, beginning with the pioneering work of Loftus (1975; Loftus & Palmer, 1974 ).
