EXPERIMENT I
Method
Forty-five students participated in groups of various sizes. Seven films were shown, each depicting a traffic accident. These films were segments from longer driver's education films borrowed from the Evergreen Safety Council and the Seattle Police Department. The length of the film segments ranged from 5 to 30 sec. Following each film, the subjects received a questionnaire asking them first to, "give an account of the accident you have just seen," and then to answer a series of specific questions about the accident. The critical question was the one that interrogated the subject about the speed of the vehicles involved in the collision. Nine subjects were asked, "About how fast were the cars going when they hit each other?" Equal numbers of the remaining subjects were interrogated with the verbs smashed, collided, bumped, and contacted in place of hit. The entire experiment lasted about an hour and a half. A different ordering of the films was presented to each group of subjects.

Mijn vraag is, waarom de groep die 'contacted' als woord kreeg, niet genoemd is als groep 5.
