SPSS LAB Assignment: ONE-WAY ANOVA How accurate are eyewitness memories? In a classic study Loftus and Palmer (1974) investigated how the language used after an event could distort eyewitness memory accounts. Participants viewed a film depicting a traffic accident. Following the film, the subjects received a questionnaire asking them describe what they remembered from the film and then to answer a series of specific questions about the accident. The critical question was the one that interrogated the participant about the speed of the vehicles involved in the collision: "About how fast were the cars going when they hit (or smashed, or bumped) each other?" Participants were randomly assigned to receive one of three versions of the critical question, each with a different verb: hit, smashed, or bumped. Is eyewitness testimony biased by the way questions are asked? Enter the data below into SPSS to determine if there are significant differences in perceived speed based on the verb used to describe the accident.
