Loftus and palmer study

AbstractThis experiment was aimed to investigate the effect of language on reconstructive memory. The study consists of a laboratory experiment; it is an example of an independentmeasures design. The participants age ranged from and were all tested together tested once in a classroom during their lunch break. The participants were randomly given questionnaires after watching a video clip of a car crash.

Loftus and palmer study

The experiment involved two separate studies. In the first test, 45 participants were randomly assigned to watch different videos of a car accident, in which separate videos had shown collisions at 20 miles per hour, 30 miles per hour, and 40 miles per hour.

Afterwards, participants filled out a survey. The survey asked the question, "About how fast were the cars going when they smashed into each other? Rather than "smashed", other verbs used included "bumped", "collided", "hit", or "contacted".

Participants estimated collisions of all speeds to average between 35 miles per hour to just below 40 miles per hour. If actual speed were the main factor in estimate, it could be assumed that participants would have lower estimates for lower speed collisions. Instead, the word being used to describe the collision seemed to better predict the estimate in speed rather than the speed itself.

Those in the first condition were asked the same question as the first study using the verb "smashed". The second group was asked the same question as the first study, replacing "smashed" with "hit". The final group was not asked about the speed of the crashed cars. The researchers then asked the participants if they had seen any broken glass, knowing that there was no broken glass in the video.

The responses to this question had shown that the difference between whether broken glass was recalled or not heavily depended on the verb used.

A larger sum of participants in the "smashed" group declared that there was broken glass. In this study, the first point brought up in discussion is that the words used to phrase a question can heavily influence the response given.

We would like to show you a description here but the site won’t allow us. For more than 30 years, I have been studying a phenomenon called the misinformation effect (Loftus and Palmer ; Loftus ; Loftus and Hoffman ).The studies that we have done show how readily memory can become skewed when people are fed misinformation.
