A study was conducted by Loftus and Palmer (1974) in which they investigated the effect of language on thought processes. In this study, participants viewed a video clip of a car accident. After the video, half of the participants were asked to estimate how fast the cars were going when they "smashed" into each other, while the other half were asked to estimate speed when they "hit" each other.
