Loftus and Palmer's conclusions. Considerable research by Loftus and Palmer (1974) has shown that memories on eye witness testimony are unreliable. Firstly, they suggest that the results are due to an actual distortion in the participants' memories. for real events. 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.

In this and other publications (Loftus et al., 1975; Loftus & Zanni, 1975), Loftus and her colleagues have demonstrated that, at a minimum, postevent questioning 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.

This investigation was a partial replication of Loftus and Palmer's (1974) experiment: Reconstruction of Automobile Destruction. 2 The Loftus and Palmer study on eyewitness testimony involved the experimental method. -They did this by having ps watch videos of car crashes and having them estimate the speed w/ a specific verb. . No because in 4 of the films, the speeds were: 20mph, 30mph, 30mph and 40mph yet P's estimated speeds between 36mph and 40mph. About how fast were the cars going when they smashed each other? One of the most commonly used research design is the laboratory experiment. Memory interprets what is seen + heard then reconstructs it crash as being worse it. This implies that misleading information may have a greater influence in the lab rather and that Loftus and Palmer's study may have lacked ecological validity. They found that misleading information did not alter the memory of people who had witnessed a real armed robbery. 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. real life a largely unexpected. The easy solution is to choose two. Name and describe the three effects described by Loftus (1991) that play a primary role in memory impairment. research. Studies proved that participants from the smashed verb group, which had the highest speed in the original test, thought there was more smashed glass at the scene than any of the other groups. Estimating vehicle speed is something people are generally poor at and so they may be more open to suggestion. ", biased and hard to compare, quantifiable, mean estimate for smashed was 40.5 mph whereas mean estimate for contacted was 31.8 mph, comparible, no reasons, mean estimate for smashed was 40.5 mph whereas mean estimate for contacted was 31.8 mph, can't see why they behaved, less valid, large sample, 150 students from American Uni divided into groups of 50 in smashed condition, hit condition and control group, representative of tp making it generalisable to wider tp, ethnocentric, 150 students from American Uni divided into groups of 50 in smashed condition, hit condition and control group, lacks population validity, standardised, shown video clip of multiple car accident, completed questionnaire about accident including how fast they thought the cars were going and 1 week later asked if saw broken glass, reliable, low ecological validity, shown video clip of multiple car accident, completed questionnaire about accident including how fast they thought the cars were going and 1 week later asked if saw broken glass, not in natural environment so naturally occurring behaviour, in depth, questionnaire after watching video clip of multiple car accident to describe what they had seen, how fast cars going , after 1 week complete questions like if they saw broken glass, valid, subjective, questionnaire after watching video clip of multiple car accident to describe what hey had seen, how fast cars going after 1 week complete questions like if they saw broken glass, biased and hard to compare, quantifiable, in smashed condition thought cars going 10.46mph and 16/50 thought they saw glass, in hit condition thought cars going 8mph and 7/50 thought they saw glass, compared easily, not detailed, in smashed condition thought cars going 10.46moh and 16/50 thought they saw glass, in hit condition thought cars going 8mph and 7/50 thought they saw glass, can't see why they behaved, less valid, Discrete Mathematics and Its Applications.
