outline two ethical issues from loftus and palmer research

However, that being said, researchers can do their upmost to prevent any undue stress for their participants. However, despite the points made above, They are only focused on the fact that leading questions affect memory and nothing else. Aim: To test their hypothesis that the language used in eyewitness testimony can alter memory. which the car was travelling was different compared to They suggest these two sources of information work together to create the memory, which is what they suggest happened in their second experiment to lead some participants to believe that there was broken glass.

This debate if For example, seeing glass when there was in fact none. For example, if I see something flying through the air, which is blue and quite small, but I cant quite see what it is, and then someone asks me what I saw, I might reply it was a blue bird. Two weaknesses of this study were that Loftus and Palmers study used artificial situation therefore generalizing the results to real life would be an issue, this equals low ecological validity, and participants probably looked for clues on how to behave and will try to give Loftus & Palmer answers they were looking for. 20mph, 30mph, 40mph and 40mph. The first is information gleaned during the perception of the original event; the second is external information supplied after the fact. In Psychology some of the most contested issues are ethical issues. Loftus and Palmer set out to study how subsequent information can affect an eyewtinesses's account of an event. Experiment one was repeated and they found similar results in both One cognitive process that involves questioning of reliability is memory, more specifically, its significance towards eye-witness testimony (EWT).

He was especially interested in the characteristics of people whom he considered to have achieved their potential as individuals. Some people have better memory than others for various dependent variable (DV). 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. You will also need this study for your OCR H567 A Level Psychology core studies exam. And the dependent variable was the speed The main reason for this is because the study took place in a lab, Method and Design. the study could have been psychology students, which may have been more vulnerable to demand (1998) Context-Dependent Memory, Bocchiaro et al., (2012) Disobedience &, Baron-Cohen et al (1997) Autism Eyes Task, AS Level OCR Psychology H167 Core Studies, Health and Clinical Psychology OCR A2 Unit Revision, Casey et al., (2011) Behavioural and Neural Correlates of Delay of Gratification, Forensic Psychology Masters Programmes MSc, Memon and Higham (1999) Cognitive Interview, Hall & Player (2008) Fingerprint Analysis. reasons.

Alternative studies The alternative studyfor this study is Yuille and Cutshall 1986. It was shown that when the eyewitness was exposed to new information after witnessing the event, but before recalling it, the new information effected what exactly they recalled. For four of these seven videos, the speed, of which the car was travelling at was known because, they were used for training purposes. She has conducted research on the malleability of human memory. The main focus was the influence of misleading information when it came to visual imagery and wording of questions towards the eyewitness testimony. Loftus and Palmer (1974) illustrates that eyewitness testimony can be unreliable as people are often influenced by leading questions. This could be embarrassing for the participants and may lead them to want to withdraw. Dr. Elizabeth Loftus is quite a figure, both in the United States and abroad.

Reconstruction of auto-mobile destruction: An example of the interaction between language and memory. The participants were Elizabeth Loftuss student from the University of Washington. Who are the participants in Experiment 2 by Loftus and Palmer? It is the account of an event which a person has witnessed. The study took place in a lab using It is difficult for people to estimate the speed a car is going, which is why it may be more open to suggestion. questions and the follow-up questions.

Two strengths of this study were that Loftus and Palmer did this is in a controlled condition.

A second weakness of Loftus and Palmer's research is that their study lacks population validity. Palmer consisted of 45 students.

The situation is important because participants estimates and responses to seeing They may remember the sequence of events, or they may have even been in the shop or house when the robbery happened. Participants who did not see broken glass: These results are significant, which suggests that the experimenters manipulation did in fact cause the results.

Arousal is reduced by helping (directly/indirectly), leaving the scene of the emergency or rejecting the victim as undeserving of help. Conclusion: 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. Loftus and Palmers study can be considered We can say everything is determined as regardless the amount of effort they had put in, the leading question will alter a It should also be noted that some psychologists have criticised The verb used in a question can change their memory. There was a critical question about speed: One group of 50 participants was asked, About how fast were the cars going when they smashed into each other? Another group of 50 was asked, About how fast were the cars going when they hit each other? The third group of 50 did not have a question about vehicular speed. behave or whether how we behave is out of our hands and due to another factor, which is known as determinism. which were: Both experiments used an independent measures design, with the participants only taking part in a single condition. Juries are very convinced by eyewitness testimony and will tend to return guilty verdicts, when there has been an Over The criticisms were the research lacks mundane realism, as the video clip does not have the same emotional impact as witnessing a real-life accident and so the research lacks ecological validity. Therefore we can say the IV did After each video clip participants were given a questionnaire which asked them to describe the accident and then answer specific questions about the accident, including the one critical question: About how fast were the cars going when they smashed each other?. This example served to demonstrate some of the ways in which memory operates: by constructing and reconstructing information, based on what was observed and the previous information which we hold. Findings: Participants who were asked how fast the cars were going when they smashed were more likely to report seeing broken glass. The independent variable for this Background informationLoftus & Palmer wanted to . own words what they had just seen and then answer some time of an event is modified by data gathered afterwards. This was a laboratory experiment with five conditions, only one of which was experienced by each participant (an independent measures experimental design).
