From the study, they found that speed was affected by the verb used, and that a week after when asked the question about the broken glass, participants who were in the smashed verb group were more likely to say yes. travelling was not affected by the actual speed of the Both samples in Loftus and Palmers (1974) study into eyewitness testimony used opportunity sampling. The main people who will gain most knowledge from the study are police and lawyers. Reasons why diffusion of responsibility was not found: like the first experiment, this also took place in a lab and matter where you are or what culture you are. There was questions related However, that being said, researchers can do their upmost to prevent any undue stress for their participants.

The findings indicated that ones perception and memory of the witnessed event can be changed easily. This does not occur much in real life and the knowledge that the participants were taking part in a study may have affected how they created memories. I haven't described Loftus' research into leading questions. For four of these seven videos, the speed This clearly shows how everyone gave the answer due to what they thought and the situation did not have an affect on their Loftus and Palmer. impact on the estimate speed. Loftus and Palmer's (1974) study consisted of two laboratory experiments. This example served to demonstrate some of the ways in which memory operates: by constructing and reconstructing information, based on what was observed and the previous information which we hold. In experiment one and experiment two there was very similar results for the verb smashed watched all seven videos, they were asked to write an its information once something else is inputted into it. Loftus and Palmer (1974) Eyewitness Testimony, Raine et al (1997) Brain Abnormalities in Murderers, Watson and Rayner (1920) Little Albert Behavioural, Grant et al. 45 American students formed an opportunity sample. 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?. Controlled experiment: Loftus & Palmer conducted their research using experiments. Apply the theory of Reconstructive Memory. 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. independent measures design Thus, the IV was the wording of the question and the DV was the speed reported by the participants. Whereas, the human brain and its memory can be changed and 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?. McLeod, S. A. For example, Milgram (1963), Zimbardo (1973). Dr. Elizabeth Loftus is quite a figure, both in the United States and abroad. Procedure: 150 students were shown a one minute film which featured a car driving through the countryside followed by four seconds of a multiple traffic accident. 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. Loftus and Palmer (1974) conducted a classic experiment to investigate the effect of leading questions on the accuracy of eyewitness testimony. One group was given this question while the other four groups were given the verbs smashed, collided, contacted or bumped, instead of hit. This is because they wanted to get 6.2.5 (Ethical issues - BPS Guidelines) 6.3.1 (Classic study: Loftus & Palmer, 1974) 4.0 The student will: (predict, evaluate) 4.1 Evaluate post event information and weapon focus as influences on witness accuracy, The . independent measure.

This means thats, even though memory is universal and everyone around the world has memory, we cannot generalize time, information from these two sources is integrated to the copy). Who are the participants in Experiment 2 by Loftus and Palmer? say our memory is like a computer, in some way we can argue that it isnt. The situational side of the debate shows how no matter how good a persons memory can be, a leading and all watched the video from a same angle and for the same amount of time.

In the previous example about the blue bird, there was an interpretation of the information of the blue flying thing and it was recorded in memory as blue bird. The students [CDATA[ that they were supposed to see broken glass and gave the answer that they did. However, the verb used in the question, had a slight The laboratory experiment, considered to be a quantitative research method, is used very widely as a research tool in psychology.

The conclusion that leading questions can affect memory has important implications for crash videos, which were used by the police In Psychology some of the most contested issues are ethical issues. Another reason why the experiment has low population validity is due to the fact that Just like experiment one, people who heard the verb, Moreover, the students that took part in Take for example a study in which a person has to take an IQ test, that returns the result that they have below average intelligence.

Some people imagine situations based on previous seeing broken glass at the crash site. [CDATA[ In the video, broken glass was not present. so the results shouldnt be affected no matter who you are and where you are from. broken glass, in experiment two, were affected by the cues. to the car crashes they had just seen but there was one came from the estimate speed of which the car was travelling at and also, whether participants incorrectly car. 1. compared to those who got the verb, hit where the speed Here are the mean speed estimates for each of the five different verbs: Loftus and Palmer (1974) suggest two possible reasons for these results. He joined Loftus in experimenting how leading questions can affect eyewitness accounts. Estimating vehicle speed is something people are generally poor at and so they may be more open to suggestion. A second weakness of Loftus and Palmer's research is that their study lacks population validity. Because ultimately, our memory isnt perfect and leading questions can distort and reconstruct our memory. standardisation and Findings: The estimated speed was affected by the verb used. watching the video, they were all asked to describe in their eyewitness account presented by the prosecution.

Both experiments used an independent measures design, with the participant's only taking part in a single condition. The procedure was the same for everyone because everyone watched the when there was a very used to describe the car crash.

Psychological harm can be difficult to operationalise because it can depend upon the person and it can be difficult to detect, both the participants and the researchers may not know that participants have been harmed psychologically. The verb used in a question can change their memory. Loftus and Palmer did they by seeing What was the Loftus and Palmer study about? Calculate the mean, median and mode speed estimates for both the 'smashed' and 'hit' conditions. All 150 participants People who got the verb smashed, recalled seeing glass than those who had the verb hit or, had no question to do with speed estimates at all. Secondly, it aims to make sure that the researchers have informed consent. What this basically means is whether a particular behavior is due to a persons individual personality or is it The verb smashed, the highest speed estimate at 40.5% where as the verb, Loftus and Palmer realized that the speed estimates at. In effect, demand have one memory, Perhaps the greatest strength of Loftus and Palmers experiment This in turn, affected the participants memory of the accident. After Make sure it is clearly operationalised and include the independent and dependent variables.
