Loftus and Palmer's (1974) study consisted of two laboratory experiments. In the study Loftus only used students to study memory distortion. , OCE A2 psychology predictions for core studies??? Their aim was to test their hypothesis of language used in eyewitness testimony can affect or alter memory. - The question was manipulated as it was very controlled, as it did not word the questions in such a way as to suggest. 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 ). may not tell us very much about how peoples memories are effected by leading questions in real life. Strengths and weaknesses Strength: -Quantitative data: was collected which made it easy to make comparisons bewtween groups - Cause and effect was established. Strengths + A Lab experiment was used which had high control and thus allowed for the accurate measurement of variables, thus more objectivity . Weakness The study only used university students. Related November 15, 2017 Two weaknesses of this study were that Loftus and Palmer's 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 real life, there may be consequences arising from the answers that you give and this may put Yuille and Cutshall investigated 13 people who had witnessed an armed robbery 4 months previous to the experiment. The Loftus and Palmer study is one of the most interesting experiments ever conducted in psychology. Their two experiments consisted of 45 and 150 American students. loftus and palmer strengths and weaknesses. In Experiment 1, a conceptual replication [Loftus, E. F., & Palmer, J. C. (1974).

Participants who were asked the smashed question thought the cars were going faster than those who were asked the hit question. , OCE A2 psychology predictions for core studies??? Background. Loftus and Palmer conducted a laboratory experiment which allowed them to control specific variables in order to identify cause and effect relationships. Experiments cannot always replicate real-life factors and influences. 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. 1.3.3 Strengths And Weaknesses Of Behaviourist Approach (Be) 1.3.2 Effectiveness & Ethics Of Sd (Be) 1.3.4 Classical Research Little Albert For example, they may be required to give a description of a robbery or a road accident someone has seen. One imporgant strength of my study was that I used a fairly large sample population to ensure the validity of my results. Like any question, your response holds weight. Read on to learn more about this! Strengths: Strict control over variables --> to determine cause & effect relationship Limitation: Lacks ecological validity Laboratory setting artificial environment Task does not reflect daily activity Connection of study to question They may remember the sequence of events, or they may have even been in the shop or house when the robbery happened. Zealous conviction is a dangerous substitute for an open mind.. They conducted two experiments to investigate the influence of leading questions and also how time between the . There was no broken glass on the original film. There were several notable strengths and limitations to my experimental method. Your memory can betray you. 875. Tap card to see definition . Schema theory (Theorist: Frederic Bartlett) Mental representation of knowledge created over time from previous experiences. The conclusion were that 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. loftus and palmer strengths and weaknesses. Calculate the mean, median and mode speed estimates for both the 'smashed' and 'hit' conditions. Not everyone will think like a student. There was a large sample size of 4550 participants, so the study results are generalisable . Thus, they aimed to show that leading questions could distort eyewitness testimony accounts and so have a confabulating effect, as the account would become distorted by cues provided in the question. This may have influenced them to be more swayed by the verb in the question. Later, Elizabeth Loftus went on to prove it was possible to go further by inducing memories. Loftus & Palmer (1979) is a good example of a lab experiment with an independent groups design. A thief entered a gun shop, tied up the owner, and stole money and guns. Competitors The Australia foodservice market is projected to reach USD 80.7 billion by 2025, witnessing a . There are many different research designs that a researcher can choose from when planning their experiment. Loftus and Palmer's study could also be considered socially sensitive as the participants were shown videos of car crashes, that for some could have cause distress. Background. The general public court scenario ) ; participants in research may be more: - Laboratory may! Reconstruction of auto-mobile destruction: An example of the interaction between language and memory. As the study was lab-based, the researchers could ensure that a range of factors (age of participants, incident viewed, environment, etc). Thus, the procedure for collecting witness testimony has changed a lot since then. Jim Acosta Book Sales, Loftus & Palmer tested participants again a week later, asking them if there was any broken glass in the film clip. A second weakness of Loftus and Palmer's research is that their study lacks population validity. Reconstructive memory is where two kinds of information go into a persons memory of an event. In the early experiments on the misinformation effect(see, e.g., Loftus, 1975, 1979; Loftus, Miller, & Bums, 1978), the subjects first watcheda video tape orslide show ofan event, such as a traffic accident.

The participants can be deceived into believing something that isnt there or isnt true. The conclusion that leading questions can affect memory has important implications for Consequently, Loftus and Palmer support the reconstructive These could include: Strengths Useful. In an experiment, you may well expect to be asked questions about what you are watching and this (oates 2012 p.118) this suggests that the model had an effect on the child's actions because all variables other than the independent variable are controlled.due to variables being Another strength of cognitive approach is theories have been applied to many cognitive therapies such as Rational Emotive Therapy. After each video clip participants were given a questionnaire which asked them to describe the accident and then answer specific questions about the accident, including the one critical question: About how fast were the cars going when they smashed each other?. It gave rise to the theory of the disinformation effect, a phenomenon that occurs with crime witnesses. (1995) We often think of memory as being like a video tape that we can wind back and replay as often as we like.

Loftus & Palmer tested the reliability of eye witness testimony. The tasks are not usually expected on real life, for instance you would not be normally asked to recall a short film. It was a laboratory experiment in which there were 5 conditions. Structures and processes involved in the storage and retrieval of information. Words exert an impressive influence on the way people process or retrieve facts from their memory. Nice work! 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. Bandura et al, Skinner & Loftus and Palmer.In order discuss and come to a conclusion as to why ecological validity is . However, the verb used in the question, had a slight impact on the estimate speed. Loftus, E. F., & Palmer, J. C. (1974). state quarters list by year state quarters list by year.

Why was each group of participants shown the 7 video clips (of car accidents) in a different order? Importantly they may be less experienced drivers and therefore less confident in their ability to estimate speeds. 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. Quantitative data so objective and no interpretation required. . 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. Tap again to see term . Loftus and Palmer found out after conducting experiment one is that the estimate speed at which the cars were travelling was not affected by the actual speed of the car. The specific verb did cause a specific memory. Conclusion: The results show that the verb conveyed an impression of the speed the car was traveling and this altered the participants' perceptions.

He was especially interested in the characteristics of people whom he considered to have achieved their potential as individuals. Loftus findings seem to indicate that memory for an event that has been witnessed is highly flexible. If someone is exposed to new information during the interval between witnessing the event and recalling it, this new information may have marked effects on what they recall. The original memory can be modified, changed or supplemented.var cid='9865515383';var pid='ca-pub-0125011357997661';var slotId='div-gpt-ad-simplypsychology_org-medrectangle-3-0';var ffid=2;var alS=2021%1000;var container=document.getElementById(slotId);container.style.width='100%';var ins=document.createElement('ins');ins.id=slotId+'-asloaded';ins.className='adsbygoogle ezasloaded';ins.dataset.adClient=pid;ins.dataset.adChannel=cid;if(ffid==2){ins.dataset.fullWidthResponsive='true';} Loftus and Palmer (1974) reconstruction of automobile destruction- Critical Review Overview of study .

Likewise, language shapes memories. *Weakness- can't be generalised as not everyone is a student low population validity, Quantitative- strengths- objective data = easy to analyse and compare Make sure it is clearly operationalised and include the independent and dependent variables. 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. Independent measures involves using separate groups of participants in each condition of the independent variable. 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. 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 unreliable. Conduct your own study repeating one of the experiments by Loftus and Palmer. 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.

Articles and opinions on happiness, fear and other aspects of human psychology. 2012 2023 . A second weakness of Loftus and Palmer's research is that their study lacks population validity. 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. 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. This week I am going to be exploring this type of experiment and underlining why I believe the weaknesses of laboratory experiments outweigh the strengths. This means that the tasks may lack mundane realism. 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.

List of Weaknesses of Cognitive Psychology 1. A weakness of the cognitive approach is that, as lab studies are used, there is a lack of ecological validity with this research and so cognitions are being tested artificially. It does not allow for direct observation. For example, providing information like how fast the vehicles were traveling and how much damage was caused. Unfortunately research shows that our memories are not as stable or as accurate as we think they are.
