In a classic study of human memory, Elizabeth Loftus (1975) asked two groups of subjects to watch a very short film about a traffic accident (the film itself lasts less than a minute, and the accident only a few seconds). In the film, a car runs a stop sign into oncoming traffic, ultimately causing a five-car, chain-reaction accident. The two groups were then given a questionnaire with 10 questions on it. For each group, only two questions were targets; the rest were just filler. For Group 1, the first target question was, “How fast was car A (the car that ran the stop sign) going when it ran the stop sign?” Group 2 was asked: “How fast was car A going when it turned right?” Both groups received the same final question on the form, which was, “Did you remember seeing the stop sign for car A?”
