These results illustrate a similar effect reported by Loftus and Palmer (1974). In their classic study, Loftus and Palmer showed that, after watching a video of a car crash, participants’ memories of the crash were influenced by information they received after they witnessed the event. For example, participants who were asked “how fast were the cars going when they smashed into each other” rated the speed the cars were going as much faster compared to participants who were asked “how fast were the cars going when they hit each other.” Furthermore, a week later participants asked the question with the word smashed were more likely to say there was broken glass at the scene (when in fact there was not) than those asked the question with the word “hit.” (see Table 2.) Even though all participants witnessed the same event, these results show how our memories are sometimes influenced by information provided after we have witnessed the actual event.
