Aim: To investigate the accuracy of memory in particular how leading questions affect memory
Participants: 45 University students later divided into 5 groups
Procedure: They were shown 7 clips of car accidents orignally part of driver safety films
- After the clips the participants were given a questionnaire; with a critical question that said 'About how fast were the cars going when they hit each other'. This was given to one of the groups
- The other groups had the same question but 'hit' had been changed to 'contacted' 'smashed' 'collided' or 'bumped'. There was 5 experimental groups.
Results: The mean speed for all the conditions were calculated and are as follows; Smashed; 40.8, Collided: 39.9, Bumped: 38.1, Hit: 34.0, Contacted:31.8.
Smashed had the highest mean speed and Contacted had the lowest showing how leading questions affect memory.
