Findings proved that the participants that were asked the question with the verb “smashed” reported that the cars were going faster than the participants who were asked with the verb “hit.”ġ45 students were shown a video of a car driving down a countryside and then in the last four seconds, the video showed a multiple car accident. This was done to see if the change in the verb has an effect on the speed that the participants answered. Each participant was asked that question but the missing verb could be any of the following: smashed, collided, bumped, hit, or contacted. The main focus question was “About how fast were the cars going when they _ each other?” The blank represents where one of the five conditions would be placed.
