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…
Elizabeth Loftus started studying this memory process in 1970. In one study, she showed some people a simulation of a car accident. After watching the simulation, one half was asked how fast they thought the cars were going when they “hit” each other and the other half was asked how fast they thought the cars were going when they “smashed” into each other. The half that was asked about the speed using the word “smashed” said the cars were going faster than their actual speed. Furthermore, in the experiment they were priming the subjects, training their memory using the…

Loftus and palmer were interested in seeing how misleading questions affected eyewitness testimony, they conducted a lab experiment in which 45 students were shown films of traffic accidents, they were then asked a question about how fast the car was going, students were either given the verb hit, smashed, contacted, collided or bumped. The group with smashed estimated the highest speed whereas the group given the word contacted estimated the lowest speed, this suggests that leading questions have a significant effect on memory. Loftus et al conducted another lab experiment to assess the effect of misleading info on EWT.…
In your textbook, a study was discussed in which participants were asked to complete two tasks at once or separately, and their performance in both conditions was compared. It was found that when they performed both tasks at the same time, they did not perform as well as when the tasks were performed separately. This experiment employed _____.…
Baddeley also found that when participants were shown words and asked to recall them immediately, they did so much better for sentences than for unrelated words which supports the idea of the episodic buffer- an immediate memory store for items that aren’t visual 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.…
Harrison’s review discusses her research of the First People’s Hall that is in Quebec. She discusses about the history and the development of the museum (293-294). She explores more in detail of what is in the four areas (295-298). The four main are: “Greeting and Orientation, Diversity and Origins, Survival and Cooperation in Ancient History, and Arrival of Europeans and Modern Existence” (295). Harrison includes the description of each area and of what is on display. The artifacts in the museum lacked important details and required visitors to have prior knowledge. For example, the lacrosse stick that is on display (298). Not all visitors would know what lacrosse is. She addresses the issue which is her main point is that people did not engage in deep conversations in the galleries, rather they talked about what they were observing but into detail. (299).…
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.…
2. Describe the experimental procedure. In this experiment I was presented by 14 trials in which I had to identify what I see in an ambiguous figure. Each trial contained several pictures presented one by one, followed by the test question about my perception of those multiple ambiguous figures. Once the ambiguous figure stopped there was a test question to choose between several options to describe what in my opinion the right answer as I perceive. Once I completed all 14 trials, the data was accumulated and presented in a graph comparing global views with myself.…

To investigate the effects of exercise on mathematical problem-solving ability, a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising, both groups did a set of math problems.…

Experiment: The purpose of this experiment was to test which variables affected the horses sympathetic nervous system leading the horse to stress and drooling. There were multiple variables tested such as the dilation of the horses eyes, if the horses ears were up and lastly if the horse drooled. In order to conduct this experiment, we had one horse getting honked at by a car and then testing those variables to…
This experiment had a ‘within-subjects’ design, because all of the participants were experiencing the independent variable. In this experiment there were three levels of independent variables. These were new words, old words and lures. The dependent variable of the experiment was a task where participant were to rate how…
