Students are not representative of the general population in a number of ways. In other words, eyewitness testimony might be biased by the way questions are asked after a crime is committed.
Why was it a good idea to ask 10 questions rather than just asking the critical question alone? This was a laboratory experiment with five conditions, only one of which was experienced by each participant an independent measures experimental design.
Outline the quantitative measure used in this study. To investigate whether the use of leading questions would affect recall in a situation where participants were asked to estimate speed.
How do you think this may have effected their behavior? Outline one difference between the responses given between the two experimental groups. Biography[ edit ] Loftus grew up in Bel AirCalifornia. References report this ad Loftus, E. A leading question is a question that suggests what answer is desired or leads to the desired answer.
The participants knew they were taking part in a psychology experiment. In addition, some states no longer allowed prosecution based on recovered memory testimony and insurance companies were more reluctant to insure therapists against malpractice suits relating to recovered memories.
InDavid Corwin and his colleague Erna Olafson published a case study  of an apparently bona fide case of an accurate, recovered memory of childhood sexual abuse. A case study of eyewitness memory of a crime. Read the original article of the study. How to reference this article: Learning Check 2 Write an null hypothesis for experiment 2.
One week later the dependent variable was measured - without seeing the film again they answered ten questions, one of which was a critical one randomly placed in the list: As the video clip does not have the same emotional impact as witnessing a real-life accident the participants would be less likely to pay attention and less motivated to be accurate in their judgements.
This is because the method was a laboratory experiment which followed a standardised procedure. Sarmatian and gladsome Taddeus kern their whoosh or nucleated chummily. This is a situation that could happen when people appear in court as eyewitness testimonies.
She also emphasized that participants demonstrated no adverse effects upon follow-up and pointed out that the study design and findings had been replicated repeatedly, demonstrating the soundness of the conclusions.
The addition of false details to a memory of an event is referred to as confabulation. Thus, they aimed to show that leading questions could distort eyewitness testimony accounts and so have a confabulating effect, as the account would become distorted by cues provided in the question.
The impetus for this new line of research was a case for which Loftus had been asked to provide expert testimony in For example, they may be required to give a description of a robbery or a road accident someone has seen.
In this case the leading questions are created by using verbs with different intensities such as smashed and hit. Misinformation effect InLoftus accepted an assistant professorship at the University of Washington and used the new position to begin a new line of research into how memory works in real-world settings,    beginning the empirical study of eyewitness testimony.
Learning Check 1 Write an experimental hypothesis for experiment 1. Her main focus has been on the influence of mis leading information in terms of both visual imagery and wording of questions in relation to eyewitness testimony.
The results indicate that memory is not reliable and that memory can be manipulated by using specific words. The experiment was rigorously controlled so it was possible to establish a cause-effect relationship between the independent variable the critical words and the dependent variable estimation of speed.

Thinking like a Psychologist - Evaluating the Core Study and it allows statistical analysis to be conducted but it is fairly superficial and does not tell us anything Loftus and Palmer used student participants in both of the studies.
