AIM | Investigate the effect of leading questions on eyewitness testimony; and ability to estimate speed accurately. |
EXPERIMENT 1 | 45 student participants from University of Washington. Divided into 5 groups of 9. Shown 7 clips of traffic accidents from driver's safety film. Given a questionnaire after each clip, which has a critical question, placed in a random position on each participant's paper. |
CRITICAL QUESTION | ''About how fast were the cars going when they (smashed/collided/bumped/hit/contacted) each other?'' |
RESULTS (SPEED ESTIMATES) | 40.8/ 39.3/ 38.1/ 34.0/ 31.8 RESPECTIVELY (smashed/ collided/ bumped/ hit/ contacted). |
EXPERIMENT 2 | 150 students are divided into 3 groups of 50. Shown 1 minute clip containing 4 second scene of multiple car accident. Given a questionnaire to fill in but this time only Group 1 and 2 have a critical question. |
CRITICAL QUESTION | ''About how fast were the cars going when they (smashed/hit) each other?'' |
ASKED TO RETURN A WEEK LATER... | Without viewing the clip again, are asked: ''Did you see any broken glass?'' |
RESULTS | 16/ 7/ 6 say yes RESPECTIVELY (smashed/ hit/ no critical question). 34/ 43/ 44 say no RESPECTIVELY (smashed/ hit/ no critical question). |
FINDINGS | 1) Verb label distorts memory. 2) Information obtained from perceiving an event integrates with that supplied after the event so that we are left with 'one memory' and can no longer recall which source which piece of information came from. |
