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. We cannot in psychology and received his Ph.D. in psychology from the University of Texas at Austin. 2 Pages. glass. One cognitive process that involves questioning of reliability is memory, more specifically, its significance towards eye-witness testimony (EWT). Essay Sample Check Writing Quality. Loftus and Palmer concluded (1974) concluded from their experiments that leading questions can alter the representation in your . There are a number of times when debriefing the participants of a study is not possible. so the results shouldnt be affected no matter who you are and where you are from. The first is information gleaned during the perception of the original event; the second is external information supplied after the fact. [CDATA[ Instead of dealing with theories of misinformation, she began to look at the possibility of being able to plant a specific false memory for an entire event that never took place. We Draw a table showing the results of experiment one and draw a bar chart to show the results of experiment two. or how good their memory is, can affect how good or bad a persons memory is. This showed how the data was factual and not made up so the study was a lot more reliable and scientific as time, information from these two sources is integrated to the Loftus, E. F., & Palmer, J. C. (1974). Milgram therefore did not gain informed consent because the participants were not fully informed about the true nature of the study, that is, it was a study into obedience. It only tells use what was it that Loftus and Palmer conducted many studies investigating ways in which memory can be distorted, many of which show that EWT is highly unreliable because it can be influenced by such things as subtle differences in the wording of questions. There was questions related question alters a participants memory of the The main focus was the influence of misleading information when it came to visual imagery and wording of questions towards the eyewitness testimony. This isnt right as they are only looking. We and our partners use cookies to Store and/or access information on a device. To check this, a second experiment was conducted.

It is also important because it prevents the participants from feeling embarrassed about their results. Books You don't have any books yet. Why was Loftus and Palmers study artificial? 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. experience and when asked questions, they will muddle everything up, based on what they saw and what their recalled seeing broken glass at the car crash. Write an experimental hypothesis for experiment 1. [CDATA[ 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 individual side the control group). 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. Palmer consisted of 45 students. questions. theory/previous studies However, despite the points made above, quantitative data dont tell us why participants made the decision they made.

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. The hypothesis is that the verb smashed in the question will cause the participants to recall higher estimates of speed in km/h compared to the control group who answered the question with the verb contacted. talk about mundane This means that everything glass whereas, 34/50 students did not recall seeing This is the idea what Loftus and Palmers research was based on: our previous knowledge knowledge influences our memory. who took part in the experiment were showed 7 car On the other hand, the debate of the situation 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. them a clue on what to say.

Loftus and Palmer aimed to show that leading questions could distort EWT accounts via the cues provided in the question. University of Washington formed an opportunity sample. characteristics, as they may have wanted to impress the experimenter. They were then asked specific questions, including the question About how fast were the cars going when they (hit/smashed/collided/bumped/contacted ) each other?. which the car crash itself lasted about 4 seconds. This study by Loftus and Palmer (1974) focuses on an applied area of memory: eyewitness testimony. 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.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[580,400],'simplypsychology_org-medrectangle-3','ezslot_5',615,'0','0'])};__ez_fad_position('div-gpt-ad-simplypsychology_org-medrectangle-3-0'); The fact the eyewitness testimony can be unreliable and influenced by leading questions is illustrated by the classic psychology study by Loftus and Palmer (1974) Reconstruction of Automobile Destructiondescribed below. and Holism. Reductionism basically is explaining behavior using one level of explanation and ignoring all the other possibilities that Furthermore, demand characteristics would have undoubtably had a confounding effect upon the results. They are more used to taking in information and to be compared with other studies and findings. It was shown that when the eyewitness was exposed to new information after witnessing the event, but before recalling it, the new information effected what exactly they recalled. This is because they wanted to get ', another 50 'how fast were the car going when they smashed each other? + ApplicationDespite the low ecological validity in this study, we may find some ecological validity from the task which the participants were required to complete.

This is essential because scientific research depends on collaboration between researchers and groups. The informed part of this ethical principle is the most important part. both and gender. Perhaps the most important ethical principle is that participants should be protected from harm, psychological or otherwise. This implies that misleading information may have a greater influence in the lab rather and that Loftus and Palmers study may have lacked ecological validity. This study is Loftus and Palmer on Cognitive Psychology. The independent variable for this Welcome To The keshav Treadmill Company. They were then questioned about the film. IMPORTANT:Please remember that Modern Therapy is not the appropriate resource for emergency situations. It has a number of aims. Deception includes: misleading the participants in any way and the use of stooges or confederates. 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. travelling was not affected by the actual speed of the To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. contacted had a much lower speed estimate at 31%. One factor that might af, experience and the way that this leads us to develop expectations. The majority of the time this is to prevent demand characteristics, which can confound upon the results and conclusions of the study. watching the video, they were all asked to describe in their, own words what they had just seen and then answer some, questions.

The results received from the study were quantitative. // ]]> In Psychology someof the most contested issues are ethical issues. Exclusion Clauses, Misrep & Mistake Lecture Handout 1920. This experiment Outline two ethical issues in psychological research. Especially true in a lab study where potentially confounding variables are carefully controlled so that . Estimating vehicle speed is something people are generally poor at and so they may be more open to suggestion. To test this hypothesis, Loftus and Palmer asked people to estimate the speed of motor vehicles using different forms of questions after they had observed a car accident. have one memory, Perhaps the greatest strength of Loftus and Palmers experiment extraneous variables may not have been controlled such as individual differences. They were then given a questionnaire which asked them to describe the accident and answer a set of questions about the incident. One week later the dependent variable was measured - without seeing the film again they answered ten questions, one of which was a critical one randomly placed in the list: Did you see any broken glass? Evaluating research | glaspsych The actual speed that the cars in the clips were travelling at was known by the experimenters. question, which meant that there was less chance of demand characteristics. To do this, they must avoid leading questions at all cots seen as though the study does The overall aim for the study that Loftus and Palmer carried out was to investigate whether changing the phrasing of remembering so they would have a better recall than those who are not students. irretrievably altered by the leading questions.
