- 3Method: both studies were lab experiments using independent measure design. The possible words were smashed, collied, contacted, bumped + hit.EX1. After watching the clips each group was asked "how fast was the car going when it ? the car?"
- 4EX2. 2/3 group were asked with the words smashed and hit. The other group was not asked a question at all.A week after the experiment, the third group were asked to complete a questionnaire which had the question "Was there any broken glass?"
- 5Results EX1: 'Smashed' produced the fastest speed estimate and 'contacted' the slowest.
- 6EX2: Again 'smashed' was highest. More pp's in the 'smashed' group recalled seeing broken than both the 'hit' and control group.
