Aim- To see how the accuracy of eye witness testimony changed by leading questions
Procedure- 45 students were shown a video of a car crash. They were then split into 5 or 6 different groups and asked questions about how fast the car was going. Instead of the word fast some of the groups had other adjectives such as smashed, bumped collided, contacted.
Findings- Those who got the word contacted estimated a speed of about 31mph whereas those who got a speed of smashed estimated 41mph 10 more than others even though they had seen the same video.
Conclusions- This showed that ewt was generally inaccurate and unreliable. However, this study has helped to improve techniques now about leading questions.
