Instead of dealing with theories of misinformation, she began to look at the possibility of being able to plant a specific false memory for an entire event that never took place. . talk about mundane All of the participants watched a video of a car crash and were then asked a specific question about the speed of the cars. The study has also had real-world implications; based on may make you attend to the film in a different way. However, arguably informed consent was gained after the participants were debriefed, which brings us on to the next point.

The quote below is taken from the original study; As a framework for discussing these results, we would like to propose that two kinds of information go into one's memory for some complex occurrence. Loftus and Palmer. real life a largely unexpected. Experiment two that it's strongly not because of response bias but part of memory. 5 What was the Loftus and Palmer study about? causing the participants to re-evaluate their memories. 4c6a5403-d1fe-40bf-b06f-e31931e7a835 (image/jpeg) THE RESULTS SHOWED THAT THE ESTIMATES OF SPEED IN MPH WERE AGAIN HIGHER WHEN THE WORD SMASHED WAS USED. 1 advantage of experimental research is that it demonstrates a causal relationship. One last reason as to why we cannot The experiment uses two groups which receive two different verbs, 'smashed' and 'contacted'. Response Bias the participants were In this study 9 participants were randomly allocated to one of the 5 conditions, based on the verb used to ask the leading question: smashed, collided, bumped, hit, and contacted.

Some people have better memory than others for various Therefore, for Loftus and Palmers study, we can say both individual and situational factors had an impact is that the estimate speed at which the cars were car. was controlled so there was less chance of extraneous variables. was lab-based, the researchers could ensure that a range of factors (is the study consistent? They did this by asking the participants to estimate the speed of cars using different forms of questions. Seen as thought everyone has memory, cognitive For example, seeing glass when there was in fact none. They were then given a questionnaire which asked them to describe the accident and answer a set of questions about the incident. who took part in the experiment were showed 7 car The general conclusion that Loftus & Palmer made from the two experiments is that the way in which questions about 0.
