Q

background

A

Bartlett’s 1932 theory of reconstructive memory forms the basis for L&P study. Bartlett found that when people remember stories they leave out some details and introduce rationalisations to make the story sense. He found when retelling new information people made errors as they use their schemas to interpret the story and provide information which they think would be included rather than what was actually there

45 students took part and watched 7 different films each depicting 9 different traffic accidents. Films ranged from 5-30 seconds long
following each clip participants given a questionnaire and asked to give an account of what they saw. Then asked specific questions about the accident. Critical question included that interrogated the participant about the speed of the cars involved in the collision. Question embedded among filler questions

Q

ex 1 conclusions

A
  1. memory is altered/reconstructed memories - critical questions and the verb changes a persons memory so they actually see the the accident differently, more or less severe
  2. response bias - different speed estimates occurred because the critical word influences or biases a person’s response - our ability to judge speed is not accurate

Q

procedure experiment 2

A

150 students shown 1 minute film containing a 4 second multiple car crash. Then given a questionnaire which included a space to describe what they had seen and answer a set of specific questions about the accident
One week later they were asked another questionnaire after not seeing the film again if they saw any broken glass

Q

overall conclusions

A

when verb smashed was used in the critical question about the speed, the mean speed estimate was 40.5 compared to when the verb was contacted was 31.8 suggesting the verb in a question influences a participant’s response
in experiment 2 more participants in the smashed condition reported seeing broken glass than those in the hit condition even though there was no broken glass implying that misleading post event information can distort an individual’s memory
