Cognitive (CLASSIC) - memory - LOFTUS & PALMER Flashcards
describe reconstructed memories
original event info - what was actually seen
this combines with
post event info - your expectations/ influence on others
to form
reconstructed memory - now merged and unable to separate
define schemas
knowledge is stored in memory in a set of schemas which are simplified, generalized mental representations of everything an individual understands by a given type of object or event based on their past experiences
define memory
our capacity to be able to retain and store memory
background
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
define leading question
questions that in some manner imply or lead to a desired answer
aim
- to investigate the role of leading questions on the memory of an event
- to see if the change in a verb could affect the memory of what what was seen
research method
lab experiment
sampling method to obtain participants
opportunity from washington uni
procedure experiment 1
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
exp 1 IV and DV
IV- verb used to describe the incident (smash, collide, hit, bumped, contacted)
DV- estimated speed of the cars in mph
exp 1 results
smashed - mean estimate speed 40.5 mph
contacted - mean estimate speed 31.8 mph
ex 1 conclusions
- 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
- 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
procedure experiment 2
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
exp IV
IV - speed of cars with different verbs but only hit, smashed or control group who were not asked about the speed of the car
exp 2 results
mean speed for the smashed condition was 10.46 mph compared to 8.0 mph for the hit condition
16 participants in the smashed condition said there was broken glass compared to 7 saying yes in the hit condition
