Psychologist Elizabeth Loftus has been particularly concerned with how subsequent information can affect an eyewitnesss account of an event. This week I am going to be exploring this type of experiment and underlining why I believe the weaknesses of laboratory experiments outweigh the strengths. Thus, the procedure for collecting witness testimony has changed a lot since then. The witnesses had observed a gun shooting incident on a spring afternoon in Vancouver, Canada.

Unfortunately research shows that our memories are not as stable or as accurate as we think they are. Loftus and Palmer (1974) Researchers showed participants film clips of actual car accidents and then gave them a series of questions to answer. In this experiment loftus and palmer argue that two things can be happening: Distortion and Response Bias. In this experiment they showed participants a video of a car crash and asked .

This was falsely recalled by 12% of the Control group (who had never been asked about the speed of the cars) and 14% of the " hit " group; however, 32% of the " smashed " group .
