The Loftus And Palmer Experiment

INTRODUCTION
The Loftus and Palmer experiment investigated the influence of leading information: visual imagery and leading questions with regards to eyewitness testimony. A research that studies this is the Loftus and Palmer (1974) Experiment. It aims is to investigate how “verb” asked in the question causes construction in one’s memory of that event. Participants will be separated into two groups one control and one test group, then both groups will view a video of a car crash. After that, the control group will be asked about how fast was the car going when they smashed into each other? And the test group will be asked about how fast was the car going when they hit into each other? As researchers identified an idea that estimated speed was affected by the verb used. They found that participants who were asked the words “smashed” in the question thought the car were going faster then using the word “hit” in the question. Researchers then concluded that the verb conveyed an impression of the speed the car was traveling and this change the participants perceptions. This study replicates the Loftus and Palmer research that aims to investigate the how “verb” asked in the
There are two conditions, the experimental group in which the participants were leading questions using suggestive verbs and the control group in which the participants were more open neutral questions. The dependent variable is the number of speed the car crash and the participants’ estimate from the car crash video. In this replication, we have decided to use independent design. Since we are looking for the difference in the participants’ estimates about the speed of the car, we cannot have participants participate in both conditions - experimental and control. Therefore, repeated measures cannot be used because after a participant’s has watched the video, the will be affected when they watch the second
