Why was it a good idea to ask 10 questions rather than just asking the critical question alone? They were then questioned about the film. (note any relevant This example served to demonstrate some of the ways in which memory operates: by constructing and reconstructing information, based on what was observed and the previous information which we hold. research.

One last reason as to why we cannot This study is Loftus and Palmer on Cognitive Psychology. Findings: The speed that the eyewitnesses reported was affected by the particular verb that was used, since the verb implied information about the speed. After watching the film participants were asked to describe what had happened as if they were eyewitnesses. They were then asked specific questions, including the question About how fast were the cars going when they (smashed / collided / bumped / hit / contacted) each other?.
