In Experiment 1, Loftus and Palmer found that the verb used in the critical question affected participants’ speed estimates of a car crash. The word “smashed” produced the highest mean speed estimate (40.8 mph), while “contacted“ produced the lowest (31.8 mph). This demonstrated that more intense verbs led to higher speed estimates, suggesting that memory can be distorted by the wording of a question, supporting the idea of response bias.
