Loftus and Palmer's car crash experiment is a classic study in the field of psychology that examined the impact of leading questions on memory. The experiment, conducted by Elizabeth Loftus and John Palmer in 1974, involved showing participants a film of a car crash and then asking them a series of questions about the crash. The researchers found that the way in which the questions were phrased significantly affected the participants' recollections of the event.
In the experiment, participants were divided into four groups and shown a film of a car crash. Each group was then asked a slightly different version of the same question: "About how fast were the cars going when they (smashed/hit/bumped/collided) each other?" The researchers found that the way in which the verb in the question was phrased influenced the participants' estimates of the speed of the cars. Participants who were asked the question with the verb "smashed" estimated the cars to be going faster than those who were asked the question with the verb "hit."
This experiment demonstrated the influence of leading questions on memory and the potential for language to distort our recollections of events. It is important to be aware of this effect when conducting interviews or gathering eyewitness testimony, as the way in which questions are phrased can significantly affect the accuracy of the information obtained.
The findings of the car crash experiment have been widely replicated and have had a significant impact on the field of psychology, particularly in the areas of eyewitness testimony and memory. The experiment highlights the importance of being mindful of the language we use when asking questions and the potential for our own biases and expectations to influence the responses we receive.

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. A comparison of the two groups of participants is likely to show that When presented with a lineup, Alexis was able to identify the perpetrator of a robbery she had witnessed. A further problem with the study was the use of students as participants. Ted makes plans to have dinner with his wife at 7. This has important implications for the questions used in police Consequently, Loftus and Palmer support the reconstructive memory hypothesis - arguing that information gathered at the time of an event is modified by data gathered afterwards.
Car Crash Experiment
The participants were unaware the experiment had begun. In 1974, it was tested by Elizabeth Loftus and John Palmer. Our visual system is only able to detect a small proportion of all the electromagnetic spectrum. There are potentially some problems with this methodology. You have a feeling that you read something about napalm lately and decide to chime in.
Loftus and Palmer Car Crash Experiment
One week after this setting, the students were asked to return and were asked if they saw broken glass in the accident scene. The use of identity parades to pick out possible suspects has often proved crucial in the courts arriving at a guilty verdict. John Palmer graduated from Duke University with a B. There are several reasons why practice can improve performance. Procedure Experiment 1 All 45 participants were shown the same seven film clips of different traffic accidents which were originally made as part of a driver safety film.
What was the purpose of the car crash experiment?
Independent Learning Tasks Draw a table showing the results of experiment one and draw a bar chart to show the results of experiment two. It was manipulated by asking 50 students 'how fast were the car going when they hit each other? Students are not representative of the general population in a number of ways. This is the classic cognitive psychology study which you will look at for your H167 AS OCR Psychology exam. Perhaps cases should not go to court when the main evidence provided is eyewitness testimony. Watching footage on TV is not the same as witnessing a real life car crash, so the experiment lacks ecological validity.

None of them know about the others. Participants viewed video clips rather than being present at a real-life accident. Red light is associated with long waves, relative to blue light. The photoreceptors communicate directly with the ganglion cells. They could have the stress of coming close to a person who perhaps assaulted them, also there could be anger involved, and they may pick anybody on the basis they want someone prosecuted for what happened to them. The physician expected to need the information later on and therefore employed a maintenance memorization strategy that she believed had helped her memorize material in the past. The independent variable was the type of question asked.

Which of the following statements was NOT supported by their findings? Consequently, they could ensure that these factors did not affectthe respondents answers - and that only the verb-condition wascausing the participants to re-evaluate their memories As an psychological explanation, the reconstructive memoryhypothesis is extremely useful; for instance, in formulatingguidelines in for police questionning of witnesses and suspects. Learning Check 1 Write an experimental hypothesis for experiment 1. This may have influenced them to be more swayed by the verb in the question. However many studies have been conducted over the years which suggest a number of ways in which eye witness testimony can be unreliable. The conclusion that leading questions can affect memory has important implications for interviewing witnesses, both by police immediately or soon after an event and also by lawyers in courtsome time later. They concluded that we are better at being able to recognise our own race. It was manipulated by asking 50 students 'how fast were the car going when they hit each other? She has conducted research on the malleability of human memory.

The results gave evidence that specific words could influence the retrieval of a memory. Interviewees are first asked to recreate the context of the crime, and then the witness is asked to talk of anything they remember in free recall, regardless of whether they perceive the information to be important or not. Use photographs or video clips of car accidents and write a set of questions, one of which will be the critical question. The verb implied information about the speed, which systematically affected the participants' memory of the accident. Studies and experiments by Elizabeth Loftus, Florida Atlantic University psychologists and many other psychologists provide evidence that supports the theory that memories can be altered and therefore eyewitness testimonies are not always Reconstruction Car Destruction replicate the study of Loftus and Palmer regarding the effect of language on memory.
Loftus and Palmer Experiment (1974) (2022)
The original memory can be modified, changed or supplemented. An experimenter reads a list of 30 words to a group of participants at the rate of one word per second. During the video a four-second there was a 4-second multiple car crash. RTs were faster for responses to valid cues relative to neutral cues. After the video the students were asked questions about the film. Steve is shown a list of words, which includes "baby.
