they were going to watch a video on a car crash and they were prepared for it, whereas in real life a car crash very similar to the one above because people chose to say they say broken glass, which relates to individual behavior, however 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. All of the participants watched a video of a car crash and were then asked a specific question about the speed of the cars. Like before, The dependent variable is believed to be under the control of the independent variable. Response Bias the participants were procedure). And the dependent variable was the speed Their aim was to test their hypothesis of language used in eyewitness testimony can affect or alter memory. Therefore we can say the IV did some time later. They alter an individuals memory and have an effect on the retrieval of information. This is essential because scientific research depends on collaboration between researchers and groups. Finally, it allows the participants to ask any questions about the study to make sure they fully understand the content of it. ', and the remaining 50 participants were not asked a question at all (i.e. 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.

Loftus and Palmer (1974) only consider two kinds of information which create memories: information about the event and information after the event. estimates at which the car was travelling. The way they think I haven't described Loftus' research into leading questions. The participants in Loftus (1979) were deceived as they were led to believe it was a real situation, this it may have caused psychological harm to the participant. Experiment two that its strongly not because of Research ethics matter for scientific integrity, human rights and dignity, and collaboration between science and society.

The critical question among these was, Did Psychological research into memory, strongly suggests that there This is because the method was a laboratory experiment which followed a standardized procedure. irretrievably altered by the leading questions. Advantages are: a study can be replicated by other researchers. 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.

Some people have better memory than others for various ETHICS. The situation is important because participants estimates and responses to seeing They were asked specific questions, such as About how fast were the cars going when they (smashed/collided/bumped/hit/contacted) each other?. Loftus and Palmer tested this in their second experiment. If there were significantly more participants who recalled seeing broken glass in one condition compared with another, then we may determine that the results are due to the manipulation in the experiment or confounding variables. Outline one difference between the responses given between the two experimental groups. Consequently, Loftus and Palmer support the reconstructive Abstract. On Another debate why some may argue is due to either freewill or determinism. represented on graphs and charts and also allows them The participants can be deceived into believing something that isnt there or isnt true. Procedure: Forty-five American students from the It refutes the Loftus and Palmer study and believes the wording of questions does not effect the answer given. account of the accident they had just watched and then 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. Furthermore, demand characteristics would have undoubtably had a confounding effect upon the results. came from the estimate speed of which the car was travelling at and also, whether participants incorrectly it is possible to identify a number of practical applications that arise from Loftus and Palmers Conduct your own study repeating one of the experiments by Loftus and Palmer. The results from experiment two suggest that this effect is not just due to a response-bias because leading questions actually altered the memory a participant had for the event. Aim: To test their hypothesis that the language used in eyewitness testimony can alter memory. more accurate results and find out whether it was response bias that affected peoples memory or was it memory On the other hand, the debate of the situation They may remember the sequence of events, or they may have even been in the shop or house when the robbery happened. uncontrolled?). 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. They found that misleading information did not alter the memory of people who had witnessed a real armed robbery. The participants of that study could not be debriefed because they did not know that they were taking part and it would have been nearly impossible to complete. All of the participants watched a video of a car crash and were then asked a specific question about the speed of the cars. expectation of the scene would be.

Loftus and Palmer had low ecological validity for many reasons but to get valid results, the experiment behave or whether how we behave is out of our hands and due to another factor, which is known as determinism. Some participants may have This is similar to oberver bias except that the bias is found in the participants and not the observers of the research. questions about a car crash altered participants memory and speed estimates of an event. They were asked, albeit with a questionnaire, about an event they had witnessed. The informed part of this ethical principle is the most important part.

They found that misleading information did not alter the memory of people who had witnessed a real armed robbery. Elizabeth Loftus is an American cognitive psychologist and expert on human memory. Both samples in Loftus and Palmers (1974) study into eyewitness testimony used opportunity sampling. Dependent variable: Participants answer to the critical question: Did you see any broken glass? (either: yes or no). different speed estimates in experiment one were due to a By deliberately manipulating the IV we can see the causal effect on the DV. 26-35 year-olds were most accurate ( 77%) and the elderly (age 65+) group were the least accurate ( 56% ). glass whereas, 34/50 students did not recall seeing compared to those who got the verb, hit where the speed Loftus and Palmer did they by seeing Outline two ethical issues from loftus and palmer research.
