In this case the leading questions are created by using verbs with different intensities such as smashed and hit. Police investigations. Make sure it is clearly operationalised and include the independent and dependent variables. In effect, demand A strength of the Loftus and Palmer study is that it is high in internal validity. -The study was considered very ethical. 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? Overall, we can probably conclude that this laboratory experiment had low ecological validity and thus . The tasks are not usually expected on real life, for instance you would not be normally asked to recall a short film.

They argue that we have no 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. Unfortunately research shows that our memories are not as stable or as accurate as we think they are.

The specific verb did cause a specific memory.-The study was considered very ethical. Give a piece of evidence to support this. It is reasonable to argue that the students in their experiment were less experienced drivers, who may be less accurate at estimating speeds. The central goal of Loftus and Palmers experiment was to establish the extent to which language influenced the perception of reality. Moray. Grant. It offers a lot of practical applications. Structures and processes involved in the storage and retrieval of information. trial judges be required to instruct juries that it is not safe to The cognitive area Discussion There was a clear indication that the increasing severity of the verb caused participants to give higher estimations of speed. This makes the statistical analysis far more complicated than it needs to be.

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. Given that it has just been argued that the study had an unrepresentative sample and had low 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.

To their age range strengths connected to lab experiments than the whole due! Describe one strength and one weakness of the experimental method used in this study. Clearly linked to the classic research. Two conditions only: The classic mistake in IAs is that students choose all five verbs - bumped, smashed, crashed, hit, and contacted. It should also be noted that some psychologists have criticised If you give misleading information in a police investigation, it could lead to the wrong person being convicted or accused of the crime, and the actual person who committed the crime getting away with it. In addition to what these discoveries imply in the field of judicial interrogations, its also clear that they have an effect on everyday life. Not everyone will think like a student. The findings into Eyewitness testimony were that 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 - Cognitive Assumption - 1, Human minds function similar to computers as they encode, store and output information. This happens in the mass media as they may report real facts, but control the format how they present the news. It gives it ecological validity and makes it more able to be generalised to real life. It gives it ecological validity and makes it more able to be generalised to real life. +5. suggest that participants could merely be following the - The third group did not have a question about speed. 2. the original procedure employed by Loftus and her col leagues. 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 argue that two kinds of information go into a person's memory of a complex event.
