Evaluate The Difference Between Loftus And Palmer
Discussion:

The findings of this experiment suggest different results from the original experiment carried out by Loftus and Palmer in 1974, as there was no significant difference between the estimated speeds between the two groups because the results were not statically different. The descriptive results showed that the participants in the smashed group estimated a higher speed than the participants of the contacted group, (smashed group estimated a speed of 61.375 whereas the contacted group estimated a speed of 49.5), however the Mann-Whitney U test values indicated that the difference wasn’t significant enough to differentiate between the two conditions and so the difference was due to chance. The results reject the experimental hypothesis and support the null hypothesis that states that the use of the word “smashed” in the critical question will have no effect on the speed estimated. As my results are different to the original experiment carried out by Loftus and Palmer I suspect that there were some limitations in my attempt to replicate the experiment.

One reason for this could be the limited amount of data caused by the limited amount of participants. The results would probably be more accurate if the sample size of participants had been

I would use a random sampling technique in order to have a more variety of participants, as only business and sociology students were used. I would include participants all of ages in order to have a higher variety. Furthermore I would use a higher number of participants and I would carry out a repeated measures design, in which participant would have to watch several clips and respond several questionnaires. Moreover I would conduct the same experiment in other topics rather than only in the estimation of car speed, for example testing if the phrasing of the question affects the ability to estimate a human

    Experiment M1 was designed to familiarize us with how to take measurements with motion sensors, inferring graph such as time vs velocity and time vs position, and differentiating random and systematic error in an experiment. During activity 1 we begun by standing in front of motion sensor at a distance of 1.2 meters and varied our distance by 0.6 meters over the course of 25 seconds. This activity presented us with a position vs time graph that we were supposed to replicate to our best ability. For activity 2 we are given a position vs time to replicate and after replication a velocity vs time graph is created below. The graph showed that, though the position raises, evens out, and then returns to initial position; the velocity spiked positively, dropped negatively, and then evened out. During activity 3 we discussed the terms average value, random errors, systematic errors, accuracy, precision, and standard deviation. Using the equations provided in the text, we are able to calculate the average value and the standard deviation using the average value of both trails. After both calculations on each trial we were able to come to the conclusion that, increasing the range of results ultimately increased the standard deviation and random errors. The increase in standard deviation and random error lowered the accuracy of the trial. Theoretically, by closing our eyes in trial two there should have be an increase in standard deviation, random error, and a lower accuracy; in our results however, the second trial had a .000044 lower standard…

    I will be surveying 500 students. 250 alternative high school students and 250 charter high school students, between the ages of 18-19, because it would be easier for them to participate in this design without parental control. I will be specifically doing this research in the Lawndale area, on the west side of Chicago. Personally me growing up in Chicago I have knowledge about this area, because this is where there are single-family households, low income, and lots of crime take place here. I have two purposes for using surveys. The first purpose is to get the public opinions (students) on dealing with poverty crime to help improve some of the difficult defects that exist within those main areas. Another reason why I chose surveys is so that I can reach out to different high schools, where I can get the younger population educated on, crime and how not to let it affect them. Also, there were three different surveys that I had to choose for my research proposal, which were questionnaires, mailed surveys, and telephone surveys. I decided to use questionnaires. I will be asking a series of questions related to both property crimes and serious violent crimes they had committed in the past year. First, students were asked 3 questions related to property crimes. “In the past year, how many times did you want to steal something for your local mall”? 0 = never, 1 = 1-2 times, 2 = 3-4 times, and 3 = 5 or…

    Loftus was concerned with how subsequent information could affect an eyewitness testimony (EWT) which is a legal term, referring to the use of eyewitness to give evidence in court. EWT can be influenced by misleading information in terms of both visual imagery and wording of questions. This could lead to faulty or incorrect convictions. If someone is imposed to new info during the interval between witnessing the event and recalling it, this info may have marked effects on what they recall. Original memory can be modified.…

    The Loftus and Palmer study is a laboratory experiment. This means that the study is artificial. The artificiality of the setting can intimidate participants or make them more obedient. This in turn can produce unnatural behavior and results that do not generalize to real life. This can be seen in experiment 2 when 12% of the control group reported seeing broken glass even though they were unaffected by the verb. This could be attributed to the leading question or to demand characteristics when participants look for cues as to what the research is about and behave accordingly, perhaps to please the researcher, especially as the participants in this case are students that may even be familiar with the researcher as they are from the same environment. In a nutshell, due to the nature of the experiment, it lacks ecological validity. In a real life situation there would be an element of surprise and an increase in emotion. Basically the eye-witness would be in some way involved, which is not the case while watching the video the eye-witness is not part of the event. Furthermore, an eye-witness in a real life situation may discuss the event with other people which may alter their memory of the event. Lastly, an eye-witness may think more carefully about giving an answer when in a real life situation when they realize that their answer could judge how innocent or guilty a person is, they may hesitate and realize the importance, although when taking part in a study they may just give an answer without as much thought.…

    Loftus and Palmer Review

    • 4 Pages

    In Experiment 1 it was hypothesized that when the subject hears the word “hit” instead of the word “smashed” they will think that the collision was gentler. Loftus and Palmer came to this conclusion based on a previous experiment conducted by Bransford and McCarrell in 1971. The hypothesis in Experiment 2 was that the subjects would think that the glass had been broken if they heard the word smashed, instead of the word hit, or even if they weren’t asked to estimate the speed initially. This was supported by the findings of Bransford and McCarrell in 1971 because once again it was suspected that the subjects would think the collision was more violent if the verb smashed was used. (Loftus & Palmer, 1974).…
