- Conclusions
- the verb used in a question influences a participant's response
- people are not good at guessing vehicular speed
- misleading post event information can distort memory
- 2 kinds of information make a complex occurrence: information gleaned during the perceptions of the original event + post event information
- Theories
- Schema theory - memory is influenced by what we already know
- Schemas - simplifie, generalsied mental representations
- Bartlett - reconstructive memory theory
- Procedure
- EXPERIMENT 1: -shown 7 different films - given a questionnaire with a critical question - the question was 'About how fast were the cars going when they hit/smashed/collided/contacted/bumped each other -l
- EXPERIMENT 2: - one minute film of a 4 second car crash - given a questionnaire with a critical questionnaire- the question was "About how fast were the cars going when they smashed/hit each other?' (the control group were not asked this question) - a week later they were asked whether there was broken glass in the video or not (there was no glass in the original video)
- Findings
- EXPERIMENT 1: smashed - 40.5 collided - 39.3 bumped - 38.1 hit - 34.0 contacted - 31.8
- EXPERIMENT 2: smashed - 16 yes, 34 no hit - 7 yes, 43 no control - 6 yes, 44 no
- Variables
- EXPERIMENT 1 - IV: wording of a critical questions DV: estimated speed
- EXPERIMENT 2 - IV: wording of a critical question in a questionnaireDV: whether they thought there was broken glass or nor
- Aim
- To see the effects of 'leading questions; on an individual's ability to accurately remember events
- Background
- Distortion of memory - certain features of a situation can bias a memory
- Research Method
- laboratory experiment, independent groups
- Sample
- EXPERIMENT 1: 45 students split between 5 groups EXPERIMENT 2: 150 students split between 3 groups
