What were the findings of the Loftus and Palmer study?
Findings: The estimated speed was affected by the verb used. The verb implied information about the speed, which systematically affected the participants’ memory of the accident. Participants who were asked the “smashed” question thought the cars were going faster than those who were asked the “hit” question.
What type of research method did Loftus and Palmer use in their car crash studies?
What type of research method did Loftus and Palmer use in their car crash studies? Loftus and Palmer’s (1974) study consisted of two laboratory experiments. Both experiments used an independent measures design, with the participant’s only taking part in a single condition.
What was the significance of Loftus smashed versus contacted study quizlet?
Smashed, hit, collided, bumped, contacted. Leading questions do effect memory recall. In this case changing the verb in the question to smashed gave a higher estimation of speed by the participants.
What has Dr Elizabeth Loftus discovered about our minds in terms of repressed memories?
She has conducted research on the malleability of human memory. Loftus is best known for her work on the misinformation effect and eyewitness memory, and the creation and nature of false memories, including recovered memories of childhood sexual abuse….Elizabeth Loftus.

How is Loftus and Palmer High in validity?
However, Loftus and Palmer’s research took place in a laboratory of Washington University and was therefore highly controlled. This high degree of control reduces the chance of extraneous variable, increasing the validity of the results.
What research method was used in Loftus and Palmer 1974?
Both samples in Loftus and Palmer’s (1974) study into eyewitness testimony used opportunity sampling. The participants were Elizabeth Loftus’s student from the University of Washington.
What sampling method did Loftus and Palmer use?
opportunity sampling
Experiment 2 Both samples in Loftus and Palmer’s (1974) study into eyewitness testimony used opportunity sampling. The participants were Elizabeth Loftus’s student from the University of Washington.
What is the car crash experiment?
The Car Crash Study was done in 1974 by Loftus and Palmer that was aimed to test their theory that the language used in an eyewitness testimonies can alter the eyewitness’s memory of the event. They got 45 American students and showed them 7 films of traffic accidents, ranging from 5 to 30 seconds, in a random order.
What type of research method did Loftus and Palmer use in their car crash studies quizlet?
Loftus and Palmer’s experiment is that the research is in an artificial lab setting so they were able to control the key variables in the study. This meant they could control the IV and stood a better chance of of controlling the extraneous variables which couldn’t have been controlled in a field experiment.
What was the significance of Loftus smashed versus contacted study?
Overall, the participants exposed to the verb ‘smashed’ gave higher speed estimates (average of 56.54km/h) compared to the ‘contacted’ condition (average of 42.35km/h). The results showed a clear link between the verb used and speed estimate recalled which is similar to Loftus and Palmer’s original study.
What controversial method did Elizabeth Loftus employ in her research?
The lost-in-the-mall study by Dr. Elizabeth Loftus concludes that an entire false memory can be implanted by suggestion. It has since been used to discredit abuse survivors’ testimony by inferring that false memories for childhood abuse can be implanted by psychotherapists.
Why was Elizabeth Loftus research significant?
Elizabeth Loftus studies human memory. Her experiments reveal how memories can be changed by things that we are told. Facts, ideas, suggestions and other post-event information can modify our memories. The legal field, so reliant on memories, has been a significant application of the memory research.
What was the purpose of Loftus and Palmer 1974?
Two experiments were conducted to examine framing effects in sport. In Study 1, a conceptual replication of Loftus and Palmer (1974), participants watched a hockey collision, with the hit described later in a written format as either a ‘contact’, ‘bump’ or ‘smash.’
What are the leading questions in the car crash study?
The participants were first asked an open-ended question: “Give an account of the accident you have just seen”, which was followed by a series of specific questions about the accident. There was one critical question that asked “About how fast were the cars going when they … each other”.
How did Elizabeth Loftus and John Palmer test their hypothesis?
In 1974, it was tested by Elizabeth Loftus and John Palmer. The two psychologists set out to test if language can alter testimonies. There were two different experiments, both testing the same hypothesis. Experiment One: Forty-five students were asked to participate in a laboratory study in which they would be entered in one…
What did Loftus and Palmer study about verbs?
In the following two experiments, Loftus and Palmer first studied the effects verbs in questions on speed estimates and also if these verbs could impact memory in other ways. The following information has been adapted from our textbook, IB Psychology: A Student’s Guide.
